  • Creativity: How original and innovative is the product? Is there already an existing model or software application with similar functionality? Does this project integrate deep learning in an innovative, unexpected way?
  • Technical Complexity: Does the product integrate a large number of components? Is it widely useful, and scalable? Is the software application or model usable in a production setting?
  • Social Impact: What kind of social or business value could this product deliver? How does this software application use deep learning to make the world a little bit better, and to positively impact people’s lives?


Judges will evaluate and attribute a score to each Solution made up of scores based upon the above-listed criteria. The entries that receive the highest overall scores will be selected as the potential winner(s). In the event of a tie, the Solution(s) that received the higher scores from the Judges in the categories of creativity, technical complexity, and social impact will be selected as one of the potential winner(s).  In the event a potential winner is disqualified for any reason, the Solution that received the next highest total score will be chosen as the potential winner

On or about May 9, 2019, the potential winners will be selected and notified by telephone and/or email, at Sponsor’s discretion.

With respect to notification by telephone, such notification will be deemed given when the potential winner engages in a live conversation with Sponsor or when a message is left on the potential winner’s voicemail service or answering machine by the Sponsor, whichever occurs first.
