Learning Vertex Representations for Bipartite Networks
Gao, Ming, He, Xiangnan, Chen, Leihui, Zhou, Aoying
Recent years have witnessed a widespread increase of interest in network representation learning (NRL). By far most research efforts have focused on NRL for homogeneous networks like social networks where vertices are of the same type, or heterogeneous networks like knowledge graphs where vertices (and/or edges) are of different types. There has been relatively little research dedicated to NRL for bipartite networks. Arguably, generic network embedding methods like node2vec and LINE can also be applied to learn vertex embeddings for bipartite networks by ignoring the vertex type information. However, these methods are suboptimal in doing so, since real-world bipartite networks concern the relationship between two types of entities, which usually exhibit different properties and patterns from other types of network data. For example, E-Commerce recommender systems need to capture the collaborative filtering patterns between customers and products, and search engines need to consider the matching signals between queries and webpages. This work addresses the research gap of learning vertex representations for bipartite networks. We present a new solution BiNE, short for Bipartite Network Embedding}, which accounts for two special properties of bipartite networks: long-tail distribution of vertex degrees and implicit connectivity relations between vertices of the same type. Technically speaking, we make three contributions: (1) We design a biased random walk generator to generate vertex sequences that preserve the long-tail distribution of vertices; (2) We propose a new optimization framework by simultaneously modeling the explicit relations (i.e., observed links) and implicit relations (i.e., unobserved but transitive links); (3) We explore the theoretical foundations of BiNE to shed light on how it works, proving that BiNE can be interpreted as factorizing multiple matrices.
CES 2019: What we learned from the world's biggest tech show
Every year the technology industry gathers in Las Vegas for the Consumer Electronics Show (CES), an event that often sets the agenda for the coming 12 months. This is what CES 2019 taught us. The first 5G networks are expected to begin rolling out this year, and so the next-generation connectivity technology was being mentioned everywhere at CES. Intel, Qualcomm and Samsung all spoke about harnessing the technology to not just offer faster mobile internet speeds, but also to connect more devices and appliances to each other and be able to handle more data in the process. Experts at the show also commented on the higher capacity of 5G networks being able to support the software needed to power networks of driverless cars and robots. The halls of this year's CES hinted at a world where homes, cars and even entire cities are connected to one another, with people able to use these connections to complete tasks every day.

Leaks reveal cloud-based 'Verizon Gaming' service
Verizon probably isn't the first name that'll come to mind when you think of video games, but the carrier apparently has big gaming plans for the future. According to The Verge, the company is working on and is already alpha testing a cloud gaming service à la PlayStation Now called Verizon Gaming. Based on the forum posts and emails The Verge saw, Verizon has been recruiting testers for a while now, giving qualified applicants a free NVIDIA Shield TV, where the service is already up and running with 135 games, and an Xbox One Controller, which works with the platform. Testers also get a $150 Amazon gift card as a reward. Leaked screenshots of the version being tested show popular games like Fortnite, God of War, Detroit Become Human and Red Dead Redemption.
Have a great idea for 5G? Verizon may give you a million dollars to make it happen
Think you've come up with a killer idea for exploiting the emerging next-generation wireless networks known as 5G? If Verizon buys into in your vision and considers it commercially viable, the company will issue you up to a cool $1 million in seed money. What's more, you'll be invited to develop the concept on live networks in one of Verizon's 5G incubator labs, in New York City; Cambridge, Massachusetts; Los Angeles; Palo Alto, California, and Washington, D.C. And Verizon will provide training and technical support to the chosen innovators. It's all part of a "Built on 5G Challenge" launched this week at CES in Las Vegas during a keynote address by Verizon CEO Hans Vestberg.
Enabling FDD Massive MIMO through Deep Learning-based Channel Prediction
Arnold, Maximilian, Dörner, Sebastian, Cammerer, Sebastian, Yan, Sarah, Hoydis, Jakob, Brink, Stephan ten
A major obstacle for widespread deployment of frequency division duplex (FDD)-based Massive multiple-input multipleoutput (MIMO)communications is the large signaling overhead for reporting full downlink (DL) channel state information (CSI) back to the basestation (BS), in order to enable closed-loop precoding. We completely remove this overhead by a deep-learning based channel extrapolation (or "prediction") approach and demonstrate that a neural network (NN) at the BS can infer the DL CSI centered around a frequency f UL; nomore pilot/reporting overhead is needed than with a genuine time division duplex (TDD)-based system. The rationale is that scatterers and the large-scale propagation environment are sufficiently similar to allow a NN to learn about the physical connections and constraints between two neighboring frequency bands, and thus provide a well-operating system even when classic extrapolation methods, like the Wiener filter (used as a baseline for comparison throughout) fails. We study its performance for various state-of-the-art Massive MIMO channel models, and, even more so, evaluate the scheme using actual Massive MIMO channel measurements, rendering it to be practically feasible at negligible loss in spectral efficiency when compared to a genuine TDD-based system. I. INTRODUCTION With a significant increase in area throughput, Massive multiple-input multiple-output (MIMO) antenna communication has become an enabling technology for the upcoming fifth generation (5G) wireless mobile communication systems [1], [2], [3], [4]. However, Massive MIMO systems described in current research literature commonly exploit channel reciprocity and hence rely on time division duplex (TDD)-based approaches [1], i.e., uplink (UL) and downlink (DL) channels share the same frequency band in orthogonal time intervals. Achieving such reciprocity in practice requires accurate hardware with costly calibration circuitry. To mitigate this issue, various alternatives to a full Massive MIMO system have been proposed such as the grid of beams [5] and codebook Massive MIMO [6].
China's Huawei unveils chip for global big data market despite Western security warnings
BEIJING - Huawei Technologies Ltd. showed off a new processor chip for data centers and cloud computing Monday, expanding into new and growing markets despite Western warnings the company might be a security risk. Huawei and other Chinese technology companies that rely on Western technology are stepping up efforts to develop their own. The company based in southern China's Shenzhen has pushed ahead with commercial initiatives despite the Dec. 1 arrest of its chief financial officer, Meng Wanzhou, the daughter of Huawei founder Ren Zhengfei, in Canada on U.S. charges related to possible violations of trade sanctions on Iran. Huawei said the Kunpeng 920 chip is designed for servers that handle a flood of data from smartphones, video and other network services -- a fast growing sector with the development of artificial intelligence and the "internet of things." The company said it is part of a planned product lineup to support "intelligent computing."
How We're Helping to Bridge the ICT Talent Gap
They say that a society thrives only when older generations plant the seeds of trees whose shade they may never enjoy. Through university partnerships and outreach, 4,725 students from 108 nations had completed the program as of year-end 2018. In this post, I talk about why we run the Seeds for the Future program. The current acute shortage of tech talent, especially data scientists and AI experts, is exacerbated by the barriers that prevent many women from fully contributing to the global economy. Together, they are dual bottlenecks hindering ICT development.
