We notice however that much of research on neural machine translation has focused on European languages despite its language agnostic nature. ... Never trying to connect to any publications (i.e. We show that the gap can be upper bounded by some form of dispersion measure of the likelihood ratio, which suggests the bias of variational inference can be reduced by making the distribution of the likelihood ratio more concentrated... Unsupervised domain transfer is the task of transferring or translating samples from a source distribution to a different target distribution. In order to test this method, we introduce a new environment featuring varying difficulty levels, along with moving goals and obstacles. While a lot of progress has been made in recent years, the dynamics of learning in deep nonlinear neural networks remain to this day largely misunderstood. 12/01/2020 ∙ by Yikang Shen, et al. We introduce the Professor Forcing algorithm, which uses adversarial domain adaptation to encourage the dynamics of the recurrent network to be the... Neural machine translation has become a major alternative to widely used phrase-based statistical machine translation. This problem is under-explored, with most prior work relying on supervision from, e.g., 3D ground-truth, multiple images of a scene, image silhouettes or key-points. At each timestep, zoneout stochastically forces some hidden units to maintain their previous values. (2011), Bergstra, J., Courville, A., Bengio, Y. In this work, we study the case of binary classification and prove various properties of learning in such networks under strong assumptions such as linear separability of the data. While deep reinforcement learning excels at solving tasks where large amounts of data can be collected through virtually unlimited interaction with the environment, learning from limited interaction remains a key challenge. HoME integrates over 45,000 diverse 3D house layouts based on the SUNCG dataset, a scale which may facilitate learning, generalization, and transf...

Courville. Deep networks often perform well on the data distribution on which they are trained, yet give incorrect (and often very confident) answers when evaluated on points from off of the training distribution. While generative models have been explored on many types of data, little work has been done on synthesizing lidar scans, which play a key role in robot mapping and localization. PixelCNN models details very well, but lacks a latent code and is difficult to scale for capturing large structures.
