Sparse Matrices, Deep Learning

From: andrew cooke <andrew@...>

Date: Wed, 8 Jun 2016 10:44:19 -0400 

This article on sparse matrix specific hardware
http://www.nextplatform.com/2016/06/06/former-nasa-exec-brings-stealth-machine-learning-chip-light/
got me to wondering what it was used for.

I think this paper explains things in the intro:
http://www.cv-foundation.org/openaccess/content_cvpr_2015/papers/Liu_Sparse_Convolutional_Neural_2015_CVPR_paper.pdf

Basically, deep learning means thrpwing a lot of data at very deep
networks.  Those networks must have alot of redundnacy.  So if you can
find the sparse equivalent you can save time.

But still, I don't think that would have been obvious 10 years ago.
Maybe the hardware company got a lucky break?
