Functionalizer 100M model

This model is presented in the paper The Functionalizer: Lossless Functional Decomposition for Subword Tokenization.

This is a 100M example model. Each model is trained on the dataset specified in the name for 50000 epochs with the given seed.

The model was trained using the Functionalizer framework. Training code and detailed performance analysis are available: https://github.com/connor-makowski/functionalizer

Running the model

To run the model, use the custom tokenizer fork available here: https://github.com/connor-makowski/tokenizers/tree/functionalizer
