报告题目:Metric learning with Lipschitz continuous functions

时间:1月9日下午16:00-17:15

地点:计算所446会议室


报告摘要:

Metric learning enables classification algorithms to automatically learn a suitable distance metric from data, such that semantically similar instances are pulled together while dissimilar instances are pushed away. A learned metric can significantly improve the performance of distance-based classifiers (e.g. kNN). In this talk, I will briefly present some of our recent research efforts on metric learning with Lipschitz continuous functions, including the methodology, theoretical foundation and optimisation formulation of each work. A brief introduction to University College London (UCL) will also be given.
