<FONT face=Verdana>A computeraided tuning method based on machine learning is proposed in the paper.In the method
an effect model that reveals the relationships between the tunable screws and filter electrical performance is firstly developed by using a kernel algorithm
according to the data sets from tuning experience of technician.Then
a tuning procedure of filters is constructed by using the developed machine learning model.Finally
some experiments are carried out
and the experimental results confirm the effectiveness of the method.The approach is particularly suited to the computeraided tuning of volumeproducing filters.
