# Catalyst GSC SNN Benchmark

Spiking Neural Network for keyword spotting on Google Speech Commands using spike-to-spike delta modulation encoding.

## Model Description

- **Architecture**: 40 → 512 (recurrent adLIF, spike-to-spike) → 12
- **Neuron model**: Adaptive Leaky Integrate-and-Fire (adLIF) with spike-to-spike delta encoding
- **Training**: Surrogate gradient BPTT, fast-sigmoid surrogate (scale=25)
- **Hardware target**: Catalyst N1/N2/N3 neuromorphic processors
- **Quantization**: Float32 weights -> int16, membrane decay -> 12-bit fixed-point

## Results

| Metric | Value |
|--------|-------|
| Float accuracy | 88.0% |
| Quantized accuracy (int16) | 87.5% |
| Parameters | 290,828 |
| Quantization loss | 0.5% |

## Reproduce

```bash
git clone https://github.com/catalyst-neuromorphic/catalyst-benchmarks.git
cd catalyst-benchmarks
pip install -e .
python gsc/train.py --device cuda:0
```

## Deploy to Catalyst Hardware

```python
import catalyst_cloud

client = catalyst_cloud.Client()
result = client.simulate(
    model="catalyst-neuromorphic/gsc-snn-benchmark",
    input_data=your_spikes,
    processor="n2"
)
```
