2 2 Agenda What is Machine Learning ? Treads (Theory + Tools) Demo (Jupyter+Scikit-Learn )

3 3 What is Machine Learning ? “A Field of study that gives computers the ability to learn without being explicitly programmed“ —— Arthur Samuel

4 4 What is Machine Learning ? What is not Machine Learning? Deep search is not machine learning !

5 5 What is Machine Learning ? Objective? Better approaching Turing Test than common algorithm The evaluator C would be aware that one of the two partners in conversation is a machine. From en.wikipedia.org Thinking of … Siri, Watson, Cleverbot, cortana…

6 6 What is Machine Learning ? Objective ? A core objective of a learner is to generalize(predict) from its experience To computer, experience is all about : DATA

7 7 What is Machine Learning ? How? Gather Data Clean Data Prepare input for ML Machine Learning Algorithm Test model on real data Visualise Data

8 8 What is Machine Learning ? How? Example: Train an linear classifier ? Problem explained

9 9 What is Machine Learning ? How? Example: Train an linear classifier Based on samples, train a model (y = x*a + b) parameter: a, b

10 10 What is Machine Learning ? How? Example: Train an linear classifier Which model is better ? ?

11 11 What is Machine Learning ? How? Example: Train an linear classifier Which model is better ?

12 12 Treads(Theory Overview)

13 13 Treads(Theory Overview)

14 14 Treads(Theory) Deep Learning is leading the race !

15 15 Treads(Theory) ( Yann LeCun , Geoffrey Hinton, Yoshua Bengio, Andrew Ng) Geoff Hinton ------ Google , Google Brain Yann Lecun ------ Director of AI Research, Facebook Yoshua Bengio ------ Université de Montréal Andrew Ng (吴恩达) ------ Baidu Brain

16 16 Treads(Theory) “Don‘t model the World, Model the Mind.”

17 17 Treads(Theory) “Data is king, algorithm is queen.” “ 数据是燃料, 算法是火箭 ” ------ 吴恩达

18 18 Treads(Tools) Matlab is not trending

19 19 Treads(Tools) Python and R are trending
