A spectral algorithm for learning mixture models
A mixture model is a weighted combination of probability distributions. We consider the problem of identifying the component distributions of a mixture model by examining random samples from the mixture. Our main result is that a simple spectral algorithm for learning a mixture of k spherical Gaussians in n-dimensions works remarkably well — it succeeds in identifying the Gaussians assuming ess...
متن کاملA Hybrid Optimization Algorithm for Learning Deep Models
Deep learning is one of the subsets of machine learning that is widely used in Artificial Intelligence (AI) field such as natural language processing and machine vision. The learning algorithms require optimization in multiple aspects. Generally, model-based inferences need to solve an optimized problem. In deep learning, the most important problem that can be solved by optimization is neural n...

متن کاملA Spectral Algorithm for Learning Hidden Markov Models
Hidden Markov Models (HMMs) are one of the most fundamental and widely used statistical tools for modeling discrete time series. Typically, they are learned using search heuristics (such as the Baum-Welch / EM algorithm), which suffer from the usual local optima issues. While in general these models are known to be hard to learn with samples from the underlying distribution, we provide the firs...
متن کاملSpectral Learning of Mixture of Hidden Markov Models
In this paper, we propose a learning approach for the Mixture of Hidden Markov Models (MHMM) based on the Method of Moments (MoM). Computational advantages of MoM make MHMM learning amenable for large data sets. It is not possible to directly learn an MHMM with existing learning approaches, mainly due to a permutation ambiguity in the estimation process. We show that it is possible to resolve t...
