Efficient active learning of sparse halfspaces

Chicheng Zhang

We study the problem of efficient PAC active learning of homogeneous linear classifiers (halfspaces) in $R^{d}$ , where the goal is to learn a halfspace with low error using…

Spectral Learning of Binomial HMMs for DNA Methylation Data

Chicheng Zhang, Eran A. Mukamel, Kamalika Chaudhuri

We consider learning parameters of Binomial Hidden Markov Models, which may be used to model DNA methylation data. The standard algorithm for the problem is EM, which is computatio…
