Researchers have developed a new adapter called RPA (Residual Patch-Token Adapter) designed to improve image retrieval from electroencephalography (EEG) and magnetoencephalography (MEG) brain signals. This adapter works by utilizing all patch tokens from intermediate layers of a Vision Transformer (ViT) encoder, preserving richer visual information compared to methods that use only a single global embedding. Experiments show that retaining all patch tokens is crucial for EEG alignment, while the CLS token offers minimal unique information. The RPA system achieves state-of-the-art performance on the THINGS-EEG2 and THINGS-MEG datasets, demonstrating its effectiveness in aligning brain signals with visual features like color and texture.
