Statistical classification is a problem studied in machine learning. It is a type of supervised learning, a method of machine learning where the categories are predefined, and is used to categorize new probabilistic observations into said categories. When there are only two categories the problem is known as statistical binary classification. Some of the methods commonly used for binary classification are: WebDec 12, 2024 · Iosifidis A Tefas A Pitas I On the kernel extreme learning machine classifier Pattern Recogn Lett 2015 54 11 17 10.1016/j.patrec.2014.12.003 Google ...
