WHAT ML CAN BE USED FOR?

CLASSIFICATION PREDICTION

9

PRIMARY TECHNIQUES: SUPERVISED LEARNING

Used when you want to predict unknown answers from answers you already have

6. Select the best model

5. Evaluate results using

test set

Go to 3?

4. Apply algorithm(s) on data set

3. Build model

2. Split into training and

test sets

1. Clean up and

supplement data

0. Data

SUPERVISED LEARNING ON PRACTICE

• Two legs, two hands

• Commonly two eyes, but some of them have one only

• Wear safety glasses

• Yellow skin

• No neck

HOW TO RECOGNIZE A MINION?

OK

OK

PRIMARY TECHNIQUES: UNSUPERVISED LEARNING

1. Used when you want to find unknown answers – mostly groupings - directly from data

2. No simple way to evaluate accuracy of what you learn

3. Evaluates more vectors, groups into sets or classifications

Evaluate groups
