WebNov 6, 2024 · for subsequent processing, you can always pass the logits through sigmoid (). Note, you don’t need probabilities to make hard 0-1 predictions: prediction = 1 if logit > 0.0 is the same as prediction = 1 if probability > 0.5. Two side comments: As written, you never call scheduler.step () so scheduler doesn’t do anything. WebDec 4, 2024 · For binary outputs you can use 1 output unit, so then: self.outputs = nn.Linear (NETWORK_WIDTH, 1) Then you use sigmoid activation to map the values of your output …
