機器學習的發展可以追溯到1959年，有著豐富的歷史。這個領域也正在以前所未有的速度進化。在之前的一篇文章（https://unsupervisedmethods.com/why-artificial-intelligence-is-different-from-previous-technology-waves-764d7710df8b）中，我們討論過為什麼通用人工智慧領域即將要爆發。有興趣入坑ML的小夥伴不要拖延了，時不我待！
在今年秋季開始準備博士項目的時候，我已經精選了一些有關機器學習和NLP的優質網絡資源。一般我會找一個有意思的教程或者視頻，再由此找到三四個，甚至更多的教程或者視頻。猛回頭，發現標收藏夾又多了20個資源待我學習（推薦提升效率工具Tab Bundler）。
找到超過25個有關ML的「小抄」後，我寫一篇博文（https://unsupervisedmethods.com/cheat-sheet-of-machine-learning-and-python-and-math-cheat-sheets-a4afe4e791b6），裡面的資源都有超連結。
為了幫助也在經歷類似探索過程的童鞋，我把至今發現的最好的教程匯總了一個列表。當然這不是網絡上有關ML的最全集合，而且其中有一部分內容很普通。我的目標是要找到最好的有關機器學習子方向和NLP的教程。
我引用了能簡潔介紹概念的基礎內容。我已經迴避包含一些大部頭書的章節，和對理解概念沒有幫助的科研論文。那為什麼不買一本書呢？ 因為教程能更好地幫助你學一技之長或者打開新視野。
我把這博文分成四個部分，機器學習，NLP，Python，和數學基礎。在每一小節我會隨機引入一些問題。由於這方面學習材料太豐富了，本文並未涵括所有內容。
