Hypothesis space
The hypothesis space is the set of all possible mathematical models that can be used to explain a given piece of data. It is typically represented by a set of mathematical expressions, such as linear regression equations or neural networks.
Inductive bias
Inductive bias is a term that refers to the fact that the choice of hypothesis space can have a significant impact on the performance of a machine learning model. A model that is too restricted in its hypothesis space will be less likely to find the optimal solution to a given problem, while a model that is too general will be more likely to make mistakes.
Relationship between hypothesis space and inductive bias
The hypothesis space and inductive bias are closely related. A model that has a large and diverse hypothesis space will be less likely to be biased than a model that has a small and limited hypothesis space. This is because a model with a large hypothesis space is more likely to include models that are not relevant to the problem at hand.
Examples
Hypothesis space: All linear regression models.
Inductive bias: Using linear regression for a problem where the underlying relationship is not linear.
Hypothesis space: All neural networks with a specific architecture.
Inductive bias: Using a simple linear regression model when the underlying relationship is complex
