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.
m-SNE

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
