Hebbian Links and Importance Spreading

This post will cover the HebbianLink, and two MindAgents, the ImportanceSpreadingAgent and the HebbianLearningAgent. The former agent spreads Short term importance (STI) along HebbianLinks, while the later updates the HebbianLink truth values.

Let’s look at the HebbianLink shall we?

There are …
