Pytorch rnn sentiment analysis

Step 4: Build Model. We construct the LSTM class that inherits from the nn.Module. Inside the LSTM, we construct an Embedding layer, followed by a bi-LSTM layer, and ending with a fully connected linear layer. In the forward function, we pass the text IDs through the embedding layer to get the embeddings, pass it through the LSTM accommodating.

Code. 4 commits. Recurrent Neural Networks. ¶. Sentiment Analysis is the problem of identifying the writer's sentiment given a piece of text. Sentiment Analysis can be applied to movie reviews, feedback of other forms, emails, tweets, course evaluations, and much more. Rudimentary forms of sentiment analysis might involve scoring each word on a scale from "sad.
Here I have defined the optimizer, loss and metric for the model: There are 2 phases while building the model: Training phase: model.train () sets the model on the training phase and activates the dropout layers. Inference phase: model.eval () sets the model on the evaluation phase and deactivates the dropout layers.

As you want to learn a sentiment analysis model, then there will be 3 possibilities I guess : neutral, positive & negative i.e. 3 classes. So either use the output of last hidden state (or pool the output of all the hidden states) to get a vector of shape (batch_size, 2*hidden_dim).

For anyone that might land up here, BCELoss seems to have an issue in PyTorch. Switching to CrossEntropy loss even for a binary classification task, solved my problem. In summary, if you architecture is right, double check the choice of loss functions and the way the true labels have to be prepared, as expected by the loss function.
