If we do discover a theory of everything … it would be the ultimate triumph of human reason-for then we would truly know the mind of God

Outline of the DeepFace architecture. A front-end of a single convolution-pooling-convolution filtering on the rectified input, followed by three locally-connected layers and two fully-connected layers. Color illustrates feature maps produced at each layer. The net includes more than 120 million parameters, where more than 95% come from the local and fully connected.

A chance for us to acknowledge our ignorance and to rediscover interdisplinary science.

One thing is I can live with is doubt, and uncertainty and not knowing. I think it’s much more interesting to live with not knowing than to have an answer that might be wrong.
