(above). Correction: In Oct. 2000, a typo was discovered on page 209 (page 23 of the manuscript), 9th line from the bottom of the page. "d >= 10" printed in the published version should be "d/cos( beta/4) >= 10" instead. This is an error in a model parameter, and this error should lead to quantitative (but not much qualitative) changes in model performance compared to those presented in this paper. Also, Delta (theta) in the expression for W means |Delta (theta)|. The same typo was also in the published version of Li Z. 1998 Neural Computation, but is corrected in the version below posted on this webpage (below). Hence, for all correct parameters of the model, download this paper.
