The network used 40 non-radially symmetric Gaussian basis functions (width parameter = 1.25), the centers of which were positioned by using the Kohonen LVQ algorithm.
Criterion 1, rejection if sum of HLN outputs is <θ, for θ = 0.7; criterion 2, rejection if maximum HLN output is <θ, for θ = 0.4. For comparison, rejection thresholds were selected that gave comparable overall proportions of correctly recognized patterns for the known species.
