WebLSTMs in Pytorch¶ Before getting to the example, note a few things. Pytorch’s LSTM expects all of its inputs to be 3D tensors. The semantics of the axes of these tensors is important. The first axis is the sequence itself, the second indexes instances in the mini-batch, and the third indexes elements of the input. WebOct 12, 2024 · 1. I am using a Siamese network with a 2-layer lstm encoder and dropout=0.5 to classify string similarity. For each batch, I am randomly generating similar and dissimilar strings. So, the pytorch model cannot overfit to the training data. When the model is in train () mode, loss is 0.0932, but, if the model is in eval () mode, loss is 0.613. curly sedge creek
