Biomorphic Robot Controls: Event Driven Model Free Deep SNNs for Complex Visuomotor Tasks

The long term goal of this research within the framework of the European Human Brain Project (HBP) is to understand, to model and to translate biomorphic neural principles towards biocybernetic robot control systems. In comparison to conventional computing the brain is superior in terms of energy efficiency, robustness and adaptivity. Thus, we investigate into modeling biologic processes enabling the brain to perform sensomotoric computation and finally to implement it in silicon in form of biomorphic hardware. Todays neuromorphic hardware consists of spiking neural networks (SNNs) which can perform fast and efficient computations with continuous input - output streams based on synaptic plasticity. We focus on brain like senso-motor control tasks and ground them with the help of real robots. Spiking neural networks have the potential on replicating real neurons representing parts of their biological characteristics. SNNs are capable to perform synaptic spike-based communication with local brain functionalities supporting learning with the help of neural plasticity mechanisms. We assume, that the brain is forming sensor-motor primitives within building blocks composed for object detection, localization, event prediction, and finally the generation and execution of motion and interaction. The combination of neural motion primitives represent complex muscle motor synergies with the potential to learn complex large scale motions. Our SNN control architecture is capable to perform tasks like object recognition, object tracking, target reaching and grasping as well as collision- and obstacle avoidance. Closing the visuomotor loop by mapping the learned visual representation to motor commands show that SNNs learn without any planning algorithms nor inverse kinematics. SNNs are event driven and model free. We introduce deep continuous local learning mechanisms achieving state of the art robot accuracy on event stream benchmarks. Biologically plausible reward-learning rules based on synaptic sampling show that SNNs are capable of learning policies and various movement characteristics.

Links between reward-modulated synaptic plasticity and online reinforcement learning show proposing results. The hyper-parameters of this neuromodulation and their impact on performance are to be discussed with the help of some closed-loop sensorimotor experiments. The potential of deep reinforcement learning for target reaching affects object interaction, manipulation and grasping tasks and allows its realtime execution within dynamic situations. An event-driven binocular DVS system is used in stereo mode driven by micro saccades. The spiking feedback information from the DVS and from proprioception is mapped towards motion generating SNNs applying reward coupling and prediction error minimization techniques.

Future work towards the effective use of neuromorphic vision with emphasis to eye movement, micro saccades, visual affordance learning and high performance event prediction will be discussed. In addition it can be shown, that the brain-inspired computational paradigm can be extended towards SNN based navigation and mapping (BSLAM) forming episodic spatial neural memories with multi-scale learning capabilities. A software framework for developing and programming the related SNN-clusters and some complex biomorphic robot platforms are outlined.

Exploring online social ecosystems through bio-inspired perspectives

Understanding how organisms reproduce and adapt to their environment and evolve is a significant issue in natural ecosystems. Similarly, online social systems such as social media are new ecosystems with complex functions. Recently, there has been a lot of attention on how much we can explain the ecosystem of social systems by using analogies of biological ecosystems because of the expectation that natural ecosystems provide a comprehensive theory for understanding social systems. In line with this research approach, I will discuss how the phenomena occurring in the online social ecosystem relate to living organisms' characteristics in this talk. By doing so, we hope to develop a strategy to transform online social systems into a constructive and democratic forum for making suggestions, debating, and communicating new ideas.

Balancing Control in Systems

Maintaining balance in the nature is the most factor for human beings to keep our lives in peace and happiness. If the balance in nature breaks, human beings will be in danger and disaster. A human body itself is a balanced system. Likewise, balancing the system plays an important role in every dynamical machine and system. The balancing systems can be categorized into two parts: passive and active. The passive balance can be achieved from mechanical design such as center of gravity-based design and parallelogram. The active balance can be challengingly achieved by using various control algorithms. Each system requires an appropriate control algorithm to satisfy the balance from unstable condition. Therefore, the selection of appropriate balancing control algorithm is quite important in the system, which leads to the development of balancing control algorithms. In this talk, research from the inspiration of the balancing mechanism and control is introduced and shared. The balancing control of various systems is introduced in association with the appropriate control algorithms used in artificial intelligence, control and robotics areas.
