Escaping the Curse of Dimensionality in Similarity Learning: Efficient Frank-Wolfe Algorithm and Generalization Bounds

1 code implementation20 Jul 2018 Kuan Liu, Aurélien Bellet

Our experiments on datasets with up to one million features demonstrate the ability of our approach to generalize well despite the high dimensionality as well as its superiority compared to several competing methods.

A Batch Learning Framework for Scalable Personalized Ranking

1 code implementation10 Nov 2017 Kuan Liu, Prem Natarajan

In designing personalized ranking algorithms, it is desirable to encourage a high precision at the top of the ranked list.

WMRB: Learning to Rank in a Scalable Batch Training Approach

no code implementations10 Nov 2017 Kuan Liu, Prem Natarajan

We propose a new learning to rank algorithm, named Weighted Margin-Rank Batch loss (WMRB), to extend the popular Weighted Approximate-Rank Pairwise loss (WARP).

Kernel Approximation Methods for Speech Recognition

no code implementations13 Jan 2017 Avner May, Alireza Bagheri Garakani, Zhiyun Lu, Dong Guo, Kuan Liu, Aurélien Bellet, Linxi Fan, Michael Collins, Daniel Hsu, Brian Kingsbury, Michael Picheny, Fei Sha

First, in order to reduce the number of random features required by kernel models, we propose a simple but effective method for feature selection.

Similarity Component Analysis

no code implementations NeurIPS 2013 Soravit Changpinyo, Kuan Liu, Fei Sha

Moreover, we show how SCA can be instrumental in exploratory analysis of data, where we gain insights about the data by examining patterns hidden in its latent components' local similarity values.
