Elchanan Mossel: Corruption Detection and Shotgun Assembly of Networks Tuesday, November 3, 2015 - 4:00pm to 5:00pm Abstract: I will discuss two algorithmic problems on networks. The first problem is the classical and well studied problem of identifying faulty nodes in a network given reports of their neighbors. |

Nati Linial: High-Dimensional Permutations Tuesday, November 24, 2015 - 4:00pm to 5:00pm Abstract: This talk starts from the realization that many of the basic combinatorial constructs that we use all the time are inherently one dimensional. Permutations are a case in point. |

Sanjeev Arora: The linear algebraic structure of word meanings Tuesday, September 15, 2015 - 4:15pm to 5:15pm Abstract: In Natural Language Processing (NLP), semantic word embeddings are used to capture the meanings of words as vectors. They are often constructed using nonlinear/nonconvex techniques such as deep nets and energy-based models. |

Ravi Kannan: Topic Modeling and NMF using Soft Clustering Tuesday, September 22, 2015 - 4:15pm to 5:15pm Abstract: The model fitting problem in Topic Modeling is a special case of Non-Negative Matrix Factorization and both are computationally hard. Soft clustering, where, each datapoint can belong fractionally |
