VerifiedTop-P (nucleus sampling) samples from the smallest set of tokens whose cumulative probability exceeds the threshold P, while Top-K selects only from the K candidates with the highest probabilities.80% similarUnverifiedTop-K retrieval refers to returning the top K chunks with the highest similarity during the retrieval stage, and K is usually taken from 3 to 10.79% similarUnverifiedThe value of K in Top-K should be determined through offline evaluation by measuring Recall@K at different K values on an annotated test set and finding the inflection point where the recall curve begins to flatten.77% similarUnverifiedThe K value for Top-K precomputation typically falls between 5 and 20, aligned with the number of suggestions displayed in the user interface, and the index size grows linearly with K.77% similarUnverifiedTop-K SAE retains only the K features with the highest activation values during encoding and forces all others to zero, thereby compelling the model to learn sparse representations.73% similar
