Low-rank matrix completion is a well-studied problem, for which a rich theory exists, mainly from the optimization and statistical points of view. However, the majority of the theoretical analysis in the literature assumes random observation patterns. On the other hand, the pattern of observed entries depends on the nature of each application, and is usually […]
Contact interactions, including adhesion and friction, are critical to the design of many engineered systems. Currently, most systems rely on materials with static mechanical properties, requiring careful selection of materials to realize effective systems for specialized tasks. However, with advances in smart materials, system design is no longer limited to materials with static properties. There […]
*This seminar will be held in-person in Levine 307 as well as virtually via Zoom. ABSTRACT To make a future where robots are helpful and commonplace, robots must physically interact with humans and their surroundings. In this talk, I argue that robots should be designed from a materials-centric approach to better facilitate these interactions. If […]
If learning from data is valuable, can learning from big data be very valuable? It has been, so far, in vision and language, for which foundation models can be trained on web-scale data to support a plethora of downstream tasks; not so much in control, for which scalable learning remains elusive. Can information encoded in […]
Cyber-physical systems often include communication networks that ensure data transmission between different components of the system (sensors, actuators, processing units, etc). The presence of such networks renders the whole system vulnerable to malicious attacks consisting, for example, in the injection of arbitrary signals. In this context, the data collected over the communication channel may be […]
In this talk, I will focus on two challenging imaging systems: snapshot compressive imaging and coherent imaging under speckle noise interference. I will begin by reviewing the core mathematical modeling of the inverse problem corresponding to each system. I will develop a maximum likelihood estimator (MLE)-based optimization for each, employing untrained neural networks (NNs) to […]
*This seminar will be held in-person in Levine 307 as well as virtually via Zoom. ABSTRACT In this keynote, I will talk about our latest research on creating photo-realistic AI Avatars. Here, our main goal is to create virtual characters that can are visually indistinguishable from photos and videos of real people. Further, we aim […]
*This seminar will be held in-person in Levine 307 as well as virtually via Zoom. ABSTRACT Understanding the 3D structure of real-world environments is a fundamental challenge in machine perception, critical for applications spanning robotic navigation, content creation, and mixed reality scenarios. In recent years, machine learning has undergone rapid advancements; however, in the 3D […]
Legged robots, robotic manipulators, and their combined embodiment as humanoid robots have received considerable attention across both academia and industry. However, with few notable exceptions, state-of-the-art demonstrations are significantly less dynamic than their biological counterparts. A considerable challenge for performing more dynamic tasks for both legged robots and robotics manipulators lies within controlling contact interactions […]
The field of robotic manipulation is attempting to expand from structured warehouse and lab environments to in-the-wild applications in human-centric settings. When deployed in novel settings, a robot may see and need to interact with a new object for the first time. Model-based control approaches rely on a priori dynamics models, an assumption that does […]
Ferroelectric properties were initially discovered in perovskite-structured materials over a century ago. However, it was only in the last two decades that these properties were confirmed in fluorite-structured doped HfO2 and wurtzite-structured AlN films, respectively. The ferroelectricity in doped HfO2 or ZrO2 has been attributed to a previously unknown non-centrosymmetric orthorhombic Pca21 phase, while it […]
This seminar will be held in-person in Wu and Chen as well as virtually via Zoom. ABSTRACT Since its inception, Robotics has constantly used technological developments to address new customer needs. These developments have occurred in two areas: mechatronics and software & control. Mechatronic advances made robots stronger, faster, and more accurate. In parallel, software […]
