报告摘要:

1) Title: Monitoring of BD3 -- Big, Dynamic, Distributed Data

In this talk, I will survey algorithms to monitor BD3, which attempt to reduce communication and computational complexity. The proposed approach relies on geometric considerations which are quite intuitive to grasp.

2) Title: Big Data Classification Using a Background Prior

A canonical problem in machine learning is category classification (e.g. find all instances of human faces, cars etc., in an image). In this talk I will describe an efficient and easy to apply classification algorithm, which replaces the negative samples by a prior and then constructs a "hybrid" classifier that separates the positive samples from this prior. The resulting classifier achieves an identical or better classification rate than SVM, while requiring far smaller memory and lower computational complexity to train and apply.
