class fl_sim.models.RNN_Sent140(latent_size: int = 100, num_classes: int = 2, num_layers: int = 2, embedding: str | object = 'glove.6B.50d')[source]#

Bases: Module, CLFMixin, SizeMixin, DiffMixin

Stacked LSTM model for sentiment analysis on the Sent140 dataset.

Adapted from FedProx/flearn/models/sent140/stacked_lstm.py [1].

Parameters:

  • latent_size (int, default 100) – The number of features in the hidden state h.

  • num_classes (int, default 2) – The number of output classes.

  • num_layers (int, default 2) – The number of recurrent layers (LSTM).

  • embedding (str or GloveEmbedding, default “glove.6B.50d”) – The name of the pre-trained GloVe embedding to use or a GloveEmbedding object.
