Brain-grounding of semantic vectors improves neural decoding of visual stimuli

no code implementations22 Mar 2024 Shirin Vafaei, Ryohei Fukuma, Huixiang Yang, Haruhiko Kishima, Takufumi Yanagisawa

To address this issue, we propose a representation learning framework, termed brain-grounding of semantic vectors, which fine-tunes pretrained feature vectors to better align with the neural representation of visual stimuli in the human brain.

Brain Decoding Representation Learning

Voluntary control of semantic neural representations by imagery with conflicting visual stimulation

The successful control of the feedback images demonstrated that the semantic vector inferred from electrocorticograms became closer to the vector of the imagined category, even while watching images from different categories.
