Whether one person's subjective experience of the "redness" of red is equivalent to another's is a fundamental question in consciousness studies. Intersubjective comparison of the relational structures of sensory experiences, termed "qualia structures", can constrain the question. We propose an unsupervised alignment method, based on optimal transport, to find the optimal mapping between the...

Previously, this claim has been examined by studies that manipulated attention and characterized conscious perception in binary categorical labels (e.g. seen versus unseen). However, these categorical judgments are not powerful enough to characterize the quality of...
