题目:  Similarity-preserved Hashing: Diffusing from Images Retrieval to Other Scenarios

报告时间：2021年11月25日9:00—11:00

报告地点：信息大厦B1111

Abstract:In the past decade, we have witnessed an explosive growth of data on the Internet, and it brings both challenges and opportunities to traditional algorithms developed on small to median scale data sets. Particularly, nearest neighbor search (NN) has become a key ingredient in many large-scale machine learning and data management tasks. In fact, approximate nearest neighbors (ANN) are enough to achieve satisfactory performance in many applications, such as the image retrieval task in search engines. Due to the low storage cost and fast retrieval speed, similarity-preserved hashing is one of the popular solutions for ANN search. This talk will first review related methods for images, then introduce the ways how similarity-preserved hashing is enabling natural language processing. It will also highlight open problems that are being addressed by emerging research.
