当测试图像提出看不见的分布时，深层分割模型通常会面临故障风险。改善模型鲁棒性针对这些风险的鲁棒性对于深层模型的大规模临床应用至关重要。在这项研究中，受到人类学习周期的启发，我们提出了一个新颖的在线反思学习框架（REFSEG），以改善细分鲁棒性。基于启用概念的反射概念，我们的refseg首先驱动了深层模型以采取行动以获得语义分割。然后，refseg触发模型以反映自身。因为使深层模型在测试过程中意识到他们的细分失败是具有挑战性的，所以RefSeg合成了从语义面具中综合的逼真的代理图像，以帮助深层模型构建直观有效的反射。该代理翻译并强调了分割缺陷。通过最大程度地提高原始输入和代理之间的结构相似性，可以改善分割鲁棒性的反射循环。 REFSEG在测试阶段运行，并且是分割模型的一般性。通过公共心脏MR数据集和两个内部大型超声数据集对三个医疗图像细分任务进行了广泛的验证，这表明我们的refseg显着提高了模型的鲁棒性，并报告了与强大竞争对手有关的最先进的表现。

超声（US）广泛用于实时成像，无辐射和便携性的优势。在临床实践中，分析和诊断通常依赖于美国序列，而不是单个图像来获得动态的解剖信息。对于新手来说，这是一项挑战，因为使用患者的足够视频进行练习是临床上不可行的。在本文中，我们提出了一个新颖的框架，以综合高保真美国视频。具体而言，合成视频是通过基于给定驾驶视频的动作来动画源内容图像来生成的。我们的亮点是三倍。首先，利用自我监督学习的优势，我们提出的系统以弱监督的方式进行了培训，以进行关键点检测。然后，这些关键点为处理美国视频中的复杂动态动作提供了重要信息。其次，我们使用双重解码器将内容和纹理学习解除，以有效地减少模型学习难度。最后，我们采用了对抗性训练策略，并采用了GAN损失，以进一步改善生成的视频的清晰度，从而缩小了真实和合成视频之间的差距。我们在具有高动态运动的大型内部骨盆数据集上验证我们的方法。广泛的评估指标和用户研究证明了我们提出的方法的有效性。

回归学习是经典的，是医学图像分析的基础。它为许多关键应用程序提供了连续的映射，例如属性估计，对象检测，分割和非刚性注册。但是，先前的研究主要以案例标准（如均方误差）为优化目标。他们忽略了非常重要的人口相关标准，这正是许多任务中的最终评估指标。在这项工作中，我们建议通过有关直接优化细粒相关损失的新型研究来重新审视经典回归任务。我们主要探索两个互补相关索引作为可学习的损失：Pearson线性相关（PLC）和Spearman等级相关性（SRC）。本文的贡献是两个折叠。首先，对于全球层面的PLC，我们提出了一项策略，以使其对异常值进行强大的态度并规范关键分布因素。这些努力显着稳定学习并扩大了PLC的功效。其次，对于本地级别的SRC，我们提出了一种粗到精细的方案，以减轻样品之间确切排名顺序的学习。具体而言，我们将样本排名的学习转换为样本之间相似关系的学习。我们在两个典型的超声图像回归任务上广泛验证了我们的方法，包括图像质量评估和生物措施测量。实验证明，通过直接优化相关性的细粒度指导，回归性能得到显着提高。我们提出的相关性损失是一般的，可以扩展到更重要的应用程序。

Masked image modeling (MIM) performs strongly in pre-training large vision Transformers (ViTs). However, small models that are critical for real-world applications cannot or only marginally benefit from this pre-training approach. In this paper, we explore distillation techniques to transfer the success of large MIM-based pre-trained models to smaller ones. We systematically study different options in the distillation framework, including distilling targets, losses, input, network regularization, sequential distillation, etc, revealing that: 1) Distilling token relations is more effective than CLS token- and feature-based distillation; 2) An intermediate layer of the teacher network as target perform better than that using the last layer when the depth of the student mismatches that of the teacher; 3) Weak regularization is preferred; etc. With these findings, we achieve significant fine-tuning accuracy improvements over the scratch MIM pre-training on ImageNet-1K classification, using all the ViT-Tiny, ViT-Small, and ViT-base models, with +4.2%/+2.4%/+1.4% gains, respectively. Our TinyMIM model of base size achieves 52.2 mIoU in AE20K semantic segmentation, which is +4.1 higher than the MAE baseline. Our TinyMIM model of tiny size achieves 79.6% top-1 accuracy on ImageNet-1K image classification, which sets a new record for small vision models of the same size and computation budget. This strong performance suggests an alternative way for developing small vision Transformer models, that is, by exploring better training methods rather than introducing inductive biases into architectures as in most previous works.

The recent increase in public and academic interest in preserving biodiversity has led to the growth of the field of conservation technology. This field involves designing and constructing tools that utilize technology to aid in the conservation of wildlife. In this article, we will use case studies to demonstrate the importance of designing conservation tools with human-wildlife interaction in mind and provide a framework for creating successful tools. These case studies include a range of complexities, from simple cat collars to machine learning and game theory methodologies. Our goal is to introduce and inform current and future researchers in the field of conservation technology and provide references for educating the next generation of conservation technologists. Conservation technology not only has the potential to benefit biodiversity but also has broader impacts on fields such as sustainability and environmental protection. By using innovative technologies to address conservation challenges, we can find more effective and efficient solutions to protect and preserve our planet's resources.

Different people speak with diverse personalized speaking styles. Although existing one-shot talking head methods have made significant progress in lip sync, natural facial expressions, and stable head motions, they still cannot generate diverse speaking styles in the final talking head videos. To tackle this problem, we propose a one-shot style-controllable talking face generation framework. In a nutshell, we aim to attain a speaking style from an arbitrary reference speaking video and then drive the one-shot portrait to speak with the reference speaking style and another piece of audio. Specifically, we first develop a style encoder to extract dynamic facial motion patterns of a style reference video and then encode them into a style code. Afterward, we introduce a style-controllable decoder to synthesize stylized facial animations from the speech content and style code. In order to integrate the reference speaking style into generated videos, we design a style-aware adaptive transformer, which enables the encoded style code to adjust the weights of the feed-forward layers accordingly. Thanks to the style-aware adaptation mechanism, the reference speaking style can be better embedded into synthesized videos during decoding. Extensive experiments demonstrate that our method is capable of generating talking head videos with diverse speaking styles from only one portrait image and an audio clip while achieving authentic visual effects.

Decompilation aims to transform a low-level program language (LPL) (eg., binary file) into its functionally-equivalent high-level program language (HPL) (e.g., C/C++). It is a core technology in software security, especially in vulnerability discovery and malware analysis. In recent years, with the successful application of neural machine translation (NMT) models in natural language processing (NLP), researchers have tried to build neural decompilers by borrowing the idea of NMT. They formulate the decompilation process as a translation problem between LPL and HPL, aiming to reduce the human cost required to develop decompilation tools and improve their generalizability. However, state-of-the-art learning-based decompilers do not cope well with compiler-optimized binaries. Since real-world binaries are mostly compiler-optimized, decompilers that do not consider optimized binaries have limited practical significance. In this paper, we propose a novel learning-based approach named NeurDP, that targets compiler-optimized binaries. NeurDP uses a graph neural network (GNN) model to convert LPL to an intermediate representation (IR), which bridges the gap between source code and optimized binary. We also design an Optimized Translation Unit (OTU) to split functions into smaller code fragments for better translation performance. Evaluation results on datasets containing various types of statements show that NeurDP can decompile optimized binaries with 45.21% higher accuracy than state-of-the-art neural decompilation frameworks.

Driven by improved architectures and better representation learning frameworks, the field of visual recognition has enjoyed rapid modernization and performance boost in the early 2020s. For example, modern ConvNets, represented by ConvNeXt, have demonstrated strong performance in various scenarios. While these models were originally designed for supervised learning with ImageNet labels, they can also potentially benefit from self-supervised learning techniques such as masked autoencoders (MAE). However, we found that simply combining these two approaches leads to subpar performance. In this paper, we propose a fully convolutional masked autoencoder framework and a new Global Response Normalization (GRN) layer that can be added to the ConvNeXt architecture to enhance inter-channel feature competition. This co-design of self-supervised learning techniques and architectural improvement results in a new model family called ConvNeXt V2, which significantly improves the performance of pure ConvNets on various recognition benchmarks, including ImageNet classification, COCO detection, and ADE20K segmentation. We also provide pre-trained ConvNeXt V2 models of various sizes, ranging from an efficient 3.7M-parameter Atto model with 76.7% top-1 accuracy on ImageNet, to a 650M Huge model that achieves a state-of-the-art 88.9% accuracy using only public training data.

In this paper, we propose a novel framework dubbed peer learning to deal with the problem of biased scene graph generation (SGG). This framework uses predicate sampling and consensus voting (PSCV) to encourage different peers to learn from each other, improving model diversity and mitigating bias in SGG. To address the heavily long-tailed distribution of predicate classes, we propose to use predicate sampling to divide and conquer this issue. As a result, the model is less biased and makes more balanced predicate predictions. Specifically, one peer may not be sufficiently diverse to discriminate between different levels of predicate distributions. Therefore, we sample the data distribution based on frequency of predicates into sub-distributions, selecting head, body, and tail classes to combine and feed to different peers as complementary predicate knowledge during the training process. The complementary predicate knowledge of these peers is then ensembled utilizing a consensus voting strategy, which simulates a civilized voting process in our society that emphasizes the majority opinion and diminishes the minority opinion. This approach ensures that the learned representations of each peer are optimally adapted to the various data distributions. Extensive experiments on the Visual Genome dataset demonstrate that PSCV outperforms previous methods. We have established a new state-of-the-art (SOTA) on the SGCls task by achieving a mean of \textbf{31.6}.
