make attention

Dependencies:

• server

This page is a high level overview of the library; to dig into the details read the comprehensive overview.

Library provides an Module: AttentionModule.

Agents:

• ForgettingAgent: carries out the forgetting process based on LTI of Atoms.
• HebbianUpdatingAgent updates HebbianLinks; it deals with atoms that are likely to be important at the same time.
• ImportanceDiffusionAgent spreads short term importance along HebbianLinks using a diffusion approach
• ImportanceSpreadingAgent Spreads short term importance along HebbianLinks
• ImportantUpdatingAgent updates the AttentionValues of atoms (see wiki page; this Agent carries out:
  • stimulus to STI and LTI conversion
  • rent collection
  • rent adjustment and taxing when AtomSpace funds go out of homeostatic bounds.
• STIDecayingAgent implements a simple forgetting mechanism that doesn't rely on the complexities of the full Economic attention allocation system
