“A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E” - Tom M. Mitchell
WHAT IS ML?

DEFENITION FOR HUMANS
“The goal of machine learning is to program computers to use example data or past experience to solve a given problem.” – Introduction to Machine Learning, 2nd Edition, MIT Press

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

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
Apply algorithm(s)Data
