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...
To what extent are sensory experiences equivalent between individuals? One promising approach to this fundamental question about consciousness is to intersubjectively compare the similarity relationships of sensory experiences, named "qualia structures". Conventional methods for comparing the similarity relationships largely sidestep the issue by assuming experiences evoked by the same stimuli...
Whether one person’s experience of “red” is equivalent to another’s has long been considered unanswerable. One promising approach to this fundamental question about consciousness is the intersubjective comparison of the similarity relations of sensory experiences, termed “qualia structures”. Conventional methods for comparing similarity relations largely sidestep the issue, assuming that...
