An error-driven framework for tuning large multimodal models identifies specific capability gaps by analyzing model errors on a small validation set, then retrieves targeted training samples from broad datasets. This approach effectively adapts LMMs to new tasks, achieving competitive or superior performance with a fraction of the data compared to full dataset tuning.
Key insights
- Adapting LMMs to new tasks can be efficiently guided by an error-driven approach that mimics human "gap detection and filling."
- Precisely identifying and addressing specific underlying capability gaps in an LMM through detailed error analysis leads to more effective and targeted tuning than surface-level data selection or random sampling.
- Untargeted fine-tuning on vast datasets can introduce "task interference," suggesting that a smaller, precisely selected dataset can yield superior or comparable performance.
