About this Research Topic
The recent wave of impressive advancements in deep learning cannot hide that their scope is still limited. Neural networks are impressive in classifying objects or to handle a limited set of well-defined control tasks. Deep neural network approaches shine in learning complex patterns in input signals via hierarchical feature extraction, but they are extremely hungry in resources such as labelled data or computational power that are often very scarce in robotic application domains. The challenges when deploying these networks from simulation to the real world are indicative of the problems of scaling up neural network-based AI to realistic, dynamic and unpredictable environments.
An alternative strand of research in robotic AI is focused on symbolic principles, where the world is casted in logical predicates, rules and conditional relationships to plan actions or to reason on context and experience. This knowledge and the associated rules must be hand-coded by experts, which makes symbolic AI better interpretable and predictable than “black-box” deep neural network components, which can be very necessary properties for robotic applications, e.g. in order to avoid physical damage to nearby humans. Drawbacks of symbolic AI are how to ground sensor input to symbols and the complexity of providing formal descriptions of complex, realistic environments.
With this Research Topic, we call for papers that will help in understanding the added value of combining principles from symbolic AI with the most recent advances in deep neural networks. We seek to understand where is the added value, and how synergies should be achieved between both branches in artificial intelligence.

• Deep symbolic reinforcement learning
• Symbol grounding of raw robotic sensor input
