lessAbstract: A central phenomenon in modern machine learning is feature learning: rather than operating on a fixed representation of the data, successful models learn representations adapted to the prediction task. We study a tractable model of this phenomenon through a compositional variant of kernel ridge regression, where the kernel is applied after a learnable linear transformation. When the response depends on the input only through a low-dimensional predictive subspace, we show that optimizing the population objective automatically eliminates directions orthogonal to this subspace and, in certain regimes, exactly recovers it. Surprisingly, the same exact low-dimensional structure persists at finite sample sizes with high probability, even without explicitly penalizing the linear transformation to be low-dimensional.
Bio: Feng Ruan is currently an assistant professor in Department of Statistics and Data Science at Northwestern University. His research focuses on the foundations of feature learning and stochastic and nonsmooth optimization, and is supported by an NSF CAREER Award.

lessAbstract: We consider stochastic and finite-sum optimization problems with deterministic constraints. Existing methods typically focus on finding an approximate stochastic solution that ensures the expected constraint violations and optimality conditions meet a prescribed accuracy. However, such an approximate solution can potentially lead to significant constraint violations. To address this issue, we propose variance-reduced first-order methods that treat the objective and constraints differently. Under suitable assumptions, our proposed methods achieve stronger approximate stochastic solutions with complexity guarantees that more reliably satisfy the constraints compared to existing methods. This is joint work with Sanyou Mei (HKUST) and Yifeng Xiao (UMN).

lessBio: Zhenyu "James" Kong is the Ralph H. Bogle Jr. Professor in the Grado Department of Industrial and Systems Engineering at Virginia Tech. He received his BS and MS in Mechanical Engineering from the Harbin Institute of Technology and his PhD in Industrial and Systems Engineering from the University of Wisconsin-Madison in 2004. His research focuses on sensing and analytics for smart manufacturing, modeling and diagnosis of large and complex manufacturing systems, and machine learning for manufacturing applications, and he is a Fellow of the Institute of Industrial and Systems Engineers.This talk consists of two parts. In the first part, we study the inference reliability of large language models (LLMs), with an emphasis on characterizing how prompt design affects the accuracy and stability of model outputs. We discuss recent theoretical and empirical advances in in-context learning and hallucination, and examine conditions under which LLMs produce reliable predictions. In the second part, we consider constrained bilevel optimization and develop efficient algorithms with provable guarantees. In particular, we show how error bound conditions can be leveraged to obtain fast convergence rates under mild assumptions.
