Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support compression of channel information (e.g., channel feedback) in accordance with multiple compression schemes, from which a transmitting device may select for a channel reporting transmission. For example, a user equipment (UE) may be configured with multiple channel state information compression schemes, corresponding to different encoders or decoders, which may involve various machine learning or neural network techniques. The UE may select or otherwise determine which compression scheme to use for channel reporting in various scenarios, including a selection based on whether a compression scheme maintains relatively accurate reporting, or whether a more power-intensive or processor-intensive compression scheme is supported by an operating mode of the UE, among other selection criteria.

Abstract: Digital holography is one of the most widely used label-free microscopy techniques in biomedical imaging. Recovery of the missing phase information of a hologram is an important step in holographic image reconstruction. A convolutional recurrent neural network (RNN)-based phase recovery approach is employed that uses multiple holograms, captured at different sample-to-sensor distances to rapidly reconstruct the phase and amplitude information of a sample, while also performing autofocusing through the same trained neural network. The success of this deep learning-enabled holography method is demonstrated by imaging microscopic features of human tissue samples and Papanicolaou (Pap) smears. These results constitute the first demonstration of the use of recurrent neural networks for holographic imaging and phase recovery, and compared with existing methods, the presented approach improves the reconstructed image quality, while also increasing the depth-of-field and inference speed.
