Delay Line Reservoir Computer Structure

Delay Line Reservoir Computing (DLRC) is a recently introduced paradigm in the fields of machine learning and artificial neural networks (ANN). The Applied Physics Research Group (APHY) of the VUB developed a novel cascaded DLRC structure, aimed at real-time signal processing.

Our cascaded DLRC structure offers short-cycle supervised learning of complex nonlinear transformations from example and generalization to previously unseen inputs. 

Possible applications:

  • Nonlinear real-time audio processing
  • Timeseries forecasting
  • Noise suppression
  • Dropout compensation
  • General nonlinear filtering

Innovation Strengths / Competitive Advantages

  • Implementable as (embedded) DSP software or as IP block in an FPGA
  • Scalable and customizable
  • Simplified and fast training as compared to other ANN
  • Learning and execution platforms can be different
  • On-the-fly target function reconfiguration is possible

Market Opportunities / Industrial Target Group 

Our DLRC solution can be applied in any situation where sensor signals or input data needs to be discriminated, classified, or transformed via an a priori unknown or difficult to describe function or set of rules, defined by a (possibly limited) set of input-output examples.
Our target audience consists of the key players in the automotive, medical and industrial high-tech industries, challenged by complex, possibly real-time, signal processing requirements.
