K-means K-means is an unsupervised learning method for clustering data points. The algorithm iteratively divides data points into K clusters by minimizing the variance in eac...
In Machine Learning we create models to predict the outcome of certain events, like in the previous chapter where we predicted the CO2 emission of a car when we knew the weight and engine size.To measure if the model is good enough, we can use a method called Train/Test....

Machine Learning is a step into the direction of artificial intelligence (AI). Machine Learning is a program that analyses data and learns to predict the outcome. Where To Start? In this tutorial we will go back to mathematics and study statistics, and how to calculate important numbers based...
What can we learn from looking at a group of numbers? In Machine Learning (and in mathematics) there are often three values that interests us: Mean- The average value Median- The mid point value Mode- The most common value Example: We have registered the speed of 13 cars: ...
