CIS Seminar: “Privacy-Preserving Accountability Online”

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

Technologies that enable confidential communication and anonymous authentication are important for improving privacy for users of internet services. Unfortunately, encryption and anonymity, while good for privacy, make it hard to hold bad actors accountable for misbehavior. Internet services rely on seeing message content to detect spam and other harmful content; services must also be able […]

ASSET Seminar: Statistical and Machine Learning for Electronic Health Records: Challenges and Opportunities, Qi Long (University of Pennsylvania)

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

ABSTRACT: Electronic health records (EHRs) offer great promises in advancing clinical research and transforming learning health systems. However, complex, temporal EHRs are fraught with biases and present daunting analytical challenges that, if not addressed, can exacerbate health inequities. EHRs data, recorded at irregular time intervals with varying frequencies, are multi-modal and multi-scale including structured data […]

Spring 2023 GRASP SFI: Edward Hu, University of Pennsylvania, “Focusing on Task-Relevant Information in RL for Robots”

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. This week's presenter will be in-person as well. ABSTRACT While it is tempting to view robotics as a nail that can be solved with the deep learning hammer, we have seen that deep-learning based perception and action pipelines for […]

CBE Seminar Series: “Decisions through Oscillation: Learning from Endothelial Cells” (Andre Levchenko, Yale University)

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

Abstract: Blood vessels constitute one of the most complex and most essential biological systems, sometimes referred to as a separate organ. Endothelial cells, lining blood vessels are also one of the most 'plastic' cell types, capable of a wide range of responses to external stimuli, conditioned on their internal states and micro-environment. Strikingly, many of […]

MEAM Seminar: “Control of Jump Stochastic Systems by Learning Recurrent Spatiotemporal Patterns”

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

Efficient learning for stochastic control and estimation remains a topic of high interest in a variety of disciplines and there are well-known advantages and disadvantages to both model-free and model-based learning. On one hand, it is becoming increasingly more feasible to rely entirely on model-free/data-driven methods for controlling complex stochastic systems, but a well-known issue […]

MSE Seminar: “Fundamental Understanding of Mechanical Properties and Deformation Mechanisms of Emerging Complex Alloys Serving under Extreme Conditions” (Lawrence Berkeley National Laboratory)

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

The development of stronger and tougher materials serving under extreme conditions is a long-term goal of materials research that has been made even more urgent recently by our quests for space exploration and energy sustainability. Recently, the advent of alloys with increased complexity, e.g., multi-principal element alloys (MPEAs), additively manufactured (AM) alloys, and alloys with […]

ESE Spring Seminar – “Scalable Data-Driven Decision-Making for Smart Autonomous Power and Energy Systems”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Rapidly growing renewable generations and peak loads pose a serious threat to the security and reliability of modern power and energy systems. A critical question is "how to accommodate a high penetration of renewable generation and deep electrification?". This talk focuses on two key challenges, i.e., unknown information and the scalability issue of coordinating large-scale […]

CNT/PHT Seminar: “The Future of Brain Interfacing” (Philip Sabes, Neuralink, UCSF)

Rubenstein Audtorium, Smilow Center for Translational Research

"The Future of Brain Interfacing" Brain interfacing holds immense promise, both for restoring lost sensory, motor or cognitive function and for the treatment of neurological and neuropsychiatric disorders. The promise is driving a great deal of interest in brain interfacing technologies -- from researchers, industry, investors, and the public -- yet the clinical impact of […]

BE Seminar: “Building Tissues: Engineering Complexity Through Biomaterial Design” (Brendan Harley, University of Illinois)

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

Advances in the fields of tissue engineering and regenerative medicine require biomaterials that instruct, rather than simply permit, a desired cellular response. A major challenge to progress in our field is the complex organization of the tissues in our bodies, which are hierarchical, vary in space and time, and can differ person-to person. Prof. Harley’s […]

CIS Seminar: ” Foundations of Responsible Machine Learning”

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

Algorithms make predictions about people constantly.  The spread of such prediction systems has raised concerns that machine learning algorithms may exhibit problematic behavior, especially against individuals from marginalized groups.  This talk will provide an overview of my research building a theory of "responsible" machine learning.  I will highlight a notion of fairness in prediction, called […]
