On Numerosity of Deep Neural Networks

Neural Information Processing Systems

Recently, a provocative claim was published that number sense spontaneously emerges in a deep neural network trained merely for visual object recognition.



Semi-supervised Learning with Ladder Networks

Neural Information Processing Systems

We combine supervised learning with unsupervised learning in deep neural networks. The proposed model is trained to simultaneously minimize the sum of supervised and unsupervised cost functions by backpropagation, avoiding the need for layer-wise pre-training. Our work builds on top of the Ladder network proposed by V alpola [1] which we extend by combining the model with supervision. We show that the resulting model reaches state-of-the-art performance in semi-supervised MNIST and CIFAR-10 classification in addition to permutation-invariant MNIST classification with all labels.
