NVIDIA has released a guide for fine-tuning its Cosmos Predict 2.5 world model for robot video generation using parameter-efficient techniques like LoRA and DoRA. This method allows for adaptation to specific domains, such as robot manipulation, without the high cost and risk of catastrophic forgetting associated with full fine-tuning. The process involves using libraries like diffusers and accelerate to train on smaller datasets, enabling the generation of synthetic robot trajectories for downstream learning tasks. Separately, researchers have introduced ShadowPEFT, a novel centralized framework for parameter-efficient fine-tuning that uses a depth-shared shadow module for layer-level refinement, showing competitive or superior performance to LoRA and DoRA on various benchmarks.
