This document discusses Mahout, an Apache project for machine learning algorithms like classification, clustering, and pattern mining. It describes using Mahout with Hadoop to build a Naive Bayes classifier on Wikipedia data to classify articles into categories like "game" and "sports". The process includes splitting Wikipedia XML, training the classifier on Hadoop, and testing it to generate a confusion matrix. Mahout can also integrate with other systems like HBase for real-time classification.
This document discusses Python and machine learning libraries like scikit-learn. It provides code examples for loading data, fitting models, and making predictions using scikit-learn algorithms. It also covers working with NumPy arrays and loading data from files like CSVs.
