门控相机作为扫描LIDAR传感器的替代方案，具有高分辨率的3D深度，在雾，雪和雨中稳健。不是通过光子飞行时间顺序地扫描场景并直接记录深度，如在脉冲激光雷达传感器中，所设定的成像器编码在百万像素分辨率的少量门控切片中的相对强度的深度。尽管现有方法表明，可以从这些测量中解码高分辨率深度，但这些方法需要同步和校准的LIDAR来监督门控深度解码器 - 禁止在地理位置上快速采用，在大型未配对数据集上培训，以及探索替代应用程序外面的汽车用例。在这项工作中，我们填补了这个差距并提出了一种完全自我监督的深度估计方法，它使用门控强度配置文件和时间一致性作为训练信号。所提出的模型从门控视频序列培训结束到结束，不需要LIDAR或RGB数据，并学会估计绝对深度值。我们将门控切片作为输入和解散估计场景，深度和环境光，然后用于学习通过循环损耗来重建输入切片。我们依赖于给定帧和相邻门控切片之间的时间一致性，以在具有阴影和反射的区域中估计深度。我们通过实验验证，所提出的方法优于基于单眼RGB和立体图像的现有监督和自我监督的深度估计方法，以及基于门控图像的监督方法。

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

联合学习（FL）是一种使用跨设备分布的数据训练模型的技术。差异隐私（DP）为敏感数据提供了正式的隐私保证。我们的目标是在使用FL和DP保护隐私的同时，在计算受限设备上训练大型神经网络语言模型（NNLM）。但是，随着模型大小的增长，引入模型的DP噪声增加，这通常会阻止收敛。我们提出了部分嵌入更新（PEU），这是一种新颖的技术，可以通过降低有效载荷大小来降低噪声。此外，我们采用低级适应（LORA）和噪声对比估计（NCE）来减少计算受限设备上大型模型的记忆需求。这种技术的组合使得可以在保留准确性和隐私的同时训练大型唱机语言模型。

大型神经模型的培训和推断很昂贵。但是，对于许多应用程序域，虽然新任务和模型经常出现，但建模的基础文档主要保持不变。我们研究如何通过嵌入回收利用（ER）来降低此类设置的计算成本：在执行训练或推理时从以前的模型中重新使用激活。与以前的工作相反，重点是冻结小型分类头进行填充，这通常会导致绩效显着下降，我们提出了从预告片的模型中缓存中间层的输出，并为新任务的剩余层进行填充。我们表明，我们的方法在训练过程中提供了100％的速度和55-86％的推理，并且对科学领域中文本分类和实体识别任务的准确性产生了可观的影响。对于通用域的问答任务，ER提供了类似的加速和少量准确性。最后，我们确定了ER的几个开放挑战和未来的方向。

最先进的愿景和愿景和语言模型依靠大规模的Visio-linguisting预借鉴，以获得各种下游任务的良好性能。通常，这种模型通常是跨模态（对比）或多模态（具有早期融合）但不是两者;它们通常只针对特定的方式或任务。有希望的方向将是使用单一整体普遍模型，作为“基础”，目标是一次性的所有方式 - 真正的视觉和语言基础模型应该擅长视力任务，语言任务和交叉和多数模态视觉和语言任务。我们将Flava介绍在这样的模型中，并在跨越这些目标模式的广泛的35个任务上展示令人印象深刻的性能。

In the last year, new models and methods for pretraining and transfer learning have driven striking performance improvements across a range of language understanding tasks. The GLUE benchmark, introduced a little over one year ago, offers a single-number metric that summarizes progress on a diverse set of such tasks, but performance on the benchmark has recently surpassed the level of non-expert humans, suggesting limited headroom for further research. In this paper we present SuperGLUE, a new benchmark styled after GLUE with a new set of more difficult language understanding tasks, a software toolkit, and a public leaderboard. SuperGLUE is available at super.gluebenchmark.com.

This paper investigates the ability of artificial neural networks to judge the grammatical acceptability of a sentence, with the goal of testing their linguistic competence. We introduce the Corpus of Linguistic Acceptability (CoLA), a set of 10,657 English sentences labeled as grammatical or ungrammatical from published linguistics literature. As baselines, we train several recurrent neural network models on acceptability classification, and find that our models outperform unsupervised models by Lau et al. (2016) on CoLA. Error-analysis on specific grammatical phenomena reveals that both Lau et al.'s models and ours learn systematic generalizations like subject-verb-object order. However, all models we test perform far below human level on a wide range of grammatical constructions.

For natural language understanding (NLU) technology to be maximally useful, it must be able to process language in a way that is not exclusive to a single task, genre, or dataset. In pursuit of this objective, we introduce the General Language Understanding Evaluation (GLUE) benchmark, a collection of tools for evaluating the performance of models across a diverse set of existing NLU tasks. By including tasks with limited training data, GLUE is designed to favor and encourage models that share general linguistic knowledge across tasks. GLUE also includes a hand-crafted diagnostic test suite that enables detailed linguistic analysis of models. We evaluate baselines based on current methods for transfer and representation learning and find that multi-task training on all tasks performs better than training a separate model per task. However, the low absolute performance of our best model indicates the need for improved general NLU systems.
