Everyone can do data analysis in this era of data-driven society. However, not everyone can extract the correct science from data. In this talk, we will present some simple, yet not trivial, rules that guide us to convert big data to "smart data". We will also discuss the curses and blessings of computer-intensive big data analysis. Topics covered in this talk include differential privacy, missing data handling and Markov chain Monte Carlo. We will conclude the talk by introducing a brand-new academic programme at CUHK, Computational Data Science (CDAS).
