ABSTRACT: New generation (5G/6G) mobile networks are evolving, from classical communication infrastructures, to networks supporting and enabling advanced services based on (deep) machine-learning, like augmented reality, autonomous driving, Internet of Things, etc. Edge Machine Learning (EML) is a relatively recent paradigm that allows User Equipments (UEs), connected to a mobile network, to opportunistically offload their computational and learning tasks to Edge Servers (ESs) that are physically close to the Radio Access Network (RAN). The goal of EML is to efficiently manage the system resources, such as transmission power, bandwidth, and computational energy, both at the UEs and ESs, while performing learning tasks with guaranteed accuracy, and within a prescribed latency, for each specific application. This can be done by proper resource management strategies, and the solution of dynamic optimization problems. In a (limited) resource optimization perspective, it is intuitive the UEs should offload to the ESs the (minimum) amount of information that is enough to complete the learning task with the desired accuracy, e.g., to meet the requirements of an user-specific application. This intuitive idea, has been recently formalized under the so called Goal-Oriented (or task-oriented) communications. This lecture provides an introduction to goal-oriented wireless communications for edge-assisted machine learning services, and will show some practical examples, where this framework is exploited to define and dynamically solve optimal resource allocation strategies, whose objective is to flexibly trade energy consumption for learning accuracy, under guaranteed service latency.

ABSTRACT: The goal of this lecture is to introduce the basic tools for processing signals defined over a topological space. Nowadays, processing signals defined over a graph has become a well established technology. Graphs are just an example of topological space, incorporating only pairwise relations. In this lecture, after reviewing the fundamentals of signal processing over graphs, we will introduce simplicial and cell complexes as spaces able to incorporate higher order relations in the representation space, still possessing a rich algebraic structure that facilitates the extraction of information from the data. We will motivate the introduction of a simplicial (or cell) Fourier Transform and we will show how to design filters over a cell complex and to derive sampling strategies. Then we will move to the design of topological neural networks, operating over signals defined over topological spaces of different order, and we will present methods to infer the structure of space from data and to design neural networks operating on data living on a topological space. Finally, we will show a number of applications.

ABSTRACT: Internet-of-Things (IoT) offers an intelligent infrastructure of networked smart devices offering task-specific monitoring and control services. IoT’s unique features include heterogeneity, ubiquitous low-power devices, and unpredictable dynamics also due to human participation. The need naturally arises for foundational innovations in network monitoring and management to allow efficient adaptation to changing environments, and low-cost service provisioning, subject to stringent latency constraints. To this end, the overarching theme of this tutorial is a unifying framework for online monitoring and management for IoT through contemporary communication, networking, learning, and optimization advances. From the network architecture vantage point, the unified framework leverages a promising architecture termed fog that enables smart devices to have proximity access to cloud functionalities at the network edge, along the cloud-to-things continuum. From the algorithmic perspective, key innovations include online approaches based on ensemble Gaussian processes that can offer adaptivity to different degrees of nonstationary in IoT dynamics. Scalability of implementation further motivates bandit operation along with local information exchanges that enable distributed approaches. The outlined framework can serve as a stepping stone that leads to systematic designs and rigorous analysis of task-specific learning and management schemes for IoT.

Abstract: The field of graph signal processing extends classical signal processing tools to signals (data) with an irregular structure that can be characterized by means of a graph (e.g., network data). One of the building blocks of this field are graph filters, direct analogues of time-domain filters, but intended for signals defined on graphs. In this tutorial, we introduce the field of graph signal processing and specifically give an overview of the graph filtering problem. We look at the family of finite impulse response (FIR) and infinite impulse response (IIR) graph filters and show how they can be implemented in a distributed manner. To further limit the communication and computational complexity of such a distributed implementation, we also generalize the state-of-the-art distributed graph filters to filters whose weights show a dependency on the nodes sharing information. These so-called edge-variant graph filters yield significant benefits in terms of filter order reduction and can be used for solving specific distributed optimization problems with an extremely fast convergence. Finally, we will overview how graph filters can be used in deep learning applications involving data sets with an irregular structure. Different types of graph filters can be used in the convolution step of graph convolutional networks leading to different trade-offs in performance and complexity. The numerical results presented in this talk illustrate the potential of graph filters in signal processing and machine learning.

Abstract: To transmit text messages, speeches, or pictures, we usually convert them into a symbol sequence and transmit the symbols in a conventional communication system, which is designed based on the block structure with coding, decoding, modulation, demodulation, etc. It has been demonstrated recently that deep learning (DL) has great potentials to break the bottleneck of the block-based communication system. In this talk, we first provide our recent endeavors in developing end-to-end (E2E) communications, which combine all blocks at the transmitter by a neural network and those at the receiver by another neural network. Even if deep learning based E2E communication systems have a potential to outperform the conventional block-based communication systems in terms of performance and complexity, their spectrum efficiency is still limited by Shannon capacity since they essentially transmit bits or symbols. Semantic communication systems transmit and recover the desired meaning of the transmitted content (for example, a text message or a picture) directly and can significantly improve transmission efficiency. We will present our initial results on semantic communications.

Abstract: Under the assumption that network data are related to the topology of the graph where they are supported, the goal of graph signal processing (GSP) is to develop algorithms that fruitfully leverage this relational structure and can make inferences about these relationships, even when they are only partially observed. Many GSP efforts to date assume that the underlying network is known, and then analyze how the graph’s algebraic and spectral characteristics impact the properties of the graph signals of interest. However, such an assumption is often untenable in practice and arguably most graph construction schemes are largely informal, distinctly lacking an element of validation. In this lecture, we offer an overview of network topology inference methods developed to bridge the aforementioned gap, by using information available from graph signals along with innovative GSP tools and models to infer the underlying graph structure. It will also introduce the attendees to challenges and opportunities for SP research in emerging topic areas at the crossroads of modeling, prediction, and control of complex behavior arising with large-scale networked systems that evolve over time. Accordingly, this lecture stretches all the way from (nowadays rather mature) statistical approaches including correlation analyses to recent GSP advances in a comprehensive and unifying manner. Through rigorous problem formulations and intuitive reasoning, concepts are made accessible to SP researchers not well versed in network-analytic issues. A diverse gamut of network inference challenges and application domains will be selectively covered, based on importance and relevance to SP expertise, as well as the instructor's own experience and contributions

Abstract: The stringent, and often extreme, reliability guarantees posed for ultra-reliable low-latency communications (URLLC) can be attained and claimed in a credible way only by relying on a proper statistical characterization and statistical learning. This characterization should justify the claim that a user will be guaranteed a reliability of, say, 99.999 %, given the observed data on the wireless channel as well as any other prior knowledge. This lecture presents the statistical aspects of URLLC, detailing both frequentist and Bayesian approaches. URLLC has different definitions for reliability, availability, latency, etc., depending on which communication layers are included. The lecture focuses on the physical layer since it is fundamental to the understanding of the overall performance. It presents the statistical features and guarantees for outage probability in a narrowband wireless channel. Outage can occur when the instantaneous channel quality cannot support the data rate selected by the transmitter. For the frequentist approach, there is a need for excessive number of observations required to characterize ultra-rare events. The required number of observations can be decreased by using prior knowledge, which brings in the Bayesian method. As a motivating example, we treat the practical case in which a base station (BS) collects spatial channel statistics for users at different locations and attempts to predict the performance of a user at a new location. The lecture will discuss how this case can be addressed by using statistical characterization of radio maps. An example will be presented based on a synthetic dataset generated by ray-tracing, where the BS can obtain high-quality predictions of the reliability performance even for locations that are not in proximity.

Abstract: The operation of CNNs from the matched filter perspective will be explained, and it will be shown that their very backbone – the convolution operation – represents a matched filter which examines the input for the presence of characteristic patterns in data. This fact serves as a vehicle for a unifying account on the overall functionality of CNNs, whereby the convolution-activation-pooling chain and learning strategies are also shown to admit a compact and elegant interpretation under the umbrella of matched filtering. Then, a review of graphs, as a basis for a signal and signal processing on irregular domain will be given. Graph Convolutional Neural Networks (GCNN) are becoming a model of choice for learning on irregular domains; yet due to the black-box nature of neural networks (NNs) their underlying principles are rarely examined in depth. To this end, we revisit the operation of GCNNs and show that the convolutional layer effectively performs, as in the standard CNN, graph matched filtering of its inputs with a set of predefined patterns (features). We then show how this serves as a basis for an analogous framework for understanding GCNNs which maintains physical relevance throughout the information flow, including nonlinear activations and max-pooling. Such an approach is shown to be quite general, and yields both standard CNNs and fully connected NNs as special cases. For enhanced intuition, a step-by-step numerical example is provided through which the information propagation through GCNNs is visualised, illuminating all stages of GCNN operation and learning.

Abstract: Learning the statistics of physical phenomena has been a long-time research objective. The advent of machine learning methods has offered effective tools to tackle such an objective in several data science domains. Some of those tools can be used in the domain of communication systems and networks. We should, however, distinguish between data learning from signal learning. The former paradigm is typically applied to higher protocol layers, while the latter to the physical layer. Historically, stochastic models derived from the laws of physics have been exploited to describe the physical layer. From these models, transmission technology has been developed and performance analysis carried out. Nevertheless, this approach has shown some shortcomings in complex and uncertain environments. Based on these preliminary considerations, we will review basic concepts about the statistical description of random processes and conventional random signal generation methods. Then, recent generative models capable of firstly learning the hidden/implicit distribution and then generating synthetic signals will be discussed. We will review the concept of copula and motivate the use of recently introduced segmented neural network architectures that operate in the uniform probability space. The application of such generative models to classic (but still open) problems in communications will be illustrated, including: synthetic channel and noise modeling, channel capacity estimation, coding/decoding design in unknown channels. A key enabler component is the ability to estimate mutual information. This will lead us to the description of novel estimators and their application to learning the channel capacity, which is an ambitious goal being capacity mostly unknown even for channels analytically described. More constructively, we will show that autoencoders can be used to design capacity approaching coding/decoding schemes. Finally, just focusing at the receiver side, we will present optimal decoding strategies based on deep learning neural architectures. The lecture will substantiate the theoretical aspects with several application examples not only in the wireless communication context but also in the less known power line communication domain; the latter domain being perhaps more challenging giving the extremely complex nature of the channel and noise.

Abstract: In this lecture, we present a tutorial overview of a powerful class of probabilistic graphical models called factor graphs and specialize their model in the large-scale multivariate Gaussian distribution setting. Our focus is on Gaussian Belief Propagation (GBP), a simple, efficient and widely applicable algorithm for probabilistic inference on factor graphs. We discuss the key issues of GBP applied in real-world probabilistic systems, such as correctness, convergence and complexity through the prism of GBP applications in the fundamental problem of state estimation in power systems. Future extensions of these concepts using modern data-based machine (deep) learning tools are also presented as our ongoing work.

Abstract: This is a tremendously fun hands-on course on low-power wireless, where you will be designing, assembling, programming and deploying you very own low-power wireless network. I will be bringing cases full of low-power wireless boards, programming cables, sensors and batterie. Low-power wireless is deeply embedded, and touches upon many technologies, including low-power electronics and wireless. There is no better way of learning about low-power wireless than trying it for real. In lockstep with the “theory” seen through slideware, you will all be playing with state-of-the-art technology. Specifically, we will be using the market leading IoT technology used in industrial application, called SmartMesh, by Analog Devices. A SmartMesh network offers over 99.999% end-to-end requires, with each device consuming less than 50 μA. Each of you will receive a set of SmartMesh devices to apply to a real-world use case. Throughout this hands-on course, you will be able to build a low-power wireless network, attach sensors to it, deploy it, and connect it to the Internet. The module will end with a project in which we will all be building one large sensor-to-cloud solution. This course will be super fun. The instructor is a super enthusiastic IoT professional who is 200% driven to teach you the ropes and build something together. This course will be fulfilling because it allows you to put many different things you have learned to good use: embedded systems, electronics, networking, web programming, etc. This course will be nice challenging in that the entire class will work together in building a complete solution where each element has to work together. This course provides you with a very detailed introduction to low-power wireless, what it is, what it is not, what are the challenges and what are the solutions that exist today. We will put a particular on talking about what low-power wireless “really” is, building up all the material presented from real-world use cases, both from exploratory academic experiments and real-world commercial (and critical) applications.
