▼a Bayesian nonparametric techniques provide a rich set of tools for modeling complex probabilistic machine learning problems. However the richness comes at the cost of significant complexity of learning and inference for large scale datasets, in a |

▼a First, we develop fast inference algorithms for sequential models with Bayesian nonparametric priors using small-variance asymptotics, an emerging technique for obtaining scalable combinatorial algorithms from rich probabilistic models. We deriv |

▼a We start the second section with a novel stick-breaking definition of a certain class of Bayesian nonparametric priors called gamma processes (GP), using its characterization as a completely random measure and attendant Poisson process machinery |

▼a In the third section, we use concepts from statistical physics to develop a robust Monte Carlo sampler that efficiently traverses the parameter space. Built on the Hamiltonian Monte Carlo framework, our sampler uses a modified Nose-Poincare Hami |

▼a We continue with an L-BFGS optimization algorithm on Riemannian manifolds that uses stochastic variance reduction techniques for fast convergence with constant step sizes, without resorting to standard linesearch methods, and provide a new conve |

▼a We finish with a novel technique for learning the mass matrices in Monte Carlo samplers obtained from discretized dynamics that preserve some energy function, by using existing dynamics in the sampling step of a Monte Carlo EM framework, and lea |
