在这项工作中，我们提出了一个端到端双耳语音合成系统，该系统将低抑制音频编解码器与强大的双耳解码器结合在一起，该解码器能够准确地进行语音双耳化，同时忠实地重建环境因素，例如环境噪声或混响。该网络是经过修改的矢量定量变异自动编码器，经过训练，采用了几个精心设计的目标，包括对抗性损失。我们在具有客观指标和感知研究的内部双耳数据集上评估了所提出的系统。结果表明，所提出的方法比以前的方法更接近地面真相数据。特别是，我们证明了对抗性损失在捕获创建真实听觉场景所需的环境效果中的能力。

As language models (LMs) scale, they develop many novel behaviors, good and bad, exacerbating the need to evaluate how they behave. Prior work creates evaluations with crowdwork (which is time-consuming and expensive) or existing data sources (which are not always available). Here, we automatically generate evaluations with LMs. We explore approaches with varying amounts of human effort, from instructing LMs to write yes/no questions to making complex Winogender schemas with multiple stages of LM-based generation and filtering. Crowdworkers rate the examples as highly relevant and agree with 90-100% of labels, sometimes more so than corresponding human-written datasets. We generate 154 datasets and discover new cases of inverse scaling where LMs get worse with size. Larger LMs repeat back a dialog user's preferred answer ("sycophancy") and express greater desire to pursue concerning goals like resource acquisition and goal preservation. We also find some of the first examples of inverse scaling in RL from Human Feedback (RLHF), where more RLHF makes LMs worse. For example, RLHF makes LMs express stronger political views (on gun rights and immigration) and a greater desire to avoid shut down. Overall, LM-written evaluations are high-quality and let us quickly discover many novel LM behaviors.

在本文中，我们提出了一个新的基于聚类的主动学习框架，即使用基于聚类的采样（ALCS）的主动学习，以解决标记数据的短缺。ALCS采用基于密度的聚类方法来探索数据集群结构，而无需详尽的参数调整。引入了基于双簇边界的样本查询过程，以提高对高度重叠类分类的学习绩效。此外，我们制定了一种有效的多样性探索策略，以解决查询样品之间的冗余。我们的实验结果证明了ALCS方法的疗效。

我们审查当前的解决方案和技术挑战，以实现自动语音识别，关键字发现，设备仲裁，语音增强和在多边形家庭环境中的来源本地化，以为Interspeech 2022特别会议提供背景，“信号处理和机器学习的挑战和机器，用于多个智能设备”。我们还确定了支持这些研究领域所需的数据集。根据评论和我们在多设备领域的研究经验，我们以对未来进化的前景结论

学习异质治疗效果（HTE）是许多领域的重要问题。大多数现有方法都使用单个治疗组和单个结果指标来考虑设置。但是，在许多现实世界中，实验始终如一 - 例如，在互联网公司中，每天进行A/B测试，以衡量许多感兴趣的不同指标的潜在变化的影响。我们表明，即使一个分析师在一个实验中仅关心HTES来实现一个指标，也可以通过共同分析所有数据来利用交叉实验和交叉结果度量相关性来大大提高精度。我们在张量分解框架中对这个想法进行形式化，并提出了一个简单且可扩展的模型，我们称之为低级或LR-LR-LERNER。合成数据和实际数据的实验表明，LR-LEARNER可以比独立的HTE估计更精确。

在本文中，我们提出了一种简单的面向事件的算法，用于通过事件摄像机的新技术检测具有已知频率的像素大小的信号。此外，我们分析了算法从随机波动中滤除所需的周期性信号的能力。我们证明了这种能力，并展示了算法如何在暮光期间区分闪烁的路灯的信号，该路线的频率为100 Hz，而太阳闪光源自视野中遥远的建筑物的窗户。

MARCO排名数据集已广泛用于培训IR任务的深度学习模型，在不同的零射击方案上实现了相当大的效果。但是，这种类型的资源是英语以外的语言的稀缺。在这项工作中，我们呈现MMARCO，MS Marco段落的多语言版本，该数据集包括使用机器翻译创建的13种语言。我们通过微调单语和多语言重新排名模型以及此数据集的密集多语言模型进行了评估。实验结果表明，在我们翻译的数据集上微调微调的多语言模型可以单独对原始英文版的模型进行微调的卓越效果。我们蒸馏的多语言RE-RANKER与非蒸馏模型具有竞争力，而参数较少的5.4倍。最后，我们展现了翻译质量和检索效果之间的正相关性，提供了证据，即翻译方法的改进可能导致多语言信息检索的改进。翻译的数据集和微调模型可在https://github.com/unicamp-dl/mmarco.git上获得。

Trained machine learning models are increasingly used to perform high-impact tasks in areas such as law enforcement, medicine, education, and employment. In order to clarify the intended use cases of machine learning models and minimize their usage in contexts for which they are not well suited, we recommend that released models be accompanied by documentation detailing their performance characteristics. In this paper, we propose a framework that we call model cards, to encourage such transparent model reporting. Model cards are short documents accompanying trained machine learning models that provide benchmarked evaluation in a variety of conditions, such as across different cultural, demographic, or phenotypic groups (e.g., race, geographic location, sex, Fitzpatrick skin type [15]) and intersectional groups (e.g., age and race, or sex and Fitzpatrick skin type) that are relevant to the intended application domains. Model cards also disclose the context in which models are intended to be used, details of the performance evaluation procedures, and other relevant information. While we focus primarily on human-centered machine learning models in the application fields of computer vision and natural language processing, this framework can be used to document any trained machine learning model. To solidify the concept, we provide cards for two supervised models: One trained to detect smiling faces in images, and one trained to detect toxic comments in text. We propose model cards as a step towards the responsible democratization of machine learning and related artificial intelligence technology, increasing transparency into how well artificial intelligence technology works. We hope this work encourages those releasing trained machine learning models to accompany model releases with similar detailed evaluation numbers and other relevant documentation.

机器学习社区目前没有记录数据集的标准化过程，这可能导致高赌注域的严重后果。要解决此差距，我们提出了数据集的数据表。在电子行业，每个组件，无论多么简单或复杂，都附带了一个描述其操作特征，测试结果，推荐使用和其他信息的数据表。通过类比，我们建议每个数据集都附有一个数据表，这些表记录了它的动机，组成，收集过程，推荐用途等。数据集的数据表将有助于在数据集创建者和数据集消费者之间更好地沟通，并鼓励机器学习界优先考虑透明度和问责制。
