The left-most column consists of a random sample of hand-written digits from the test set. The other columns are analogies generated from the learned model p(x|z,y). The writing style ('z') of each generated row is inferred from the test-set image in the left-most column, while the class label ('y') iterates from [0,...,9] from left to right. We think this success is quite exciting, and that it accentuates a big advantage of the fully probabilistic approach: the ability to perform meaningful inferences on which the model was not explicitly trained.
Articulated Pose Estimation by a Graphical Model with Image Dependent Pairwise Relations
We present a method for estimating articulated human pose from a single static image based on a graphical model with novel pairwise relations that make adaptive use of local image measurements. More precisely, we specify a graphical model for human pose which exploits the fact the local image measurements can be used both to detect parts (or joints) and also to predict the spatial relationships between them (Image Dependent Pairwise Relations). These spatial relationships are represented by a mixture model. We use Deep Convolutional Neural Networks (DCNNs) to learn conditional probabilities for the presence of parts and their spatial relationships within image patches. Hence our model combines the representational flexibility of graphical models with the efficiency and statistical power of DCNNs. Our method significantly outperforms the state of the art methods on the LSP and FLIC datasets and also performs very well on the Buffy dataset without any training.
