When a large language model (LLM) performs complex reasoning by chain of thought (CoT), it can be highly sensitive to individual mistakes. We have had to train verifiers to address this issue. As we all know, after human inferring a conclusion, they often check it by re-verifying it, which can avoid some mistakes. We propose a new method called self-verification that uses the conclusion of the CoT as a condition to build a new sample and asks the LLM to re-predict the original conditions which be masked. We calculate an explainable verification score based on the accuracy. This method can improve the accuracy of multiple arithmetics and logical reasoning datasets when using few-shot learning. we have demonstrated that LLMs can conduct explainable self-verification of their own conclusions and achieve competitive reasoning performance. Extensive experimentals have demonstrated that our method can help multiple large language models with self-verification can avoid interference from incorrect CoT.

The number of international benchmarking competitions is steadily increasing in various fields of machine learning (ML) research and practice. So far, however, little is known about the common practice as well as bottlenecks faced by the community in tackling the research questions posed. To shed light on the status quo of algorithm development in the specific field of biomedical imaging analysis, we designed an international survey that was issued to all participants of challenges conducted in conjunction with the IEEE ISBI 2021 and MICCAI 2021 conferences (80 competitions in total). The survey covered participants' expertise and working environments, their chosen strategies, as well as algorithm characteristics. A median of 72% challenge participants took part in the survey. According to our results, knowledge exchange was the primary incentive (70%) for participation, while the reception of prize money played only a minor role (16%). While a median of 80 working hours was spent on method development, a large portion of participants stated that they did not have enough time for method development (32%). 25% perceived the infrastructure to be a bottleneck. Overall, 94% of all solutions were deep learning-based. Of these, 84% were based on standard architectures. 43% of the respondents reported that the data samples (e.g., images) were too large to be processed at once. This was most commonly addressed by patch-based training (69%), downsampling (37%), and solving 3D analysis tasks as a series of 2D tasks. K-fold cross-validation on the training set was performed by only 37% of the participants and only 50% of the participants performed ensembling based on multiple identical models (61%) or heterogeneous models (39%). 48% of the respondents applied postprocessing steps.

Recently, the success of pre-training in text domain has been fully extended to vision, audio, and cross-modal scenarios. The proposed pre-training models of different modalities are showing a rising trend of homogeneity in their model structures, which brings the opportunity to implement different pre-training models within a uniform framework. In this paper, we present TencentPretrain, a toolkit supporting pre-training models of different modalities. The core feature of TencentPretrain is the modular design. The toolkit uniformly divides pre-training models into 5 components: embedding, encoder, target embedding, decoder, and target. As almost all of common modules are provided in each component, users can choose the desired modules from different components to build a complete pre-training model. The modular design enables users to efficiently reproduce existing pre-training models or build brand-new one. We test the toolkit on text, vision, and audio benchmarks and show that it can match the performance of the original implementations.

Energy management systems (EMS) are becoming increasingly important in order to utilize the continuously growing curtailed renewable energy. Promising energy storage systems (ESS), such as batteries and green hydrogen should be employed to maximize the efficiency of energy stakeholders. However, optimal decision-making, i.e., planning the leveraging between different strategies, is confronted with the complexity and uncertainties of large-scale problems. Here, we propose a sophisticated deep reinforcement learning (DRL) methodology with a policy-based algorithm to realize the real-time optimal ESS planning under the curtailed renewable energy uncertainty. A quantitative performance comparison proved that the DRL agent outperforms the scenario-based stochastic optimization (SO) algorithm, even with a wide action and observation space. Owing to the uncertainty rejection capability of the DRL, we could confirm a robust performance, under a large uncertainty of the curtailed renewable energy, with a maximizing net profit and stable system. Action-mapping was performed for visually assessing the action taken by the DRL agent according to the state. The corresponding results confirmed that the DRL agent learns the way like what a human expert would do, suggesting reliable application of the proposed methodology.

Convolutional Neural Networks (CNNs) have demonstrated superiority in learning patterns, but are sensitive to label noises and may overfit noisy labels during training. The early stopping strategy averts updating CNNs during the early training phase and is widely employed in the presence of noisy labels. Motivated by biological findings that the amplitude spectrum (AS) and phase spectrum (PS) in the frequency domain play different roles in the animal's vision system, we observe that PS, which captures more semantic information, can increase the robustness of DNNs to label noise, more so than AS can. We thus propose early stops at different times for AS and PS by disentangling the features of some layer(s) into AS and PS using Discrete Fourier Transform (DFT) during training. Our proposed Phase-AmplituDe DisentangLed Early Stopping (PADDLES) method is shown to be effective on both synthetic and real-world label-noise datasets. PADDLES outperforms other early stopping methods and obtains state-of-the-art performance.

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.

在现实世界中的问题回答场景中，将表格和文本内容均结合的混合形式吸引了越来越多的关注，其中数值推理问题是最典型和最具挑战性的问题之一。现有方法通常采用编码器框架来表示混合内容并生成答案。但是，它无法捕获编码器侧数值，表格架构和文本信息之间的丰富关系。解码器使用一个简单的预定义运算符分类器，该分类器的灵活性不足以处理具有不同表达式的数值推理过程。为了解决这些问题，本文提出了一个\ textbf {re} lational \ textbf {g} raph增强\ textbf {h} ybrid table-text \ textbf {n}带有\ textbf {t textbf {t text} ree decoder（\ textbff recoder（\ textbf） {reghnt}）。它模拟了对表 - 文本混合内容的回答的数值问题，作为表达树的生成任务。此外，我们提出了一种新颖的关系图建模方法，该方法模拟了问题，表和段落之间的对齐方式。我们验证了公开可用的Table-Text混合质量质量质量标准（TAT-QA）的模型。拟议的reghnt显着胜过基线模型，并实现最新结果\脚注{我们在〜\ url {https://github.com/lfy79001/reghnt}}}〜（20222）公开发布了源代码和数据-05-05）。

模型不匹配在现实世界应用中占上风。因此，为具有不确定动态模型的系统设计可靠的安全控制算法很重要。主要的挑战是，不确定性导致难以实时寻找可行的安全控制。现有方法通常简化了问题，例如限制不确定性类型，忽略控制限制或放弃可行性保证。在这项工作中，我们通过为有限国家依赖性的不确定性提出一个强大的安全控制框架来克服这些问题。我们首先通过学习控制控制限制，不确定的安全性索引来保证安全控制不确定动态的可行性。然后，我们证明可以将稳健的安全控制作为凸问题（凸度半侵入编程或二阶锥编程）配制，并提出可以实时运行的相应最佳求解器。此外，我们分析了在未建模的不确定性下何时以及如何保留安全性。实验结果表明，我们的方法成功地发现了针对不同的不确定性实时的可靠安全控制，并且比强大的基线算法要保守得多。

神经文本排名模型已经见证了显着的进步，并越来越多地在实践中部署。不幸的是，它们还继承了一般神经模型的对抗性脆弱性，这些神经模型已被检测到，但仍未被先前的研究所忽视。此外，Blackhat SEO可能会利用继承的对抗性漏洞来击败受保护的搜索引擎。在这项研究中，我们提出了对黑盒神经通道排名模型的模仿对抗攻击。我们首先表明，可以通过列举关键查询/候选者，然后训练排名模仿模型来透明和模仿目标段落排名模型。利用排名模仿模型，我们可以精心操纵排名结果并将操纵攻击转移到目标排名模型。为此，我们提出了一种由成对目标函数授权的基于创新的基于梯度的攻击方法，以产生对抗性触发器，该触发器会导致有预谋的混乱，而具有很少的令牌。为了配备触发器的伪装，我们将下一个句子预测损失和语言模型流利度限制添加到目标函数中。对通过排名的实验结果证明了对各种SOTA神经排名模型的排名模仿攻击模型和对抗触发器的有效性。此外，各种缓解分析和人类评估表明，在面对潜在的缓解方法时，伪装的有效性。为了激励其他学者进一步研究这一新颖和重要的问题，我们将实验数据和代码公开可用。
