Kernelized Parameter Sensitivity Atlases for Amortized Conditional Interpretability
Davide Wiest, Ahanaf Hasan Ariq, Abdul Monaf Chowdhury
Gradient-based attribution provides input-specific information about model parameters, but computing it via backpropagation for many samples is expensive, while static importance s…

Pseudospectral Bounds for Transient Amplification in Coupled Gradient Descent
Ahanaf Hasan Ariq
Coupled gradient descent - where the update of one parameter depends on another - arises naturally in bilevel optimization, two-time-scale stochastic approximation, and generative…

Certifying Whether to Adapt: Baseline-Relative PAC-Bayes-MMD Guarantees for Test-Time Adaptation
Ahanaf Hasan Ariq, Hasaan Ahmad, Aayush Parekh +1
Test-time adaptation (TTA) needs a decision about an update, not only an absolute-risk estimate. We give PAC-Bayesian certificates for the target excess risk of a candidate relativ…
