This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Tactile and visual perception are crucial for fine-grained human interactions with the environment. […]
From knotted cords to contemporary computers, the revolution in information technologies has been a major driving force of human civilization. Since its emergence in the early 1900s, quantum mechanics has […]
Zoom link: https://upenn.zoom.us/j/98220304722 Modern LLMs process information by repeatedly applying a basic primitive of matrix multiplication. Estimates show that about 60-84% of the energy consumed by LLMs goes into […]
This event will be in-person ONLY in Wu and Chen Auditorium. ABSTRACT Autonomous agents need a world model that explains observations, predicts what comes next, and chooses actions over long […]
Surface electrochemical actuators (SEAs) harness ion-induced surface stress changes to produce large bending deformations at the microscale. They have previously been applied in microrobot locomotion and microbattery validation, demonstrating their […]
Understanding the physical processes modulating the transport of scalars, such as heat, over very rough surfaces is essential for understanding the thermal environment of cities, how wind and solar farms […]
There has been considerable interest in the colloidal self-assembly of photonic crystals with a diamond structure, owing to their exceptional optical properties, such as a wide photonic bandgap and relative […]
Abstract: Liquid–liquid phase separation is a fundamental thermodynamic process that governs structure and function in biological systems, chemical separations, and multiphase materials. Within this broad field, computational studies play a […]
Large language models (LLMs) are powerful but not yet reliable: they hallucinate, misalign with human values, and struggle with social reasoning. In this talk, I will trace a path from […]
