Optimizing importance weighting in the presence of sub-population shifts

ICLR 2025poster

A distribution shift between the training and test data can severely harm performance of machine learning models. Importance weighting addresses this issue by assigning different weights to data points during training. We argue that existing heuristics for determining the weights are suboptimal, as…

Removing Spurious Concepts from Neural Network Representations via Joint Subspace Estimation

ICML 2024poster

An important challenge in the field of interpretable machine learning is to ensure that deep neural networks (DNNs) use the correct or desirable input features in performing their tasks. Concept-removal methods aim to do this by eliminating concepts that are spuriously correlated with the main task…
