摘要: In the classic statistical inference problems, all data is available at a centralized location. With the explosion of the size of data set, it is increasingly common that data is stored in multiple terminals connected by links with a limited communication capacity. In this scenario, terminals have to exchange compressed data and perform statistical inference using the compressed data. In this talk, we will discuss our recent work that addressed the following two questions: 1) Suppose we would like to achieve the same optimal inference as that of the centralized case, how much data compression can be performed? and 2) Suppose we compress the data extremely (zero-rate compression), what is the optimal inference performance?
