Sometimes when I'm searching online for something hard to pin down in words, I click over to the Image results. Images let me quickly scan for nuances of a concept, and from there, I can identify the sites that might offer exactly what I'm looking for.<br>
<br><br>
I was reminded of this today reading about 'STAMINA'—<em><strong>STA</strong>tic <strong>M</strong>alware-as-<strong>I</strong>mage <strong>N</strong>etwork <strong>A</strong>nalysis</em>. Artificial intelligence applications are getting very good at learning from images, so Intel and Microsoft are exploring a way to convert binary computer code into grayscale pictures. Their A.I. can then scan the images for patterns, and in this way, identify malware with increased accuracy.
