The area of text classification has attracted a lot of interest from both the machine learning research community and the industry. One popular application of text classification is sentiment analysis, whose objective is to guess the positive or negative attitude of a user towards a topic given a sentence. In this post I will give an overview of how to apply machine learning techniques to text classification and sentiment analysis.

Lean Startup has been a breakthrough during the last years in the entrepreneurial landscape. But this movement is not only a methodology that can be used to create successful businesses, it can also be applied to other domains like Data Science. In this post, I will discuss how to apply the Lean Startup method to a Data Science project. As an example, I created a project that visualizes all football matches that took place in the UEFA Champions League since 1955.


A Gentle Introduction to Convolutional Neural Networks

Sept. 30, 2016

Convolutional Neural Networks (CNN) are one of the key components in the success of Deep Learning and the new Artificial Intelligence revolution. They are specially advantageous in tasks such as object detection, scene understanding and, recently, natural language processing. In this post I will explain what are CNN, what is the intuition behind them and provide an example of its performance in character recognition.
