在本文中,我们讨论了用分层,细粒度标记标记不同类型的侵略和“上下文”的分层的多语言数据集的开发。这里,这里,这里由对话线程定义,其中发生特定的评论以及评论对先前注释执行的话语角色的“类型”。在此处讨论的初始数据集(并作为逗号@图标共享任务的一部分提供),包括四种语言的15,000名注释评论 - Meitei,Bangla,Hindi和印度英语 - 从各种社交媒体平台收集作为Youtube,Facebook,Twitter和电报。正如通常在社交媒体网站上,大量这些评论都是多语种的,主要是与英语混合的代码混合。本文给出了用于注释的标签的详细描述以及开发多标签的过程的过程,该方法可用于标记具有各种侵略和偏差的评论,包括性别偏见,宗教不宽容(称为标签中的公共偏见),类/种姓偏见和民族/种族偏见。我们还定义并讨论已用于标记通过评论执行的异常发挥作用的标记的标签,例如攻击,防御等。我们还对数据集的统计分析以及我们的基线实验的结果进行了发展使用DataSet开发的自动攻击识别系统。

Part of Speech (POS) tagging is crucial to Natural Language Processing (NLP). It is a well-studied topic in several resource-rich languages. However, the development of computational linguistic resources is still in its infancy despite the existence of numerous languages that are historically and literary rich. Assamese, an Indian scheduled language, spoken by more than 25 million people, falls under this category. In this paper, we present a Deep Learning (DL)-based POS tagger for Assamese. The development process is divided into two stages. In the first phase, several pre-trained word embeddings are employed to train several tagging models. This allows us to evaluate the performance of the word embeddings in the POS tagging task. The top-performing model from the first phase is employed to annotate another set of new sentences. In the second phase, the model is trained further using the fresh dataset. Finally, we attain a tagging accuracy of 86.52% in F1 score. The model may serve as a baseline for further study on DL-based Assamese POS tagging.

6D object pose estimation has been a research topic in the field of computer vision and robotics. Many modern world applications like robot grasping, manipulation, autonomous navigation etc, require the correct pose of objects present in a scene to perform their specific task. It becomes even harder when the objects are placed in a cluttered scene and the level of occlusion is high. Prior works have tried to overcome this problem but could not achieve accuracy that can be considered reliable in real-world applications. In this paper, we present an architecture that, unlike prior work, is context-aware. It utilizes the context information available to us about the objects. Our proposed architecture treats the objects separately according to their types i.e; symmetric and non-symmetric. A deeper estimator and refiner network pair is used for non-symmetric objects as compared to symmetric due to their intrinsic differences. Our experiments show an enhancement in the accuracy of about 3.2% over the LineMOD dataset, which is considered a benchmark for pose estimation in the occluded and cluttered scenes, against the prior state-of-the-art DenseFusion. Our results also show that the inference time we got is sufficient for real-time usage.

Biomedical image segmentation is one of the fastest growing fields which has seen extensive automation through the use of Artificial Intelligence. This has enabled widespread adoption of accurate techniques to expedite the screening and diagnostic processes which would otherwise take several days to finalize. In this paper, we present an end-to-end pipeline to segment lungs from chest X-ray images, training the neural network model on the Japanese Society of Radiological Technology (JSRT) dataset, using UNet to enable faster processing of initial screening for various lung disorders. The pipeline developed can be readily used by medical centers with just the provision of X-Ray images as input. The model will perform the preprocessing, and provide a segmented image as the final output. It is expected that this will drastically reduce the manual effort involved and lead to greater accessibility in resource-constrained locations.

与数字计算相比,模拟计算具有吸引力,因为它可以达到更高的计算密度和更高的能源效率。但是,与数字电路不同,由于晶体管偏置偏差,温度变化和有限的动态范围的差异,传统的模拟计算电路不能轻易地在不同的过程节点上映射。在这项工作中,我们概括了先前报道的基于边缘传播的模拟计算框架,用于设计新颖的\ textit {基于形状的模拟计算}(S-AC)电路,这些电路可以轻松地在不同的过程节点上交叉映射。与数字设计类似的S-AC设计也可以缩放以获得精确,速度和功率。作为概念验证,我们展示了实现机器学习(ML)体系结构中通常使用的数学功能的S-AC电路的几个示例。使用电路模拟,我们证明了电路输入/输出特性从平面CMOS 180NM工艺映射到FinFET 7NM工艺时保持健壮。同样,使用基准数据集,我们证明了基于S-AC的神经网络的分类精度在两个过程中映射到温度变化时仍然坚固。

偏差可估算的模拟计算对于实施机器学习(ML)处理器具有不同的功能性能规格具有吸引力。例如,用于服务器工作负载的ML实现专注于计算吞吐量和更快的训练,而Edge设备的ML实现则集中在节能推理上。在本文中,我们证明了使用边缘传播(MP)原理的概括(MP)原理称为基于形状的模拟计算(S-AC)的偏置模拟计算电路的实现。所得的S-AC核心集成了几个接近内存的计算元素,其中包括:(a)非线性激活函数; (b)内部产品计算电路; (c)混合信号压缩内存。使用在180nm CMOS工艺中制造的原型的测量结果,我们证明了计算模块的性能仍然可与晶体管偏置和温度变化保持稳健。在本文中,我们还证明了简单的ML回归任务的偏差量表性。
