Manuscripts in review and work in process: 

• Machine learning with missing data

Inspiring quotes:

• George Box,  "All models are wrong, but some are useful.... Since all models are wrong, the scientist must be alert to what is importantly wrong. It is inappropriate to be concerned about mice when there are tigers abroad."

• George Dantzig, "All such problems can be formulated as mathematical programming problems. Naturally, we can propose many sophisticated algorithms and a theory but the final test of a theory is its capacity to solve the problems which originated it." (1963, in Linear Programming and Extensions)

• Albert Einstein (愛因斯坦), "It is not that I'm so smart. But I stay with the questions much longer."

• Kurt Lewin, "There is nothing as practical as a good theory." (1943, in Psychology and the process of group living, Journal of Social Psychology) (懂不懂微積分的差別)
