Fixed an issue that any training dataset information is not updated when we change the training set combo box.
In addition, because the number of iterations may be meaningful when the users only use "Instance" section not "Heatmap" section, the users who use both "instance and Heatmap" section may be confused about the number of iterations. Thus, the iteration information is removed on the main page. Instead, the users can confirm the iteration information on the instance section whenever they reload their classifier.
