Parameter Selection: Why We Should Pay More Attention to It

no code implementations ACL 2021 Jie-Jyun Liu, Tsung-Han Yang, Si-An Chen, Chih-Jen Lin

In the topic of multi-label classification for medical code prediction, one influential paper conducted a proper parameter selection on a set, but when moving to a subset of frequently occurring labels, the authors used the same parameters without a separate tuning.

Efficient Optimization Methods for Extreme Similarity Learning with Nonlinear Embeddings

no code implementations26 Oct 2020 Bowen Yuan, Yu-Sheng Li, Pengrui Quan, Chih-Jen Lin

We study the problem of learning similarity by using nonlinear embedding models (e. g., neural networks) from all possible pairs.

Newton Methods for Convolutional Neural Networks

no code implementations14 Nov 2018 Chien-Chih Wang, Kent Loong Tan, Chih-Jen Lin

Deep learning involves a difficult non-convex optimization problem, which is often solved by stochastic gradient (SG) methods.

Distributed Newton Methods for Deep Neural Networks

no code implementations1 Feb 2018 Chien-Chih Wang, Kent Loong Tan, Chun-Ting Chen, Yu-Hsiang Lin, S. Sathiya Keerthi, Dhruv Mahajan, S. Sundararajan, Chih-Jen Lin

First, to reduce the communication cost, we propose a diagonalization method such that an approximate Newton direction can be obtained without communication between machines.

Dense Non-rigid Point-Matching Using Random Projections

no code implementations CVPR 2013 Raffay Hamid, Dennis Decoste, Chih-Jen Lin

We present a robust and efficient technique for matching dense sets of points undergoing non-rigid spatial transformations.

Large-Scale Video Summarization Using Web-Image Priors

no code implementations CVPR 2013 Aditya Khosla, Raffay Hamid, Chih-Jen Lin, Neel Sundaresan

A Bayesian Approximation Method for Online Ranking

4 code implementations Journal of Machine Learning Research 2011 Ruby C. Weng, Chih-Jen Lin

Experiments on game data show that the accuracy of our approach is competitive with state of the art systems such as TrueSkill, but the running time as well as the code is much shorter.
