Topic 2B Part 1 – Supervised Learning
There are three kinds of ML problems (or tasks) – this topic is split into three parts to explain each of them.
Supervised Learning is a method of training an algorithm where a data set consists of two parts: The data itself and a label. For example, a picture of a strawberry and a label which describes it as a strawberry.
The algorithm is rewarded when it predicts the correct label, and it can rearrange itself if it predicts the wrong label.
Similarly, the data can be associated with a real number, representing for example a geophysical parameter, rather than with a label. This is an example of regressions, where the task is to predict a continuous quantity.
This can be used to do two things:
- Classification: sorting data into classes
- Regression: parameter estimation
