Coalitional Multimedia Signal Processing in Smart Device Networks
Digital signal processing (DSP) is a key enabler of the development of future communication networks and in particular of the Internet of Things (IoT). On the other hand, the communication between electronic devices made available in the IoT may become an enabler for significant performance improvement in the DSP functionalities of individual devices. By cooperating with other devices, each individual device may seek to improve its own DSP performance, beyond 'stand-alone’ performance, even when other devices perform different DSP tasks. Managing cooperation in a 'coalition' of devices with different DSP tasks first requires a solid understanding of the opportunities for cooperation as well as of the achievable performance gains. Secondly, centralized and distributed 'coalitional' signal processing algorithms have to be developed, including signal fusion, topology selection and resource allocation procedures. General ideas and algorithms will be discussed as well as illustrated by means of applications in the speech & audio signal processing context.

Synthetic Molecular Communication: Fundamentals, Opportunities, and Challenges
Synthetic molecular communication is an emerging research area offering many interesting and challenging new research problems for engineers, biologists, chemists, and physicists. Synthetic molecular communication is widely considered to be an attractive option for communication between nano-devices such as (possibly artificial) cells and nano-sensors. Possible applications of nano-communication networks include targeted drug delivery, health monitoring, environmental monitoring, and "bottom-up" manufacturing. The IEEE and ACM have recently founded several new conferences and journals dedicated to this exciting new and fast growing research area..
In this keynote, we will give first a general overview of the areas of synthetic molecular communication and nano-networking. Components of synthetic molecular communication networks, possible applications, and the evolution of the field will be reviewed. We will focus particularly on diffusion based synthetic molecular communication, identify the relevant basic laws of physics and discuss their implications for communication system design. Subsequently, several communication engineering design and signal processing problems will be discussed, including detection, channel estimation, parameter estimation, and synchronization. Furthermore, some experimental results will be provided. In the last part of the talk, we will discuss some research challenges in synthetic molecular communication.

Deep Convolutional Networks: An Opportunity for Signal Processing
Deep convolutional network have obtained spectacular results in machine learning to solve complex classification and regression tasks. They are now also used to synthesize images and audio signals with Generative Adversarial Networks and recurrent networks, to suppress noise and solve inverse problems. They are thus also invading the signal processing arena.
Deep convolutional networks are based on filter banks or recursive filters, which are no stranger to signal processing, but they involve complex cascade of non-linearities, with optimization algorithms which are not understood. It brings new air and problems to signal processing and information theory, which is an opportunity for signal processing research. I will explain how deep neural networks relate to classic signal processing tools including wavelets, compression and sparse inverse problems, and discuss challenging open problems for image and audio processing.

Sensing and Processing with Events
Conventional machine vision and audition faces a fundamental latency-power tradeoff, where decreasing latency means increasing sensor sample rate and therefore power consumption. The communication by spikes in the brain provides the inspiration for our developments of event-based vision and audio sensors and processing, which avoids this latency-power tradeoff. This talk will provide a personal perspective on developments of event-based vision and audio sensors, algorithms, and applications. It will include a demonstration of a recent vision sensor. There are many opportunities for novel signal processing and machine learning approaches using these asynchronous sensors.
