You are encouraged to publicize your results on the class project through the newly-created leaderboard wiki, which you can find here.
The wiki is editable by anybody with a Github account, so feel free to add your results by yourself. Here are the instructions, taken from the wiki:
Use this wiki to publicize your results on the Dogs vs. Cats class project.
Every time you get a better result on the challenge, you can insert an entry to the list below (at the appropriate place please, so that the list stays sorted by test error rate). Make sure to include a link to a blog post detailing how you achieved that result. The format for entries is as follows:
<test error rate> (<train error rate>, <valid error rate>): <short description> (<link to blog post>)
