Corpus and Topic Scalable Topic Model
Soma Yokoi, Issei Sato, Hiroshi Nakagawa (UTokyo) IBISML2015-5
Abstract (in Japanese) (See Japanese page) 
(in English) It is known that topic model with high dimensional topics improves IR performance like search engines and online advertisements, because it helps to model long-tail words in large scale corpora. However, high dimensional topics with large corpora cause 2 problems: computational performance and memory requirement. For the fundamental topic model, LDA, SGRLD LDA is proposed to scale to large corpora and AliasLDA to accelerate computing topics. In this paper, we propose a method for both topic computation and data scalability, by combining these techniques. Also careful calculation of gradients reduces required space to expectations. Experiments demonstrate that our method is scalable for both corpus size and topic dimension, also achieve faster runtime speed compared to the existing approach, especially 10+ times faster on high dimensional topics setting.
