Machine Learning tutorial | Accuracy(MAE/RMSE) | Artificial Intelligence | Unsupervised learning, Supervised Learning and Reinforcement Learning | k-fold or 5-fold cross validation

The MAE measures the average magnitude of the errors in a set of forecasts, without considering their direction
The RMSE is a quadratic scoring rule which measures the average magnitude of the error.

Interested in machine learning or do you just want to make a recommender system on your own? Then this course is all you need! You will learn how to crawl data(data mining), setup a database for storing data and then use this data to recommend items to the users within your system.

Hi,
small error in the MAE calculation at 3:23, you do not take the absolute value of |4-4.5|=0.5, so instead on 1.5/3 it's 2.5/3=0.83. Which makes all your explanation false after :/.
