I recently competed in a CrowdAnalytix competition to predict worsening symptoms of COPD. Our team (Marios Michailidis, Phil Culliton, Vivant Shen and me) finished in the money. Here is how we managed this.
COPD
COPD (Chronic Obstructive Pulmonary Disease) is a lung disease that makes it hard to breath. People with COPD experience exacerbation: A sudden worsening of the symptoms. Symptoms of COPD exacerbation include:...

Model ensembling is a very powerful technique to increase accuracy on a variety of ML tasks. In this article I will share my ensembling approaches for Kaggle Competitions.
For the first part we look at creating ensembles from submission files. The second part will look at creating ensembles through stacked generalization/blending....

Let’s take a look at the perceptron: the simplest artificial neuron. This article goes from a concept devised in 1943 to a Kaggle competition in 2015. It shows that a single artificial neuron can get 0.95 AUC on an NLP sentiment analysis task (predicting...

Previously we looked at detecting counterfeit webshops and feature engineering. Now we will show some progress and learn from our insights (and mistakes) competing in a related Kaggle challenge.
Vowpal Wabbit close to for the win
Kaggle hosted a contest together with Avito.ru. The task was to automatically detect illicit content in the advertisements on their site....
