A Forward-Backward Approach for Visualizing Information Flow in Deep Networks

2017 · arXiv (Cornell University)

We introduce a new, systematic framework for visualizing information flow in deep networks. Specifically, given any trained deep convolutional network model and a given test image, our method produces a compact support in the image …

Query Efficient Structured Matrix Learning

2025 · arXiv (Cornell University)

We study the problem of learning a structured approximation (low-rank, sparse, banded, etc.) to an unknown matrix $A$ given access to matrix-vector product (matvec) queries of the form $x \rightarrow Ax$ and $x \rightarrow A^Tx$. …
