Merry New Year, Checkers!  This week, Adam takes the night off while Darren and honorary TRC’er Dallas Card join the Toronto crew in the flesh for another fun and informative show. Darren kicks off the festivities by revisiting the sometimes misunderstood cognitive bias called the Dunning-Kruger Effect. Dallas delves into deep artificial neural networks and debunks some myths around machine learning. Finally, Cristina examines whether the British really deserve the rep of having bad teeth.
