Monty.Attention.WeightPooler behaviour (ExTbpMonty.Core v0.1.0)

How several weights about one voxel become one — Monty's attention/weight_pooler.py.

A voxel can be told about by more than one sensor, or more than once by the same one, and something has to decide which of those opinions the attention system keeps.

Monty's WeightPooler is a one-method Protocol: anything callable with the values is a pooler. Here that is a function of arity one, ([number]) -> number, and pool/1 names the contract the way a behaviour would.

Summary

Callbacks

pool(list)

The contract a weight pooler satisfies: many weights in, one weight out.

Functions

negative_priority_max_pool(values)

Inhibition-dominating pooling: the maximum, unless anything is negative.

Callbacks

pool(list)

@callback pool([number()]) :: number()

The contract a weight pooler satisfies: many weights in, one weight out.

Functions

negative_priority_max_pool(values)

@spec negative_priority_max_pool([number()]) :: number()

Inhibition-dominating pooling: the maximum, unless anything is negative.

A negative weight means "do not look here", and a single such vote must not be outvoted by several positive ones, so the most negative value wins whenever there is one. Otherwise this is the plain maximum.
