❏ Abstract

① Inference of rankings from data: Bayesian-approach to determining dominance

hierarchy

Bayes' theorem, first formulated by the British mathematician Thomas Bayes in the 18th

century, still functions as the standard methodology by which one's distribution of a

parameter is updated according to the unearthing of new empirical evidence. Here we

apply this method to the problem of ranking nodes in a competition network, which

produces a confidence interval in the rankings, unlike centrality-based methods.

② Predicting the Stock Market with Unstructured Media Texts

I present the result of predicting the stock market index with unstructured media texts.

The stock market index is a single measurement of a collective behavior of investors,

and from such perspective, I conjecture that the collective would be better explained

by utilizing the media data generated by the individuals in the collective. I compare

and contrast the prediction accuracy and the values of the traditional economic

indicators as well as the recent unstructured text-mining data.

③ Cracking the code in social interactions

My general research goal is in automatically analyzing various social interactions in

order to gain understanding on social phenomena and using that understanding to

improve quality of life (e.g. education, relationships). Analyzing and making sense of

social interactions, more specifically conversations, is analogous to cracking the code

that’s hidden under seemingly ordinary conversations. In this talk, I highlight the

necessity of such research along with some example research work in this area.
