New LoCA method enhances vision model fine-tuning by decoupling spatial and channel adaptation

Researchers have introduced LoCA (Low-Rank Convolutional Adaptation), a new method for efficiently fine-tuning vision foundation models. Unlike existing LoRA techniques that struggle with the spatial and channel entanglement inherent in convolutional kernels, LoCA decouples these aspects. It employs a low-rank channel adaptation for cross-channel mixing and refines spatial bases using singular value decomposition. Experiments demonstrate LoCA's effectiveness in preserving pre-trained spatial information and achieving competitive or state-of-the-art results in various vision tasks, including classification, semantic segmentation, and generative benchmarks.
