什么是機器學習(個人理解
Two definitions of Machine Learning are offered. Arthur Samuel
described it as: “the field of study that gives computers the ability
to learn without being explicitly programmed.” This is an older,
informal definition.Tom Mitchell provides a more modern definition: “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.”
- 機器學習就是計算機能夠在無需明確編程的情況下進行學習,
有時計算機所進行的程式和動作是我們事先編程好的,就好像我們已經寫好了說明書,計算機只需要按照步驟一步一步進行即可,而機器學習就是計算機可以進行一些動作,但這些動作并不在我們的說明書內, - 對于某類任務T和性能度量P,一個計算器程式在T上以P衡量的性能隨著經驗E而自我完成,那么我們稱這個計算機程式在從經驗E學習,
如果計算機是一個名叫小小豪的孩子,那么他的學習能力就是P,而E就是他所學到的東西,T就是他的作業,根據學到的東西,基于學習的能力而完成的作業,就是他的學習程序,
