Semi-Supervised Learning on Data Streams via Temporal Label Propagation

no code implementations ICML 2018 Tal Wagner, Sudipto Guha, Shiva Kasiviswanathan, Nina Mishra

We consider the problem of labeling points on a fast-moving data stream when only a small number of labeled examples are available.

In this paper we focus on the anomaly detection problem for dynamic data streams through the lens of random cut forests.

Anomaly Detection

Approximation Algorithms for Bayesian Multi-Armed Bandit Problems

no code implementations14 Jun 2013 Sudipto Guha, Kamesh Munagala

We show that by restricting the state spaces of arms we can find single arm policies and that these single arm policies can be combined into global (near) index policies where the approximate version of the exchange property is true in expectation.
