What do you mean by hypothesis space, instance space and version space?
Answer:
Hypothesis space 'h' is described by a conjunction of constraints on the attribute, the constraints may General hypothesis "?" ( any value is acceptable), Specific hypothesis "φ" (a specific value or no value is accepted).
Instance Space: It is a subset of all possible example or instance.
Version Space: The Version Space denotes VSHD (with respect to hypothesis space H and training example D) is the subset of hypothesis from H consistent with training example in D.
red: Generalization of Hypothesis.
green: Specification of hypothesis.
yellow: version space.
All the intermediate steps are instance space.
