Extreme Bandits using Robust Statistics
Sujay Bhatt, Ping Li, Gennady Samorodnitsky
We consider a multi-armed bandit problem motivated by situations where only the extreme values, as opposed to expected values in the classical bandit setting, are of interest. We p…
Non-Local Feature Aggregation on Graphs via Latent Fixed Data Structures
Mostafa Rahmani, Rasoul Shafipour, Ping Li
In contrast to image/text data whose order can be used to perform non-local feature aggregation in a straightforward way using the pooling layers, graphs lack the tensor representa…
Provable Data Clustering via Innovation Search
Weiwei Li, Mostafa Rahmani, Ping Li
This paper studies the subspace clustering problem in which data points collected from high-dimensional ambient space lie in a union of linear subspaces. Subspace clustering become…
Closed-Form, Provable, and Robust PCA via Leverage Statistics and Innovation Search
Mostafa Rahmani, Ping Li
The idea of Innovation Search, which was initially proposed for data clustering, was recently used for outlier detection. In the application of Innovation Search for outlier detect…
