m-SNE: Multiview Stochastic Neighbor Embedding

2

Outlines

MotivationObjectivesMethodologyExperimentsConclusionsComments

3

Motivation• To duly utilize different features or multiview data is a

challenge

Conventional strategies

Different statistical properties are not considered

Different features are not well explored

Corrupting by noise

Objectives

4

• To propose a multiview stochastic neighbor embedding to unify different features under a probabilistic framework.

Methodology - Framework

Methodology – m-SNE

Methodology – Accelerated First-Order Method for Combination Coefficient

• Lipschitz continuous

• First order function

• Second order function

Conclusions• m-SNE is able to meaningfully integrates different

views.• The combination coefficient can – exploit complementary information in different

view– suppress noise

13

Comments• Advantages– m-SNE can integrate different views

• Applications– Dimension reduction, image retrieval and

multiview learning
