Abstract: A new area of machine learning research called deep learning has moved machine learning closer to one of its original goals: artificial intelligence and feature learning. Originally the key idea of training deep networks was to pretrain models in completely unsupervised way and then fine-tune the parameters for the task at hand using supervised learning. In this study, deep learning is applied to a facial keypoints detection. The task is to predict the positions of 15 keypoints on grayscale face images. Each predicted keypoint is specified by a real valued pair in the space of pixel coordinates. In the experiments, we pretrained a Deep Belief Network (DBN) and finally performed discriminative fine-tuning. We varied the depth and size of the network. We tested both deterministic and sampled hidden activations, and the effect of additional unlabeled data on pretraining. The experimental results show that our model provides better results than the publicly available benchmarks fo r the dataset. (More)
