The 2×2 (or k×k) table of predicted vs actual classes. Every classification metric is just a ratio read off it.
A confusion matrix, also known as error matrix, is a specific table layout that allows visualization of the performance of a person or an algorithm on a specific task. In audiology these matrices measure how a person can hear specific words or sounds. In machine learning these matrices show the success of the learning system both in Supervised Learning and Unsupervised Learning, where they are usually called matching matrix.
