(Ken Cen出品)從零開始學Machine Learning第一部 - 線型回歸，分類與聚類

Ken Cen

課程內容包括Python，機械學習，及各種實際運用的實例。本課程將從零基礎開始學習Python語言，了解Python的基本語言，學習Machine Learning的數據處理庫Numpy，Pandas，數據可視化工具庫Matplotlib等。然後，開始了解，Machine Learning 中的Linear Regression，Classification，Clustering，以及對應的演算法，和各種或然率概念。

人工智能是現在最流行和熱門的話題，人才需求也非常巨大，然而，要學習了解這門科學，卻非常困難，原因在於這是一個集中多學科，包括Pyhon語言學習，對應Numpy， Pandas等數據處理，還有數學中，統籌學，或然率概念，方程式等複雜概念。

課程會回歸一個無任何編程經驗的學員角度，一步一步了解實踐這門科學，這將是一個奇妙學習的旅程，希望能與您結伴同行！
