+AI4R is a collection of ruby algorithms implementations,
+covering several Artificial intelligence fields. It implements:
+
+ * Genetic algorithms
+ * Self-organized maps (SOM)
+ * Neural Networks
+ - Multilayer perceptron with Backpropagation learning
+ - Hopfield net
+ * Automatic classifiers (Machine Learning)
+ - ID3 (Decision Trees)
+ - PRISM (J. Cendrowska, 1987)
+ - Multilayer Perceptron
+ - OneR (AKA One Attribute Rule, 1R)
+ - ZeroR
+ - Hyperpipes
+ - Naive Bayes
+ - IB1 (D. Aha, D. Kibler - 1991)
+ * Data clustering
+ - K-means
+ - Bisecting k-means
+ - Single linkage
+ - Complete linkage
+ - Average linkage
+ - Weighted Average linkage
+ - Centroid linkage
+ - Median linkage
+ - Ward's method linkage
+ - Diana (Divisive Analysis)
