My research objective is modeling complex interactions in high dimensional large-scale time series from various domains. Main research interest is large-scale inference with probabilistic graphical model. Nowadays, I am trying to solve interaction related problems with various Machine Learning algorithms such as Topic Models, Neural Networks for timeseries and various point processes.

The research topic which I have been fascinated is automation of machine learning. Human machine learning experts have led the success of machine learning, applied in various cutting-edge technology industries, in recent years. However the tremendous attention from industries and also academia was not able to make non-experts apply off-the-shelf machine learning algorithms without domain knowledge, although approachable methods through open source packages have been developed. In this context, Bayesian optimization can be used to optimize various types of parameters. Therefore I think it will be a potent strategy for finding the extrema of objective functions that are expensive to evaluate.

I am interested in interpretable machine learning. When machine learning is introduced to the real world problem, the interpretability of the model plays an important role in determining whether the result of the model is reliable. In the case of a general deep neural network model, it is impossible to know which process has been used to derive a specific result, so that even if a wrong decision is made, it is impossible to know whether the result is wrong before the problem occurs. In particular, the interpretability of the model is even more important in order to introduce machine learning into a problem where a misconducted situation causes a very large problem, both socially and morally.

My research topic is mainly about anomaly detection. Anomaly Detection generally means to detect data not observed during training and having some different patterns, and i am studying it based on Deep Generative Model such as Generative Adversarial Networks and Deep Auto-Encoder.
