... calculated average current, whereas the measured dither amplitude is always more than the calculated dither amplitude. These differences in the dither amplitude are caused by factors such as noise in the current measurement and the effect of temperature on coil resistance and inductance. In particular, the noise in the current signal makes it difficult to determine ...

... using the decision tree represents a single IF-THEN rule. Unfortunately, the algorithm. Secondly we complete this group up to reducts by decision tree-based algorithms do not perceive noise and using discernibility function techniques. Finally, we select only contradictions in data because they assume that Bayes error one reduct with the best classification accuracy by using ...
