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

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

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. Thinking of … Siri, Watson, Cleverbot, cortana… From en. wikipedia. org 5

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 6

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

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

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

Treads(Theory Overview) 12

Treads(Theory Overview) 13

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

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

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

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

Treads(Tools) Matlab is not trending 18

Treads(Tools) Python and R are trending 19
