Outline Colorization through Tandem Adversarial Networks

When creating digital art, coloring and shading are often time consuming tasks that follow the same general patterns. A solution to automatically colorize raw line art would have many practical applications. We propose a setup utilizing two networks in tandem: a color prediction network based only on outlines, and a shading network conditioned on both outlines and a color scheme. We present processing methods to limit information passed in the color scheme, improving generalization. Finally, we demonstrate natural-looking results when colorizing outlines from scratch, as well as from a messy, user-defined color scheme.

Speeding Up TRPO Through Parallelization and Parameter Adaptation

I never actually finished a paper for this, but there is an old draft at http://kvfrans.com/static/trpo.pdf. These slides from a talk I gave during my OpenAI interview are more up-to-date.
