Center node: "Statistical Biases in Backpropagation Learning  Keywords: Cognitive Science, Pattern recognition"
  Abstract: The paper investigates the statistical effects which may need to be exploited in supervised learning. It notes that these effects can be classified according to their conditionality and their order and proposes that learning algorithms will typically have some form of bias towards particular classes of effect. It presents the results of an empirical study of the statistical bias of backpropagation. The study involved applying the algorithm to a wide range of learning problems using a variety of different internal architectures. The results of the study revealed that backpropagation has a very specific bias in the general direction of statistical rather than relational effects. The paper shows how the existence of this bias effectively constitutes a weakness in the algorithm's ability to discount noise.
