Reservoir Computing Using DNA Oscillators.

Area of Science:

• Biomolecular Engineering
• Computational Neuroscience

Background:

• Reservoir computing (RC) leverages a fixed reservoir to project inputs into a high-dimensional space.
• Coupled deoxyribozyme oscillators have been previously explored as RC reservoirs.
• Molecular computation offers a novel paradigm for information processing.

Purpose of the Study:

• To develop a DNA-based readout layer for molecular analog multiplication.
• To introduce a new encoding method for reduced reaction times in DNA-based RC.

Main Methods:

• Utilizing an n-phase molecular oscillator (n ≥ 3) as the reservoir component.
• Implementing the readout layer via molecular reactions, specifically DNA strand displacement (DSD).
• Developing and applying a novel encoding strategy to accelerate molecular reactions.

Main Results:
