Tom M. Mitchell provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T, as measured by P, improves with experience E."
Tom Michael Mitchell on öelnud masinõppimise formaalseks definitsiooniks laialt tsiteeritud lause: "Arvutiprogramm õpib kogemusest E ülesannete klassi T ja tulemuste mõõdu P suhtes, kui selle tulemuslikkus klassi T ülesannetes, nii nagu mõõdetud P kaudu, paraneb kogemusega E."
