Architectures

"input_ids" - {batch_size, sequence_length}
Indices of input sequence tokens in the vocabulary.
"attention_mask" - {batch_size, sequence_length}
Mask indicating which tokens to attend to. This is used to ignore padding tokens, which are added when processing a batch of sequences with different length.
"position_ids" - {batch_size, sequence_length}
Indices of positions of each input sequence tokens in the position embeddings.

:vocab_size - the vocabulary size of the token embedding. This corresponds to the number of distinct tokens that can be represented in model input and output . Defaults to 49408
:max_positions - the vocabulary size of the position embedding. This corresponds to the maximum sequence length that this model can process. Typically this is set to a large value just in case, such as 512, 1024 or 2048 . Defaults to 77
:hidden_size - the dimensionality of hidden layers. Defaults to 512
:num_blocks - the number of Transformer blocks in the encoder. Defaults to 12
:num_attention_heads - the number of attention heads for each attention layer in the encoder. Defaults to 8
:intermediate_size - the dimensionality of the intermediate (often named feed-forward) layer in the encoder. Defaults to 2048
:activation - the activation function. Defaults to :quick_gelu
:attention_dropout_rate - the dropout rate for attention weights. Defaults to 0.0
:layer_norm_epsilon - the epsilon used by the layer normalization layers. Defaults to 1.0e-5
:output_hidden_states - whether the model should return all hidden states. Defaults to false
:output_attentions - whether the model should return all attentions. Defaults to false
:num_labels - the number of labels to use in the last layer for the classification task. Defaults to 2
:id_to_label - a map from class index to label. Defaults to %{}
