🚀 Quick Start

# Your first spiking neural network with LAVA
import lava.lib.dl.slayer as slayer
import torch
 
class SimpleSpikingNet(torch.nn.Module):
    def __init__(self):
        super().__init__()
        # Spiking neuron parameters
        neuron_params = {
            'threshold': 1.0,
            'current_decay': 0.9,
            'voltage_decay': 0.8,
        }
        
        # Build network
        self.blocks = torch.nn.ModuleList([
            slayer.block.cuba.Dense(
                neuron_params, 784, 128, weight_norm=True
            ),
            slayer.block.cuba.Dense(
                neuron_params, 128, 10, weight_norm=True
            ),
        ])
    
    def forward(self, spike_input):
        # Process through spiking layers
        for block in self.blocks:
            spike_input = block(spike_input)
        return spike_input
 
# Deploy to neuromorphic hardware
net = SimpleSpikingNet()
# Loihi backend for Intel neuromorphic chip
from lava.lib.dl.netx import hdf5
hdf5.Network(net.export_hdf5('model.net')).run()

📊 Neuromorphic vs Traditional AI (2025)

🧠 Why Neuromorphic Computing?

Event-Driven Efficiency

# Traditional AI: Process every frame
traditional_power = frames_per_second * operations_per_frame * energy_per_op
# Result: Constant high power consumption
 
# Neuromorphic: Process only changes
neuromorphic_power = events_per_second * spikes_per_event * energy_per_spike
# Result: Power proportional to activity (often 100x less)
