Title: Low-rank Tensor Decompositions for Count Data


Abstract: Low-rank tensor decompositions are useful in many data science tasks, such as data compression, noise reduction, pattern extraction, and data imputation. In many applications, the data consists of integers representing count values. In this talk, I will present an introduction to low-rank tensor decomposition, some of the challenges of working with tensor count data when computing decompositions, and how we can address these challenges in practice. Furthermore, I will describe several recent advances associated with low-rank decompositions of tensor count data, including topics on data modeling, computation, error analysis, and regression modeling.
