Over the past few years, the field of adversarial attack received numerous attention from various researchers with the help of successful attack success rate against well-known deep neural networks that were acknowledged to achieve high classification ability in various tasks. However, majority of the experiments were completed under a single model, which we believe it may not be an ideal case in a real-life situation. In this paper, we introduce a novel federated adversarial training method for smart home face recognition, named FLATS, where we observed some interesting findings that may not be easily noticed in a traditional adversarial attack to federated learning experiments. By applying different variations to the hyperparameters, we have spotted that our method can make the global model to be robust given a starving federated environment. Our code can be found on https://github.com/jcroh0508/FLATS.

Pre-trained language models allowed us to process downstream tasks with the help of fine-tuning, which aids the model to achieve fairly high accuracy in various Natural Language Processing (NLP) tasks. Such easily-downloaded language models from various websites empowered the public users as well as some major institutions to give a momentum to their real-life application. However, it was recently proven that models become extremely vulnerable when they are backdoor attacked with trigger-inserted poisoned datasets by malicious users. The attackers then redistribute the victim models to the public to attract other users to use them, where the models tend to misclassify when certain triggers are detected within the training sample. In this paper, we will introduce a novel improved textual backdoor defense method, named MSDT, that outperforms the current existing defensive algorithms in specific datasets. The experimental results illustrate that our method can be effective and constructive in terms of defending against backdoor attack in text domain.

Image captioning is one of the straightforward tasks that can take advantage of large-scale web-crawled data which provides rich knowledge about the visual world for a captioning model. However, since web-crawled data contains image-text pairs that are aligned at different levels, the inherent noises (e.g., misaligned pairs) make it difficult to learn a precise captioning model. While the filtering strategy can effectively remove noisy data, however, it leads to a decrease in learnable knowledge and sometimes brings about a new problem of data deficiency. To take the best of both worlds, we propose a noise-aware learning framework, which learns rich knowledge from the whole web-crawled data while being less affected by the noises. This is achieved by the proposed quality controllable model, which is learned using alignment levels of the image-text pairs as an additional control signal during training. The alignment-conditioned training allows the model to generate high-quality captions of well-aligned by simply setting the control signal to desired alignment level at inference time. Through in-depth analysis, we show that our controllable captioning model is effective in handling noise. In addition, with two tasks of zero-shot captioning and text-to-image retrieval using generated captions (i.e., self-retrieval), we also demonstrate our model can produce high-quality captions in terms of descriptiveness and distinctiveness.

We tackle open-world semantic segmentation, which aims at learning to segment arbitrary visual concepts in images, by using only image-text pairs without dense annotations. Existing open-world segmentation methods have shown impressive advances by employing contrastive learning (CL) to learn diverse visual concepts and adapting the learned image-level understanding to the segmentation task. However, these methods based on CL have a discrepancy since it only considers image-text level alignment in training time, while the segmentation task requires region-text level alignment at test time. In this paper, we propose a novel Text-grounded Contrastive Learning (TCL) framework to directly align a text and a region described by the text to address the train-test discrepancy. Our method generates a segmentation mask associated with a given text, extracts grounded image embedding from the masked region, and aligns it with text embedding via TCL. The framework addresses the discrepancy by letting the model learn region-text level alignment instead of image-text level alignment and encourages the model to directly improve the quality of generated segmentation masks. In addition, for a rigorous and fair comparison, we present a unified evaluation protocol with widely used 8 semantic segmentation datasets. TCL achieves state-of-the-art zero-shot segmentation performance with large margins in all datasets. Code is available at https://github.com/kakaobrain/tcl.

随着深度学习（DL）的引入，常用心电图（ECG）诊断模型的性能改善。但是，尚未充分研究多个DL组件的各种组合和/或数据增强技术对诊断的作用的影响。这项研究提出了一种基于集合的多视图学习方法，采用ECG增强技术，比传统的12级ECG诊断方法获得更高的性能。数据分析结果表明，所提出的模型报告的F1得分为0.840，这表现优于文献中现有的最新方法。

在多视图3D对象检测任务中，重叠图像区域的差异监督显着改善了整体检测性能。但是，当前的多视图3D对象检测方法通常无法正确检测重叠区域中的对象，并且网络对场景的理解通常仅限于单眼检测网络。为了减轻此问题，我们主张应用传统的立体声差异估计方法，以获取重叠区域的可靠差异信息。鉴于差异估计为监督，我们建议将网络正规化以充分利用双眼图像的几何潜力，并提高整体检测准确性。此外，我们建议使用对抗重叠区域的歧视器，该区域的训练以最大程度地减少非重叠区域和重叠区域之间的代表性差距，在这些区域中通常会因摄像机失真而在很大程度上被遮挡或因变形而遭受变形，从而导致域移动，从而导致域移动。我们用大规模的多视图3D对象检测基准（称为Nuscenes）证明了所提出的方法的有效性。我们的实验表明，我们提出的方法的表现优于当前最新方法。

软件2.0是软件工程的根本班次，机器学习成为新软件，由大数据和计算基础设施供电。因此，需要重新考虑软件工程，其中数据成为与代码相提并论的一流公民。一个引人注目的观察是，80-90％的机器学习过程都花在数据准备上。没有良好的数据，即使是最好的机器学习算法也不能表现良好。结果，以数据为中心的AI实践现在成为主流。不幸的是，现实世界中的许多数据集是小，肮脏，偏见，甚至中毒。在本调查中，我们研究了数据收集和数据质量的研究景观，主要用于深度学习应用。数据收集很重要，因为对于最近的深度学习方法，功能工程较小，而且需要大量数据。对于数据质量，我们研究数据验证和数据清洁技术。即使数据无法完全清洁，我们仍然可以应对模型培训期间的不完美数据，其中使用鲁棒模型培训技术。此外，虽然在传统数据管理研究中较少研究偏见和公平性，但这些问题成为现代机器学习应用中的重要主题。因此，我们研究了可以在模型培训之前，期间或之后应用的公平措施和不公平的缓解技术。我们相信数据管理界很好地解决了这些方向上的问题。

最近的生成模型的成功表明，利用多模态嵌入空间可以使用文本信息操纵图像。然而，由于源的动态特性，使用其他来源而不是声音的文本来操纵图像，而不是声音，并不容易。特别是，声音可以传达真实世界的生动情感和动态表达。在这里，我们提出了一个框架，该框架将声音直接编码为多模态（图像文本）嵌入空间，并从空间操纵图像。我们的音频编码器受过培训以产生来自音频输入的潜在表示，该音频输入被强制与多模式嵌入空间中的图像和文本表示对齐。我们使用基于对齐的嵌入式的直接潜在优化方法进行声音引导图像操纵。我们还表明，我们的方法可以混合文本和音频模态，这丰富了各种图像修改。我们验证了定量和定性的声音引导图像操纵的有效性。我们还表明，我们的方法可以混合不同的模态，即文本和音频，这丰富了图像修改的各种。零射频分类和语义级图像分类的实验表明，我们所提出的模型优于其他文本和声音引导最先进的方法。

DETR是使用变压器编码器 - 解码器架构的第一端到端对象检测器，并在高分辨率特征映射上展示竞争性能但低计算效率。随后的工作变形Detr，通过更换可变形的关注来提高DEDR的效率，这实现了10倍的收敛性和改进的性能。可变形DETR使用多尺度特征来改善性能，但是，与DETR相比，编码器令牌的数量增加了20倍，编码器注意的计算成本仍然是瓶颈。在我们的初步实验中，我们观察到，即使只更新了编码器令牌的一部分，检测性能也几乎没有恶化。灵感来自该观察，我们提出了稀疏的DETR，其仅选择性更新预期的解码器预期的令牌，从而有效地检测模型。此外，我们表明在编码器中的所选令牌上应用辅助检测丢失可以提高性能，同时最小化计算开销。即使在Coco数据集上只有10％的编码器令牌，我们验证稀疏DETR也可以比可变形DETR实现更好的性能。尽管只有编码器令牌稀疏，但总计算成本减少了38％，与可变形的Detr相比，每秒帧（FPS）增加42％。代码可在https://github.com/kakaobrain/sparse-dett

对于机器人来说，了解人类指令并在不久的将来执行有意义的任务，重要的是开发学习的模型，了解了参考语言，以识别现实世界3D场景中的共同对象。在本文中，我们介绍了一种用于3D视觉接地问题的空间语言模型。具体地，给定具有潜在对象候选的3D边界框的点云形式的重建的3D场景，以及参考场景中的目标对象的语言话语，我们的模型成功地将目标对象从一组潜在的候选者识别。具体而言，Languagrefer使用基于变压器的架构，该架构将空间嵌入与边界框中的空间嵌入与来自Distilbert的微调语言嵌入式的绑定框相结合，以预测目标对象。我们表明它竞争地表现在引用3D提出的Visio-linguistic数据集上。此外，我们分析其空间推理任务性能与感知噪声分离，视图依赖性话语的准确性，以及用于潜在机器人应用的观点注释。
