Fall 2022 GRASP Seminar: Tomas Pajdla, Czech Technical University, “Solving Minimal Problems in the Age of Machine Learning”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom.   ABSTRACT I will discuss several our recent advances in understanding minimal problems in computer vision using numerical algebraic geometry tools, i.e., Homotopy continuation and monodromy, as well as machine learning. I will talk about our classification of minimal […]

MEAM Seminar: “Materials and Manufacturing Solutions for Sustainable Energy”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

In response to the grave and escalating threat of climate change, the US Department of Energy has announced a series of ambitious Energy Earth Shot Initiatives. These target an 80% reduction in the cost of clean hydrogen by 2030 and net-zero carbon emissions by 2050. The first of the initiatives focuses on establishing a green […]

LRSM Special Lecture: “Pursuing a Scientific Career at a National Laboratory”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

If you are finishing your PhD or your postdoctoral tenure you may be asking yourself, What’s next? Should I pursue an academic career, as my thesis adviser or postdoctoral supervisor has done? Or should I look elsewhere, perhaps at industry, or government? These are great questions that most of us have asked ourselves at the […]

BE Seminar: “Studying the Neural basis of Natural Spatial, Social and Acoustic Behaviors – in Freely Behaving and Flying Bats” (Michael Yartsev, UC Berkeley)

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

This is a hybrid seminar that will take place in Glandt Forum (Singh Center) and via Zoom (check email for link and passcode). Our lab seeks to understand the neural basis of complex spatial, acoustic and social behaviors in mammals. To do so, we take a neuroethological approach that leverages the specialization of the bat […]

ASSET Seminar: What Transfers in Transfer Learning?, Eric Wong (University of Pennsylvania)

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

Abstract: Recently, the transfer learning paradigm has seen a surge of interest due to its impressive capabilities in vision and language. Models are pretrained on ever-growing datasets with enormous parameter counts, trending towards being monolithic and opaque. How can we understand the underlying process? This talk will provide, to some degree, insight on how data […]

Fall 2022 GRASP SFI: Sonia Chernova, Georgia Institute of Technology, “Semantic-Driven Robot Assistance and User Interaction”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Reliable operation in everyday human environments – homes, offices, and businesses – remains elusive for today’s robotic systems.  A key challenge is diversity, as no two homes or businesses are exactly alike.  However, despite the innumerable unique aspects […]

MSE Seminar: “Additive Manufacturing of Compositionally Complex Alloys with Engineered Microstructures”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

The increasing demand for structural metals has driven increasingly complex compositions, which bring critical challenges in processing of these materials. Additive manufacturing, also called 3D printing, is a disruptive technology for creating structural materials and components in a single print. In this talk, I will present our recent work on additive manufacturing of compositionally complex […]

MEAM Seminar: “Exergy-based Methods as a Promising Modern Thermodynamic Evaluation and Optimization Tool”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Exergy-based methods are powerful tools for developing, evaluating, understanding, and improving energy conversion systems. In addition to conventional methods, advanced exergy-based analyses consider (a) the interactions among components of the overall system, and (b) the real potential for improving each important system component. The main role of an advanced analysis is to provide energy conversion […]
