Imperceptible Textile Interfaces
December 2nd, 2020, 3:30 pm CET
In the last fifteen years, we have witnessed a dramatic trans formation of our society through the miniaturization of computing technologies. This introduced a new age in which people can access the power of computing devices on-demand, just by reaching into their pockets. While such electronics can be helpful in numerous situations, these technologies alone have limited reach and impact. With “Imperceptible Textile Interfaces”, our vision is to embed intelligence into the ubiquitous medium of textiles, thereby ushering in a new era in which everyday objects and even the very clothes we wear can play an unobtrusive yet always-accessible and powerful role in enhancing our experience of all aspects of our lives ranging from transportation and communication to work and play. In this talk, we will present a novel sensing approach enabling a new kind of yarn-based, resistive pressure sensing.

Human Interaction and Collaboration with Machine Learning Models
November 10th, 2:00 pm CET
Room: Youtube Live Stream
With the increasing adoption of machine learning models across domains, we have to think about the human role when interacting with these models. In the last years, my collaborators and I have created a series of tools that utilize visualization and visual user interaction to help investigate behavior of machine learning models (for NLP and CV). I will present a selection of these scientific tools that makes humans play and then understand.
About the Speaker:
Hendrik Strobelt is the Explainability Lead at the MIT-IBM Watson AI Lab and Research Scientist at IBM Research. His recent research is on visualization for and human collaboration with AI models to foster explainability and intuition. The majority of his work is for NLP models and generative models while he is advocating to utilize a mix of data modalities to solve real-world problems. His work is applied to tasks in machine learning, in NLP, in the biomedical domain, and chemistry. Hendrik joined IBM in 2017 after postdoctoral positions at Harvard SEAS and NYU Tandon. He received a Ph.D. (Dr. rer. nat.) from the University of Konstanz in computer science (Visualization) and holds an MSc (Diplom) in computer science from TU Dresden. He received multiple best paper/honorable mention awards at EuroVis, BioVis, VAST, and ACL Demo. He received the Lohrmann medal from TU Dresden as the highest student honor. Hendrik has served in program committees and organization committees for IEEE VIS, BioVis, EuroVis. He was the virtual chair for ICLR 2020, AIstats 2020, and Online Experience Chair for NeurIPS 2020. Hendrik is affiliated as visiting researcher with MIT CSAIL.

Recent advances in water wave animation
October 21st, 2020, 4:00 pm CEST
This talk will give an overview of our group's recent progress in water wave animation. Existing methods for solving wave equations (like finite elements, finite differences, and spectral/Fourier methods) tend to fall short of the level of detail required for visual effects, or they fail to convincingly animate interactions with boundaries (like a wave reflecting off a rock).
Over the past few years, our group has experimented with new ways to animate water waves, including boundary integrals, wave packets and wavelets, and analytic solutions of the Navier-Stokes equations, and even simple geometric heuristics. During this talk, I will explain the problem and give an overview of our various methods and results.
The talk describes research collaborations with the following co-authors:

AI and computer vision for autonomous drones and robots
January 28th, 2020, 3:00 pm CET
Room: Science Park Building 3, Room 063
Drones are small scale flying robots and it is predicted that the drone market as well as the general robotics market will see a major growth in the near future. AI and computer vision will play a major role in shaping the future autonomous drones. In my talk I will give an overview of the use of AI and computer vision techniques in robotics and for drones in particular. I will then follow up by presenting developments in this area done in my lab, which will include the topics of 3D mapping, localization, path planning and environment interpretation.
