arXiv:2412.08147v2 Announce Type: replace-cross Abstract: Pareto fronts are useful to find good task-mixing strategies for multitask finetuning, but they are also costly to compute. To reduce costs, recent works have used existing model merging methods to help train cheap surrogate models to estimate the Pareto fronts. However, no work has yet considered designing new model-merging methods to directly, and provably, improve the quality of Pareto fronts. Here, we fill this gap by proposing a new Bayesian approach called Variational Model Merging. In this approach, existing model-merging methods
The increasing complexity and computational cost of multitask AI models necessitate more efficient finetuning methods to achieve optimal performance without prohibitive resource expenditure.
This development offers a more efficient and provably better approach to finetuning multitask AI models, potentially accelerating AI development and reducing the computational burden associated with complex AI systems.
A new Bayesian method for model merging can directly improve the quality of Pareto fronts in multitask finetuning, making the optimization of complex AI systems more robust and cost-effective.
