Quantization Error due to Signature Table Evaluations.
Abstract
The signature tables used in TAC ASSESSOR were assumed to be representations of some corresponding value functions evaluated at certain levels of the input features. The theoretical mean-squared-error due to this substitution was calculated for signature table 1 and table 5 in the FAC Target Importance Tables. The calculations were performed under two different assumption concerning the assumed value functions. Case 1 was that the signature table values resulted from evaluating the assumed value function at the given input feature values. Case 2 was that the function was evaluated at some feature values in the given quantization level indicated by the input feature. Next, an evaluation simulation was performed on three sets of 30 targets whose features were generated using uniform, exponential, and normal random variate generators scaled to the appropriate feature limits. Finally, the Spearman rank correlation coefficient was used to test the null hypothesis that there was no association between the evaluation methods.
