Dropout in last layer

[Fayyaz ul Amir Afsar Minhas]

Thank you for your work.
You have used dropout prior to computing the output from each layer. What is the role of this dropout?
See:

powerful-gnns/models/graphcnn.py

Line 225 in f2626e7

 score_over_layer += F.dropout(self.linears_prediction[layer](pooled_h), self.final_dropout, training = self.training)

It's just a regularization.

Thank you for your response - Tome, it makes sense to regularize using dropout at layers before the last one. Dropout at the prediction output forces prediction scores of an example to become zero and also scales up the prediction scores of other examples in the batch. Please see: "Furthermore, the outputs are scaled by a factor of \frac{1}{1-p}" in https://pytorch.org/docs/stable/generated/torch.nn.Dropout.html
It would be great if you could help me understand this a bit better. Thanks, again.
