What is technically defined as external input? If this can simply be
fulfilled by using perceptual data to gain facts and data about the
environment, then this data can serve as fuel for improvement, and data is
cheap. Or does external input have to satisfy its own complexity
requirements? (excuse my ignorance if this is basic academic knowledge,
maybe somebody could point me to specific literature if needed).
