報告:Ranking Preserving Nonnegative Matrix Factorization

報告人:王晶(日本東京大學博士后)

報告內容:Nonnegative matrix factorization (NMF), a well-known technique to find parts-based representations of nonnegative data, has been widely studied. In reality, ordinal relations often exist among data,such as dataiis more related tojthan toq. Such relative order is naturally available, and more importantly, it truly reflects the latent data structure. Preserving the ordinal relations enables us to find structured representations of data that are faithful to the relative order, so that the learned representations become more discriminative. However, this cannot be achieved by current NMFs. In thispresentation,Dr. Wangmake the attempt towards incorporating the ordinal relations and propose a novel ranking preserving nonnegative matrix factorization (RPNMF) approach, which enforces the learned representations to be ranked according to the relations.Shederive iterative updating rules to solve RPNMF’s objective function with convergence guaranteed. Experimental results with several datasets for clustering and classification have demonstrated that RPNMF achieves greater performance against the state-of-the-arts, not only in terms of accuracy, but also interpretation of orderly data structure.

報告:Brief talk about VRandAR

報告人:馬弘霖(麻省理工大學博士丰彩彩票app官方下载丰彩彩票app官方下载,現任蘋果公司高級工程師)

報告內容:In recent years丰彩彩票app官方下载,VR technology develop rapidly.The virtual realityis widely used in our daily life.Dr. Mawillintroduce how VR technology can change people's daily lives, especially in education, medical care, tourism, and others insights that have changed which could influenced us. And how we develop our own VR hardware software products. Similarly, we use VR an technologies together to develop new technology products that change traditional industries.

報告:Hyperbolic Space for Hierarchical Data Embedding

報告人:Atsushi Suzuki(日本東京大學博士生)

報告內容:Embedding refers to a map from a object set to a space, with additional information preserved. Here, additional information includes an edge set in graph embedding setting and a distance matrix in metric multi-dimensional scaling. Although existing approaches have preserved such additional information in Euclidean space, whether Euclidean space is compatible with true data structure is largely ignored. which is essential to effective embedding. Since real data often exhibit hierarchical structure, it is hard for Euclidean space approaches to achieve effective embeddings in low dimensionality, which incurs high computational complexity or overfitting. Recent work has solved this problem by using hyperbolic space. In presentation,Mr. Suzukibriefly explain some basic properties of hyperbolic space, and how hyperbolic space works on embedding of hierarchical data.
