Tutorial 1

Title: Embodied Audition for Robots



The success of natural intuitive human-robot interaction (HRI) in the future will critically depend on the responsiveness of the robot to all forms of human expressions as well as the robot’s awareness of the environment. Speech is the most effective means of communication among humans. Furthermore, acoustic signals distinctively characterize physical environments. Truly humanoid robots should therefore extract and constructively exploit auditory information from their environment for communication as well as acoustic scene analysis as much as humans do. While vision-based HRI is well developed, current limitations in robot audition do not allow for an effective, natural human-robot communication in real-world environments. These limitations are mainly due to the severe degradation of the desired acoustic signals by noise, interference and reverberation when captured by the robot’s microphones. 
Natural HRI hinges on the development of effective approaches for robot audition. This tutorial provides an overview and details the challenges, concepts, and state of the art developments in embodied audition for robots. Aimed to overcome current limitations in robot audition, algorithmic approaches are presented which aim towards intelligent ‘ears’ with close-to-human (or even better) auditory capabilities. Novel robot-specific microphone arrays and signal processing algorithms are introduced for localization and tracking of multiple sound sources of interest as well as extraction and recognition of the desired signals. It is shown how robot vision can be used to complement and enhance robot audition by fusing the acoustic and visual modalities. Finally, we discuss how the acquired scenario information from audio and audio-visual processing can be combined and fed back to the acoustic interface for auditory scene analysis.

Tutorial 2

Title: Plenoptic Imaging Representation



In recent years, 3D experiences have become more popular, acknowledging that a faithful, transparent and immersive representation of our world requires more than 2D video. In this context, the current visual representation status quo may be understood as providing only efficient multiview video coding solutions for linear, horizontal only parallax camera arrangements, narrow baselines and reduced viewing range. Moreover, current display solutions based on stereoscopic vision only exploit limited depth cues and have inherent accommodation/vergence conflicts. 
The emergence of new 3D cameras and displays and the increasing request for more immersive experiences led to questioning the fundamentals of the vision process, notably the structure of the information in the light impinging on an observer of a scene. These advances and needs led to the so-called plenoptic function which measures the intensity of light seen from any viewpoint/camera centre 3D spatial position (x,y,z), any angular viewing direction (?,?), over time (t) and for each wavelength (?). In this context, new (3D) visual representation models and associated coding solutions are needed to improve the immersion and interaction experiences as provided by some emerging displays to overcome the limitations. However, the novel imaging representations, notably based on the plenoptic function, will require huge amounts of raw data and thus efficient coding is a must.
Nowadays, a plenoptic representation of a visual scene involving full (horizontal and vertical) parallax may be obtained by using two main representation approaches: i) a so-called super multiview video (SMV) approach where multiple, high-density views are acquired using a multi-camera array (or a single camera rig) with a certain (e.g. linear or arc) arrangement; and ii) a so-called plenoptic approach  based on a single integral/holoscopic camera using a lenticular array composed of a large number of micro lenses able to acquire the light information coming from different incident angles. 
Considering the relevance of the novel potential functionalities, both the MPEG (Free-viewpoint TV (FTV) Adhoc group) and JPEG (JPEG PLENO) standardization groups started studying the representation and coding of the new data types associated to plenoptic imaging representations. 
In this context, the main objective of this tutorial is to review and discuss the present and trends on 3D visual data representation, notably the available coding standards and future coding solutions adopting a plenoptic representation framework.
This tutorial is intended for academics, researchers, professionals and post-graduate students with some background in the area of video coding and applications, especially those with interest in learning about recent developments in visual representation research and standardization, notably regarding 3D imaging, light fields and plenoptic imaging representation.

Tutorial 3

Title: Recovering Structured Signals in Noise: Comparison Lemmas and the Performance of Convex Relaxation Methods



In the past couple of decades, non-smooth convex optimization has emerged as a powerful tool for the recovery of structured signals (sparse, low rank, etc.) from possibly) noisy measurements in a variety applications in statistics, signal processing, machine learning, etc. In particular, the advent of compressed sensing has led to a flowering of ideas and methods in this area. While the algorithms (basis
pursuit, LASSO, etc.) are fairly well established, rigorous frameworks for the exact analysis of the performance of such methods is only just emerging.
The goal of this tutorial will be to develop and describe a fairly general theory for how to determine the performance (minimum number of measurements, mean-square-error, etc.) of such methods for certain measurement ensembles (Gaussian, Haar, etc.). This will allow researchers and practitioners to assess the performance of these methods before actual implementation and will allow them to optimally choose parameters such as regularizer coefficients, number of measurements, etc. The theory includes all earlier results as special cases. It builds on an inconspicuous 1962 lemma of Slepian (on comparing Gaussian processes), as well as on a non-trivial generalization due to Gordon in 1988, and introduces concepts
from convex geometry (such as Gaussian widths) in a very natural way. The tutorial will explain all this, and its various implications, in some detail.

Tutorial 4

Title:  Robust Decentralized Decision Making in Wireless Communications



How to set the cursor between centralized and distributed decision making in future wireless network is one of the most debated and fascinating questions these days when it comes to wireless networking. This tutorial feeds this debate by highlighting tools allowing individual devices to interact in a robust manner among each other, for the benefit of the global network. 
Decentralized or "team" decision making refers to an optimization framework whereby several network nodes seek to make a common utility-maximizing decision while only observing a partial/local and noisy version of the global system state (like the propagation channels). This optimization problem differs from conventional centralized optimization problems and opens many new possibilities and interesting problems.
The tutorial topic is rooted in the sound theories of coordination and team decision which are hot topics within the information theoretic, communication theoretic and signal processing theoretic communities
As an introduction, we will show how fundamental limitations of cellular (and more) networks can be addressed via robust decentralized decision making. This includes wide ranging issues such as interference management, MIMO feedback design, Massive MIMO coordination.
As a second part of the tutorial, we will give an introduction to the general fields of coordination and team decision theories. We will present an overview of the different approaches, their main principles, advantages and limitations. This section provides the fundamental tools used in the rest of the tutorial, presented in a didactic manner. Importantly, coordination and team decision theories are transversal topics which are useful to other fields as well (such as artificial intelligence, control and robotics). In particular, the formulation of the optimization problem is very general and can be used to model the distributed coordination of nodes in many different scenarios.
In the third part, we review practical applications of team decision to the problem of wireless network optimization. Considering the most common and practically relevant scenarios (including resource allocation problems such as power control, scheduling, and beamforming), we show how important gains can be realized and how the obstacles initially formulated can be overcome. Practical gains for wireless networks are illustrated.

Tutorial 5

Title:    Signal processing methods in Sleep Research 



By occupying nearly a third of human lifespan, sleep constitutes the main activity of the human brain. Numerous recent theories on the function of sleep confirm its beneficial role at multiple physiological levels. Together with physical activity and nutrition, sleep is at the basis of a healthy life. Despite the importance of sleep, latest trends show that our society has been progressively curtailing sleep in benefit of other activities. 
The realization of the fact that we may not be getting enough sleep, has motivated the emergence of numerous portable (consumer or medical type) devices that measure signals which can provide sleep relevant information for consumers, patients, or physicians.
The types of signals able to provide sleep relevant information are of a large variety including: movement (actigraphy, radar), muscle activity (electromyography EMG), ocular activity (electro-oculography EOG), cardio-respiratory activity (electrocardiogram ECG, breathing effort), electroencephalography (EEG), and photopletismography (PPG). Signal processing plays an important role in the analysis and interpretation of these signals in the context of sleep.
Sleep research poses interesting signal processing challenges. In offline processing, one faces the challenge of the inherent long duration of the recordings and the relatively high sampling rate necessary to capture microevents that are important to understand the function of sleep. In online processing, one faces the challenge of identifying sleep states (for instance REM or NREM stages) in real-time and with a relatively short latency without having the option to consider the overall sleep architecture.
In the first part of this tutorial lecture, the main theories about the function of sleep will be introduced along with a general presentation of sleep science. 
In the second part, the focus will be on signal processing methods supporting sleep research. The analysis of the sleep macro-structure in terms of sleep stages will be presented followed by the analysis of sleep microstructure characterized by events such as spindles and slow-waves. Sleep models (sleep dissipation, circadian model, and sleep inertia) will also be presented. 
To conclude, current trends in sleep research and the signal processing tools to support this research will be presented.

Tutorial 6

Title: Standardization in semantic image annotation and interaction


Contemporary mobile or web-based applications interact with images in various ways. Multiple platforms or applications manipulate the same content. Too often, this leads to frustrating side effects. Annotations may not be retained when an image is moved from one platform to another or metadata might not be processed correctly because a different schema or vocabulary is used. These problems can be avoided by using the right tools and standards. This tutorial will cover three parts in order to provide insights in the domain of semantic image annotations and its interlinking and show how the aforementioned problems can be avoided.
The first part will give a general introduction to linked data and image annotations.  It will survey the main state-of-the-art concepts in the domain of image annotation and indexing. Modern semantic image annotation representations in research will be briefly covered, which include RDF/Ontology as well as XML based approaches. The main focus will be pointed on Linked Media concepts in the domain of images. 
The second part will highlight interoperability issues in image metadata management and introduce standardized solutions. While presenting an overview of different initiatives (JPEG, MPEG, W3C), the main focus will be pointed on the Joint Photographic Experts Group (JPEG, ISO/IEC JTC1/SC29/WG1), which released a new standard on next generation image metadata. The main goal of the standard is to provide a simple and uniform way of annotating JPEG images with metadata compliant to the Linked Data principles. 
The last part of the tutorial will focus on interaction with images and how to take advantage once images are correctly annotated to bridge the gap between image data and semantics. A basic type of interaction with images is image search. Semantic annotations allow language independent search and enriched search by linking with external resources. Usage of standardized query languages and APIs allow distributed search over multiple platforms. Also, the concept of visual search and the relation with automated annotations will be handled. Again, the main focus will be on supporting standards such as JPEG’s JPSearch framework.

Tutorial 7

Title: Signal Processing Tools for Big Data Analytics



We live in an era of data deluge. Pervasive sensors collect massive amounts of information on every bit of our lives, churning out enormous streams of raw data in various formats. Mining information from unprecedented volumes of data promises to limit the spread of epidemics and diseases, identify trends in financial markets, learn the dynamics of emergent social-computational systems and also protect critical infrastructure including the smart grid and the Internet’s backbone network. While Big Data can be definitely perceived as a big blessing, big challenges also arise with large-scale datasets. The sheer volume of data makes it often impossible to run analytics using a central processor and storage, and distributed processing with parallelized multi-processors is preferred while the data themselves are stored in the cloud. As many sources continuously generate data in real time, analytics must often be performed “on-the-fly” and without an opportunity to revisit past entries. Due to their disparate origins, the resultant datasets are often incomplete and include a sizable portion of missing entries. In addition, massive datasets are noisy, prone to outliers and vulnerable to cyber-attacks. These effects are amplified if the acquisition and transportation cost per datum is driven to a minimum. Overall, Big Data present challenges in which resources such as time, space and energy are intertwined in complex ways with data resources. Given these challenges, ample signal processing (SP) opportunities arise. This tutorial seeks to provide an overview of ongoing research in novel models applicable to a wide range of Big Data analytics problems, as well as algorithms and architectures to handle the practical challenges, while revealing fundamental limits and insights on the mathematical trade-offs involved.

Tutorial 8

Title: Engineering Wireless Full-duplex Nodes and Networks.



A full-duplex wireless transceiver node can transmit and receive at the same time and in the same frequency band. In contrast, a half-duplex wireless transceiver node cannot realize simultaneous bidirectional in-band communication. Consequently, networks where all or some of the nodes are full-duplex capable can potentially achieve higher spectral efficiency than networks where all the nodes are half-duplex. This is the main motivation for the deployment of full-duplex nodes. However, implementing full-duplex capable transceivers requires the mitigation of the self-interference signal, with a power level several orders of magnitude larger than the received power of the signal of interest coming from a distant node. Recently, different research groups have demonstrated the feasibility of substantial self-interference mitigation that enables the realization of full-duplex communications with higher spectral efficiency than half-duplex systems. These demonstrations have motivated research in the area of full-duplex wireless communications and have made full-duplex a candidate technology for next generation wireless networks. The recent increasing amount of research on full-duplex systems has resulted in a variety of methods for self-interference mitigation and of protocol designs for networks with full-duplex nodes. In this tutorial, we will present the state-of-the-art of full-duplex technology and give some insight about potential applications in future communications systems, in particular in the context of fifth-generation (5G) cellular networks and 802.11ax WLAN. The attendees will learn about the challenges that need to be overcome at the RF level, physical layer level, and network level, and about the trade-offs between performance gains and hardware complexity associated with full-duplex. The tutorial is targeted to a broad audience with the aim that attendees with different backgrounds can understand the overall challenges of full-duplex system design as well as potential benefits. There are still improvements to be made to current proposed full-duplex solutions before they can be integrated into commercial networks. The teaching aim of the tutorial is to familiarize the attendees with the main to-date results on full-duplex nodes and networks and highlight some of the aspects that need to be addressed by future research.
