WebMar 25, 2024 · Introduction. A Siamese Network is a type of network architecture that contains two or more identical subnetworks used to generate feature vectors for each input and compare them.. Siamese Networks can be applied to different use cases, like detecting duplicates, finding anomalies, and face recognition. This example uses a Siamese … 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. jesus olmo transfermarkt
