GPT-3 在多个 NLP 数据集上取得了强劲表现,包括翻译、问答和完形填空任务,以及若干需要即时推理或领域适应的任务,例如乱序词重组、在句子中使用新词、或执行三位数算术运算。GPT-3 achieves strong performance on many NLP datasets, including translation, question-answering, and cloze tasks, as well as several tasks that require on-the-fly reasoning or domain adaptation, such as unscrambling words, using a novel word in a sentence, or performing 3-digit arithmetic.

本文提出了一种新的解码策略——self-consistency,用于替代思维链 prompt 中使用的朴素贪心解码:首先采样一组多样化的推理路径,而非仅取贪心路径,然后通过对采样路径进行边缘化来选择最一致的答案。This paper proposes a new decoding strategy, self-consistency, to replace the naive greedy decoding used in chain-of-thought prompting that first samples a diverse set of reasoning paths instead of only taking the greedy one, and then selects the most consistent answer by marginalizing out the sampled reasoning paths.
在三种大语言模型上的实验表明,思维链提示能够在一系列算术、常识和符号推理任务上提升性能。Experiments on three large language models show that chain of thought prompting improves performance on a range of arithmetic, commonsense, and symbolic reasoning tasks.
本工作提出两种参数削减技术以降低 BERT 的内存占用并提升训练速度,并采用一种聚焦于建模句子间连贯性的自监督损失。This work presents two parameter-reduction techniques to lower memory consumption and increase the training speed of BERT, and uses a self-supervised loss that focuses on modeling inter-sentence coherence.
这项系统性研究在数十项语言理解任务上比较了预训练目标、架构、无标注数据集、迁移方法及其他因素,并在涵盖摘要、问答、文本分类等的许多基准上取得了 SOTA 结果。This systematic study compares pre-training objectives, architectures, unlabeled datasets, transfer approaches, and other factors on dozens of language understanding tasks and achieves state-of-the-art results on many benchmarks covering summarization, question answering, text classification, and more.
本文提出了 mixup,一种通过对样本对及其标签的凸组合来训练神经网络的简单学习原则,提升了 SOTA 神经网络架构的泛化能力。This work proposes mixup, a simple learning principle that trains a neural network on convex combinations of pairs of examples and their labels, which improves the generalization of state-of-the-art neural network architectures.
本文提出了一种双时间尺度更新规则(TTUR),用于在任意 GAN 损失函数下使用 SGD 训练 GAN,并引入了 Frechet Inception Distance(FID),相比 Inception Score 能更好地捕捉生成图像与真实图像之间的相似性。This work proposes a two time-scale update rule (TTUR) for training GANs with stochastic gradient descent on arbitrary GAN loss functions and introduces the "Frechet Inception Distance" (FID) which captures the similarity of generated images to real ones better than the Inception Score.
