In decision tree learning, ID3 (Iterative Dichotomiser 3) is an algorithm invented by Ross Quinlan [1] used to generate a decision tree from a dataset. ID3 is the precursor to the C4.5 algorithm , and is typically used in the machine learning and natural language processing domains.
Ross Quinlan invented the Iterative Dichotomiser 3 (ID3) algorithm which is used to generate decision trees. ID3 follows the principle of Occam's razor in attempting to create the smallest decision tree possible.
Notable decision tree algorithms include: ID3 (Iterative Dichotomiser 3) C4.5 (successor of ID3) CART (Classification And Regression Tree) [7] OC1 (Oblique classifier 1). First method that created multivariate splits at each node. [17] Chi-square automatic interaction detection (CHAID). Performs multi-level splits when computing classification ...
ID3 algorithm (Iterative Dichotomiser 3): use heuristic to generate small decision trees; Clustering: a class of unsupervised learning algorithms for grouping and bucketing related input vector; k-nearest neighbors (k-NN): a non-parametric method for classifying objects based on closest training examples in the feature space
For every 3 non-theme words you find, you earn a hint. Hints show the letters of a theme word. If there is already an active hint on the board, a hint will show that word’s letter order.

C4.5 is an algorithm used to generate a decision tree developed by Ross Quinlan. [1] C4.5 is an extension of Quinlan's earlier ID3 algorithm.The decision trees generated by C4.5 can be used for classification, and for this reason, C4.5 is often referred to as a statistical classifier.
