It is supposed that intelligence is the ability to efficiently deal with novelty. Thus, it is important to understand how the brain discovers novelty vis-a-vis existing knowledge and skills and how these are modified at the level of the brain to serve the "novelty" one is currently dealing with
I'm not an expert in novelty detection but observe the scene.
In olden times there was a neural net type for detecting novelties.
Such a detector is described here.

Modern research found novelty detectors in the brain.

My own opinion is that deciding whether a pattern is new
or a version of a previously stored one is a matter
of taste, a matter of judgment, on every level of intelligence.
Even in model worlds like chess, questions like "is this
opening new or a variant of a well-known old one"
would probably lead to endless debates among
the players.

Hi Joachim:
Many thanks. This is very useful. Of course even when we capture the functioning of novelty detection neurons or networks, we will have to understand how this operates in a decision making process that differentiates individuals in how novelty is used for the production of optimal problem solutions and/or decisions. This is basically a developmental question.

In the novelty-detection mechanism that I have proposed in The Cognitive Brain, the novelty of a stimulus is determined by the latency to classify the stimulus pattern.
Yes. See The Cognitive Brain (TCB), "Novelty Detection", pp. 83 - 85, here:

And for an example of how the detection of novelty relates to learning, see TCB, "Self-Directed Learning in a Complex Environment", here:
