We present NusaCrowd, a collaborative initiative to collect and unite existing resources for Indonesian languages, including opening access to previously non-public resources. Through this initiative, we have has brought together 137 datasets and 117 standardized data loaders. The quality of the datasets has been assessed manually and automatically, and their effectiveness has been demonstrated in multiple experiments. NusaCrowd's data collection enables the creation of the first zero-shot benchmarks for natural language understanding and generation in Indonesian and its local languages. Furthermore, NusaCrowd brings the creation of the first multilingual automatic speech recognition benchmark in Indonesian and its local languages. Our work is intended to help advance natural language processing research in under-represented languages.

Dialogue systems can leverage large pre-trained language models and knowledge to generate fluent and informative responses. However, these models are still prone to produce hallucinated responses not supported by the input source, which greatly hinders their application. The heterogeneity between external knowledge and dialogue context challenges representation learning and source integration, and further contributes to unfaithfulness. To handle this challenge and generate more faithful responses, this paper presents RHO ($\rho$) utilizing the representations of linked entities and relation predicates from a knowledge graph (KG). We propose (1) local knowledge grounding to combine textual embeddings with the corresponding KG embeddings; and (2) global knowledge grounding to equip RHO with multi-hop reasoning abilities via the attention mechanism. In addition, we devise a response re-ranking technique based on walks over KG sub-graphs for better conversational reasoning. Experimental results on OpenDialKG show that our approach significantly outperforms state-of-the-art methods on both automatic and human evaluation by a large margin, especially in hallucination reduction (17.54% in FeQA).

Developing robust and fair AI systems require datasets with comprehensive set of labels that can help ensure the validity and legitimacy of relevant measurements. Recent efforts, therefore, focus on collecting person-related datasets that have carefully selected labels, including sensitive characteristics, and consent forms in place to use those attributes for model testing and development. Responsible data collection involves several stages, including but not limited to determining use-case scenarios, selecting categories (annotations) such that the data are fit for the purpose of measuring algorithmic bias for subgroups and most importantly ensure that the selected categories/subcategories are robust to regional diversities and inclusive of as many subgroups as possible. Meta, in a continuation of our efforts to measure AI algorithmic bias and robustness (https://ai.facebook.com/blog/shedding-light-on-fairness-in-ai-with-a-new-data-set), is working on collecting a large consent-driven dataset with a comprehensive list of categories. This paper describes our proposed design of such categories and subcategories for Casual Conversations v2.

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.

从图像中产生短篇小说是艰巨的。与图像字幕不同，来自图像的故事产生构成了多个挑战：保持故事连贯性，适当评估故事的质量，将生成的故事转向某种风格，并解决图像故事对的参考数据集的稀缺性，以限制训练期间的训练监督。在这项工作中，我们介绍了插件的故事讲述者（PPST），并通过以下方式改进图像到故事的生成：1）通过合并大型预培训模型，即剪辑和GPT-2来减轻数据稀缺问题，以促进通过最少的监督，流利的图像到文本一代，以及2）通过合并风格适配器来控制故事的生成，从而实现了更相关的一代。我们通过非风格，浪漫风格和动作风格的PPST进行图像到故事的生成实验，并将我们生成的故事与以前的故事进行比较三个方面的故事，即故事连贯性，图像故事相关性和风格和风格健身，使用自动和人类评估。结果表明，PPST提高了故事的连贯性，并且具有更好的图像故事相关性，但尚未充分风格。

随着深度学习和智能车辆的兴起，智能助手已成为促进驾驶和提供额外功能的重要车内组件。车内智能助手应该能够处理一般以及与汽车相关的命令并执行相应的操作，从而简化驾驶并提高安全性。但是，在这个研究领域，大多数数据集都采用主要语言，例如英语和中文。对于低资源语言，存在一个巨大的数据稀缺问题，阻碍了对更广泛社区的研究和应用的发展。因此，至关重要的是，拥有更多的基准来提高认识并激发低资源语言的研究。为了减轻此问题，我们收集了一个新的数据集，即广东话音频 - 视听语音识别（CI-AVSR），以使用视频和音频数据在广东话中使用拼写语言识别。与此同时，我们提出了广东话音频的语音识别在车内命令，这是社区在车内场景下应对低资源语音识别的新挑战。

语言模型既展示了定量的改进，又展示了新的定性功能，随着规模的增加。尽管它们具有潜在的变革性影响，但这些新能力的特征却很差。为了为未来的研究提供信息，为破坏性的新模型能力做准备，并改善社会有害的效果，至关重要的是，我们必须了解目前和近乎未来的能力和语言模型的局限性。为了应对这一挑战，我们介绍了超越模仿游戏基准（Big Bench）。 Big Bench目前由204个任务组成，由132家机构的442位作者贡献。任务主题是多样的，从语言学，儿童发展，数学，常识性推理，生物学，物理学，社会偏见，软件开发等等。 Big-Bench专注于被认为超出当前语言模型的功能的任务。我们评估了OpenAI的GPT型号，Google内部密集变压器体系结构和大型基础上的开关稀疏变压器的行为，跨越了数百万到数十亿个参数。此外，一个人类专家评估者团队执行了所有任务，以提供强大的基准。研究结果包括：模型性能和校准都随规模改善，但绝对的术语（以及与评估者的性能相比）；在模型类中的性能非常相似，尽管带有稀疏性。逐渐和预测的任务通常涉及大量知识或记忆成分，而在临界规模上表现出“突破性”行为的任务通常涉及多个步骤或组成部分或脆性指标；社交偏见通常会随着含糊不清的环境而随着规模而增加，但这可以通过提示来改善。

任务自适应预训练（TAPT）减轻了缺乏标记的数据，并通过将未标记的数据调整为下游任务来提供性能提升。不幸的是，现有的改编主要涉及不能很好地概括的确定性规则。在这里，我们提出了Clozer，这是一种基于TAPT中使用的基于序列的固定答案提取方法，可扩展，以适应任何固定的机器读数理解理解（MRC）下游任务。我们在多项选择披肩风格的MRC任务上进行了实验，并证明与Oracle和最先进的TAPT在提升模型性能中的效果相比，Clozer的性能要好得多，并证明Clozer能够识别Gold独立于任何启发式方法的答案。

Natural Language Generation (NLG) has improved exponentially in recent years thanks to the development of sequence-to-sequence deep learning technologies such as Transformer-based language models. This advancement has led to more fluent and coherent NLG, leading to improved development in downstream tasks such as abstractive summarization, dialogue generation and data-to-text generation. However, it is also apparent that deep learning based generation is prone to hallucinate unintended text, which degrades the system performance and fails to meet user expectations in many real-world scenarios. To address this issue, many studies have been presented in measuring and mitigating hallucinated texts, but these have never been reviewed in a comprehensive manner before. In this survey, we thus provide a broad overview of the research progress and challenges in the hallucination problem in NLG. The survey is organized into two parts: (1) a general overview of metrics, mitigation methods, and future directions; and (2) an overview of task-specific research progress on hallucinations in the following downstream tasks, namely abstractive summarization, dialogue generation, generative question answering, data-to-text generation, machine translation, and visual-language generation. This survey serves to facilitate collaborative efforts among researchers in tackling the challenge of hallucinated texts in NLG.

随着深度学习和智能车辆的兴起，智能助手已成为促进驾驶和提供额外功能的基本内部组件。汽车智能助理应该能够处理一般的和与汽车有关的命令，并执行相应的操作，减轻驾驶和提高安全性。但是，对于低资源语言存在数据稀缺问题，妨碍了研究和应用的发展。在本文中，我们介绍了一个新的DataSet，粤式视听语音识别（CI-AVSR），用于粤语中的车载命令识别，具有视频和音频数据。它由令人宣传的30个粤语发言者记录的200个车载命令的4,984个样本（8.3小时）组成。此外，我们使用常见的内部内部背景噪声增强我们的数据集来模拟真实环境，产生比收集的数据集大10倍。我们提供我们数据集的清洁和增强版本的详细统计信息。此外，我们实施了两个多模式基线以证明CI-AVSR的有效性。实验结果表明，利用视觉信号提高了模型的整体性能。虽然我们的最佳模型可以在清洁测试集上实现相当大的质量，但嘈杂数据的语音识别质量仍然是较差的，并且仍然是真正的车载语音识别系统的极其具有挑战性的任务。数据集和代码将在https://github.com/hltchkust/ci-avsr发布。
