Author: Sebastian Thrun (Carnegie Mellon University) Source: [UCI](https://archive.ics.uci.edu/ml/datasets/MONK's+Problems) - October 1992 Please cite: [UCI](https://archive.ics.uci.edu/ml/citation_policy.html) The Monk's Problems: Problem 1 Once upon a time, in July 1991, the monks of Corsendonk Priory were faced with a school held in their priory, namely the 2nd European Summer School on Machine Learning. After listening more than one week to a wide variety of learning algorithms, they felt rather confused: Which algorithm would be optimal? And which one to avoid? As a consequence of this dilemma, they created a simple task on which all learning algorithms ought to be compared: the three MONK's problems. The target concept associated with the 1st Monk's problem is the binary outcome of the logical formula: MONK-1: (a1 == a2) or (a5 == 1) In this dataset, the original train and test sets were merged to allow other sampling procedures. However, the original train-test splits can be found as one of the OpenML tasks. ### Attribute information: * attr1: 1, 2, 3 * attr2: 1, 2, 3 * attr3: 1, 2 * attr4: 1, 2, 3 * attr5: 1, 2, 3, 4 * attr6: 1, 2 ### Relevant papers The MONK's Problems - A Performance Comparison of Different Learning Algorithms, by S.B.
