01 Oct 2019TL;DR: This work develops a novel hierarchical point sets learning architecture that gradually agglomerates points by stacking this learnable and lightweight module based on graph convolution network, and proposes a parameter sharing scheme for reducing memory usage and computational burden induced by the agglomersation module.
Abstract: Many previous works on point sets learning achieve excellent performance with hierarchical architecture. Their strategies towards points agglomeration, however, only perform points sampling and grouping in original Euclidean space in a fixed way. These heuristic and task-irrelevant strategies severely limit their ability to adapt to more varied scenarios. To this end, we develop a novel hierarchical point sets learning architecture, with dynamic points agglomeration. By exploiting the relation of points in semantic space, a module based on graph convolution network is designed to learn a soft points cluster agglomeration. We construct a hierarchical architecture that gradually agglomerates points by stacking this learnable and lightweight module. In contrast to fixed points agglomeration strategy, our method can handle more diverse situations robustly and efficiently. Moreover, we propose a parameter sharing scheme for reducing memory usage and computational burden induced by the agglomeration module. Extensive experimental results on several point cloud analytic tasks, including classification and segmentation, well demonstrate the superior performance of our dynamic hierarchical learning framework over current state-of-the-art methods.

22 Aug 2008TL;DR: In this article, a presence service system using the presence service access device, comprising of a presentity, a presence server, and a watcher client, is presented, where the presence server distributes the presence information to the corresponding watcher.
Abstract: A presence service access device is disclosed for a presentity to publish presence information and transmit said information to the presence server, the device comprising a presentity communication module and a service scheduling control module. Further disclosed is a presence service system using the presence service access device, comprising a presentity, a presence service access device, a presence server, and a watcher client. Also disclosed is a method of publishing and acquiring presence information comprising steps of: 1. a presentity which publishes presence information; 2. the presence service access device which receives the presence information published by the presentity and forwards the same to a presence server; and 3. the presence server which distributes the presence information to corresponding watcher client. According to the present invention, various presentities provide presence information to watcher clients by connecting presence servers through a presence service access device.

TL;DR: The initial results show that, from a technical perspective, spectrum pooling at mmWave has the potential to use the resources more efficiently than traditional exclusive spectrum allocation to a single operator.
Abstract: Motivated by the specific characteristics of mmWave technologies, we discuss the possibility of an authorization regime that allows spectrum sharing between multiple operators, also referred to as ...

TL;DR: This paper introduces an effective receiver for the LDS-OFDM scheme, and proposes a framework to analyze and design this iterative receiver using extrinsic information transfer (EXIT) charts, and shows how the turbo MUDD is tuned using EXIT charts analysis.
Abstract: Low density signature orthogonal frequency division multiplexing (LDS-OFDM) is an uplink multi-carrier multiple access scheme that uses low density signatures (LDS) for spreading the symbols in the frequency domain. In this paper, we introduce an effective receiver for the LDS-OFDM scheme. We propose a framework to analyze and design this iterative receiver using extrinsic information transfer (EXIT) charts. Furthermore, a turbo multi-user detector/decoder (MUDD) is proposed for the LDS-OFDM receiver. We show how the turbo MUDD is tuned using EXIT charts analysis. By tuning the turbo-style processing, the turbo MUDD can approach the performance of optimum MUDD with a smaller number of inner iterations. Using the suggested design guidelines in this paper, we show that the proposed structure brings about 2.3 dB performance improvement at a bit error rate (BER) equal to 10-5 over conventional LDS-OFDM while keeping the complexity affordable. Simulations for different scenarios also show that the LDS-OFDM outperforms similar well-known multiple access techniques such as multi-carrier code division multiple access (MC-CDMA) and group-orthogonal MC-CDMA.

TL;DR: In this article, a multiphase transmission scheme was proposed for the K-user single-input single-output (SISO) additive white Gaussian noise (AWGN) interference channel and 2×K SISO AWGN X channel, where the transmitters have delayed channel state information (CSI) through noiseless feedback links.
Abstract: The K-user single-input single-output (SISO) additive white Gaussian noise (AWGN) interference channel and 2×K SISO AWGN X channel are considered, where the transmitters have delayed channel state information (CSI) through noiseless feedback links. Multiphase transmission schemes are proposed for both channels which possess novel ingredients, namely, multiphase partial interference nulling, distributed interference management via user scheduling, and distributed higher order symbol generation. The achieved degree-of-freedom (DoF) values are greater than the best previously known DoFs for both channels with delayed CSI at the transmitters.
