Simon DavidsonSpiNNaker-2
Abstract. SpiNNaker was designed to be a flexible, low-power neuromorphic computing platform allowing both computation neuroscientists and roboticists to design large-scale neural networks running in real time. Since the first SpiNNaker chips became available in 2011, we have built up a user base of more than one hundred institutions around the world. Now, as part of the Human Brain Project (HBP) we - together with partners in TU Dresden - have been working on the second generation SpiNNaker architecture. In my talk I'll present this new architecture and discuss how we got there, including the lessons we learned from the first SpiNNaker machine and our plans for SpiNNaker going forward.

Jennifer HaslerPhysical Computing towards building Large-Scale Brain Computations
Abstract. Cognitive Neuromorphic systems are gaining increasing importance in an era where CMOS digital computing techniques are meeting hard physical limits. These silicon systems mimic extremely energy efficient neural computing structures, potentially both for solving engineering applications as well as understanding neural computation.
Neuromorphic techniques are of increasing interest along with other Physical computing directions, such as Analog, Quantum, and Optical computation. Understanding and developing computational theory of physical computation became relevant with the advent of large-scale Field Programmable Analog Arrays (FPAA) as well as other recent physical computing implementations. Digital computation is enabled by a framework developed over the last 80 years. Analog computing techniques result in 1000x improvement in power or energy efficiency, and a 100x improvement in area efficiency, compared to digital computation. FPAA structures have demonstrated applications examples range from acoustics and sensor processing, classification, embedded machine learning, image processing, communications, RF signal processing, and optimal path planning using coupled PDEs.
Towards this end, we provide a glimpse at what the technology evolution roadmap looks like for these systems so that Neuromorphic engineers may gain the same benefit of anticipation and foresight that IC designers gained from Moore's law many years ago. Scaling of energy efficiency, performance, and size will be discussed as well as how the implementation and application space of Neuromorphic systems are expected to evolve over time. We will focus on a number of techniques for long-term modulation processes applicable to learning mechanisms as well as other slow modulatory processes.

Alan WinfieldExperiments in Artificial Theory of Mind
Abstract. Theory of mind is the term given by philosophers and psychologists for the ability to form a predictive model of self and others. In this talk I will advance the hypothesis that simulation-based internal models offer a powerful and realisable, theory-driven basis for artificial theory of mind. Proposed as a computational model of the simulation theory of mind, our simulation-based internal model equips a robot with an internal model of itself and its environment, including other dynamic actors, which can test (i.e. simulate) the robot's next possible actions and hence anticipate the likely consequences of those actions both for itself and others. I will present a series of experiments which each demonstrate some aspect of artificial theory of mind.

Karlheinz MeierHow to compute with physical laws
Abstract. The success of modern computing is entirely based on the idea of describing parameters by abstract symbols and function by algorithms acting on the parameters. The Turing machine is a corresponding complete mathematical theory of computation. Several specific architectures like the von Neumann architecture and its many variations have been devised to implement this approach with outstanding successes.

Many current challenges of computing address the simulation of complex systems, in which a very large number of elements interact with each other. Typically, the number of elements is much larger than the number of processors and the issue of scaling is of crucial importance. Scalability issues are of particular importance when the computational goal is to describe the dynamics of the complex system at different time scales.

The brain is a particular example of a complex system with timescales covering milliseconds to years corresponding to more than 10 orders of magnitude. The mechanisms of learning and plasticity at those scales are of extreme importance for advancing brain science but equally important for the development of a more biologically grounded AI with a more generic application space.

Physical model neuromorphic systems using analog or mixed-signal circuits emulating neuronal dynamics have been proposed and built to overcome the scaling and simulation time problem in particular for the implementation of learning processes. In my talk I will introduce the idea of physical computing, show actual implementations and applications with special emphasis the exploitation of stochastic processes and very recent ideas for biological approaches to deep learning.

Eleni VasilakiSynaptic plasticity and learning in spiking neural networks.
Abstract. Neuroscience has long been an inspiration for Artificial Intelligence and Machine Learning. In this talk I will present some fundamental ideas about biological learning, and how these are related to Machine Learning. More particularly I will discuss how simple concepts from the 1940's underline ideas about memory formation in both artificial and natural systems. I will then proceed to recent experimental and theoretical results and discuss what do they tell us about the way information is encoded in different brain areas. I will also show how these results not only inspire Artificial Intelligence but also future electronics, and present concrete examples where novel electronic circuits demonstrate functionality akin to biological circuits.
