Abstract
A method for generating adversarial attacks on a video recognition model is disclosed, including (a) generating the content of bullet-screen comments (BSCs) by an image captioning model for a clean video sample; (b) generating an adversarial video sample by inserting the BSCs into the clean video sample; (c) using the adversarial video sample to attack the video recognition model; (d) receiving rewards from the environment; (e) optimizing the position and transparency of BSCs by an reinforced learning (RL) agent according to the received rewards; (f) updating the adversarial video sample and using it to attack the video recognition model; and iteratively repeating steps of (d)-(f), until a predefined condition is matched.
