Existing GAN-based generative me.hodsare typically used for semantic image synthesis. Wepose the question of whether GAN-based architecturescan generate plausible depth maps and ﬁnd thatexisting me.hods have difficulty in generating depthmaps which reasonably represent 3D scene structuredue to the lack of global geome.ric ***, we propose DepthGAN, a novel me.hod ofgenerating a depth map using a semantic layout asinput to aid construction, and manipulation of wellstructured 3D scene point clouds. Speciﬁcally, weﬁrst build a feature generation model with a cascadeof semantically-aware transforme. blocks to obtaindepth features with global structural *** our semantically aware transforme. block, wepropose a mixed attention module and a semanticallyaware layer normalization module to better exploitsemantic consistency for depth features ***, we present a novel semantically weighteddepth synthesis module, which generates adaptivedepth intervals for the current scene. We generate theﬁnal depth map by using a weighted combination ofsemantically aware depth weights for different depthranges. In this manner, we obtain a more accuratedepth map. Extensive experime.ts on indoor andoutdoor datasets demonstrate that DepthGAN achievessuperior results both quantitatively and visually for thedepth generation task.

Echo state network(ESN) as a novel artificial neural network has drawn much attention from time.series prediction in edge intelligence. ESN is slightly insufficient in long-term me.ory, thereby impacting the prediction performance. It suffers from a higher computational overhead when deploying on edge devices. We firstly introduce the knowledge distillation into the reservoir structure optimization, and then propose the echo state network based on improved knowledge distillation(ESN-IKD) for edge intelligence to improve the prediction performance and reduce the computational overhead. The model of ESN-IKD is constructed with the classic ESN as a student network, the long and short-term me.ory network as a teacher network, and the ESN with double loop reservoir structure as an assistant network. The student network learns the long-term me.ory capability of the teacher network with the help of the assistant network. The training algorithm of ESN-IKD is proposed to correct the learning direction through the assistant network and eliminate the redundant knowledge through the iterative pruning. It can solve the problems of error learning and redundant learning in the traditional knowledge distillation process. Extensive experime.tal simulation shows that ESN-IKD has a good time.series prediction performance in both long-term and short-term me.ory, and achieves a lower computational overhead.
