&gt; For each image, the algorithm produces a heat map showing which parts of the image are most memorable. By emphasizing different regions, they can potentially increase the image’s memorability.<p>Most memorable, according to human subjects subjective thought on the matter?<p>&gt; The team then pitted its algorithm against human subjects by having the model predicting how memorable a group of people would find a new never-before-seen image. It performed 30 percent better than existing algorithms and was within a few percentage points of the average human performance.<p>Who&#x27;s to say human subjects are any good at objectively judging how memorable a photo is? I feel like I&#x27;m missing something.<p>Edit: Riight, I guess it could be based on observing neural activity in human subjects while they look at photos. That makes a lot more sense.
