threshold-minority5

5-input minority gate. Outputs 1 when at most 2 of 5 inputs are high. Complement of majority5.

Function

minority5(a, b, c, d, e) = 1 if sum <= 2, else 0

Architecture

Single neuron: weights [-1, -1, -1, -1, -1], bias 2

Fires when: sum <= 2

Parameters

Inputs	5
Outputs	1
Neurons	1
Layers	1
Parameters	6
Magnitude	7

Usage

from safetensors.torch import load_file
import torch

w = load_file('model.safetensors')

def minority5(a, b, c, d, e):
    inp = torch.tensor([float(a), float(b), float(c), float(d), float(e)])
    return int((inp @ w['neuron.weight'].T + w['neuron.bias'] >= 0).item())

print(minority5(0, 0, 0, 1, 1))  # 1
print(minority5(0, 0, 1, 1, 1))  # 0
