Analysis and Fully Memristor-based Reservoir Computing for Temporal Data Classification
🤖 AI Summary
To address the high power consumption and latency of digital implementations in time-series classification, this work proposes a fully memristor-based hardware reservoir computing architecture. We present the first end-to-end memristive reservoir implementation, integrating analog-domain dynamical modeling, spike-timing-dependent plasticity (STDP)-driven weight mapping, and hardware-efficient spike-state encoding. Furthermore, we introduce a novel memristive weight dynamic calibration mechanism enabling online, brain-inspired temporal learning. Evaluated on benchmark tasks—including NARMA10 and chaotic time-series classification—the system achieves over 92% accuracy while reducing energy consumption by three orders of magnitude compared to GPU-based implementations. This work establishes a scalable, fully analog hardware paradigm for low-power, high-throughput neuromorphic time-series processing.
