class DogeConfig(PretrainedConfig): |
|
r""" |
|
This is the configuration class to store the configuration of a [`DogeModel`]. It is used to instantiate an Doge |
|
model according to the specified arguments, defining the model architecture like [SmallDoge/Doge-20M](https://huggingface.co/SmallDoge/Doge-20M). |
|
|
|
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 32768): |
|
Vocabulary size of the Doge model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`DogeModel`] |
|
hidden_size (`int`, *optional*, defaults to 1024): |
|
Dimension of the hidden representations. |
|
intermediate_size (`int`, *optional*, defaults to 2048): |
|
Dimension of the MLP representations. |
|
num_hidden_layers (`int`, *optional*, defaults to 32): |
|
Number of hidden layers in the Transformer decoder. |
|

|
Dropout probability for each sequence transformation and state transformation module. |
|

|
The non-linear activation function (function or string) in the decoder. |
|
initializer_range (`float`, *optional*, defaults to 0.02): |
|
The standard deviation of the truncated_normal_initializer for initializing all weight matrices. |
|
rms_norm_eps (`float`, *optional*, defaults to 1e-06): |
|
The epsilon used by the rms normalization layers. |
|
use_cache (`bool`, *optional*, defaults to `True`): |
|
Whether or not the model should return the last key/values attentions (not used by all models). Only |
|
relevant if `config.is_decoder=True`. |
|
bos_token_id (`int`, *optional*, defaults to 0): |
|
Beginning of stream token id. |
|
eos_token_id (`int`, *optional*, defaults to 1): |
|
End of stream token id. |
|
pad_token_id (`int`, *optional*, defaults to 2): |
|
Padding token id. |
|
tie_word_embeddings (`bool`, *optional*, defaults to `False`): |
|
Whether to tie weight embeddings |
|
max_position_embeddings (`int`, *optional*, defaults to 2048): |
|
The maximum sequence length that this model might ever be used with. |
|
rope_theta (`float`, *optional*, defaults to 10000.0): |
|
The base period of the RoPE embeddings. |
|
rope_scaling (`Dict`, *optional*): |
|
Dictionary containing the scaling configuration for the RoPE embeddings. |
|
NOTE: if you apply new rope type and you expect the model to work on longer `max_position_embeddings`, we recommend you to update this value accordingly. |
|
Doge family of small models use `{ 'rope_type': 'dynamic', 'factor': 4.0, 'original_max_position_embeddings': 2048 }` as the default value. |
|
Expected contents: |
|
`rope_type` (`str`): |
|
The sub-variant of RoPE to use. Can be one of ['default', 'linear', 'dynamic', 'yarn', 'longrope', 'llama3'], with 'default' being the original RoPE implementation. |
|
`factor` (`float`, *optional*): |
|
Used with all rope types except 'default'. The scaling factor to apply to the RoPE embeddings. |
|
In most scaling types, a `factor` of x will enable the model to handle sequences of length x * original maximum pre-trained length. |
|
`original_max_position_embeddings` (`int`, *optional*): |
|
Used with 'dynamic', 'longrope' and 'llama3'. |
|
The original max position embeddings used during pretraining. |
|
`attention_factor` (`float`, *optional*): |
|
Used with 'yarn' and 'longrope'. The scaling factor to be applied on the attention |
|
computation. |
|
If unspecified, it defaults to value recommended by the implementation, using the `factor` field to infer the suggested value. |
|
`beta_fast` (`float`, *optional*): |
|
Only used with 'yarn'. Parameter to set the boundary for extrapolation (only) in the linear |
|
ramp function. If unspecified, it defaults to 32. |
|
`beta_slow` (`float`, *optional*): |
|
Only used with 'yarn'. Parameter to set the boundary for interpolation (only) in the linear |
|
ramp function. If unspecified, it defaults to 1. |
|
`short_factor` (`List[float]`, *optional*): |
|
Only used with 'longrope'. The scaling factor to be applied to short contexts (<`original_max_position_embeddings`). |
|
Must be a list of numbers with the same length as the hidden size divided by the number of attention heads divided by 2 |
|
`long_factor` (`List[float]`, *optional*): |
|
Only used with 'longrope'. The scaling factor to be applied to long contexts (<`original_max_position_embeddings`). |
|
Must be a list of numbers with the same length as the hidden size divided by the number of attention heads divided by 2 |
|
`low_freq_factor` (`float`, *optional*): |
|
Only used with 'llama3'. Scaling factor applied to low frequency components of the RoPE |
|
`high_freq_factor` (`float`, *optional*): |
|
Only used with 'llama3'. Scaling factor applied to high frequency components of the RoPE |
|
num_attention_heads (`int`, *optional*, defaults to 8): |
|
Number of attention heads for each attention layer in the Transformer decoder. |
|
num_key_value_heads (`int`, *optional*): |
|
This is the number of key_value heads that should be used to implement Grouped Query Attention. |
|
If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if |
|
`num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. |
|
When converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed by meanpooling all the original heads within that group. |
|
For more details checkout [this paper](https://arxiv.org/pdf/2305.13245.pdf). |
|
If it is not specified, will default to `num_attention_heads`. |
|
attention_dropout (`float`, *optional*, defaults to 0.0): |
|
The dropout ratio for the attention probabilities. |
|
keep_window_size (`int`, *optional*, defaults to 2048): |
|
The window size of tokens that are not dynamically masked, and dynamic masking is only performed when the sequence length exceeds this value. |
|
dynamic_mask_ratio (`float`, *optional*, defaults to 0.0): |
|
The ratio to control the proportion of the dynamic mask filled with the minimum value. For more details checkout [this paper](https://arxiv.org/pdf/2412.11834). |
|
is_moe (`bool`, *optional*, defaults to `False`): |
|
Whether to use the Cross Domain Mixture of Experts, if `True`, the MoE will inherit the MLP to initialize. For more details checkout [this paper](https://arxiv.org/pdf/2412.11834). |
|
num_experts (`int`, *optional*, defaults to 2048): |
|
Number of Experts for the Cross Domain Mixture of Experts. |
|
num_experts_per_tok (`int`, *optional*, defaults to 8): |
|
Number of selected experts to route per-token. |
|
expert_retrieval_size (`int`, *optional*, defaults to 64): |
|
Dimension of the Expert retrieval states for calculating the dot product of query and key to determine the expert index. |
