In robotics and computer vision communities, extensive studies have been widely conducted regarding surveillance tasks, including human detection, tracking, and motion recognition with a camera. Additionally, deep learning algorithms are widely utilized in the aforementioned tasks as in other computer vision tasks. Existing public datasets are insufficient to develop learning-based methods that handle various surveillance for outdoor and extreme situations such as harsh weather and low illuminance conditions. Therefore, we introduce a new large-scale outdoor surveillance dataset named eXtremely large-scale Multi-modAl Sensor dataset (X-MAS) containing more than 500,000 image pairs and the first-person view data annotated by well-trained annotators. Moreover, a single pair contains multi-modal data (e.g. an IR image, an RGB image, a thermal image, a depth image, and a LiDAR scan). This is the first large-scale first-person view outdoor multi-modal dataset focusing on surveillance tasks to the best of our knowledge. We present an overview of the proposed dataset with statistics and present methods of exploiting our dataset with deep learning-based algorithms. The latest information on the dataset and our study are available at https://github.com/lge-robot-navi, and the dataset will be available for download through a server.

In this study, we propose a lung nodule detection scheme which fully incorporates the clinic workflow of radiologists. Particularly, we exploit Bi-Directional Maximum intensity projection (MIP) images of various thicknesses (i.e., 3, 5 and 10mm) along with a 3D patch of CT scan, consisting of 10 adjacent slices to feed into self-distillation-based Multi-Encoders Network (MEDS-Net). The proposed architecture first condenses 3D patch input to three channels by using a dense block which consists of dense units which effectively examine the nodule presence from 2D axial slices. This condensed information, along with the forward and backward MIP images, is fed to three different encoders to learn the most meaningful representation, which is forwarded into the decoded block at various levels. At the decoder block, we employ a self-distillation mechanism by connecting the distillation block, which contains five lung nodule detectors. It helps to expedite the convergence and improves the learning ability of the proposed architecture. Finally, the proposed scheme reduces the false positives by complementing the main detector with auxiliary detectors. The proposed scheme has been rigorously evaluated on 888 scans of LUNA16 dataset and obtained a CPM score of 93.6\%. The results demonstrate that incorporating of bi-direction MIP images enables MEDS-Net to effectively distinguish nodules from surroundings which help to achieve the sensitivity of 91.5% and 92.8% with false positives rate of 0.25 and 0.5 per scan, respectively.

最近的深度学习模型在言语增强方面已经达到了高性能。但是，获得快速和低复杂模型而没有明显的性能降解仍然是一项挑战。以前的知识蒸馏研究对言语增强无法解决这个问题，因为它们的输出蒸馏方法在某些方面不符合语音增强任务。在这项研究中，我们提出了基于特征的蒸馏多视图注意转移（MV-AT），以在时域中获得有效的语音增强模型。基于多视图功能提取模型，MV-AT将教师网络的多视图知识传输到学生网络，而无需其他参数。实验结果表明，所提出的方法始终提高瓦伦蒂尼和深噪声抑制（DNS）数据集的各种规模的学生模型的性能。与基线模型相比，使用我们提出的方法（一种用于有效部署的轻巧模型）分别使用了15.4倍和4.71倍（FLOPS），与具有相似性能的基线模型相比，Many-S-8.1GF分别达到了15.4倍和4.71倍。

整个幻灯片图像（WSI）分类是诊断和治疗疾病的基本任务；但是，精确标签的策划是耗时的，并限制了完全监督的方法的应用。为了解决这个问题，多个实例学习（MIL）是一种流行的方法，它仅使用幻灯片级标签作为一个弱监督的学习任务。尽管当前的MIL方法将注意机制的变体应用于具有更强模型的重量实例特征，但注意力不足是对数据分布的属性的不足。在这项工作中，我们建议通过使用Max-Instance（关键）功能的统计数据来重新校准WSI袋（实例）的分布。我们假设在二进制MIL中，正面袋的特征幅度大于负面，因此我们可以强制执行该模型，以最大程度地利用公制特征损失的袋子之间的差异，该袋子将正面袋模型为未分布。为了实现这一目标，与使用单批训练模式的现有MIL方法不同，我们建议平衡批次采样以有效地使用功能丢失，即同时（+/-）袋子。此外，我们采用编码模块（PEM）的位置来建模空间/形态信息，并通过变压器编码器通过多头自我注意（PSMA）进行汇总。现有基准数据集的实验结果表明我们的方法是有效的，并且对最先进的MIL方法有所改善。

大多数最新的说话者验证架构都采用了多尺度处理和频道注意机制。这些模型的卷积层通常具有固定的内核大小，例如3或5。在本研究中，我们进一步为这一研究采用了选择性核心注意（SKA）机制。SKA机制允许每个卷积层以数据驱动的方式自适应地选择内核大小。它基于利用频率和通道域的注意机制。我们首先将现有的SKA模块应用于我们的基线。然后，我们提出了两个SKA变体，其中第一个变体在ECAPA-TDNN模型的前面应用，另一个变体与RES2NET骨干块结合使用。通过广泛的实验，我们证明了我们提出的两个SKA变体始终提高性能，并在三个不同的评估方案上进行测试时是互补的。

在本文中，我们提出了自我监督的发言者表示学习策略，该策略包括在前端的引导平衡扬声器表示学习和在后端的不确定性意识的概率扬声器嵌入训练。在前端阶段，我们通过具有均匀性正则化术语的引导训练方案来学习扬声器表示。在后端阶段，通过最大化属于同一扬声器的语音样本之间的相互似然分数来估计概率扬声器嵌入，这不仅提供扬声器表示，而且提供数据不确定性。实验结果表明，拟议的举止均衡训练策略可以有效地帮助了解扬声器表示，并以基于对比学习的传统方法优越。此外，我们展示了集成的两级框架在eer和mindcf方面进一步改善了VoxceleB1测试中的扬声器验证性能。

GPT-3显示了培训的大规模语言模型（LMS）的卓越情调学习能力，培训数十亿规模数据。在这里，我们解决了GPT-3纸张报告的一些剩余问题，例如非英语LM，不同大小模型的性能，以及最近引入的迅速优化对上下文学习的效果。为实现这一目标，我们介绍了HyperClova，一个韩国VPT-3的韩国变体训练在一个以韩国为中心的560b标准的令牌。通过我们的韩国特定标记化，HyperClova与我们的培训配置增强，显示了韩国各种下游任务的最先进的上下游零射击和几秒钟学习表演。此外，我们展示了基于及时的学习的性能优势，并演示如何集成到迅速的工程管道中。然后，我们讨论了通过引入Hyperclova Studio，互动提示工程界面向ML的非专家提供AI原型设计能力来实现No Code AI范例的可能性。最后，我们展示了我们具有三个成功的内部应用程序的方法的潜力。

Springs are efficient in storing and returning elastic potential energy but are unable to hold the energy they store in the absence of an external load. Lockable springs use clutches to hold elastic potential energy in the absence of an external load but have not yet been widely adopted in applications, partly because clutches introduce design complexity, reduce energy efficiency, and typically do not afford high-fidelity control over the energy stored by the spring. Here, we present the design of a novel lockable compression spring that uses a small capstan clutch to passively lock a mechanical spring. The capstan clutch can lock up to 1000 N force at any arbitrary deflection, unlock the spring in less than 10 ms with a control force less than 1 % of the maximal spring force, and provide an 80 % energy storage and return efficiency (comparable to a highly efficient electric motor operated at constant nominal speed). By retaining the form factor of a regular spring while providing high-fidelity locking capability even under large spring forces, the proposed design could facilitate the development of energy-efficient spring-based actuators and robots.

This paper proposes a new regularization algorithm referred to as macro-block dropout. The overfitting issue has been a difficult problem in training large neural network models. The dropout technique has proven to be simple yet very effective for regularization by preventing complex co-adaptations during training. In our work, we define a macro-block that contains a large number of units from the input to a Recurrent Neural Network (RNN). Rather than applying dropout to each unit, we apply random dropout to each macro-block. This algorithm has the effect of applying different drop out rates for each layer even if we keep a constant average dropout rate, which has better regularization effects. In our experiments using Recurrent Neural Network-Transducer (RNN-T), this algorithm shows relatively 4.30 % and 6.13 % Word Error Rates (WERs) improvement over the conventional dropout on LibriSpeech test-clean and test-other. With an Attention-based Encoder-Decoder (AED) model, this algorithm shows relatively 4.36 % and 5.85 % WERs improvement over the conventional dropout on the same test sets.

Diffusion-based generative models have achieved remarkable success in image generation. Their guidance formulation allows an external model to plug-and-play control the generation process for various tasks without fine-tuning the diffusion model. However, the direct use of publicly available off-the-shelf models for guidance fails due to their poor performance on noisy inputs. For that, the existing practice is to fine-tune the guidance models with labeled data corrupted with noises. In this paper, we argue that this practice has limitations in two aspects: (1) performing on inputs with extremely various noises is too hard for a single model; (2) collecting labeled datasets hinders scaling up for various tasks. To tackle the limitations, we propose a novel strategy that leverages multiple experts where each expert is specialized in a particular noise range and guides the reverse process at its corresponding timesteps. However, as it is infeasible to manage multiple networks and utilize labeled data, we present a practical guidance framework termed Practical Plug-And-Play (PPAP), which leverages parameter-efficient fine-tuning and data-free knowledge transfer. We exhaustively conduct ImageNet class conditional generation experiments to show that our method can successfully guide diffusion with small trainable parameters and no labeled data. Finally, we show that image classifiers, depth estimators, and semantic segmentation models can guide publicly available GLIDE through our framework in a plug-and-play manner.
