                               Abstract

An ideal visual system is calibrated if its estimates reflect the
actual state of the scene: Straight lines, for example, should be judged 
to be straight. If an ideal visual system is modeled as a neural network,
then it is calibrated only if the weights linking elements of the
the network are assigned correct values. I describe a method 
(`Learning by Assertion') for calibrating an ideal visual system by 
adjusting the weights. The method requires no explicit feedback or prior 
knowledge concerning the contents of the environment. This work is
relevant to biological visual development and calibration, to the 
calibration of machine vision systems, and to the design of adaptive
network algorithms.
