> The dataset it was trained on was 2770 images, minus 982 of those used for validation. I don't think you got that 2770 correct. Might be 9250 images, minus 982 (that one you got right). Then again, the paper is so badly written, I find it difficult to decipher what they did. From section 3.1: Briefly, NSD provides data acquired from a 7-Tesla fMRI scanner over 30–40 sessions during which each subject viewed three repetitions of 10,000 images. We analyzed data for four of the eight subjects who completed all imaging sessions (subj01, subj02, subj05, and subj07). We used 27,750 trials from NSD for each subject (2,250 trials out of the total 30,000 trials were not publicly released by NSD). For a subset of those trials (N=2,770 trials), 982 images
were viewed by all four subjects. Those trials were used as the test dataset, while the remaining trials (N=24,980) were used as the training dataset. https://www.biorxiv.org/content/10.1101/2022.11.18.517004v2.... |
