Binary classification loss

WebIn machine learning, binary classification is a supervised learning algorithm that categorizes new observations into one of two classes. The following are a few binary classification applications, where the 0 and 1 columns are two possible classes for each observation: Application Observation 0 1; Medical Diagnosis: Patient: Healthy: Web1 day ago · This is a binary classification( your output is one dim), you should not use torch.max it will always return the same output, which is 0. Instead you should compare the output with threshold as follows: threshold = 0.5 preds = (outputs >threshold).to(labels.dtype)
