Learning from data science competitions- baby steps

Off lately a considerable number of winner machine learning enthusiasts have used XGBoost as their predictive analytics solution. This algorithm has taken a preceedence over the traditional tree based algorithms like Random Forests and Neural Networks. The acronym Xgboost stands for eXtreme Gradient Boosting package. The creators of this algorithm presented its implementation by winning the Kaggle Otto…

Data Processing with Weka (Part II)

Today, I will discuss and elaborate on data processing in Weka 3.6 (it’s the same in version 3.7 too). This post is the second part in the series of “Data pre-processing with Weka”. If you have not seen my earlier post, you are directed to see that first. Continuing further, assuming that you have cleaned…
