Is there any metric for calculating how natural a single image is given a dataset of the same class images?

Suppose there is a dataset $D$ of images. We have enough number $n$ of images in the dataset and all the images are of a single class. Suppose I generated a new image $I$, which is not present in the ...

Encode states based on after-the-fact Similarity?

The question is what can you do in case where encoding STATE SIMILARITY is dependent on the interaction i.e. it is known after the fact. For example in chess you may have a State’s (S1 and S2) where a ...
