Johannes Knittel - The Symbiosis of Visualization and AI: Explaining Large Models and Obtaining Insights into Big Data

When: Tuesday 17th of January, 14:30h
Where: Amphitheatre, Bat 660 How to get to there?

Abstract:

The combination of machine learning and visualization has received increased attention in recent years, in part due to the impactful advances of recent neural architectures and models for natural language processing and human-like text or image generation. In this talk I will first summarize and characterize the different aims and tasks of recent approaches that combine ML and VIS. The main goal of my talk is to illustrate the symbiosis of interactive visualizations and machine learning techniques for two important pillars of VIS and ML: visually explaining large (language) models and obtaining more comprehensive insights into big datasets. Several visual analytics approaches have been developed to better understand, assess, and debug machine learning models, taking advantage of the fact that we can benefit from our visual cognition for pattern mining in addition to simply parsing the outputs of algorithmic analyses. However, interpreting what a model has learnt may also reveal interesting insights about the training data itself. I will talk about that, on the one hand, making ML models more visually interpretable not only helps to better understand said models, but it also offers new ways of leveraging advanced ML techniques to extract and visualize more complex, multidimensional relationships in large datasets. On the other hand, developing better ways of visualizing large corpora as well as multidimensional relationships will also advance the visual analysis of machine learning models with ever growing sets of weights and training data.

Past talks

Narges Mahyar and Ali Sarvghad - Designing and Building Tools for Fostering Equity and Inclusion in Civic Decision-Making

WHERE: PCRI, room 435
WHEN: Tuesday December 6th, 10h30 How to get to there?

Abstract:

Inclusive community engagement is paramount for fair and impartial civic decision-making. However, traditional methods rarely provide opportunities for inclusive public participation. While advances in digital civics have broadened public participation, these technologies still face several challenges in promoting inclusive participation and integrating data analysis into civic decision-making processes. In this talk, we present examples of our recent work on building and studying community-centered tools for fostering equity and inclusion in civic decision-making by (1) lowering barriers for public participation, (2) enriching data collection, and (3) facilitating more inclusive public input analysis. We describe our vision for expanding our research on democratizing civic decision-making processes and outcomes by building, deploying, and studying socially impactful technologies that integrate data visualization, social computing, and artificial intelligence.

Clemens Klokmose - Softer Software

When: Wednesday 23 November at 2pm
Where: Amphitheater of Building 660 Digiteo Moulon How to get to there?

Abstract:

Modern software is not soft at all, and it is very difficult for even the competent user to shape it to their fitting. In this talk, I will present research on how to make software softer. I'll discuss how the concept of applications has become ubiquitous and completely taken for granted in modern computing. Software doesn’t have to be synonymous with applications, and there is great potential to be unlocked if we break out of them. In this talk, I will argue for a renewed focus on developing computational media and show the efforts we have undertaken to demonstrate how software can be made differently. I will, among other things, present past and present work on the Webstrates (webstrates.net) platform.

Daniel Keefe - Designing Mixed-Reality and Tangible Data Experiences with Artists and Indigenous Communities

When: November 21st: 14:00
Where: Bat 660, Digiteo Moulin, Amphitheatre

Abstract:

As the ways we work with computers become increasingly tangible, blending the physical and digital worlds, the field of computing has an opportunity to learn from and partner with communities with deep expertise in traditional, physical ways of knowing our world. This talk will describe co-design processes, artifacts, and lessons learned from two projects that explore this potential. The first is a collaboration between technologies, visual artists, and climate scientists. The goal is to discover how skilled artists and designers working with physical art media (e.g., paint, clay, found objects) can "sculpt" accurate, data-driven climate science visualizations with an expanded visual vocabulary that has benefits for both scientific discovery and public discourse. The second is a collaboration with a community of climate and economic refugees from Micronesia who have settled in a rural town in Minnesota. Now, in a landlocked region far from their home islands, we are partnering in their efforts to maintain their culture, reviving knowledge of building and sailing canoes and the traditional celestial navigation systems that have always provided a sense of where they are and where they are going. In both projects, designing for tangible computing, including both physical inputs and physical outputs, has been the key to creating experiences that are inviting, dignity-affirming, and useful. I look forward to discussing research in the computing areas of designing user experiences, data physicalization, immersive visualization, tangible and embodied user interfaces, and mixed-reality environments through the lens of these collaborative projects that challenge us to rethink the current goals and users of computing in society.

Margret Vilborg Bjarnadottir - Introduction to People Analytics and Pay Equity: the potential role of visualizations

WHEN: Monday November 14th, 2022: 10am
WHERE: PCRI, room 435 How to get to there ?

Abstract:

As the ways we work with computers become increasingly

People analytics, the application of scientific and statistical methods to behavioral data, traces its origins to Frederick Winslow Taylor’s classic The Principles of Scientific Management in 1911, which sought to apply engineering methods to the management of people. But it was not until a century later after advances in computer power, statistical methods, and especially artificial intelligence (AI), that the field truly exploded in the power, depth, and widespread application, especially, but not only, in Human Resources (HR) management. By automating the collection and analysis of large datasets, AI and other analytics tools offer the promise of improving every phase of the HR pipeline. Algorithms are being used to help managers measure productivity and make important personnel decisions, such as hiring, compensation, promotion, and training opportunities — all of which may be life-changing for employees. Unfortunately there are many pitfalls along the way. In this talk we will highlight some of the challenges of People Analytics through examples, discuss the importance of algorithmic transparency for any HR algorithm and pose ideas about the potential role of visualizations. As time allows we will then deep dive into how algorithms and optimization can be used to support pay equity and the potential role of visualizations in the pay equity context.

Philippe Pasquier - The design and evaluation of co-creative interfaces: chalenges and opportunity of the rise of Creative AI

When: Thursday 22nd of September at 1.30PM
Where: Room 40 in the Digiteo Building 660, Université Paris Saclay

Abstract:

Creative AI is the scientific field that studies the partial or complete automation of creative tasks. Be it through the augmentation of existing creative software or through embedded real-time generation, these algorithms have a growing impact on creative practices. Now that generative algorithms have human-competitive skills for many crestive tasks, and are being deployed for professional and amateur alike, it is critical to evaluate and discuss the implications of such developments. We introduce HCI (human computer interaction) challenges and opportunities arising from these developments through a series of examples of systems developed at the Metacreation Lab and experiments conducted with these systems. We will present interfaces for computer-assisted music composition, sound design, movement computing, generative animation and moving images, and discuss their evaluation with a focus on acceptability be it by creators or their audiences.

Lonni Besançon - Science During The Pandemic: A Tale of Fast and Opaque Practices Obscurantism and Slow Corrections

When: Monday May 23rd, 10am
Where: Bat 660, amphi

Abstract:

Within months of the SARS-CoV-2 virus being identified the disease progression to COVID, viral transmission routes, and treatment options had been carefully catalogued and effective vaccines had begun development. This was one of the most impressive scientific achievements of the modern era. However, it is likely that the response to COVID-19 has succeeded in spite of rather than because of the present system for disseminating scientific outcomes. In fact, in many ways, the current dissemination system has failed us and been used during the pandemic. In this talk, I will explore, through examples in which I was involved in, how the publication system has been too opaque, too politicised, and too fast to publish yet too slow to correct. I will propose some solutions that I and other correctors have put forward recently in the hope to spark some conversations with scientists across different fields and seniority levels before diving into the threats that we face in empirical computer science and how visualization research might be able to assist.

Harpreet Sareen - Interaction Design and Non-human Behaviors

When: Wednesday May 11th, 9h-11h
Where: Telecom Paris, Amphi 4
Online talk: Link removed after the talk

Abstract:

Our practices of design have been fundamentally shaped by human behavior. However, revisiting fundamentals that shaped this human-centric context can also reshape our technological transformation from an anthropomorphic to a nature-centric view. At the cusp of technologies that can be applied much broadly to our ecology today, there is an opportunity to flatten design at the behavioral level incorporating non-human animals and organisms.

In this talk, I will discuss Interaction Design (IxD) from a vantage point of plants and animal behaviors; and creating projects with such species in various contexts. Understanding these processes may help inform our practice to design solely for non-humans and/or human/non-human relationships.

Morten Fjeld - From Tabletops to In-Motion Interaction

When: Thursday 14th Oct 2021, 10am
Where: (hybrid) Bat 660, amphi
Online talk: link removed after the event

Abstract:

The increasing abundance of data creates new opportunities for communities of interest and communities of practice. We believe that interactive tabletops will allow humans to explore data in familiar spaces such as living rooms, cafés, and public places. As part of our vision, we suggest switching from fixed tabletops to multi-device solutions. We show how multi-device solutions in the future could encourage collaboration and engage users in socially relevant data-oriented analysis . Also related to the the topic of multi-device interaction, this talk will show examples of cross-device application sharing and distributed brainstorming groupware. Addressing more recent developments, going beyond tangibles and tabletops, we will also talk about potentials for in-motion interaction.

Raimund Dachselt - Interacting with Mobile Devices for Ubiquitous Data Visualization

When: Tuesday 19th Oct 2021, 10am
Online talk: link removed after the event

Abstract:

Human beings need to be empowered to access, explore, analyze, and make sense of data and information everywhere in our data-driven world. Interactive data visualization on mobile devices has been established as one important means to support this need. In general, the past decade has seen an increasing research interest in visualization environments beyond traditional desktop computers, and visualization on mobile devices will play a prominent role in a future of diversified visualization environments.

In this talk, we will discuss the role that mobile devices can play beyond using them for single visualizations by a single person, which is currently the predominant use for, e.g., health and other personal data visualization. Based on the discussion of several own research examples, it will be shown a) how smartphones and smartwatches can be used in multi-device ensembles including large displays and multiple mobiles, b) how mobile devices can be brought closer to the body as personal visualization hubs and how new form factors can be envisioned beyond the rigid and flat high-resolution displays we are currently using, and c) how mobile devices can be combined with mixed reality technologies to allow for even more convincing, reality-based in-situ visualizations. During the talk, we will also outline research challenges associated with each of these research directions.

Carmine Elvezio - XR Development with the Relay and Responder Pattern

When: Monday July 5th, 2pm
Where: Building 650 (PCRI) room 435, Université Paris-Saclay (20 people max)
Online talk: link removed after the event


Abstract:

Augmented Reality (AR) and Virtual Reality (VR), collectively known as eXtended Reality (XR) experiences are built on rich, complex real-time interactive systems (RISs) that require the integration of numerous components supporting everything from rendering of virtual content to tracking of objects and people in the real world. Game engines such as Unity and Unreal currently provide a significantly easier pipeline than in the past to integrate different subsystems of XR applications. But there are a number of development questions that arise when considering how interaction, visualization, rendering, and application logic should interact, as developers are often left to create the “logical glue” on their own, leading to software components with low reusability. In this talk, I present a new software design pattern, the Relay & Responder (R&R) pattern, that attempts to address the concerns found with many traditional object-oriented approaches in XR systems. The R&R pattern simplifies the design of these systems by separating logical components from the communication infrastructure that connects them, while minimizing coupling and facilitating the creation of logical hierarchies that can improve XR application design and module reuse.

Additionally, I explore how this pattern can, across a number of different research development efforts, aid in the creation of powerful and rich XR RISs. I first present related work in XR system design and introduce the R&R pattern. Then I discuss how XR development can be eased by utilizing modular building blocks and present the Mercury Messaging framework (https://github.com/ColumbiaCGUI/MercuryMessaging), which implements the R&R pattern. Next I delve into three new XR systems that explore complex XR RIS designs (including user-study-management modules) using the pattern and framework. I then address the creation of multi-user, networked XR RISs using R&R and Mercury. Finally I end with a discussion on additional considerations, advantages, and limitations of the pattern and framework, in addition to prospective future work that will help improve both.

Yves Guiard - As Fast and as Accurately as Possible: Toward a Renewed Understanding of Two-Dimensional Performance Measurement in Human Behavioral Experimentation

June 15th, 14:00

Abstract:

The presentation will pretty much revolve about pointing. I will present a critique of the somewhat authoritarian ISO standard that has been ruling Fitts' law experimentation for two decades in HCI. To the extent that Fitts' law is a tool for the practical evaluation of interfaces and pointing devices, the standard has been useful. However, HCI happens to have gradually become the primary field for basic research inquiries into the general issue of pointing: from a basic research viewpoint an industrial standard has always been undesirable.

The ISO standard having made Fitts’s (1954) experimental paradigm sacrosanct, it is all the more important to try to remain lucid about the weaknesses of that paradigm. Concerning its independent variables (all about what we are supposed to do as experimenters), it is not true that the so-called "index of difficulty" (ID) controls movement difficulty: what the ID controls is the relative balance of the concurrent speed and accuracy demands; and we have the problem that the recommended factorial design for the manipulation of the ID is seriously flawed. Concerning the dependent measures (all about the performance measures we decide to consider in concertation with our participants), we have the problem that the recommended data-processing options, based on blind multiple-level averaging, are hard to reconcile with the recommended formulation of task instructions, which urge participants to try their best to minimize movement time and endpoint error.

Some alternative options will be presented regarding both the design of experiments and the definition/elaboration of performance data in a basic approach to pointing.

Jessica Hullman - Theories of Inference for Data Interactions

May 27th, 4pm CET

Abstract:

Research and development in computer science and statistics have produced increasingly sophisticated software interfaces for interactive and exploratory analysis, optimized for easy pattern finding and data exposure. But design philosophies that emphasize exploration over other phases of analysis risk confusing a need for flexibility with a conclusion that exploratory visual analysis is inherently “model free” and cannot be formalized. We describe how without a grounding in theories of human statistical inference, research in exploratory visual analysis can lead to contradictory interface objectives and representations of uncertainty that can discourage users from drawing valid inferences. We discuss how the concept of a model check in a Bayesian statistical framework unites exploratory and confirmatory analysis, and how this understanding relates to other proposed theories of graphical inference. Viewing interactive analysis as driven by model checks suggests new directions for software and empirical research around exploratory and visual analysis. For example, systems might enable specifying and explicitly comparing data to null and other reference distributions and better representations of uncertainty. Implications of Bayesian and other theories of graphical inference can be tested against outcomes of interactive analysis by people to drive theory development.

Thijs Roumen - Portable Laser Cutting

13th April 2021, 12:00 to 13:30
Online Talk: link sent through mailing list

Abstract:

A portable format for laser cutting will enable millions of users to benefit from laser-cut models as opposed to the 1000s of tech enthusiasts that engage with laser cutting today. What holds widely adopted use back is the limited ability to modify and fabricate existing models. It may seem like a portable format already exist, as laser cut models are already widely shared in the form of 2D cutting plans. However, such files are susceptible to variations in cutter properties (aka kerf) and do not allow modifying the model in any meaningful way. I consider this format machine specific.

In computing, this problem was solved in the 50s by developing compilers. This allowed developers to abstract away from the hardware and as a result, write code that remained relevant to this day. The resulting code is portable, e.g. it can be transferred from one machine to another. This transition has revolutionized not only computing but also all fields that use digital formats like desktop publishing, digital video, digital audio, etc. I believe that by transitioning towards a portable format for laser cutting we can make a similar transition from 1000s of users and one-off models towards millions of users and advanced models developed by multiple creators.

My first take on the challenge is to see how far we get by building on the de-facto standard, i.e., 2D cutting plans. I wrote software tools to modify 2D cutting plans, replacing non-portable elements with portable counterparts. This makes the models portable, but it is still hard to modify them. I thus take a more radical approach, which is to move to a 3D exchange format (kyub). This guarantees portability by generating a new machine-specific 2D cutting plan for the local machine when exported. And the models inherently allow for parametric modifications. Instead, it raises the question of compatibility: Files already exist in 2D—how to get them into 3D? I demonstrate a software tool, assembler 3 , to reconstruct the 3D geometry of the model encoded in a 2D cutting plan, allows modifying it using a 3D editor, and re-encodes it to a 2D cutting plan. I demonstrate how this approach allows me to make a much wider range of modifications, including scaling, changing material thickness, and even remixing models.

Thomas Baudel & Manon Verbockhaven - Addressing Cognitive Biases in Business Decision Support

November 16th, 14:00
Online Talk: https://ibm.webex.com/meet/baudelth

Abstract: Business process management organizes flows of information and decisions in large organizations. These systems now integrate algorithmic decision aids leveraging machine learning: each time a stakeholder needs to make a decision, such as a purchase, a quote, or hiring someone, the software can leverage the inputs and outcomes of similar past decisions to provide guidance, as a recommendation with a degree of confidence. If the confidence is high, the process may be automated. Otherwise, it may still help provide consistency in the decisions. Yet, we may question how these aids affect task performance. Can we measure an improvement? Can hidden biases influence decision makers negatively? What is the impact of various presentation options? To address those issues, we propose metrics of performance, automation bias and resistance. We validated those measures with an online study. Our aim is to provide appropriate instrumentation in those systems to secure their benefits.

Jan Gugenheimer - Ubiquitous Mixed Reality: Designing Mixed Reality Technology to Fit into the Fabric of our Daily Lives

February 18th, 14:30
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract: Technological advancements in the fields of optics, display technology and miniaturization have enabled high-quality mixed reality (AR and VR) head-mounted displays (HMDs) to be used beyond research labs. This enables a novel interaction scenario where the context of use changes drastically and HMDs aims to become a daily commodity. In this talk, I will demonstrate that the current design of HMDs does not consider the context of use (e.g. physical environment, social factors) and therefore impedes the adoption and acceptance of the technology. I will use the framework of context-aware computing to show that a parallel development happened with the transition from desktop PCs to smartphones and present several projects, highlighting how upcoming challenges of mixed reality technology could be overcome using HCI methods.

Sheelagh Carpendale - Visualization for Data Empowerment

January 20th, 14:00
Télécom Paris (Room 0B05), 19, place Marguerite Perey, 91120, Palaiseau, How to get to there?

Abstract: The importance of effectively storing, managing, and analyzing data is well understood. In my research I am interested in taking the next step – using visualization to make data humanly usable, comprehensible, and, ideally, trustable. Data visualization draws on knowledge from diverse fields such as computing science, design, cognition, perception, and graphics to create new interactive visual representations of data that are accessible, comprehensible, and explorable. In my research I hope to provide the means to glean more insight from data, and by enabling the exploration of this data, to discover answers to previously unasked questions. My goal is to empower people through use of visualizations, through the visualization of personal data, and through exploring how people can best understand the data that is increasingly part of their lives.

Lonni Besançon - Automatic Visual Censoring: from Science-Fiction to Reality

November 15th, 16:00
Sorbonne Université (Campus Jussieu), ISIR Lab (Pyramid), Room H20, How to get to there?

Abstract:

We present the first empirical study on using color manipulation and stylization to make surgery images/videos more palatable. While aversion to such material is natural, it limits many people’s ability to satisfy their curiosity, educate themselves, and make informed decisions. We selected a diverse set of image processing techniques to test them both on surgeons and lay people. While color manipulation techniques and many artistic methods were found unusable by surgeons, edge-preserving image smoothing yielded good results both for preserving information (as judged by surgeons) and reducing repulsiveness (as judged by lay people). We then conducted a second set of interview with surgeons to assess whether these methods could also be used on videos and derive good default parameters for information preservation.

Hans Gellersen - Motion coupling as interaction principle

July 9th, 14:00
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract:

Coupling of motion occurs in machines and biological systems alike, and humans are natural in coupling with external motion — for example falling in step when we walk with others, or coordinating complex tasks such as juggling. In this talk I am looking at motion coupling in user interfaces, and propose that there is a powerful principle in leveraging the correspondence of human and machine motion for interaction. I will start by discussing new forms of gaze interaction that are based on the smooth coupling of eye movement with motion stimuli at the interface. This coupling is both natural and distinct in that smooth eye movement is only observed when it has an object to follow, with fundamental implications for interface design. I will then look at bodily motion more generally, and show how motion coupling can be used to dynamically associate any form of user input for control, for example for remote pointing with the head if the hands are busy. Motion coupling challenges how we think about user interfaces and raises fundamental questions about human synchronisation and mimicry, inference of motion correspondence, and conceptual models for interaction.

Michael Sedlmair - Machine Learning meets Visualization

May 24th, 10:00
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract:

The goal of this talk is to shed light on the relation between machine learning (ML) and interactive visualization (Vis). The talk will be organized along three main parts. First, I will talk about *ML for Vis* as a way to fully or partially automatize the visualization design process. This new approach might potentially lead to a fundamental paradigm shift in visualization research and design. The second part will be on *Vis for ML*. Here, I will specifically illustrate how our approach of visual parameter space analysis can help to better understand ML models, such as dimensionality reduction, clustering, and classification models. Finally, I will argue that a close and tight integration of both *ML and Vis* will pave the way towards the future of interactive data analysis and illustrate some of the ideas with case studies.

Daniel Archambault - Drawing and Visualising Event-Based Dynamic Graphs

May 28th, 10:30
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract:

One of the most important types of data in data science is the graph or network. Networks encode relationships between entities: people in social network, genes in biological network, and many others forms of data. These networks are often dynamic and consist of a set of events -- edges/nodes with individual timestamps. In the complex network literature, these networks are often referred to as temporal networks. As an example, a post to a social media service creates an edge existing at a specific time and a series of posts is a series of such events. However, the majority of dynamic graph visualisations use the timeslice, a series of snapshots of the network at given times, as a basis for visualisation. In this talk, I present two recent approaches for event-based network visualisation: DynNoSlice and the Plaid. DynNoSlice is a method for embedding these networks directly in the 2D+t space-time cube along with methods to explore the contents of the cube. The Plaid is an interactive system for visualising long in time dynamic networks and interaction provenance through interactive timeslicing.

Ross Maciejewski - Visual Analytics in Spatiotemporal Analysis

May 14th, 14:30
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract:

From smart phones to fitness trackers to sensor enabled buildings, data is currently being collected at an unprecedented rate. Now, more than ever, data exists that can be used to gain insight into how policy decisions can impact our daily lives. For example, one can imagine using data to help predict where crime may occur next or inform decisions on police resource allocations or diet and activity patterns could be used to provide recommendations for improving an individual's overall health and well-being. Underlying all of this data are measurements with respect to space and time. However, finding relationships within datasets and accurately representing these relationships to inform policy changes is a challenging problem. This talk explores fundamental questions of how we can effectively explore such space-time data in order to enhance knowledge discovery and dissemination. I will present research that focuses on datasets from urban planning, geography, public health and crime to demonstrate our ongoing research agenda in spatiotemporal analysis.

Paul Kahn - Seeing the Differences: A New History of Information Design

March 11th, 12:00
Salle F900, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Abstract: Information design is an art practiced by every human culture in every time period. Our design heritage should not be limited to Western examples nor should our appreciation of information design be limited to the practice of data visualization. This talk will illustrate how information design encompasses the selection and encoding of both qualitative and quantitative to serve nine general functions. We will explore information design history along these functional themes: - Cosmology and Theological Narrative - World, Kingdom and City Maps - Transportation - Genealogy and Lineage - Timelines - Scientific Explanation - Economic Trends - Mechanical Controls - Engineering & Business Process We will review a collection of design solutions from different time periods and cultures in light of these themes, with special attention to Scientific Explanation. Confronting and embracing these approaches to information design will help us learning from our collective past and grow as contemporary design practitioners.

Scott Hudson - The Future is not What it Used to be: What’s Changed, What’s the Same, and What We Should Do About It

December 13th, 10:15
Amphitheater of the Digiteo Moulon Shannon building (660), How to get to there?

Abstract: A lot has changed in technology and interaction, and yet a lot has stayed the same. This talk will consider factors that have changed and not changed, and suggest ways in which the big changes should be exploited to address both old and new problems — ways in which we might be thinking differently about research challenges for interactive technology in this "new future".
