We usually talk about two main types of machine learning models:

• A Classification model
• A Regression model

They are different, and it's essential to understand why.

↓ 1/6

Whenever the result of your predictions is categorical, you have a classification model.

For example, when your prediction is a binary value (True or False,) or when you want to predict a specific animal from a picture (Lion, Zebra, Horse.)

↓ 2/6

If the result of your predictions is numerical, you have a regression model.

For example, returning a stock's future price, the value of a house, or tomorrow's temperature.

Be aware that "Logistic Regression" is a classification model, not a regression one!

I know. Dumb naming. But it is what it is.

A few examples of problems so you can determine whether they are classification or regression:

1. Predicting the age of a person
2. Predicting the nationality of a person
3. Predicting whether an email is spam or not
4. Predicting the total revenue from a product

5. Predicting the number of products sold
6. Predicting whether it will rain tomorrow
