It is used to instantiate a MobileBERT model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the MobileBERT [google/mobilebert-uncased](https://huggingface.co/google/mobilebert-uncased) architecture. Configuration objects inherit from [`PreTrainedConfig`] and can be used to control the model outputs. Read the documentation from [`PreTrainedConfig`] for more information. Args: vocab_size (`int`, *optional*, defaults to 30522): Vocabulary size of the MobileBERT model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`MobileBertModel`]. hidden_size (`int`, *optional*, defaults to 512): Dimensionality of the encoder layers and the pooler layer. num_hidden_layers (`int`, *optional*, defaults to 24): Number of hidden layers in the Transformer encoder. num_attention_heads (`int`, *optional*, defaults to 4): Number of attention heads for each attention layer in the Transformer encoder. intermediate_size (`int`, *optional*, defaults to 512): Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder. hidden_act (`str` or `function`, *optional*, defaults to `"relu"`): The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`, `"relu"`, `"silu"` and `"gelu_new"` are supported. hidden_dropout_prob (`float`, *optional*, defaults to 0.0): The dropout probability for all fully connected layers in the embeddings, encoder, and pooler. attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1): The dropout ratio for the attention probabilities. max_position_embeddings (`int`, *optional*, defaults to 512): The maximum sequence length that this model might ever be used with. Typically set this to something large just in case (e.g., 512 or 1024 or 2048). type_vocab_size (`int`, *optional*, defaults to 2): The vocabulary size of the `token_type_ids` passed when calling [`MobileBertModel`]. initializer_range (`float`, *optional*, defaults to 0.02): The standard deviation of the truncated_normal_initializer for initializing all weight matrices. layer_norm_eps (`float`, *optional*, defaults to 1e-12): The epsilon used by the layer normalization layers. pad_token_id (`int`, *optional*, defaults to 0): The ID of the token in the word embedding to use as padding. embedding_size (`int`, *optional*, defaults to 128): The dimension of the word embedding vectors. trigram_input (`bool`, *optional*, defaults to `True`): Use a convolution of trigram as input. use_bottleneck (`bool`, *optional*, defaults to `True`): Whether to use bottleneck in BERT. intra_bottleneck_size (`int`, *optional*, defaults to 128): Size of bottleneck layer output. use_bottleneck_attention (`bool`, *optional*, defaults to `False`): Whether to use attention inputs from the bottleneck transformation. key_query_shared_bottleneck (`bool`, *optional*, defaults to `True`): Whether to use the same linear transformation for query&key in the bottleneck. num_feedforward_networks (`int`, *optional*, defaults to 4): Number of FFNs in a block. normalization_type (`str`, *optional*, defaults to `"no_norm"`): The normalization type in MobileBERT. classifier_dropout (`float`, *optional*): The dropout ratio for the classification head.
