A Minimax Probability Machine for Non-Decomposable Performance Measures
Junru Luo, Hong Qiao, Bo Zhang
Imbalanced classification tasks are widespread in many real-world applications. For such classification tasks, in comparison with the accuracy rate, it is usually much more appropr…
Learning with Smooth Hinge Losses
JunRu Luo, Hong Qiao, Bo Zhang
Due to the non-smoothness of the Hinge loss in SVM, it is difficult to obtain a faster convergence rate with modern optimization algorithms. In this paper, we introduce two smooth…
Effective Deterministic Initialization for -Means-Like Methods via Local Density Peaks Searching
Fengfu Li, Hong Qiao, Bo Zhang
The -means clustering algorithm is popular but has the following main drawbacks: 1) the number of clusters, , needs to be provided by the user in advance, 2) it can easily re…
Isometric Multi-Manifolds Learning
Mingyu Fan, Hong Qiao, Bo Zhang
Isometric feature mapping (Isomap) is a promising manifold learning method. However, Isomap fails to work on data which distribute on clusters in a single manifold or manifolds. Ma…
