Bayesian Group Nonnegative Matrix Factorization for EEG Analysis
Bonggun Shin, Alice Oh
We propose a generative model of a group EEG analysis, based on appropriate kernel assumptions on EEG data. We derive the variational inference update rule using various approximat…
Summarizing Reviews with Variable-length Syntactic Patterns and Topic Models
Trung V. Nguyen, Alice H. Oh
We present a novel summarization framework for reviews of products and services by selecting informative and concise text segments from the reviews. Our method consists of two majo…
Dirichlet Process with Mixed Random Measures: A Nonparametric Topic Model for Labeled Data
Dongwoo Kim, Suin Kim, Alice Oh
We describe a nonparametric topic model for labeled data. The model uses a mixture of random measures (MRM) as a base distribution of the Dirichlet process (DP) of the HDP framewor…
Variable Selection for Latent Dirichlet Allocation
Dongwoo Kim, Yeonseung Chung, Alice Oh
In latent Dirichlet allocation (LDA), topics are multinomial distributions over the entire vocabulary. However, the vocabulary usually contains many words that are not relevant in…
