NSFW Image Classification

At the end of last month, Yahoo opened the sources of training a model to classify not suitable/safe for work (NSFW) images, particularly pornographic images, using convolutional neural network (CNN). It was implemented with Caffe. Users need to supply the training data, positive being the NSFW images, and negative being the suitable/safe for work (SFW) images, to train the model. The model takes an image as the input, and output a score between 0 and 1.

The codes are available on Github, with the README.md about the installation.
