While generative models, i.e., variational autoencoders or autoregressive models have proved their effectiveness in handling spatio-temporal data, utilizing them in 360° VSP is still challenging due to the problem of severe distortion and feature alignment inconsistency. In this study, we propose a novel spatio-temporal consistency generative network for 360° VSP. A dual-stream encoder-decoder architecture is adopted to process the forward and backward frame sequences of 360° videos simultaneously. Moreover, a deep autoregressive module termed as axial-attention based spherical ConvLSTM is designed in the encoder to memorize features with global-range spatial and temporal dependencies. Finally, motivated by the bias phenomenon in human viewing behavior, a temporal-convolutional Gaussian prior module is introduced to further improve the accuracy of the saliency prediction. Extensive experiments are conducted to evaluate our model and the state-of-the-art competitors, demonstrating that our model has achieved the best performance on the databases of PVS-HM and VR-Eyetracking.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"14 2","pages":"311-322"},"PeriodicalIF":3.7,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140171922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since its advent about a decade ago, JETCAS has published quarterly special issues on emerging and selected topics that cover the entire field of interest of the CASS. Particular emphasis has been put on emerging areas that are expected to grow over time in scientific and professional importance. For example, the special issues published in the last two years touched upon industry x.0 applications, unconventional computing techniques, memristive circuits and systems, quantum computation, processing-in-memory machine learning, and highly renewable penetrated power systems. Some of these special issues have become valuable references in many forefront technology developments within and beyond CASS. Thanks to the strong leadership by Prof. Ho Ching (Herbert) Iu, the outgoing Editor-in-Chief, and the remarkable work of his editorial board, JETCAS is now one of the leading journals in the CASS, with an impact factor of 4.6-5.8 from 2022 to 2023.

However, this approach has two main weaknesses. First, the differences between contexts of different nodes are not significant, making it difficult for the context model to accurately predict the probability distribution of node occupancy. Second, as the one-hot encoding is not the actual probability distribution of node occupancy, the cross-entropy loss function is inaccurate. To address these problems, we propose a general structure that can enhance existing context models. We introduce the context feature residuals into the context model to amplify the differences between contexts. We also add a multi-layer perception branch, that uses the mean squared error between its output and node occupancy as a loss function to provide accurate gradients in backpropagation. We validate our method by showing that it can improve the performance of an octree-based model (OctAttention) and a voxel-based model (VoxelDNN) on the object point cloud datasets MPEG 8i and MVUB, as well as the LiDAR point cloud dataset SemanticKITTI.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"14 2","pages":"224-234"},"PeriodicalIF":3.7,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139949279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the phase noise for the fundamental oscillators, a feedback network containing a long cascaded transmission line featuring high frequency selectivity is proposed. Then, the signal power is extracted through the use of a compact coupled line to drive the doubler, thereby making the integration of a multi-element array more manageable. Furthermore, the strength of the coupling between the two adjacent oscillators within each element is designed properly, yielding dual-band operation to extend the frequency range. Fabricated in a 65-nm bulk CMOS process, the radiator chip assembled with a crystal slab and a silicon lens achieves output frequency ranging from 299.2 to 314.8 GHz. The measured peak effective isotropically radiated power (EIRP) and radiated power are 3.9 and −16.1 dBm, respectively, while consuming 93-mW DC power from a 1.4-V power supply. The phase noise measures −79.9 dBc/Hz at 1-MHz offset from 312 GHz, corresponding to a figure-of-merit (FoM) of 170.1 dBc/Hz.
