Construction of an Intelligent Machine
Following the Brain Based Model
Design should be constrained by these principles: Active sensing and autonomous movement in the
environment. Organize the signals from the environment into
categories without a priori knowledge or instruction. Incorporate a simulated brain with detailed neural
dynamics and neuroanatomy. Engage in a behavioral task and adaptation of behavior
when an important environmental event occurs. Allow comparisons with experimental data acquired
from animal systems.
