Let Me Grok for You: Accelerating Grokking via Embedding Transfer from a Weaker Model

ICLR 2025poster

''Grokking'' is a phenomenon where a neural network first memorizes training data and generalizes poorly, but then suddenly transitions to near-perfect generalization after prolonged training. While intriguing, this delayed generalization phenomenon compromises predictability and efficiency. Ideally…

Secure On-Device Video OOD Detection Without Backpropagation

ICCV 2025poster

Out-of-Distribution (OOD) detection is critical for ensuring the reliability of machine learning models in safety-critical applications such as autonomous driving and medical diagnosis. While deploying personalized OOD detection directly on edge devices is desirable, it remains challenging due to la…

Analyzing Adversarial Vulnerabilities of Graph Lottery Tickets

ICASSP 2024accepted

Graph neural networks (GNNs) have displayed significant potential in various graph-based learning tasks. However, the computational demands of deploying GNNs on large-scale graphs can grow exponentially. A recent method, termed unified graph sparsification (UGS), shows that there exists a pair consi…
