Congress s deepening interest in deepfakes

© iStock Congress is closing the year by taking significant yet unheralded early steps to legislate on “deepfakes,” false yet highly realistic artificial intelligence (AI)-created media like a recent satirical video of President Trump In quick succession in December, Congress sent two bills to the president, the National Defense Authorization (NDAA) for FY 2021 and the IOGAN Act. They would require, respectively, the Department of Homeland Security (DHS), the Department of Defense (DOD), and the National Science Foundation (NSF) to issue reports on and bolster research into deepfakes, which are sometimes known by other names like “machine-manipulated media,” “synthetic media,” or “digital content forgeries.” These bills ask for recommendations that could lay the predicate for federal regulations of such media. 

Efficient AutoGAN: Predicting the rewards in reinforcement-based neura by Yi Fan, Xiulian Tang et al

Publication Details Fan, Y., Tang, X., Zhou, G. & Shen, J. (2020). Efficient AutoGAN: Predicting the rewards in reinforcement-based neural architecture search for Generative Adversarial Networks. IEEE Transactions on Cognitive and Developmental Systems, online first 1-13. Abstract This paper is inspired by human’s memory and recognition process to improve Neural Architecture Search (NAS), which has shown novelty and significance in the design of Generative Adversarial Networks (GAN), but the extremely enormous time consumption for searching GAN architectures based on reinforcement learning (RL) limits its applicability to a great extent. The main reason behind the challenge is that, the performance evaluation of sub-networks during the search process takes too much time. To solve this problem, we propose a new algorithm, EfficientAutoGAN, in which a Graph Convolution Network (GCN) predictor is introduced to predict the performance of sub-networks instead of formally assessing or

Jarolim et al. / Astronomy&Astrophysics Scientists from the University of Graz and the Kanzelhöhe Solar Observatory (Austria) and their colleagues from the Skolkovo Institute of Science and Technology (Skoltech) developed a new method based on deep learning for stable classification and quantification of image quality in ground-based full-disk solar images. The research results were published in the journal Astronomy & Astrophysics and are available in open access.
