What’s that Smell? GNNose Knows!

<p><em>Sniff</em>.&nbsp;<em>Sniff</em>.&nbsp;<em>What&rsquo;s that smell?</em>&nbsp;<em>It&rsquo;s a tangy and pungent aroma that&rsquo;s also&hellip; slightly sour? Is it&hellip; could it be&hellip; yes! It&rsquo;s CH3COOH, or as it&rsquo;s more commonly known, vinegar.</em></p> <p>For over 70 years, scientists at the intersection of chemistry, neuroscience, and (recently) machine learning have investigated how molecular structures of substances affect how they smell to humans. This is a surprisingly difficult task. A small difference can result in completely different flavors, and&nbsp;<a href="https://arxiv.org/abs/1910.10685" rel="noopener ugc nofollow" target="_blank">molecules with drastically different structures can have similar odors</a>&nbsp;[1, 4]. Recent advances in deep learning have enabled progress on this problem via ResNets, GNNs, and other architectures.</p> <p><a href="https://medium.com/stanford-cs224w/whats-that-smell-gnnose-knows-1770d9123c05"><strong>Click Here</strong></a></p>
