  1. A Closed-form Solution to Photorealistic Image StylizationExperimental results show that the stylized photos generated by our algorithm are twice more preferred by human subjects in average. Moreover, our method runs 60 times faster than the state-of-the-art approach. Code available. (via Ming-Yu Liu)
  2. Characterizing Social Media Messages by How They Propagate Since content information is sparse and noisy on social media, adopting TraceMiner allows you to provide a high degree of classication accuracy even in the absence of content information. Experimental results on real-world data sets show the superiority over state-of-the-art approaches on the task of fake news detection and news categorization. (via Paper a Day)

  4. GitLeakssearches full repo history for secrets and keys.
  5. Obfuscated GradientsIn our recent paper, we evaluate the robustness of eight papers accepted to ICLR 2018 as non-certified white-box-secure defenses to adversarial examples. We find that seven of the eight defenses provide a limited increase in robustness and can be broken by improved attack techniques we develop. It’s very easy to make an image that looks to a human like one thing, but which a deep learning classifier will identify as something else. (via Dan Kaminsky)
