  • Publication number: 20210241099
    Abstract: Generative adversarial models have several benefits; however, due to mode collapse, these generators face a quality-diversity trade-off (i.e., the generator models sacrifice generation diversity for increased generation quality). Presented herein are embodiments that improve the performance of adversarial content generation by decelerating mode collapse. In one or more embodiments, a cooperative training paradigm is employed where a second model is cooperatively trained with the generator and helps efficiently shape the data distribution of the generator against mode collapse. Moreover, embodiments of a meta learning mechanism may be used, where the cooperative update to the generator serves as a high-level meta task and which helps ensures the generator parameters after the adversarial update stay resistant against mode collapse. In experiments, tested employments demonstrated efficient slowdown of mode collapse for the adversarial text generators.

  • Patent number: 11076358
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify one or more first user equipments (UEs) that have been configured for grant-free transmissions on an allocation of resources. In some cases, the base station may then schedule an uplink transmission for a second UE on resources that overlap the allocation of resources. Accordingly, the base station may transmit a power adjustment indication (PAI) to the one or more first UEs to adjust a transmit power for uplink transmissions on the overlapping resources. In some cases, the PAI may include an indication of frequency-domain resources for the power adjustment indicated in the PAI, a specified time duration for the power adjustment indicated in the PAI, an indication of specific uplink transmissions to which the transmit power adjustment is to be applied, or a combination thereof.
