# threshold-majority7

7-input majority gate. Outputs 1 when at least 4 of 7 inputs are high.

## Function

majority7(a, b, c, d, e, f, g) = 1 if sum >= 4, else 0

## Architecture

Single neuron: weights [1, 1, 1, 1, 1, 1, 1], bias -4

Fires when: sum >= 4

## Parameters

| | |
|---|---|
| Inputs | 7 |
| Outputs | 1 |
| Neurons | 1 |
| Layers | 1 |
| Parameters | 8 |
| Magnitude | 11 |

## Usage

```python
from safetensors.torch import load_file
import torch

w = load_file('model.safetensors')

def majority7(a, b, c, d, e, f, g):
    inp = torch.tensor([float(a), float(b), float(c), float(d), float(e), float(f), float(g)])
    return int((inp @ w['neuron.weight'].T + w['neuron.bias'] >= 0).item())

print(majority7(0, 0, 0, 1, 1, 1, 1))  # 1
print(majority7(0, 0, 0, 0, 1, 1, 1))  # 0
```
