What is a Hypothesis in Machine Learning?

Supervised machine learning is often described as the problem of approximating a target function that maps inputs to outputs. This description is characterized as searching through and evaluating candidate hypothesis from hypothesis spaces. The discussion of hypotheses in machine learning can be confusing for a beginner, especially when "hypothesis" has a distinct, but related meaning in statistics (e.g. In this post, you will discover the difference between a hypothesis in science, in statistics, and in machine learning.
