WebMay 30, 2024 · After my first version using a for-loop has proven inefficient, this is the fastest solution I came up with so far, for two equal-dimensional tensors prediction and truth: def confusion (prediction, truth): confusion_vector = prediction / truth true_positives = torch.sum (confusion_vector == 1).item () false_positives = torch.sum (confusion ... WebA metric, Fisher information matrix, naturally arises in the maximum likelihood estimation as a measure of independency between estimated parameters [2,3,6,23]. As the inverse of the Fisher information matrix gives the covariance matrix for the estimation errors of the parameters, the orthogonalization of the parameters guarantees that birthday borders clip art free
