Table 3
Accuracy of different channel combinations (the channel in the channel combination is meant to expand the dataset by extracting instantaneous frequency features from the channel using HHT. If there is more than one channel, it means that their instantaneous frequency feature are extracted channel by channel and added to the original signal dataset).
