This is awesome! Could you share more details on how you’re storing the image embeddings and performing the KNN search? Is there an on-device vector database for iOS?
Thanks for your attention. I did not use any database, but stored the embedding calculations as Object files. When the user opens the app, the program preload them and turn them into `MLMultiArray`. when the user searches, these `MLMultiArray` are traversed and the similarity is calculated separately.
