Cartoonization is a task that renders natural photos into cartoon styles. Previous deep cartoonization methods only have focused on end-to-end translation, which may hinder editability. Instead, we propose a novel solution with editing features of texture and color based on the cartoon creation process. To do that, we design a model architecture to have separate decoders, texture and color, to decouple these attributes. In the texture decoder, we propose a texture controller, which enables a user to control stroke style and abstraction to generate diverse cartoon textures. We also introduce an HSV color augmentation to induce the networks to generate diverse and controllable color translation. To the best of our knowledge, our work is the first deep approach to control the cartoonization at inference while showing profound quality improvement over to baselines.

We approach the problem of improving robustness of deep learning algorithms in the presence of label noise. Building upon existing label correction and co-teaching methods, we propose a novel training procedure to mitigate the memorization of noisy labels, called CrossSplit, which uses a pair of neural networks trained on two disjoint parts of the dataset. CrossSplit combines two main ingredients: (i) Cross-split label correction. The idea is that, since the model trained on one part of the data cannot memorize example-label pairs from the other part, the training labels presented to each network can be smoothly adjusted by using the predictions of its peer network; (ii) Cross-split semi-supervised training. A network trained on one part of the data also uses the unlabeled inputs of the other part. Extensive experiments on CIFAR-10, CIFAR-100, Tiny-ImageNet and mini-WebVision datasets demonstrate that our method can outperform the current state-of-the-art up to 90% noise ratio.

现有的图像到图像翻译技术通常遭受了两个关键问题：严重依赖按样本域注释和/或无法处理每个图像的多个属性。最近的方法采用聚类方法来轻松以无监督的方式提供样本注释。但是，他们无法解释现实环境。一个样本可能具有多个属性。此外，集群的语义不容易与人类的理解相结合。为了克服这些，我们提出了一种语言驱动的图像到图像翻译模型，称为LANIT。我们利用文本中给出的易于访问的候选域注释，并在培训期间共同优化它们。目标样式是通过根据多热域分配汇总多域样式向量来指定的。由于最初的候选域文本可能不准确，因此我们将候选域文本设置为可学习的，并在培训期间共同对其进行微调。此外，我们引入了一个松弛域，以涵盖候选域未覆盖的样品。对几个标准基准测试的实验表明，LANIT与现有模型具有可比性或优越的性能。

机器学习模型的解释性一直是机器学习系统安全部署的重要领域。一种特殊的方法是将模型决策归因于人类可以理解的高级概念。但是，这种基于概念的深度神经网络（DNN）的解释性主要在图像域上进行了研究。在本文中，我们通过提供有关如何在表格数据上定义概念的想法，将概念归因方法（概念归因方法）扩展到表格学习。在具有基本概念解释和现实世界数据集的合成数据集中，我们显示了方法在生成与人类水平直觉相匹配的可解释性结果方面的有效性。最重要的是，我们提出了一个基于TCAV的公平性概念，该概念量化了哪个DNN层学习的表示形式，从而导致对模型的偏见。另外，我们从经验上证明了基于TCAV的公平性与群体公平概念，人口统计学的关系。

超声检查的诊断准确性提高仍然是一个重要目标。在这项研究中，我们提出了一种基于生物物理特征的机器学习方法，用于乳腺癌检测，以改善基准深度学习算法以外的性能，并提供一张颜色的覆盖层覆盖层的视觉图，这些视觉图是病变中恶性肿瘤的可能性。该总体框架称为特定疾病的成像。以前，分别利用改良的完全卷积网络和改良的Googlenet对150个乳房病变进行了细分和分类。在这项研究中，在轮廓病变中进行了多参数分析。从基于生物物理和形态学模型的超声射频，包膜和对数压缩数据中提取特征。带有高斯内核的支持向量机构建了非线性超平面，我们计算了多参数空间中每个特征的超平面和数据点之间的距离。距离可以定量评估病变，并提出颜色编码并覆盖在B模式图像上的恶性肿瘤的可能性。对体内患者数据进行了培训和评估。在我们的研究中，最常见类型和大小的乳腺病变的总体准确性超过98.0％，分类为0.98，而接收器操作特征曲线下的区域的总体准确性比放射科医生的性能和深度学习系统更精确。此外，概率与BI RAD之间的相关性实现了预测乳腺癌的定量指南。因此，我们预计所提出的框架可以帮助放射科医生实现更准确，方便的乳腺癌分类和检测。

降低降低和聚类通常被用作许多复杂机器学习任务的初步步骤。噪声和离群值的存在可能会恶化此类预处理的性能，从而极大地损害了后续分析。在流形学习中，几项研究表明，当密度大大高于噪声所示时，可以消除接近结构的背景噪声或接近结构的解决方案。但是，在包括天文数据集在内的许多应用中，密度随埋在嘈杂背景的流形而变化。我们提出了一种基于蚂蚁菌落优化的思想，在存在噪声的情况下提取歧管的新方法。与现有的随机步行解决方案相反，我们的技术捕获了与歧管的主要方向局部对齐的点。此外，我们从经验上表明，蚂蚁信息素的生物学启发的配方增强了这种行为，使其能够恢复嵌入极其嘈杂的数据云中的多个歧管。与在几个合成和真实数据集上（包括宇宙学量的N体模拟）相比，证明了与最新的降噪方法的最新方法相比，算法性能。

The 3D-aware image synthesis focuses on conserving spatial consistency besides generating high-resolution images with fine details. Recently, Neural Radiance Field (NeRF) has been introduced for synthesizing novel views with low computational cost and superior performance. While several works investigate a generative NeRF and show remarkable achievement, they cannot handle conditional and continuous feature manipulation in the generation procedure. In this work, we introduce a novel model, called Class-Continuous Conditional Generative NeRF ($\text{C}^{3}$G-NeRF), which can synthesize conditionally manipulated photorealistic 3D-consistent images by projecting conditional features to the generator and the discriminator. The proposed $\text{C}^{3}$G-NeRF is evaluated with three image datasets, AFHQ, CelebA, and Cars. As a result, our model shows strong 3D-consistency with fine details and smooth interpolation in conditional feature manipulation. For instance, $\text{C}^{3}$G-NeRF exhibits a Fr\'echet Inception Distance (FID) of 7.64 in 3D-aware face image synthesis with a $\text{128}^{2}$ resolution. Additionally, we provide FIDs of generated 3D-aware images of each class of the datasets as it is possible to synthesize class-conditional images with $\text{C}^{3}$G-NeRF.

In both terrestrial and marine ecology, physical tagging is a frequently used method to study population dynamics and behavior. However, such tagging techniques are increasingly being replaced by individual re-identification using image analysis. This paper introduces a contrastive learning-based model for identifying individuals. The model uses the first parts of the Inception v3 network, supported by a projection head, and we use contrastive learning to find similar or dissimilar image pairs from a collection of uniform photographs. We apply this technique for corkwing wrasse, Symphodus melops, an ecologically and commercially important fish species. Photos are taken during repeated catches of the same individuals from a wild population, where the intervals between individual sightings might range from a few days to several years. Our model achieves a one-shot accuracy of 0.35, a 5-shot accuracy of 0.56, and a 100-shot accuracy of 0.88, on our dataset.

Feature selection helps reduce data acquisition costs in ML, but the standard approach is to train models with static feature subsets. Here, we consider the dynamic feature selection (DFS) problem where a model sequentially queries features based on the presently available information. DFS is often addressed with reinforcement learning (RL), but we explore a simpler approach of greedily selecting features based on their conditional mutual information. This method is theoretically appealing but requires oracle access to the data distribution, so we develop a learning approach based on amortized optimization. The proposed method is shown to recover the greedy policy when trained to optimality and outperforms numerous existing feature selection methods in our experiments, thus validating it as a simple but powerful approach for this problem.

The purpose of this work was to tackle practical issues which arise when using a tendon-driven robotic manipulator with a long, passive, flexible proximal section in medical applications. A separable robot which overcomes difficulties in actuation and sterilization is introduced, in which the body containing the electronics is reusable and the remainder is disposable. A control input which resolves the redundancy in the kinematics and a physical interpretation of this redundancy are provided. The effect of a static change in the proximal section angle on bending angle error was explored under four testing conditions for a sinusoidal input. Bending angle error increased for increasing proximal section angle for all testing conditions with an average error reduction of 41.48% for retension, 4.28% for hysteresis, and 52.35% for re-tension + hysteresis compensation relative to the baseline case. Two major sources of error in tracking the bending angle were identified: time delay from hysteresis and DC offset from the proximal section angle. Examination of these error sources revealed that the simple hysteresis compensation was most effective for removing time delay and re-tension compensation for removing DC offset, which was the primary source of increasing error. The re-tension compensation was also tested for dynamic changes in the proximal section and reduced error in the final configuration of the tip by 89.14% relative to the baseline case.
