A Spectral View of Adversarially Robust Features
Shivam Garg, Vatsal Sharan, Brian Hu Zhang +1
Given the apparent difficulty of learning models that are robust to adversarial perturbations, we propose tackling the simpler problem of developing adversarially robust features.…
Recovery Guarantees for Quadratic Tensors with Sparse Observations
Hongyang R. Zhang, Vatsal Sharan, Moses Charikar +1
We consider the tensor completion problem of predicting the missing entries of a tensor. The commonly used CP model has a triple product form, but an alternate family of quadratic…
Efficient Anomaly Detection via Matrix Sketching
Vatsal Sharan, Parikshit Gopalan, Udi Wieder
We consider the problem of finding anomalies in high-dimensional data using popular PCA based anomaly scores. The naive algorithms for computing these scores explicitly compute the…
