  How the brain captures the meaning of linguistic stimuli across multiple
views is still a critical open question in neuroscience. Consider three
different views of the concept apartment: (1) picture (WP) presented with the
target word label, (2) sentence (S) using the target word, and (3) word cloud
(WC) containing the target word along with other semantically related words.
Unlike previous efforts, which focus only on single view analysis, in this
paper, we study the effectiveness of brain decoding in a zero-shot cross-view
learning setup. Further, we propose brain decoding in the novel context of
cross-view-translation tasks like image captioning (IC), image tagging (IT),
keyword extraction (KE), and sentence formation (SF). Using extensive
experiments, we demonstrate that cross-view zero-shot brain decoding is
practical leading to ~0.68 average pairwise accuracy across view pairs. Also,
the decoded representations are sufficiently detailed to enable high accuracy
for cross-view-translation tasks with following pairwise accuracy: IC (78.0),
IT (83.0), KE (83.7) and SF (74.5). Analysis of the contribution of different
brain networks reveals exciting cognitive insights: (1) A high percentage of
visual voxels are involved in image captioning and image tagging tasks, and a
high percentage of language voxels are involved in the sentence formation and
keyword extraction tasks. (2) Zero-shot accuracy of the model trained on S view
and tested on WC view is better than same-view accuracy of the model trained
and tested on WC view.
