Method configure()

Configures a new object of this class. Please ensure that your chosen configuration comply with the following guidelines:

• hidden_size is a multiple of num_attention_heads.

Usage

BaseModelBert$configure(
  tokenizer,
  max_position_embeddings = 512L,
  hidden_size = 768L,
  num_hidden_layers = 12L,
  num_attention_heads = 12L,
  intermediate_size = 3072L,
  hidden_act = "GELU",
  hidden_dropout_prob = 0.1,
  attention_probs_dropout_prob = 0.1
)

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

num_hidden_layers

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

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

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

Returns

Does nothing return.

Method clone()

The objects of this class are cloneable with this method.

Usage

BaseModelBert$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
