Method configure()

Configures a new object of this class.

Usage

BaseModelFunnel$configure(
  tokenizer,
  max_position_embeddings = 512L,
  hidden_size = 768L,
  block_sizes = c(4L, 4L, 4L),
  num_attention_heads = 12L,
  intermediate_size = 3072L,
  num_decoder_layers = 2L,
  d_head = 64L,
  funnel_pooling_type = "Mean",
  hidden_act = "GELU",
  hidden_dropout_prob = 0.1,
  attention_probs_dropout_prob = 0.1,
  activation_dropout = 0
)

Arguments

tokenizer

TokenizerBase Tokenizer for the model.

max_position_embeddings

int Number of maximum position embeddings. This parameter also determines the maximum length of a sequence which can be processed with the model. Allowed values: 10 <= x <= 4048

hidden_size

int Number of neurons in each layer. This parameter determines the dimensionality of the resulting text embedding. Allowed values: 1 <= x <= 2048

block_sizes

vector vector of int determining the number and sizes of each block.

num_attention_heads

int determining the number of attention heads for a self-attention layer. Only relevant if attention_type='multihead' Allowed values: 0 <= x

intermediate_size

int determining the size of the projection layer within a each transformer encoder. Allowed values: 1 <= x

num_decoder_layers

int Number of decoding layers. Allowed values: 1 <= x

d_head

int Number of neurons of the final layer. Allowed values: 1 <= x

funnel_pooling_type

string Method for pooling over the seqence length. Allowed values: 'Mean', 'Max'

hidden_act

string Name of the activation function. Allowed values: 'GELU', 'relu', 'silu', 'gelu_new'

hidden_dropout_prob

double Ratio of dropout. Allowed values: 0 <= x <= 0.6

attention_probs_dropout_prob

double Ratio of dropout for attention probabilities. Allowed values: 0 <= x <= 0.6

activation_dropout

double Dropout probability between the layers of the feed-forward blocks. Allowed values: 0 <= x <= 0.6

num_hidden_layers

int Number of hidden layers. Allowed values: 1 <= x

Returns

Does nothing return.
