** Aim and Scope **
Reservoir Computing (RC) defines a class of recurrent neural systems where the dynamical memory component is left untrained after initialization. Only a simple - typically linear - readout layer is adapted on a set of training examples, thereby allowing the use of simple learning strategies. The overall approach has intriguing features that attracted researchers during the last decade. First, it gives a refreshing perspective on the use of dynamical systems in machine learning for time-series data. Moreover, the resulting ease of implementation and fast training compared to fully trained architectures made it greatly appealing for experimental usage, mostly in academia. Yet, at the current stage of neural networks/deep learning research development, RC-based methods do present several downsides that prevent extensive (e.g., industrial) applications to problems of Artificial Intelligence size with human-level performance. One such fundamental downside is that in real-world applications, the training efficiency of RC risks to vanish completely, colliding with the complexity involved by possibly gigantic reservoir spaces, and cost-intensive hyper-parameter search, often required to get state-of-the-art results. The difficulty in effectively dealing with huge input-output spaces is a related known RC issue that complicates matters further. Overcoming complexities of this kind represents a major challenge in RC research nowadays. On a different side, methodological, architectural and theoretical studies on RC have the potentiality to both develop a deeper understanding of the operation of (fading memory) dynamical neural systems, and to foster the progress of their training algorithms. Besides, novel ways to control the organization of neural dynamics, such is the case of conceptors, can originate from RC and transfer to more general ML setups. A further research-attractive dimension of RC systems is that they are inherently amenable to be implemented in neuromorphic hardware. In this regard, photonic reservoirs are certainly among the most exciting possibilities emerged in the last few years, promising both ultra-fast processing and very low energy consumption. However, designing full optical RC networks for real-world applications currently needs to pursue primary goals, such as implementing non-linear reservoirs with optical readout training.

This session intends to give a new impetus to RC research within the international neural networks community. We then invite to submit papers on both theoretical and application sides of RC. In particular, this session calls for novel, potentially groundbreaking, contributions that specifically address open challenges in the RC field.

A list of relevant topics for this session includes, without being limited to, the following:

- Reservoir Computing for Artificial Intelligence problems (e.g., vision, natural language processing, etc.)
- Reservoir Computing methods for fully trained Recurrent Neural Networks (including hybrid approaches)
- Neuromorphic Reservoir Computing
- Novel Reservoir Computing architectures, models and training algorithms
- Theory of dynamical systems in neural networks, including stability of input-driven temporal embeddings
- Statistical Learning Theory of Reservoir Computing networks
- Ensemble learning and Reservoir Computing
- Advancements in Reservoir Computing models, e.g. Echo State Networks and Liquid State Machines
- Conceptors
- Deep Reservoir Computing
- Reservoir dimensionality reduction, efficient reservoir hyper-parameter search and learning
- New applications of Reservoir Computing
