Nettet25. okt. 2024 · I'm looking to find a similarity metric that will specify how similar this instance <8,4 5,1> is to the entire dataset. I'd appreciate if I could get a technique that doesn't make any assumption regarding the distribution of the data and also isn't computationally intensive (although a tradeoff might have to be made at some point). Nettet1. mar. 2024 · In this paper, we introduce the notion of instance similarity, which is used to evaluate the semantic correlation between two specific instances in training data. We also propose a deep instance hashing networks method based on the instance similarity, to boost cross-modal hashing by introducing the instance similarity …
