We propose an ensemble approach to predict the labels in linear programming word problems. The entity identification and the meaning representation are two types of tasks to be solved in the NL4Opt competition. We propose the ensembleCRF method to identify the named entities for the first task. We found that single models didn't improve for the given task in our analysis. A set of prediction models predict the entities. The generated results are combined to form a consensus result in the ensembleCRF method. We present an ensemble text generator to produce the representation sentences for the second task. We thought of dividing the problem into multiple small tasks due to the overflow in the output. A single model generates different representations based on the prompt. All the generated text is combined to form an ensemble and produce a mathematical meaning of a linear programming problem.

现有的数据依赖性哈希方法使用具有数百万个参数的大型骨干网络,并且计算复杂。现有的知识蒸馏方法使用深(教师)模型的逻辑和其他功能,并将其作为紧凑型(学生)模型的知识,这要求教师的网络在上下文中与上下文中的学生模型平行进行微调。在目标环境中培训老师需要更多的时间和计算资源。在本文中,我们提出了不知道知识蒸馏的上下文,该蒸馏使用教师模型的知识而不在目标环境上进行微调。我们还提出了一种新的高效学生模型架构,用于知识蒸馏。提出的方法遵循两步过程。第一步涉及在不知道教师模型的不知道知识蒸馏的情况下预先培训学生模型。第二步涉及在图像检索的上下文上微调学生模型。为了显示拟议方法的功效,我们比较了检索结果。参数和否。在不同检索框架下,学生模型的运营与教师模型的运作,包括Deep Cauchy Hashing(DCH)和中央相似性量化(CSQ)。实验结果证实,所提出的方法在检索结果与效率之间提供了有希望的权衡。本文中使用的代码通过\ url {https://github.com/satoru2001/cukdfir}公开发布。

使用深度学习的图像的手写词识别是一个有希望性能的活跃研究区域。IT实际情况,由于安全原因,可能需要在压缩域中处理手写图像。然而,对于压缩图像的处理仍然非常有限的深度学习的利用。通过在深度学习中的最新进展中,在压缩域中处理文档图像的需要,我们提出了一个HWRCNET模型,用于JPEG压缩域中的手写字识别。所提出的模型结合了基于卷积神经网络(CNN)和双向长短期存储器(BILSTM)的经常性神经网络(RNN)。基本上,我们使用压缩域图像训练模型,并遵守89.05%字识别精度和13.37%的字符错误率非常有吸引力的性能。

近年来,神经网络已显示出巨大的增长,以解决许多问题。已经引入了各种类型的神经网络来处理不同类型的问题。但是,任何神经网络的主要目标是使用层层次结构将非线性可分离的输入数据转换为更线性可分离的抽象特征。这些层是线性和非线性函数的组合。最流行和常见的非线性层是激活功能(AFS),例如Logistic Sigmoid,Tanh,Relu,Elu,Swish和Mish。在本文中,在神经网络中为AFS提供了全面的概述和调查,以进行深度学习。涵盖了不同类别的AFS,例如Logistic Sigmoid和Tanh,基于RELU,基于ELU和基于学习的AFS。还指出了AFS的几种特征,例如输出范围,单调性和平滑度。在具有不同类型的数据的不同网络的18个最先进的AF中,还进行了性能比较。提出了AFS的见解,以使研究人员受益于进一步的研究和从业者在不同选择中进行选择。用于实验比较的代码发布于:\ url {https://github.com/shivram1987/activationfunctions}。

卷积神经网络(CNN)通常是使用基于随机梯度下降(SGD)优化技术训练的。现有的SGD优化器通常会遭受最小值和最低振荡的过度损失。在本文中,我们提出了一种新方法,以下内容称为Adainject,以将二阶时刻注入一阶时刻,以称为梯度下降优化器。具体而言,参数的短期更改被用作重量,以在更新规则中注入二阶时刻。 Adainject优化器控制参数更新,避免了最小值的过度换档,并减少了最小值接近的振荡。提出的方法本质上是通用的,可以与任何现有的SGD优化器集成。通过直观地解释了Anainject优化器的有效性以及一些玩具示例。我们还显示了拟议的基于注射的优化器的收敛性。此外,我们通过广泛的实验与最新的优化器(即Adaminject,diffgradinject,radaminject和Adabeliefinject在四个基准数据集中)一起描述了ADAIN方法的功效。实验中使用了不同的CNN模型。在CIFAR10数据集上使用resnext29模型,使用diffgradinject Optimizer观察到TOP-1分类错误率$ 16.54 \%$的最高提高。总体而言,我们通过提出的ADAIN方法观察到现有优化器的性能提高非常有希望。该代码可在:\ url {https://github.com/shivram1987/adainject}中获得。

随机梯度体面(SGD)是深神经网络成功背后的核心技术之一。梯度提供有关功能具有最陡变化率的方向的信息。基本SGD的主要问题是通过梯度行为而对所有参数的相等大小的步骤进行更改。因此,深度网络优化的有效方式是为每个参数进行自适应步骤尺寸。最近,已经进行了几次尝试,以改善梯度下降方法,例如Adagrad,Adadelta,RMSProp和Adam。这些方法依赖于平方过去梯度的指数移动平均线的平方根。因此,这些方法不利用梯度的局部变化。在本文中,基于当前和立即梯度(即,差异)之间的差异提出了一种新颖的优化器。在所提出的差异优化技术中,以这样的方式调整步长,使得它应该具有更大的梯度改变参数的较大步长,以及用于较低梯度改变参数的较低步长。收敛分析是使用在线学习框架的遗憾方法完成。在本文中进行严格的分析超过三种合成复合的非凸功能。图像分类实验也在CiFar10和CiFAR100数据集上进行,以观察漫反射的性能,相对于最先进的优化器,例如SGDM,Adagrad,Adadelta,RMSProp,Amsgrad和Adam。基于基于单元(Reset)的基于卷积神经网络(CNN)架构用于实验中。实验表明,Diffgrad优于其他优化器。此外,我们表明差异对使用不同的激活功能训练CNN的均匀良好。源代码在https://github.com/shivram1987/diffgrad公开使用。

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
