SpikySpace: Neuromorphic AI for Ultra-Efficient Time Series Forecasting

Today's deep dive: SpikySpace combines Spiking Neural Networks with State-Space Models to achieve 98% energy reduction for time series forecasting on neuromorphic hardware.

In this 21-minute episode of AI Daily, Jordan and Alex break down a breakthrough approach to energy-efficient AI inference. The SpikySpace paper shows how to co-design your model, software stack, and hardware target to enable sophisticated forecasting on coin-cell batteries and solar-powered edge devices.

What You'll Learn

• Why combining SNNs with State-Space Models (SSMs) is a natural fit for temporal sparsity
• How event-driven computation lets you skip 99% of calculations when data isn't changing
• The developer workflow for neuromorphic hardware: Lava, snnTorch, surrogate gradients, and SDK compilation
• Why simplified activation functions matter more than you think for edge deployment
• Practical applications: predictive maintenance, health monitoring, traffic sensing, industrial IoT

Key Technical Concepts

• Temporal sparsity: Compute follows the data, not the clock
• Surrogate gradients: Training non-differentiable spiking neurons with gradient descent
• Hardware-aware activation functions: Additions and bit-shifts instead of exponentials
• Spike encoding: Converting continuous signals to discrete events (rate vs latency encoding)
