Some Machine Learning algorithms, implemented in python

• K-Means : Randomly generates points and clusters them.
• Linear-Regession : Fits a line through 2D points.
• Naive-Bayes : SMS Spam detection.
• color-scheme-from-image : Builds a Self Organizing Map on image and derive color scheme.
• decision-tree : ID3 decision tree to predict car acceptability with xml serialization for model.
• mining-association-rules : Apriori algorithm to find association rules in retail data.

Some other implementations, in python

• Backpropagation : A modern neural network having one hidden layer.

Some other implementations, in Java 8

• Decision Tree Classifier (ID3) : Determines car acceptability from some properties of the car like price and technical characteristics.
• Logistic Regression : Learns the xor (x^y) function
