Google's EfficientNet, on-device training from Apple, research ethics, drawing faces from voices, and more...
This week in deep learning we bring you a new efficient, accurate network architecture from Google, an acquisition by Twitter to help fight fake news, an update to on-device ML from Apple, and a disturbing research trend that brings the ethics of AI into sharp focus.
You may also enjoy an overview of graph neural networks in PyTorch, implementing backpropagation in NumPy, a neural network-based drone autopilot running on a microcontroller, depthwise 3D convolutions in Keras, and extremely data efficient network training from DeepMind.
As always, happy reading and hacking. If you have something you think should be in next week's issue, find us on Twitter: @dl_weekly.

Abstract: Large scale deep learning excels when labeled images are abundant, yet data-efficient learning remains a longstanding challenge....Our work tackles this challenge with Contrastive Predictive Coding, an unsupervised objective which extracts stable structure from still images. The result is a representation which, equipped with a simple linear classifier, separates ImageNet categories better than all competing methods, and surpasses the performance of a fully-supervised AlexNet model. When given a small number of labeled images (as few as 13 per class), this representation retains a strong classification performance, outperforming state-of-the-art semi-supervised methods by 10% Top-5 accuracy and supervised methods by 20%....
Abstract: With a view to bridging the gap between deep learning and symbolic AI, we present a novel end-to-end neural network architecture that learns to form propositional representations with an explicitly relational structure from raw pixel data. In order to evaluate and analyse the architecture, we introduce a family of simple visual relational reasoning tasks of varying complexity. We show that the proposed architecture, when pre-trained on a curriculum of such tasks, learns to generate reusable representations that better facilitate subsequent learning on previously unseen tasks when compared to a number of baseline architectures. The workings of a successfully trained model are visualised to shed some light on how the architecture functions.
