Monte Carlo method Monte Carlo method is useful in Bayesian data modeling because maximizing posterior probability is often very difficult and fitting a Gaussian becomes hard. Monte Carlo method becomes valuable in that we want to generate samples in some situation, and also want to estimate some expectation values of various functions. What we deal with in this post is only small part of Monte Carlo method. It is going to be good if I have a chance to introduce about all sooner in this blog, but if not, see one of the repositories from my Github

Who can’t use scikit-learn among who is serious about machine learning. It was not difficult to find the theory of spectral clustering as well.

Github is a fantastic space for someone like me to try to learn something new. This time I have built a blog powered by jekyll and Github.

I found jekyll homepage and Sechter’s blog good. I guess you would barely need to look into my posting after going thorough these two websites.
