Interview has been regarded as one of the most crucial step for recruitment. To fully prepare for the interview with the recruiters, job seekers usually practice with mock interviews between each other. However, such a mock interview with peers is generally far away from the real interview experience: the mock interviewers are not guaranteed to be professional and are not likely to behave like a real interviewer. Due to the rapid growth of online recruitment in recent years, recruiters tend to have online interviews, which makes it possible to collect real interview data from real interviewers. In this paper, we propose a novel application named EZInterviewer, which aims to learn from the online interview data and provides mock interview services to the job seekers. The task is challenging in two ways: (1) the interview data are now available but still of low-resource; (2) to generate meaningful and relevant interview dialogs requires thorough understanding of both resumes and job descriptions. To address the low-resource challenge, EZInterviewer is trained on a very small set of interview dialogs. The key idea is to reduce the number of parameters that rely on interview dialogs by disentangling the knowledge selector and dialog generator so that most parameters can be trained with ungrounded dialogs as well as the resume data that are not low-resource. Evaluation results on a real-world job interview dialog dataset indicate that we achieve promising results to generate mock interviews. With the help of EZInterviewer, we hope to make mock interview practice become easier for job seekers.

Deep neural networks are incredibly vulnerable to crafted, human-imperceptible adversarial perturbations. Although adversarial training (AT) has proven to be an effective defense approach, we find that the AT-trained models heavily rely on the input low-frequency content for judgment, accounting for the low standard accuracy. To close the large gap between the standard and robust accuracies during AT, we investigate the frequency difference between clean and adversarial inputs, and propose a frequency regularization (FR) to align the output difference in the spectral domain. Besides, we find Stochastic Weight Averaging (SWA), by smoothing the kernels over epochs, further improves the robustness. Among various defense schemes, our method achieves the strongest robustness against attacks by PGD-20, C\&W and Autoattack, on a WideResNet trained on CIFAR-10 without any extra data.

Most multimodal multi-objective evolutionary algorithms (MMEAs) aim to find all global Pareto optimal sets (PSs) for a multimodal multi-objective optimization problem (MMOP). However, in real-world problems, decision makers (DMs) may be also interested in local PSs. Also, searching for both global and local PSs is more general in view of dealing with MMOPs, which can be seen as a generalized MMOP. In addition, the state-of-the-art MMEAs exhibit poor convergence on high-dimension MMOPs. To address the above two issues, in this study, a novel coevolutionary framework termed CoMMEA for multimodal multi-objective optimization is proposed to better obtain both global and local PSs, and simultaneously, to improve the convergence performance in dealing with high-dimension MMOPs. Specifically, the CoMMEA introduces two archives to the search process, and coevolves them simultaneously through effective knowledge transfer. The convergence archive assists the CoMMEA to quickly approaching the Pareto optimal front (PF). The knowledge of the converged solutions is then transferred to the diversity archive which utilizes the local convergence indicator and the $\epsilon$-dominance-based method to obtain global and local PSs effectively. Experimental results show that CoMMEA is competitive compared to seven state-of-the-art MMEAs on fifty-four complex MMOPs.

Error correction in automatic speech recognition (ASR) aims to correct those incorrect words in sentences generated by ASR models. Since recent ASR models usually have low word error rate (WER), to avoid affecting originally correct tokens, error correction models should only modify incorrect words, and therefore detecting incorrect words is important for error correction. Previous works on error correction either implicitly detect error words through target-source attention or CTC (connectionist temporal classification) loss, or explicitly locate specific deletion/substitution/insertion errors. However, implicit error detection does not provide clear signal about which tokens are incorrect and explicit error detection suffers from low detection accuracy. In this paper, we propose SoftCorrect with a soft error detection mechanism to avoid the limitations of both explicit and implicit error detection. Specifically, we first detect whether a token is correct or not through a probability produced by a dedicatedly designed language model, and then design a constrained CTC loss that only duplicates the detected incorrect tokens to let the decoder focus on the correction of error tokens. Compared with implicit error detection with CTC loss, SoftCorrect provides explicit signal about which words are incorrect and thus does not need to duplicate every token but only incorrect tokens; compared with explicit error detection, SoftCorrect does not detect specific deletion/substitution/insertion errors but just leaves it to CTC loss. Experiments on AISHELL-1 and Aidatatang datasets show that SoftCorrect achieves 26.1% and 9.4% CER reduction respectively, outperforming previous works by a large margin, while still enjoying fast speed of parallel generation.

Adversarial training is one of the most powerful methods to improve the robustness of pre-trained language models (PLMs). However, this approach is typically more expensive than traditional fine-tuning because of the necessity to generate adversarial examples via gradient descent. Delving into the optimization process of adversarial training, we find that robust connectivity patterns emerge in the early training phase (typically $0.15\sim0.3$ epochs), far before parameters converge. Inspired by this finding, we dig out robust early-bird tickets (i.e., subnetworks) to develop an efficient adversarial training method: (1) searching for robust tickets with structured sparsity in the early stage; (2) fine-tuning robust tickets in the remaining time. To extract the robust tickets as early as possible, we design a ticket convergence metric to automatically terminate the searching process. Experiments show that the proposed efficient adversarial training method can achieve up to $7\times \sim 13 \times$ training speedups while maintaining comparable or even better robustness compared to the most competitive state-of-the-art adversarial training methods.

Recent works on Lottery Ticket Hypothesis have shown that pre-trained language models (PLMs) contain smaller matching subnetworks(winning tickets) which are capable of reaching accuracy comparable to the original models. However, these tickets are proved to be notrobust to adversarial examples, and even worse than their PLM counterparts. To address this problem, we propose a novel method based on learning binary weight masks to identify robust tickets hidden in the original PLMs. Since the loss is not differentiable for the binary mask, we assign the hard concrete distribution to the masks and encourage their sparsity using a smoothing approximation of L0 regularization.Furthermore, we design an adversarial loss objective to guide the search for robust tickets and ensure that the tickets perform well bothin accuracy and robustness. Experimental results show the significant improvement of the proposed method over previous work on adversarial robustness evaluation.

强有力的对手例子是评估和增强深神经网络鲁棒性的关键。流行的对抗性攻击算法使用梯度上升最大化非cave损失函数。但是，每种攻击的性能通常对由于信息不足（仅一个输入示例，几乎没有白色盒子源模型和未知的防御策略）而敏感。因此，精心设计的对抗性示例容易过度拟合源模型，从而将其转移性限制在身份不明的架构上。在本文中，我们提出了多种渐近正态分布攻击（Multianda），这是一种新颖的方法，可以明确表征来自学习分布的对抗性扰动。具体而言，我们通过利用随机梯度上升（SGA）的渐近正态性能（SGA）的优势来近似于扰动，然后将整体策略应用于此过程，以估算高斯混合模型，以更好地探索潜在的优化空间。从学习分布中绘制扰动使我们能够为每个输入生成任何数量的对抗示例。近似后验实质上描述了SGA迭代的固定分布，该分布捕获了局部最佳距离周围的几何信息。因此，从分布中得出的样品可靠地保持转移性。我们提出的方法通过对七个正常训练和七个防御模型进行广泛的实验，超过了对具有或没有防御的深度学习模型的九个最先进的黑盒攻击。

许多最新的自然语言任务方法都建立在大型语言模型的非凡能力上。大型语言模型可以执行内在的学习，他们可以从几个任务演示中学习新任务，而无需任何参数更新。这项工作研究了对新自然语言任务的数据集创建数据集的含义。与最近的文化学习方法背道而驰，我们制定了一个注释效率的两步框架：选择性注释，选择一个示例池，以提前从未标记的数据中从未标记的数据中进行注释，然后及时检索从注释的池中检索任务示例测试时间。基于此框架，我们提出了一种无监督的，基于图的选择性注释方法VOKE-K，以选择各种代表性的示例进行注释。在10个数据集上进行了广泛的实验（涵盖分类，常识性推理，对话和文本/代码生成）表明，我们的选择性注释方法通过很大的利润提高了任务性能。与随机选择示例进行注释相比，Pote-K平均在注释预算下获得了12.9％/11.4％的相对增益。与最先进的监督登录方法相比，它的性能相似，而在10个任务中的注释成本降低了10-100倍。我们在各种情况下进一步分析了框架的有效性：具有不同大小的语言模型，替代选择性注释方法以及有测试数据域移动的情况。我们希望我们的研究将作为数据注释的基础，因为大型语言模型越来越多地应用于新任务。我们的代码可在https://github.com/hkunlp/icl-selactive-annotation上找到。

我们介绍了一项对自然语言（NL）推理的人类通知，开放域和逻辑上复杂且多样的数据集，配备了一阶逻辑（fol）注释。对开本由1,435个示例（独特的结论）组成，每个示例与487组前提之一搭配，这些场所作为规则，可用于演绎理由，以理解每个结论的有效性。前提和结论的逻辑正确性是通过其平行注释来确保的，这些注释会自动由我们的FOL推理引擎验证。除了主要的NL推理任务外，对开本中的NL-FOL对自动构成了使用FOL作为逻辑形式的新的NL-FOL翻译数据集。我们对广泛的实验系统地评估了对中型语言模型（BERT，ROBERTA）进行微调的FOL推理能力，并且在大型语言模型（GPT-NEOX，OPT，OPT，GPT-3，Codex）上促成了很少的射击。对于NL-FOL翻译，我们尝试使用GPT-3和Codex。我们的结果表明，公开可用的最强大的大语言模型之一（LLM），GPT-3 Davinci，仅比随机结果略好，而在一部分集的一部分中，该模型尤其不好，并且在预测该模型方面尤其不好。纠正虚假和未知结论的真实价值。我们的数据集和代码可在https://github.com/yale-lily/folio上找到。

歌词到融合的生成是歌曲创作的重要任务，并且由于其独特的特征也很具有挑战性：产生的旋律不仅应遵循良好的音乐模式，而且还应与节奏和结构等歌词中的功能保持一致。由于几个问题，这些特征无法通过以端到端学习抒情式映射的神经生成模型来很好地处理：（1）缺乏对齐的抒情式摩托律训练数据，以充分学习抒情液特征结盟; （2）发电中缺乏可控性，无法明确保证抒情特征对齐。在本文中，我们提出了ROC，这是一种新的抒情术的范式，该范式通过一代网络式管道解决了上述问题。具体而言，我们的范式有两个阶段：（1）创建阶段，其中大量音乐是由基于神经的旋律语言模型生成的，并通过几个关键功能（例如和弦，音调，节奏和节奏和节奏）在数据库中索引。结构信息，包括合唱或经文）； （2）重新创建阶段，根据歌词的关键功能从数据库中检索音乐作品，并根据构图指南和旋律语言模型分数从数据库中检索音乐作品来重新创建旋律。我们的ROC范式具有多个优点：（1）它只需要未配对的旋律数据来训练旋律语言模型，而不是以前模型中配对的抒情数据。 （2）它在抒情循环的生成中实现了良好的抒情式特征对齐。关于英语和中文数据集的实验表明，ROC在客观和主观指标上都优于先前基于神经的抒情性循环模型。
