Spatio-Temporal Representation on Neuromorphic Architecture

The latest achievements in artificial intelligence and neural networks, especially deep neural architecture in large-scale neuromorphic hardware implementation such as SpiNNaker , and in cognitive robotics and neurorobotics, with the widespread use of robots such as iCub and the latest Pepper platform, provide the opportunity to significantly advance our understand human cognition and brains and to reach human-level artificial intelligence. One of the key success factors in deep learning is its hierarchical structure inspired by biological processes in the primate visual cortex, as with convolutional deep networks able to learn rich representations. They are grounded in optimization methods with high precision for training may consume large training datasets and computational resources to learn complex tasks. That gives human level performance in static image recognition but raises adaptation issues. SpiNNaker is a neuromorphic computer architecture in massively parallel computing platform based on spiking neural networks (SNNs) in which neurons communicate by temporal code. Spike Timing Dependent Plasticity (STDP) is believed that it underlies learning and information storage in the brain. SpiNNaker is based on spiking, recurrent neural dynamics for very fast (even instantaneous) learning, online adaptability and extensibility, robustness against noise and computations with low numerical accuracy. However, it has preliminary results so far. The simple integration is not enough to meet requirements in developmental cognitive robotics and neurorobotics. We cannot rely only on the exponential increase in computing power to produce state of the art performance on a number of robotic tasks such as object/human behavior recognition and skill learning. The aim of STRoNA (Spatio-Temporal Representation on Neuromorphic Architecture) is to define the technology that will map a computational architecture onto neuromorphic computing circuits, hence to develop a cognitive model with spatio-temporal representation and learning algorithm for humanoid robots. The principal research objectives of the project are: (i) to investigate which spatio-temporal representations of spikes (or neural action potentials) can be used to achieve human level performance on visual perception; (ii) to develop a novel method to process spatio-temporal representation on a neuromorphic architecture to enable learning in online and interactive contexts; and (iii) to validate and adapt the developed system in real world robotics applications.
