The Training log gives you an overview and details of all the trainings a classifier has completed. You can access the Training log by clicking on in the top right of the training data view in the window.
This will take you to the following overview. Under «Version» you can see how many times the classifier has already been trained. In addition, you can see at what time the training was started, which training method was selected and how many training examples the data set contained. Under «Status» you can see whether the training was completed or not. «Accuracy» provides information about the number of examples that could be correctly classified with the available data.
