WitrynaThe intuition is: the model is fitting data and filling in where data is missing, so the imputer built on your training data is the model's best approximation for guessing the missing value. But remember, train the imputer on the training set only, otherwise the imputer is learning from data it should not have "seen". – Savage Henry Witryna1 cze 2024 · More formally, the uniqueness or (k, e)-mappability can be described for every position as the reciprocal value of how often this k-mer occurs approximately in the genome, i.e. with up to e mismatches. Results: We present a fast method GenMap to compute the (k, e)-mappability.
