Graph-based Entropy for Detecting Precursors of Changes -- A Product of Innovators Marketplace on Data Jackets --
Yukio Ohsawa (UT) AI2017-33
Abstract (in Japanese) (See Japanese page) 
(in English) Innovators Marketplace on Data Jackets is a platform for creating not only use scenario of data, but also basic models for computation in data analysis/visualization. Graph-based entropy is an index representing the structural diversity of items, one of the computational models recently created in IMDJ. This proposed index is computed on the co-occurrence graph of items in the data, where the distribution of items to subgraphs is reflected. The variation of this index corresponds to the separation and the combination of events, regarded as effects of latent dynamics or external forces of the target system. In this paper, we show the application of GBE to the analysis of earthquakes, analysis of online Q&A, and marketing with POS data.
