视觉变压器（VITS）已成为各种视觉任务的流行结构和优于卷积神经网络（CNNS）。然而，这种强大的变形金机带来了巨大的计算负担。而这背后的基本障碍是排气的令牌到令牌比较。为了缓解这一点，我们深入研究Vit的模型属性，观察到VITS表现出稀疏关注，具有高令牌相似性。这直观地向我们介绍了可行的结构不可知的尺寸，令牌编号，以降低计算成本。基于这一探索，我们为香草vits提出了一种通用的自我切片学习方法，即坐下。具体而言，我们首先设计一种新颖的令牌减肥模块（TSM），可以通过动态令牌聚集来提高VIT的推理效率。不同于令牌硬滴，我们的TSM轻轻地集成了冗余令牌变成了更少的信息，可以在不切断图像中的鉴别性令牌关系的情况下动态缩放视觉注意。此外，我们介绍了一种简洁的密集知识蒸馏（DKD）框架，其密集地以柔性自动编码器方式传送无组织的令牌信息。由于教师和学生之间的结构类似，我们的框架可以有效地利用结构知识以获得更好的收敛性。最后，我们进行了广泛的实验来评估我们的坐姿。它展示了我们的方法可以通过1.7倍加速VITS，其精度下降可忽略不计，甚至在3.6倍上加速VITS，同时保持其性能的97％。令人惊讶的是，通过简单地武装LV-VIT与我们的坐线，我们在想象中实现了新的最先进的表现，超过了最近文学中的所有CNN和VITS。

A common scenario of Multilingual Neural Machine Translation (MNMT) is that each translation task arrives in a sequential manner, and the training data of previous tasks is unavailable. In this scenario, the current methods suffer heavily from catastrophic forgetting (CF). To alleviate the CF, we investigate knowledge distillation based life-long learning methods. Specifically, in one-tomany scenario, we propose a multilingual distillation method to make the new model (student) jointly learn multilingual output from old model (teacher) and new task. In many-to one scenario, we find that direct distillation faces the extreme partial distillation problem, and we propose two different methods to address it: pseudo input distillation and reverse teacher distillation. The experimental results on twelve translation tasks show that the proposed methods can better consolidate the previous knowledge and sharply alleviate the CF.

In recent years, deep-learning-based approaches have been introduced to solving time-series forecasting-related problems. These novel methods have demonstrated impressive performance in univariate and low-dimensional multivariate time-series forecasting tasks. However, when these novel methods are used to handle high-dimensional multivariate forecasting problems, their performance is highly restricted by a practical training time and a reasonable GPU memory configuration. In this paper, inspired by a change of basis in the Hilbert space, we propose a flexible data feature extraction technique that excels in high-dimensional multivariate forecasting tasks. Our approach was originally developed for the National Science Foundation (NSF) Algorithms for Threat Detection (ATD) 2022 Challenge. Implemented using the attention mechanism and Convolutional Neural Networks (CNN) architecture, our method demonstrates great performance and compatibility. Our models trained on the GDELT Dataset finished 1st and 2nd places in the ATD sprint series and hold promise for other datasets for time series forecasting.

We present a novel camera path optimization framework for the task of online video stabilization. Typically, a stabilization pipeline consists of three steps: motion estimating, path smoothing, and novel view rendering. Most previous methods concentrate on motion estimation, proposing various global or local motion models. In contrast, path optimization receives relatively less attention, especially in the important online setting, where no future frames are available. In this work, we adopt recent off-the-shelf high-quality deep motion models for the motion estimation to recover the camera trajectory and focus on the latter two steps. Our network takes a short 2D camera path in a sliding window as input and outputs the stabilizing warp field of the last frame in the window, which warps the coming frame to its stabilized position. A hybrid loss is well-defined to constrain the spatial and temporal consistency. In addition, we build a motion dataset that contains stable and unstable motion pairs for the training. Extensive experiments demonstrate that our approach significantly outperforms state-of-the-art online methods both qualitatively and quantitatively and achieves comparable performance to offline methods.

This paper provides an introductory survey to GPT-3. We cover some of the historical development behind this technology, some of the key features of GPT-3, and discuss the machine learning model and the datasets used. We survey both academic and commercial efforts applying GPT-3 in diverse domains such as developing conversational AI chatbots, software development, creative work, domain knowledge, and business productivity. We discuss some of the challenges that GPT-3 faces such as the problems of training complexity, bias, and hallucination/incorrect answers. We also discuss the future research opportunities in this area.

Image super-resolution is a common task on mobile and IoT devices, where one often needs to upscale and enhance low-resolution images and video frames. While numerous solutions have been proposed for this problem in the past, they are usually not compatible with low-power mobile NPUs having many computational and memory constraints. In this Mobile AI challenge, we address this problem and propose the participants to design an efficient quantized image super-resolution solution that can demonstrate a real-time performance on mobile NPUs. The participants were provided with the DIV2K dataset and trained INT8 models to do a high-quality 3X image upscaling. The runtime of all models was evaluated on the Synaptics VS680 Smart Home board with a dedicated edge NPU capable of accelerating quantized neural networks. All proposed solutions are fully compatible with the above NPU, demonstrating an up to 60 FPS rate when reconstructing Full HD resolution images. A detailed description of all models developed in the challenge is provided in this paper.

Batch Normalization (BN) is an important preprocessing step to many deep learning applications. Since it is a data-dependent process, for some homogeneous datasets it is a redundant or even a performance-degrading process. In this paper, we propose an early-stage feasibility assessment method for estimating the benefits of applying BN on the given data batches. The proposed method uses a novel threshold-based approach to classify the training data batches into two sets according to their need for normalization. The need for normalization is decided based on the feature heterogeneity of the considered batch. The proposed approach is a pre-training processing, which implies no training overhead. The evaluation results show that the proposed approach achieves better performance mostly in small batch sizes than the traditional BN using MNIST, Fashion-MNIST, CIFAR-10, and CIFAR-100 datasets. Additionally, the network stability is increased by reducing the occurrence of internal variable transformation.

在本文中，我们提出了一个称为SDFE-LV的大规模，多源和不受约束的数据库，用于发现长视频中完整动态面部表达的发作和偏移帧，这被称为动态面部表情斑点的主题（DFE）和许多面部表达分析任务的重要步骤。具体而言，SDFE-LV由1,191个长视频组成，每个视频包含一个或多个完整的动态面部表情。此外，在相应的长视频中，每个完整的动态面部表达都被10次训练有素的注释者独立标记了五次。据我们所知，SDFE-LV是DFES任务的第一个无限制的大规模数据库，其长期视频是从多个现实世界/密切现实世界中的媒体来源收集的，例如电视采访，纪录片，电影和电影，以及我们媒体短视频。因此，在实践中，SDFE-LV数据库上的DFE任务将遇到许多困难，例如头部姿势变化，遮挡和照明。我们还通过使用许多最新的深度发现方法，从不同角度提供了全面的基准评估，因此对DFE感兴趣的研究人员可以快速而轻松地开始。最后，通过有关实验评估结果的深入讨论，我们试图指出几个有意义的方向来处理DFES任务，并希望将来DFE可以更好地进步。此外，SDFE-LV将仅尽快自由发布供学术使用。

经过标准的横向损失训练的深度神经网络更容易记住嘈杂的标签，从而降低了其性能。当嘈杂的标签干预时，使用互补标签的负面学习更加健壮，但模型收敛速度极慢。在本文中，我们首先引入了双向学习方案，在这种方案中，积极的学习可确保收敛速度，而负面学习则可以与标签噪声保持稳健的应对。此外，提出了一种动态样本重新加权策略，以通过利用负面学习对样本概率分布的出色歧视能力来削弱噪声标记样品的影响。此外，我们结合了自我鉴定，以进一步提高模型性能。该代码可在\ url {https://github.com/chenchenzong/bldr}中获得。

COVID-19大流行刺激的快速数字化导致了更多的网络犯罪。现在，恶意软件即服务是网络犯罪分子的蓬勃发展的业务。随着恶意软件活动的激增，对于网络辩护人来说，更多地了解他们手头的恶意软件样本，因为这些信息可以极大地影响他们在违规过程中的下一步行动。最近，研究人员展示了如何通过将恶意软件二进制文件转换为灰度图像，然后通过神经网络进行分类来完成恶意软件家庭分类。但是，大多数工作着重于研究不同神经网络体系结构对分类性能的影响。在去年，研究人员表明，通过自我监督学习来增强监督学习可以提高绩效。甚至最近，Data2Vec被提议为一种训练神经网络的情态自我监督框架。在本文中，我们介绍了Binimg2Vec，这是一个培训恶意软件二进制图像分类器的框架，该框架既包含了自我监督的学习和监督学习，又可以产生一个模型，该模型始终优于仅通过监督学习而受过培训的模型。我们能够在分类性能上提高4％，并在多次运行中降低0.5％的性能差异。我们还展示了我们的框架如何产生可以很好地聚类的嵌入，从而促进模型的解释。
