FLOTA
This repository contains the code and data for the ACL paper An Embarrassingly Simple Method to Mitigate Undesirable Properties of Pretrained Language Model Tokenizers. The paper introduces FLOTA (Few Longest Token Approximation), a simple yet effective method to improve the tokenization of pretrained language models.
Dependencies
The code requires Python>=3.8, numpy>=1.18, pandas>=1.1, torch>=1.2, and transformers>=4.12.
Data
The ArXiv challenge sets can be found in data.
Usage
To replicate the main experiment, run the script run_main.sh in src.
To replicate the experiment on the impact of k, run the script run_k.sh in src.
To replicate the experiment with noisy input, run the script run_noise.sh in src.
The scripts expect the dataset files in data.
