This document discusses using a convolutional neural network (CNN) for perceptual change recognition. It describes using a pre-trained VGG16 CNN model and fine-tuning the fully connected layers. The CNN is able to learn border-ownership representations from unlabeled data and can recognize changes between ambiguous figures with over 80% accuracy. Training takes around 158 simulation steps, with recognition performance improving over time.
