# Machine Learning with Python

* Machine Learning is the Field of study that Gives Computers the ability to learn without being Explicitly Programmed.
    
* It is the subset of AI, which enables the Machine to Automatically Learn from data, improve performance from past experience and make predictions.
    
* A Computer Program is said to learn from **Experience E** with respect to some **Task T** and some **performance measure P**, if its performance on T, as measured by P, improves with **Experience E**.
    

### **Traditional Programing**

### Let’s see Example

Teach a computer to follow traffic Light Rules

1. If Red, stop car and turn off engine.
    
2. Else if yellow start your car Engine.
    
3. Else If green go!!

* Simple and a smaller number of rules
    
* Easy to program.
    

Why even bother with Machine Learning?

### Why we Use Machine Learning?

Teach a computer to Identify

* Running
    
* Jumping
    
* Walking

In this Image Can you right the rules?

How many rules do need to be right?

### **Machine Learning Approach**

### Types of Machine Learning

* Supervised Learning
    
* Unsupervised Learning
    

### Supervised Learning

A type of Machine Learning which requires a human Labelled Dataset, which provides the necessary supervision during Training a ML Algorithm.

### What is Training? What is dataset?
