Exponentially Weighted Imitation Learning for Batched Historical Data

Qing Wang, Jiechao Xiong, Lei Han, peng sun, Han Liu, Tong Zhang

Neural Information Processing Systems

We consider deep policy learning with only batched historical trajectories. The main challenge of this problem is that the learner no longer has a simulator or "environment oracle" as in most reinforcement learning settings.


GT-GAN: GeneralPurposeTimeSeriesSynthesis withGenerativeAdversarialNetworks

Neural Information Processing Systems

However, there are no existing generative models that showgood performance for both types without anymodel changes. Therefore, we present a general purpose model capable of synthesizing regular and irregular time series data.





Learning Conditioned Graph Structures for Interpretable Visual Question Answering

Will Norcliffe-Brown, Stathis Vafeias, Sarah Parisot

Neural Information Processing Systems

Understanding both the question and image, as well as modelling their interactions requires us to combine Computer Vision and NLP techniques. The problem is generally framed in terms of classification, such that the network learns to produce answers from a finite set of classes which facilitates training and evaluation.
