CMG/CMC: CodeT5 (without history)

This is the checkpoint for CodeT5 model, fine-tuned for the commit message generation (and/or completion) task as part of the paper "From Commit Message Generation to History-Aware Commit Message Completion", ASE 2023.

• Paper: https://arxiv.org/abs/2308.07655
• Repository: https://github.com/JetBrains-Research/commit_message_generation

• This model is based on Salesforce/codet5-base checkpoint from 📜 CodeT5: Identifier-aware Unified Pre-trained Encoder-Decoder Models for Code Understanding and Generation.

• This model was trained with commit diffs, WITHOUT commit message history.

• This model was trained on the CommitChronicle dataset introduced in our study.

• Our hyperparameter setting is mostly based on 📜 RACE: Retrieval-augmented Commit Message Generation. The exact values are provided below:

  Hyperparameter	Value
  Encoder context max length	512
  Decoder context max length	512
  Number of training epochs	1
  Batch size	32
  Optimizer	AdamW
  Warmup	Linear
  Number of warmup steps	100
  Peak learning rate	0.00002
