WebDec 25, 2024 · In order to map probabilities [0,1] to R [-inf, inf], logits function must be used. L=ln(p/1-p) p=1/1+e-L. A better understanding of how likely a prediction is allows for more accurate predictions. Logits Meaning. Logits are the raw values that a neural network outputs. They are unbounded and can be positive or negative. WebMay 27, 2024 · However, if we avoid passing in a labels parameter, the model will only output logits, which we can use to calculate our own loss for multilabel classification. outputs = model (batch_input_ids, token_type_ids=None, attention_mask=batch_input_mask, labels=batch_labels) logits = outputs [0] Below is …
