Fewer Histogram Features

Posted: August 18, 2019 at 9:12 am

After the lack of success in the previous experiment using the 768 element vector, I have the results of the 96 histogram bin experiment. During the search, Talos reported a peak validation accuracy of 73.3%. The best model reported a validation accuracy of 66.4% and a training accuracy of 99.7%. Clearly the model is learning the training set well, but again not generalizing to the validation set. The following image shows the confusion matrix for the validation set. I note that there is no appreciable difference between 1000 and 10,000 epochs to validation accuracy.
