The stock market prediction has been a traditional yet complex problem researched within diverse research areas and application domains due to its non-linear, highly volatile and complex nature. Existing surveys on stock market prediction often focus on traditional machine learning methods instead of deep learning methods. Deep learning has dominated many domains, gained much success and popularity in recent years in stock market prediction. This motivates us to provide a structured and comprehensive overview of the research on stock market prediction focusing on deep learning techniques. We present four elaborated subtasks of stock market prediction and propose a novel taxonomy to summarize the state-of-the-art models based on deep neural networks from 2011 to 2022. In addition, we also provide detailed statistics on the datasets and evaluation metrics commonly used in the stock market. Finally, we highlight some open issues and point out several future directions by sharing some new perspectives on stock market prediction.

认识到人类的感情在日常沟通中发挥着关键作用。神经科学已经证明，不同的情绪状态存在于不同脑区，脑电图频带和颞戳中不同程度的激活。在本文中，我们提出了一种新颖的结构来探索情感认可的信息脑电图。所提出的模块，由PST-Integn表示，由位置，光谱和颞件注意力模块组成，用于探索更多辨别性EEG特征。具体地，位置注意模块是捕获在空间尺寸中的不同情绪刺激的激活区域。光谱和时间注意力模块分别分配不同频带和时间片的权重。我们的方法是自适应的，也可以符合其作为插入式模块的3D卷积神经网络（3D-CNN）。我们在两个现实世界数据集进行实验。 3D-CNN结合我们的模块实现了有希望的结果，并证明了PST-关注能够从脑电图中捕获稳定的情感识别模式。

脑电图（EEG）是情绪识别的流行和有效工具。但是，研究人员仍然晦涩难懂，人脑中脑电图中脑电图的传播机制及其与情绪的内在相关性仍然晦涩难懂。这项工作提出了四个变体变压器框架〜（空间注意力，暂时关注，顺序的时空注意力和同时的空间临时注意），以探索情感与空间 - 周期性的EEG特征之间的关系。具体而言，空间注意力和时间关注是分别学习拓扑结构信息和时间变化的脑电图特征。顺序的时空注意力在一秒钟的段中引起空间注意力，并在一个样本中依次在一个样本中注意，以探索情绪刺激对同一时间段中不同EEG电极EEG电极的EEG信号的影响程度。同时进行空间和时间关注的同时时空注意力同时进行，用于模拟不同时间段中不同空间特征之间的关系。实验结果表明，同时的时空注意力会导致设计选择中的最佳情感识别精度，这表明建模EEG信号的空间和时间特征的相关性对于情绪识别是重要的。

使用脚压力/力量测量硬件和运动捕获（MOCAP）技术对人类稳定的定量评估昂贵，耗时，并且仅限于实验室（基于实验室）。我们提出了一种基于图像的新方法来估计稳定计算的三个关键组件：质量中心（COM），支持基础（BOS）和压力中心（COP）。此外，我们通过使用公共可用的多模式（MOCAP，脚压力，2视频视频），定量验证基于图像的方法来计算两种经典稳定度量，以直接从基于实验室的感觉输出（地面真相）产生的方法来计算两种经典稳定性措施。十个受试者人类运动数据集。我们的实验结果表明：1）我们的COM估计方法（COMNET）始终优于最先进的基于惯性传感器的COM估计技术； 2）我们基于图像的方法与单独的鞋垫脚压结合，与地面真相稳定性度量产生一致且具有统计学意义的相关性（comtocop r = 0.79 p <0.001，comtobos r = 0.75 p <0.001）; 3）我们完全基于图像的稳定性度量估计在两个稳定性指标上产生一致，正且具有统计学意义的相关性（ComtoCop r = 0.31 P <0.001，comtobos r = 0.22 P <0.001）。我们的研究为自然环境中的稳定性计算和监测提供了有希望的定量证据。

与传统的卷积神经网络（CNN）和视觉变压器不同，多层默认（MLP）是一种新的视觉模型，具有极其简单的架构，其仅由完全连接的层堆叠。 Vision MLP的输入图像通常被分成多个令牌（补丁），而现有的MLP模型直接用固定权重聚合它们，忽略来自不同图像的令牌的变化语义信息。为了动态聚合令牌，我们建议将每个令牌代表为具有两个部分，幅度和相位的波函数。幅度是原始特征，并且相位项是根据输入图像的语义内容改变的复值。介绍相位项可以动态调制MLP中令牌和固定权重之间的关系。基于波浪状令牌表示，我们建立了一种用于视觉任务的新型波-MLP架构。广泛的实验表明，所提出的波-MLP优于各种视觉任务的最先进的MLP架构，例如图像分类，对象检测和语义分割。

Compressed videos often exhibit visually annoying artifacts, known as Perceivable Encoding Artifacts (PEAs), which dramatically degrade video visual quality. Subjective and objective measures capable of identifying and quantifying various types of PEAs are critical in improving visual quality. In this paper, we investigate the influence of four spatial PEAs (i.e. blurring, blocking, bleeding, and ringing) and two temporal PEAs (i.e. flickering and floating) on video quality. For spatial artifacts, we propose a visual saliency model with a low computational cost and higher consistency with human visual perception. In terms of temporal artifacts, self-attention based TimeSFormer is improved to detect temporal artifacts. Based on the six types of PEAs, a quality metric called Saliency-Aware Spatio-Temporal Artifacts Measurement (SSTAM) is proposed. Experimental results demonstrate that the proposed method outperforms state-of-the-art metrics. We believe that SSTAM will be beneficial for optimizing video coding techniques.

As one of the most important psychic stress reactions, micro-expressions (MEs), are spontaneous and transient facial expressions that can reveal the genuine emotions of human beings. Thus, recognizing MEs (MER) automatically is becoming increasingly crucial in the field of affective computing, and provides essential technical support in lie detection, psychological analysis and other areas. However, the lack of abundant ME data seriously restricts the development of cutting-edge data-driven MER models. Despite the recent efforts of several spontaneous ME datasets to alleviate this problem, it is still a tiny amount of work. To solve the problem of ME data hunger, we construct a dynamic spontaneous ME dataset with the largest current ME data scale, called DFME (Dynamic Facial Micro-expressions), which includes 7,526 well-labeled ME videos induced by 671 participants and annotated by more than 20 annotators throughout three years. Afterwards, we adopt four classical spatiotemporal feature learning models on DFME to perform MER experiments to objectively verify the validity of DFME dataset. In addition, we explore different solutions to the class imbalance and key-frame sequence sampling problems in dynamic MER respectively on DFME, so as to provide a valuable reference for future research. The comprehensive experimental results show that our DFME dataset can facilitate the research of automatic MER, and provide a new benchmark for MER. DFME will be published via https://mea-lab-421.github.io.

Face Anti-spoofing (FAS) is essential to secure face recognition systems from various physical attacks. However, recent research generally focuses on short-distance applications (i.e., phone unlocking) while lacking consideration of long-distance scenes (i.e., surveillance security checks). In order to promote relevant research and fill this gap in the community, we collect a large-scale Surveillance High-Fidelity Mask (SuHiFiMask) dataset captured under 40 surveillance scenes, which has 101 subjects from different age groups with 232 3D attacks (high-fidelity masks), 200 2D attacks (posters, portraits, and screens), and 2 adversarial attacks. In this scene, low image resolution and noise interference are new challenges faced in surveillance FAS. Together with the SuHiFiMask dataset, we propose a Contrastive Quality-Invariance Learning (CQIL) network to alleviate the performance degradation caused by image quality from three aspects: (1) An Image Quality Variable module (IQV) is introduced to recover image information associated with discrimination by combining the super-resolution network. (2) Using generated sample pairs to simulate quality variance distributions to help contrastive learning strategies obtain robust feature representation under quality variation. (3) A Separate Quality Network (SQN) is designed to learn discriminative features independent of image quality. Finally, a large number of experiments verify the quality of the SuHiFiMask dataset and the superiority of the proposed CQIL.

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.

Nowadays, time-stamped web documents related to a general news query floods spread throughout the Internet, and timeline summarization targets concisely summarizing the evolution trajectory of events along the timeline. Unlike traditional document summarization, timeline summarization needs to model the time series information of the input events and summarize important events in chronological order. To tackle this challenge, in this paper, we propose a Unified Timeline Summarizer (UTS) that can generate abstractive and extractive timeline summaries in time order. Concretely, in the encoder part, we propose a graph-based event encoder that relates multiple events according to their content dependency and learns a global representation of each event. In the decoder part, to ensure the chronological order of the abstractive summary, we propose to extract the feature of event-level attention in its generation process with sequential information remained and use it to simulate the evolutionary attention of the ground truth summary. The event-level attention can also be used to assist in extracting summary, where the extracted summary also comes in time sequence. We augment the previous Chinese large-scale timeline summarization dataset and collect a new English timeline dataset. Extensive experiments conducted on these datasets and on the out-of-domain Timeline 17 dataset show that UTS achieves state-of-the-art performance in terms of both automatic and human evaluations.
