Global Mean-Amplitude Enhanced SNN Coherent Ising Machine

Physics-driven amplitude stabilization for spiking neural network-based coherent Ising machines. Based on Jiang et al. (arXiv: 2509.13917).

Core Methodology

• Global mean-amplitude feedback enhances spiking neural network CIM
• Physics-driven amplitude stabilization prevents oscillation divergence
• 27% improvement in Max-Cut solution success rates vs conventional SNN-CIM
• Validated on traffic assignment problems (generalizes beyond Max-Cut)

Architecture

1. SNN encodes Ising model spins as neuron states
2. Global mean-amplitude feedback stabilizes collective dynamics
3. Physics-driven amplitude correction enforces energy landscape convergence
4. Readout maps final spiking states to optimization solution

When to Use

• Combinatorial optimization (Max-Cut, graph partitioning, traffic assignment)
• Coherent Ising Machine implementations
• Spiking neural network optimizers
• Physics-inspired neural computation
• Problems requiring amplitude stabilization in oscillatory networks

Key Advantages

1. 27% success rate improvement over baseline SNN-CIM
2. Generalizes beyond Max-Cut to real-world optimization
3. Physics-driven (not learned) stabilization — no training required
4. Compatible with existing SNN hardware implementations
