You have a modified version of this example. % create a dummy dataset with the same size of the combined datastores (if ds1 has 100 images and ds2 has 100 images then dummy has 200 images. Deep learning is a type of supervised machine learning in which a model learns to perform classification tasks directly from images, text, or sound. Fermer. Deep learning is usually implemented using a neural network. Desktop. However, with wireless signals it is common for the classes in the training set to be imbalanced. The approach used in this example for speaker identification is shown in the diagram. The training images are of size 656x875x3 but the input layer expects images of size 64x64x1. It didn't show any problem with that type of images when I applied countEachLabel function. Create a blocked image from a sample label image. Add the label A to the first half of the files, and the label B to the second half. countEachLabel opens a new pool based on the default parallel bigimageDatastore object is not recommended. weight: Median frequency balancing weights each class using the median frequency. formats.
