CIRCUIT COMPONENTS

noise

A circuit component that generates pseudo-random sparse sets.

Details and properties

The noise component has no input and returns one output block.
The dimension and population of the generated representations is governed by the outbound slot’s hyperparameters.

Property	Default	Description
`send`	required	a single output slot

Use standard style options to customize the component’s appearance in circuit schematics.

Additive noise

Add random noise to the input signal:

{ "hyperparameters": {"default": [1000, 10]},
  "dataflow": [
    {"component": "input", "send": [1]},
    {"component": "noise", "send": [2]},
    {"component": "output", "receive": [[1, 2]]}
  ]}

Subtractive noise

Use an inhibitory pathway to make the noise subtractive:

{ "hyperparameters": {"default": [1000, 10]},
  "dataflow": [
    {"component": "input", "send": [1]},
    {"component": "noise", "send": [2]},
    {"component": "output", "receive": [[1, {"slot": 2, "tags": ["inhibit"]}]]}
  ]}

def noise(config):
    n, p = config.get("send_blocks", [[0, 0]])[0]

    def f(*blocks):
        return (
            sorted(
                rng.choice(range(1, n + 1),
                    size=p,
                    replace=False).tolist()),
        )

    return {
        "function": f,
        "checks": ["input", "oneout"],
        "label": "~", "fill": 13, "size": 18
    }
