增量学习是一种范式，可以通过流数据大规模构建模型构建和更新。对于端到端的自动语音识别（ASR）任务，缺乏人类注释的标签，以及需要保留模型建设政策的隐私政策，这使其成为艰巨的挑战。受这些挑战的激励，在本文中，我们使用基于云的框架为生产系统展示了从隐私保存自动语音识别（ILASR）的增量学习中的见解。我们的意思是，通过保留隐私性，对没有人类注释的短暂数据使用。该系统是用于增量/持续学习的生产LevelAsASR模型的一步，该模型提供了接近实时测试床，以在云中进行端到端ASR实验，同时遵守保留隐私的政策。我们表明，即使在没有人类注释的标签的情况下，拟议的系统也可以在六个月的新时间内显着改善生产模型（3％），而在增量学习中，较弱的监督和大批量大小。在新时期，这种改进比测试集的新单词和短语相比为20％。我们在ASR的同时进一步探讨了拥有有效的教师模型和使用大批量大小的实用性的同时，以保护隐私的增量方式展示了模型构建的有效性。

在联合学习（FL）中，通过跨设备的模型更新进行合作学习全球模型的目的倾向于通过本地信息反对个性化的目标。在这项工作中，我们通过基于多准则优化的框架以定量的方式校准了这一权衡，我们将其作为一个受约束的程序进行了：设备的目标是其本地目标，它试图最大程度地减少在满足非线性约束的同时，以使其满足非线性约束，这些目标是其本地目标。量化本地模型和全局模型之间的接近度。通过考虑该问题的拉格朗日放松，我们开发了一种算法，该算法允许每个节点通过查询到一阶梯度Oracle将其Lagrangian的本地组件最小化。然后，服务器执行Lagrange乘法器上升步骤，然后进行Lagrange乘法器加权步骤。我们称这种实例化的原始偶对方法是联合学习超出共识（$ \ texttt {fedBc} $）的实例。从理论上讲，我们确定$ \ texttt {fedBc} $以与最算好状态相匹配的速率收敛到一阶固定点，直到额外的错误项，取决于由于接近性约束而产生的公差参数。总体而言，该分析是针对非凸鞍点问题的原始偶对偶的方法的新颖表征。最后，我们证明了$ \ texttt {fedBc} $平衡了整个数据集（合成，MNIST，CIFAR-10，莎士比亚）的全球和本地模型测试精度指标，从而与艺术现状达到了竞争性能。

具有周期性模型的本地随机梯度下降（SGD）平均（FEDAVG）是联合学习中的基础算法。该算法在多个工人上独立运行SGD，并定期平均所有工人的模型。然而，当本地SGD与许多工人一起运行时，周期性平均导致跨越工人的重大模型差异，使全局损失缓慢收敛。虽然最近的高级优化方法解决了专注于非IID设置的问题，但由于底层定期模型平均而仍存在模型差异问题。我们提出了一个部分模型平均框架，这些框架减轻了联合学习中的模型差异问题。部分平均鼓励本地模型在参数空间上保持彼此接近，并且它可以更有效地最小化全局损失。鉴于固定数量的迭代和大量工人（128），验证精度高达2.2％的验证精度高于周期性的完整平均值。

Federated learning involves training statistical models over remote devices or siloed data centers, such as mobile phones or hospitals, while keeping data localized. Training in heterogeneous and potentially massive networks introduces novel challenges that require a fundamental departure from standard approaches for large-scale machine learning, distributed optimization, and privacy-preserving data analysis. In this article, we discuss the unique characteristics and challenges of federated learning, provide a broad overview of current approaches, and outline several directions of future work that are relevant to a wide range of research communities.

Federated Learning is a distributed learning paradigm with two key challenges that differentiate it from traditional distributed optimization: (1) significant variability in terms of the systems characteristics on each device in the network (systems heterogeneity), and (2) non-identically distributed data across the network (statistical heterogeneity). In this work, we introduce a framework, FedProx, to tackle heterogeneity in federated networks. FedProx can be viewed as a generalization and re-parametrization of FedAvg, the current state-of-the-art method for federated learning. While this re-parameterization makes only minor modifications to the method itself, these modifications have important ramifications both in theory and in practice. Theoretically, we provide convergence guarantees for our framework when learning over data from non-identical distributions (statistical heterogeneity), and while adhering to device-level systems constraints by allowing each participating device to perform a variable amount of work (systems heterogeneity). Practically, we demonstrate that FedProx allows for more robust convergence than FedAvg across a suite of realistic federated datasets. In particular, in highly heterogeneous settings, FedProx demonstrates significantly more stable and accurate convergence behavior relative to FedAvg-improving absolute test accuracy by 22% on average.

最紧迫的社会问题之一是与虚假新闻的斗争。虚假的主张很难暴露，造成了很多损害。为了解决这个问题，事实验证变得至关重要，因此是不同研究社区中感兴趣的话题。仅使用数据的文本形式，我们建议解决问题的解决方案，并通过其他方法实现竞争结果。我们基于两种方法（基于训练的语言模型）基于两种方法和基于提示的方法提供解决方案。基于PLM的方法使用传统的监督学习，其中训练模型以“ X”为输入和输出预测为P（Y | X）。鉴于，基于及时的学习反映了设计输入以适合模型的想法，以便可以将原始目标重新构成（掩盖）语言建模的问题。我们可能会进一步刺激PLM提供的丰富知识，以通过采用额外提示来微调PLM，以更好地完成下游任务。我们的实验表明，所提出的方法的性能不仅仅是微调PLM。我们在Trancify数据集中获得了0.6946的F1分数，在比赛负责人板上获得了第七名。

虽然生成的对抗网络（GaN）是他们对其更高的样本质量的流行，而与其他生成模型相反，但是它们遭受同样困难的产生样本的难度。必须牢记各个方面，如产生的样本的质量，课程的多样性（在课堂内和类别中），使用解除戒开的潜在空间，所述评估度量的协议与人类感知等。本文，我们提出了一个新的评分，即GM分数，这取得了各种因素，如样品质量，解除戒备的代表，阶级，级别的阶级和级别多样性等各种因素，以及诸如精确，召回和F1分数等其他指标用于可怜的性深度信仰网络（DBN）和限制Boltzmann机（RBM）的潜在空间。评估是针对不同的GANS（GAN，DCGAN，BIGAN，CGAN，CONFORDGON，LSGAN，SGAN，WAN，以及WGAN改进）的不同GANS（GAN，DCGAN，BIGAN，SCAN，WANT）在基准MNIST数据集上培训。

Quadruped robots are currently used in industrial robotics as mechanical aid to automate several routine tasks. However, presently, the usage of such a robot in a domestic setting is still very much a part of the research. This paper discusses the understanding and virtual simulation of such a robot capable of detecting and understanding human emotions, generating its gait, and responding via sounds and expression on a screen. To this end, we use a combination of reinforcement learning and software engineering concepts to simulate a quadruped robot that can understand emotions, navigate through various terrains and detect sound sources, and respond to emotions using audio-visual feedback. This paper aims to establish the framework of simulating a quadruped robot that is emotionally intelligent and can primarily respond to audio-visual stimuli using motor or audio response. The emotion detection from the speech was not as performant as ERANNs or Zeta Policy learning, still managing an accuracy of 63.5%. The video emotion detection system produced results that are almost at par with the state of the art, with an accuracy of 99.66%. Due to its "on-policy" learning process, the PPO algorithm was extremely rapid to learn, allowing the simulated dog to demonstrate a remarkably seamless gait across the different cadences and variations. This enabled the quadruped robot to respond to generated stimuli, allowing us to conclude that it functions as predicted and satisfies the aim of this work.

Searching long egocentric videos with natural language queries (NLQ) has compelling applications in augmented reality and robotics, where a fluid index into everything that a person (agent) has seen before could augment human memory and surface relevant information on demand. However, the structured nature of the learning problem (free-form text query inputs, localized video temporal window outputs) and its needle-in-a-haystack nature makes it both technically challenging and expensive to supervise. We introduce Narrations-as-Queries (NaQ), a data augmentation strategy that transforms standard video-text narrations into training data for a video query localization model. Validating our idea on the Ego4D benchmark, we find it has tremendous impact in practice. NaQ improves multiple top models by substantial margins (even doubling their accuracy), and yields the very best results to date on the Ego4D NLQ challenge, soundly outperforming all challenge winners in the CVPR and ECCV 2022 competitions and topping the current public leaderboard. Beyond achieving the state-of-the-art for NLQ, we also demonstrate unique properties of our approach such as gains on long-tail object queries, and the ability to perform zero-shot and few-shot NLQ.

Machine Translation (MT) system generally aims at automatic representation of source language into target language retaining the originality of context using various Natural Language Processing (NLP) techniques. Among various NLP methods, Statistical Machine Translation(SMT). SMT uses probabilistic and statistical techniques to analyze information and conversion. This paper canvasses about the development of bilingual SMT models for translating English to fifteen low-resource Indian Languages (ILs) and vice versa. At the outset, all 15 languages are briefed with a short description related to our experimental need. Further, a detailed analysis of Samanantar and OPUS dataset for model building, along with standard benchmark dataset (Flores-200) for fine-tuning and testing, is done as a part of our experiment. Different preprocessing approaches are proposed in this paper to handle the noise of the dataset. To create the system, MOSES open-source SMT toolkit is explored. Distance reordering is utilized with the aim to understand the rules of grammar and context-dependent adjustments through a phrase reordering categorization framework. In our experiment, the quality of the translation is evaluated using standard metrics such as BLEU, METEOR, and RIBES
