- Added a `special_tokens` parameter to allow specifying token IDs (e.g., [CLS], [SEP]) to be excluded from masking. - Updated the eligible mask logic to filter out both special tokens and pad tokens before applying masking. - Refactored the masking process to ensure that only eligible tokens are considered for the 80/10/10 masking scheme.
