Pareto Front Learning (PFL) was recently introduced as an effective approach to obtain a mapping function from a given trade-off vector to a solution on the Pareto front, which solves the multi-objective optimization (MOO) problem. Due to the inherent trade-off between conflicting objectives, PFL offers a flexible approach in many scenarios in which the decision makers can not specify the preference of one Pareto solution over another, and must switch between them depending on the situation. However, existing PFL methods ignore the relationship between the solutions during the optimization process, which hinders the quality of the obtained front. To overcome this issue, we propose a novel PFL framework namely \ourmodel, which employs a hypernetwork to generate multiple solutions from a set of diverse trade-off preferences and enhance the quality of the Pareto front by maximizing the Hypervolume indicator defined by these solutions. The experimental results on several MOO machine learning tasks show that the proposed framework significantly outperforms the baselines in producing the trade-off Pareto front.

在本文中，我们采用了最大化的互信息（MI）方法来解决无监督的二进制哈希代码的问题，以实现高效的跨模型检索。我们提出了一种新颖的方法，被称为跨模型信息最大散列（CMIMH）。首先，要学习可以保留模跨和跨间相似性的信息的信息，我们利用最近估计MI的变分的进步，以最大化二进制表示和输入特征之间的MI以及不同方式的二进制表示之间的MI。通过在假设由多变量Bernoulli分布模型的假设下联合最大化这些MIM，我们可以学习二进制表示，该二进制表示，其可以在梯度下降中有效地以微量批量方式有效地保留帧内和模态的相似性。此外，我们发现尝试通过学习与来自不同模式的相同实例的类似二进制表示来最小化模态差距，这可能导致更少的信息性表示。因此，在减少模态间隙和失去模态 - 私人信息之间平衡对跨模型检索任务很重要。标准基准数据集上的定量评估表明，该方法始终如一地优于其他最先进的跨模型检索方法。

人脸识别是模式识别区域中非常重要的领域。它在军事和金融中有多种申请，名称为几个。在本文中，将提出与最近邻的方法的稀疏PCA的组合（以及与内核脊回归方法），并将应用于解决面部识别问题。实验结果表明，稀疏PCA方法的组合（使用近端梯度法和FISTA方法）和一个特定分类系统的准确性可能低于PCA方法和一个特定分类系统的组合的精度，但有时稀疏PCA方法的组合（使用近端梯度法或Fista方法）和一个特定的分类系统导致更好的准确性。此外，我们认识到，使用Fista方法计算稀疏PCA算法的过程总比使用近端梯度方法计算稀疏PCA算法的过程。

本文介绍了伯特嵌入法和图形卷积神经网络的新方法。采用这种组合来解决文本分类问题。最初，我们将BERT嵌入方法应用于文本（在BBC新闻数据集和IMDB电影评论数据集）中，以便将所有文本转换为数字向量。然后，图形卷积神经网络将应用于这些数字向量，以将这些文本分类为其AP的兴趣类/标签。实验表明，图形卷积神经网络模型的性能优于具有CLAS-SICE机器学习模型的BERT嵌入方法的组合的性能。

随着人类生活中的许多实际应用，包括制造监控摄像机，分析和加工客户行为，许多研究人员都注明了对数字图像的面部检测和头部姿势估计。大量提出的深度学习模型具有最先进的准确性，如YOLO，SSD，MTCNN，解决了面部检测或HOPENET的问题，FSA-NET，用于头部姿势估计问题的速度。根据许多最先进的方法，该任务的管道由两部分组成，从面部检测到头部姿势估计。这两个步骤完全独立，不共享信息。这使得模型在设置中清除但不利用每个模型中提取的大部分特色资源。在本文中，我们提出了多任务净模型，具有利用从面部检测模型提取的特征的动机，将它们与头部姿势估计分支共享以提高精度。此外，随着各种数据，表示面部的欧拉角域大，我们的模型可以预测360欧拉角域的结果。应用多任务学习方法，多任务净模型可以同时预测人头的位置和方向。为了提高预测模型的头部方向的能力，我们将人脸从欧拉角呈现到旋转矩阵的载体。

头部姿势估计是一个具有挑战性的任务，旨在解决与预测三维向量相关的问题，这为人机互动或客户行为中的许多应用程序提供服务。以前的研究提出了一些用于收集头部姿势数据的精确方法。但这些方法需要昂贵的设备，如深度摄像机或复杂的实验室环境设置。在这项研究中，我们引入了一种新的方法，以有效的成本和易于设置，以收集头部姿势图像，即UET-HEADBETS数据集，具有顶视图头姿势数据。该方法使用绝对方向传感器而不是深度摄像机快速设置，但仍然可以确保良好的效果。通过实验，我们的数据集已显示其分发和可用数据集之间的差异，如CMU Panoptic DataSet \ Cite {CMU}。除了使用UET符号数据集和其他头部姿势数据集外，我们还介绍了称为FSANET的全范围模型，这显着优于UET-HEALPETS数据集的头部姿势估计结果，尤其是在顶视图上。此外，该模型非常重量轻，占用小尺寸图像。

In this work, we propose a new approach that combines data from multiple sensors for reliable obstacle avoidance. The sensors include two depth cameras and a LiDAR arranged so that they can capture the whole 3D area in front of the robot and a 2D slide around it. To fuse the data from these sensors, we first use an external camera as a reference to combine data from two depth cameras. A projection technique is then introduced to convert the 3D point cloud data of the cameras to its 2D correspondence. An obstacle avoidance algorithm is then developed based on the dynamic window approach. A number of experiments have been conducted to evaluate our proposed approach. The results show that the robot can effectively avoid static and dynamic obstacles of different shapes and sizes in different environments.

We introduce an approach for the answer-aware question generation problem. Instead of only relying on the capability of strong pre-trained language models, we observe that the information of answers and questions can be found in some relevant sentences in the context. Based on that, we design a model which includes two modules: a selector and a generator. The selector forces the model to more focus on relevant sentences regarding an answer to provide implicit local information. The generator generates questions by implicitly combining local information from the selector and global information from the whole context encoded by the encoder. The model is trained jointly to take advantage of latent interactions between the two modules. Experimental results on two benchmark datasets show that our model is better than strong pre-trained models for the question generation task. The code is also available (shorturl.at/lV567).

Despite their widespread adoption, neural conversation models have yet to exhibit natural chat capabilities with humans. In this research, we examine user utterances as causes and generated responses as effects, recognizing that changes in a cause should produce a different effect. To further explore this concept, we have compiled and expanded upon a new dataset called CausalDialogue through crowd-sourcing. This dataset includes multiple cause-effect pairs within a directed acyclic graph (DAG) structure. Our analysis reveals that traditional loss functions can struggle to effectively incorporate the DAG structure, leading us to propose a causality-enhanced method called Exponential Maximum Average Treatment Effect (ExMATE) to enhance the impact of causality at the utterance level in training neural conversation models. To evaluate the effectiveness of this approach, we have built a comprehensive benchmark using the CausalDialogue dataset leveraging large-scale pre-trained language models, and have assessed the results through both human and automatic evaluation metrics for coherence, diversity, and agility. Our findings show that current techniques are still unable to effectively address conversational DAGs, and that the ExMATE method can improve the diversity and agility of conventional loss functions while maintaining coherence.

Machine Learning as a service (MLaaS) permits resource-limited clients to access powerful data analytics services ubiquitously. Despite its merits, MLaaS poses significant concerns regarding the integrity of delegated computation and the privacy of the server's model parameters. To address this issue, Zhang et al. (CCS'20) initiated the study of zero-knowledge Machine Learning (zkML). Few zkML schemes have been proposed afterward; however, they focus on sole ML classification algorithms that may not offer satisfactory accuracy or require large-scale training data and model parameters, which may not be desirable for some applications. We propose ezDPS, a new efficient and zero-knowledge ML inference scheme. Unlike prior works, ezDPS is a zkML pipeline in which the data is processed in multiple stages for high accuracy. Each stage of ezDPS is harnessed with an established ML algorithm that is shown to be effective in various applications, including Discrete Wavelet Transformation, Principal Components Analysis, and Support Vector Machine. We design new gadgets to prove ML operations effectively. We fully implemented ezDPS and assessed its performance on real datasets. Experimental results showed that ezDPS achieves one-to-three orders of magnitude more efficient than the generic circuit-based approach in all metrics while maintaining more desirable accuracy than single ML classification approaches.
