Visualized: Where 5G Will Change The World

#artificialintelligence

Whereas 4G brought us the network speeds necessary for online apps and mobile-streaming, 5G represents a monumental leap forward. Beyond the improvements to our existing ecosystem of devices--more speed and better stability--researchers believe that 5G can serve as the underpinning for fully-connected industries and cities. Change doesn't happen overnight, and for us to experience 5G's true potential, we'll need to be patient. In light of this, today's infographic from Raconteur visualizes the forecasted impact of 5G to help us identify the countries and industries that will most effectively leverage its power. To make this easier to digest, here are the five industries which stand to benefit the most.


Sparse Optimization for Green Edge AI Inference

arXiv.org Artificial Intelligence

With the rapid upsurge of deep learning tasks at the network edge, effective edge artificial intelligence (AI) inference becomes critical to provide low-latency intelligent services for mobile users via leveraging the edge computing capability. In such scenarios, energy efficiency becomes a primary concern. In this paper, we present a joint inference task selection and downlink beamforming strategy to achieve energy-efficient edge AI inference through minimizing the overall power consumption consisting of both computation and transmission power consumption, yielding a mixed combinatorial optimization problem. By exploiting the inherent connections between the set of task selection and group sparsity structural transmit beamforming vector, we reformulate the optimization as a group sparse beamforming problem. To solve this challenging problem, we propose a log-sum function based three-stage approach. By adopting the log-sum function to enhance the group sparsity, a proximal iteratively reweighted algorithm is developed. Furthermore, we establish the global convergence analysis and provide the ergodic worst-case convergence rate for this algorithm. Simulation results will demonstrate the effectiveness of the proposed approach for improving energy efficiency in edge AI inference systems.


Sentiment Analysis Exposed

I made it with Max last night! OMG! Welcome to womanhood!! How was it/he? And right about now, Mary's mom gets a'notification' on her cell phone that her daughter is texting sexual references, then displays Mary's texts with Shelly upon mom's request. Mom spends the rest of the day at work fuming, conjuring dialog with her daughter for later that evening when they'll be home together. Never did, and she'd told Mary not to see him.


AI in networking helps keep systems running

#artificialintelligence

In the IT field, where there's an abundance of data, the role of data science is crucial, as it provides insights from this data. Automating the data analysis enables network operators to more effectively identify and study patterns related to how the networks are being used, failures, outages and congestion-related issues, much as data scientists currently do with big data. While there is a widespread shortage of data scientists, adding data science capabilities to network and IT tools provides needed capabilities without requiring more data science talent. IT professionals are using machine learning to craft AI systems that acquire the most relevant information and speed up the process of studying data. IT operations analytics, or ITOA, is an emerging approach to using big data and machine learning to optimize IT operations.


Global Big Data Conference

#artificialintelligence

Many companies are scrambling to find machine learning engineers who can build smart applications that run on edge devices, like mobile phones. One company that's attacking the problem in a broad way is Qeexo, which sells an AutoML platform for building and deploying ML applications to microcontrollers without writing a line of code. Qeexo emerged from Carnegie Mellon University in 2012, just at the dawn of the big data age. According to Sang Won Lee, the company's co-founder and CEO, the original plan called for Qeexo to be a machine learning application company. The company landed a big fish, the Chinese mobile phone manufacturer Huawei, right out the gate.


Deep Reinforcement Learning for QoS-Constrained Resource Allocation in Multiservice Networks

arXiv.org Machine Learning

In this article, we study a Radio Resource Allocation (RRA) that was formulated as a non-convex optimization problem whose main aim is to maximize the spectral efficiency subject to satisfaction guarantees in multiservice wireless systems. This problem has already been previously investigated in the literature and efficient heuristics have been proposed. However, in order to assess the performance of Machine Learning (ML) algorithms when solving optimization problems in the context of RRA, we revisit that problem and propose a solution based on a Reinforcement Learning (RL) framework. Specifically, a distributed optimization method based on multi-agent deep RL is developed, where each agent makes its decisions to find a policy by interacting with the local environment, until reaching convergence. Thus, this article focuses on an application of RL and our main proposal consists in a new deep RL based approach to jointly deal with RRA, satisfaction guarantees and Quality of Service (QoS) constraints in multiservice celular networks. Lastly, through computational simulations we compare the state-of-art solutions of the literature with our proposal and we show a near optimal performance of the latter in terms of throughput and outage rate.


Learning-Based Link Scheduling in Millimeter-wave Multi-connectivity Scenarios

arXiv.org Machine Learning

Multi-connectivity is emerging as a promising solution to provide reliable communications and seamless connectivity for the millimeter-wave frequency range. Due to the blockage sensitivity at such high frequencies, connectivity with multiple cells can drastically increase the network performance in terms of throughput and reliability. However, an inefficient link scheduling, i.e., over and under-provisioning of connections, can lead either to high interference and energy consumption or to unsatisfied user's quality of service (QoS) requirements. In this work, we present a learning-based solution that is able to learn and then to predict the optimal link scheduling to satisfy users' QoS requirements while avoiding communication interruptions. Moreover, we compare the proposed approach with two base line methods and the genie-aided link scheduling that assumes perfect channel knowledge. We show that the learning-based solution approaches the optimum and outperforms the base line methods.


Learning in the Sky: An Efficient 3D Placement of UAVs

arXiv.org Machine Learning

Deployment of unmanned aerial vehicles (UAVs) as aerial base stations can deliver a fast and flexible solution for serving varying traffic demand. In order to adequately benefit of UAVs deployment, their efficient placement is of utmost importance, and requires to intelligently adapt to the environment changes. In this paper, we propose a learning-based mechanism for the three-dimensional deployment of UAVs assisting terrestrial cellular networks in the downlink. The problem is modeled as a non-cooperative game among UAVs in satisfaction form. To solve the game, we utilize a low complexity algorithm, in which unsatisfied UAVs update their locations based on a learning algorithm. Simulation results reveal that the proposed UAV placement algorithm yields significant performance gains up to about 52% and 74% in terms of throughput and the number of dropped users, respectively, compared to an optimized baseline algorithm.

Machine Learning for Predictive Deployment of UAVs with Multiple Access

arXiv.org Machine Learning

In this paper, a machine learning based deployment framework of unmanned aerial vehicles (UAVs) is studied. In the considered model, UAVs are deployed as flying base stations (BS) to offload heavy traffic from ground BSs. Due to time-varying traffic distribution, a long short-term memory (LSTM) based prediction algorithm is introduced to predict the future cellular traffic. To predict the user service distribution, a KEG algorithm, which is a joint K-means and expectation maximization (EM) algorithm based on Gaussian mixture model (GMM), is proposed for determining the service area of each UAV. Based on the predicted traffic, the optimal UAV positions are derived and three multi-access techniques are compared so as to minimize the total transmit power. Simulation results show that the proposed method can reduce up to 24\% of the total power consumption compared to the conventional method without traffic prediction. Besides, rate splitting multiple access (RSMA) has the lower required transmit power compared to frequency domain multiple access (FDMA) and time domain multiple access (TDMA).
