Open release of BVLC model weights

We are releasing the weights for the BVLC-bundled Caffe models

- CaffeNet
- AlexNet
- R-CNN, ILSVRC13
- GoogLeNet

for unrestricted use.

It's come to our attention that "non-commercial use" is not well defined.  Our present understanding as researchers is that UC Berkeley does not feel this restriction is required when releasing the learned weights of our present models, since none of the original images are distributed in whole or in part. As UC Berkeley has published the framework open-source, and non-commercial limitations are considered incompatible with open source principles [1], there is no wish to limit the usage of these BVLC models.

To the extent that a later interpretation arises that weights are derivative works of the original copyright holder and they assert such a copyright, UC Berkeley makes no representations as to what use is allowed other than to consider our present release in the spirit of fair use in the academic mission of the university to disseminate knowledge and tools as broadly as possible without restriction.
