What exactly is the purpose of logging the weight distributions like this?

It's supposed to be an extra diagnostic to catch things like some weights exploding or gradients vanishing. I added it to compare embedding distributions between regular and context nodes. |

Ah, okay. Definitely makes sense as a diagnostic tool for that. And I guess the size increase isn't large because it's just a histogram over each layer. |

LGTM, but it's probably good to wait for Ondrej's approval as well.
