Model description

This model is a fine-tuned version of google/byt5-small on a more balanced iteration of the NL2BASH dataset. It achieves the following results on the evaluation set:

• Loss: 0.4850
• Nl2bash M: 0.6376
• Gen Len: 16.9946

Intended uses & limitations

Purpose: To generate bash commands from text input, and help people learn to use linux bash. This is a proof of concept model using transfer learning to fine-tune an existing language model and produce structured code instead of natural language.

Training and evaluation data

This model was trained and evaluated using a custom iteration of NL2BASH. The original NL2BASH dataset contains a large class imbalance with too many bash commands which begin with 'find'.

A maximum threshold was set to remove text/BASH pairs which exceeded the threshold, and GPT-3 API was used to generate text/BASH pairs for those below the threshold.

~5500 original text/BASH pairs and ~5700 generated text/BASH pairs were used, giving a total of ~11200 lines of text/BASH pairs. Shown below is the class distribution for the top-5 commands.
