Many people have asked me how I create the table of contents with internal links for my IPython Notebooks and Markdown documents on GitHub. Well, no…
This blog post is the second part of an article series on Dirichlet Process mixture models. In the previous article we had an overview of several Cluster Analysis techniques and we discussed some of the problems/limitations that rise by using them. Mor…
A short tutorial about Python’s namespaces and the scope resolution for variable names using the LEGB-rule with little quiz-like exercises.
In the ISO research project for my MSc in Machine Learning at Imperial College London, I focused on the problem of Cluster Analysis by using Dirichlet Process Mixture Models. The DPMMs is a “fully-Bayesian” unsupervised learning technique which unlike …
Some while ago, I started to collect some of the not-so-obvious things I encountered when I was coding in Python. I thought that it was worthwhile sharing…
In this article I want to explain how a Principal Component Analysis (PCA) works by implementing it in Python step by step. At the end we will compare the…
By now most of you have heard/played the 2048 game by Gabriele Cirulli. It’s a simple but highly addictive board game which requires you to combine the numbers of the cells in order to reach the number 2048. As expected the difficulty of the game incre…
I just went through some pain (again) when I wanted to install some of Python’s scientific libraries on my second Mac. I summarized the setup and…
After I wrote the initial teaser article “SQLite – Working with large data sets in Python effectively” about how awesome SQLite databases are via sqlite3 in…
In the previous article we have discussed about the Data Envelopment Analysis technique and we have seen how it can be used as an effective non-parametric ranking algorithm. In this blog post we will develop an implementation of Data Envelopment Analys…
