大型预先训练的语言模型可以在可以在一个可以“单通”中的任务上进行非常好，例如生成现实文本或合成计算机程序。但是，他们与需要无限的多步计算的任务斗争，例如添加整数或执行程序。令人惊讶的是，我们发现这些相同的模型能够执行复杂的多步计算 - 即使在少量射门中，当被要求执行操作“一步一步”时，表示中间计算的结果。特别是，我们通过询问它们将中间计算步骤发出到“ScratchPad”来执行变压器来执行多步计算。在一系列越来越复杂的任务范围内，从加入任意程序的执行范围，我们表明Scratchpads显着提高了语言模型执行多步计算的能力。

Semi-supervised learning (SSL) provides a powerful framework for leveraging unlabeled data when labels are limited or expensive to obtain. SSL algorithms based on deep neural networks have recently proven successful on standard benchmark tasks. However, we argue that these benchmarks fail to address many issues that SSL algorithms would face in real-world applications. After creating a unified reimplementation of various widely-used SSL techniques, we test them in a suite of experiments designed to address these issues. We find that the performance of simple baselines which do not use unlabeled data is often underreported, SSL methods differ in sensitivity to the amount of labeled and unlabeled data, and performance can degrade substantially when the unlabeled dataset contains out-ofdistribution examples. To help guide SSL research towards real-world applicability, we make our unified reimplemention and evaluation platform publicly available. 2 * Equal contribution 2 https://github.com/brain-research/realistic-ssl-evaluation 32nd Conference on Neural Information Processing Systems (NeurIPS 2018),

In this paper we introduce new methods for the improved training of generative adversarial networks (GANs) for image synthesis. We construct a variant of GANs employing label conditioning that results in 128 × 128 resolution image samples exhibiting global coherence. We expand on previous work for image quality assessment to provide two new analyses for assessing the discriminability and diversity of samples from class-conditional image synthesis models. These analyses demonstrate that high resolution samples provide class information not present in low resolution samples. Across 1000 ImageNet classes, 128 × 128 samples are more than twice as discriminable as artificially resized 32 × 32 samples. In addition, 84.7% of the classes have samples exhibiting diversity comparable to real ImageNet data.
