Conditional LoRA Parameter Generation
This work addresses the problem of task-specific adaptation for neural networks, offering a novel approach to parameter generation, though it appears incremental as it builds on existing generative model techniques.
The paper tackles the challenge of generating high-performance neural network parameters using generative models, specifically for LoRA weights, by proposing COND P-DIFF, which employs an autoencoder and conditional latent diffusion to synthesize parameters based on task conditions, achieving consistent high performance in computer vision and natural language processing domains.
Generative models have achieved remarkable success in image, video, and text domains. Inspired by this, researchers have explored utilizing generative models to generate neural network parameters. However, these efforts have been limited by the parameter size and the practicality of generating high-performance parameters. In this paper, we propose COND P-DIFF, a novel approach that demonstrates the feasibility of controllable high-performance parameter generation, particularly for LoRA (Low-Rank Adaptation) weights, during the fine-tuning process. Specifically, we employ an autoencoder to extract efficient latent representations for parameters. We then train a conditional latent diffusion model to synthesize high-performing model parameters from random noise based on specific task conditions. Experimental results in both computer vision and natural language processing domains consistently demonstrate that COND P-DIFF can generate high-performance parameters conditioned on the given task. Moreover, we observe that the parameter distribution generated by COND P-DIFF exhibits differences compared to the distribution obtained through normal optimization methods, indicating a certain level of generalization capability. Our work paves the way for further exploration of condition-driven parameter generation, offering a promising direction for task-specific adaptation of neural networks.
