Then again, autoencoders are not a true unsupervised learning technique (which would imply a different learning process altogether), they are a self-supervised technique, a specific instance of supervised learning where the targets are generated from the input data. Before wrapping up, I want to bring up 2 limitations of the YOLO algorithm. They are stored at ~/. Using tfhub it is simple to retrain the top layer of the model to recognize the classes in our dataset.
