A new arXiv paper investigates domain balancing techniques for multi-domain meeting summarization. Researchers fine-tuned the Mistral-7B model using QLoRA on five English meeting corpora, comparing balanced and natural token distributions at various data volumes. The study found that balancing token distribution improves performance on data-scarce domains with minimal impact on data-rich ones, especially when minority domains are important. Additionally, pruning low-value transcript lines removed approximately 15% of tokens without affecting quality, and the paper clarifies that token-based balancing differs from example-based balancing.
