Train and Test

Train and Test

Train and Test is a core part of Machine Learning. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding train and test well means you can read other people's Machine Learning code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What train and test means in the context of Machine Learning
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with train and test

# Machine Learning: Train and Test
def demo():
    print("Exploring Train and Test in Machine Learning")

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for train and test.
