First of all thanks so much for the interest in SReC! It was a pleasant surprise seeing my research on top of Hacker News. Answering a few questions from reading the comments: How is this lossless? The entropy coder is what makes this technique lossless. The neural network predicts a probability distribution over pixels, and the entropy coder can find a near optimal mapping of pixel values to bits based on those probabilities (near optimal according to Shannon’s entropy). On practicality of the method, I don’t expect SReC to replace PNGs anytime soon. The current…</p><p><a href="https://hackerpaper.kaipfister.de/p/2004.02872/">Paper and discussion history</a>.
