WebFor these special cases, we have defined that if the true positives, false positives and false negatives are all 0, the precision, recall and F1-measure are 1. This might occur in cases in which the gold standard contains a document without any annotations and the annotator (correctly) returns no annotations. WebFor these special cases, we have defined that if the true positives, false positives and false negatives are all 0, the precision, recall and F1-measure are 1. This might occur in cases …
A Look at Precision, Recall, and F1-Score by Teemu Kanstrén
WebRegarding the nan in your f1 metric: If you look at the log, your validation sensitivity is 0. Which means your precision and recall are both zero as well. So in the f1 calculation you are dividing by zero and getting a nan. Add K.epsilon(), as you have done in the other … WebMay 22, 2024 · Indeed, I forgot to mention this detail. Before getting nans (all the tensor returned as nan by relu ) , I got this in earlier level , in fact there is a function called squashing in which there is kind of making the values between 0 and 1 below the code: def squash (self, input_tensor): squared_norm = (input_tensor ** 2).sum (-1, keepdim=True) has anything been found on oak island yet
