Automatic medical image classification is a very important field where the use of AI has the potential to have a real social impact. However, there are still many challenges that act as obstacles to making practically effective solutions. One of those is the fact that most of the medical imaging datasets have a class imbalance problem. This leads to the fact that existing AI techniques, particularly neural network-based deep-learning methodologies, often perform poorly in such scenarios. Thus this makes this area an interesting and active research focus for researchers. In this study, we propose a novel loss function to train neural network models to mitigate this critical issue in this important field. Through rigorous experiments on three independently collected datasets of three different medical imaging domains, we empirically show that our proposed loss function consistently performs well with an improvement between 2%-10% macro f1 when compared to the baseline models. We hope that our work will precipitate new research toward a more generalized approach to medical image classification.

Complex and contact-rich robotic manipulation tasks, particularly those that involve multi-fingered hands and underactuated object manipulation, present a significant challenge to any control method. Methods based on reinforcement learning offer an appealing choice for such settings, as they can enable robots to learn to delicately balance contact forces and dexterously reposition objects without strong modeling assumptions. However, running reinforcement learning on real-world dexterous manipulation systems often requires significant manual engineering. This negates the benefits of autonomous data collection and ease of use that reinforcement learning should in principle provide. In this paper, we describe a system for vision-based dexterous manipulation that provides a "programming-free" approach for users to define new tasks and enable robots with complex multi-fingered hands to learn to perform them through interaction. The core principle underlying our system is that, in a vision-based setting, users should be able to provide high-level intermediate supervision that circumvents challenges in teleoperation or kinesthetic teaching which allow a robot to not only learn a task efficiently but also to autonomously practice. Our system includes a framework for users to define a final task and intermediate sub-tasks with image examples, a reinforcement learning procedure that learns the task autonomously without interventions, and experimental results with a four-finger robotic hand learning multi-stage object manipulation tasks directly in the real world, without simulation, manual modeling, or reward engineering.

The task of locating and classifying different types of vehicles has become a vital element in numerous applications of automation and intelligent systems ranging from traffic surveillance to vehicle identification and many more. In recent times, Deep Learning models have been dominating the field of vehicle detection. Yet, Bangladeshi vehicle detection has remained a relatively unexplored area. One of the main goals of vehicle detection is its real-time application, where `You Only Look Once' (YOLO) models have proven to be the most effective architecture. In this work, intending to find the best-suited YOLO architecture for fast and accurate vehicle detection from traffic images in Bangladesh, we have conducted a performance analysis of different variants of the YOLO-based architectures such as YOLOV3, YOLOV5s, and YOLOV5x. The models were trained on a dataset containing 7390 images belonging to 21 types of vehicles comprising samples from the DhakaAI dataset, the Poribohon-BD dataset, and our self-collected images. After thorough quantitative and qualitative analysis, we found the YOLOV5x variant to be the best-suited model, performing better than YOLOv3 and YOLOv5s models respectively by 7 & 4 percent in mAP, and 12 & 8.5 percent in terms of Accuracy.

Machine learning is the study of computer algorithms that can automatically improve based on data and experience. Machine learning algorithms build a model from sample data, called training data, to make predictions or judgments without being explicitly programmed to do so. A variety of wellknown machine learning algorithms have been developed for use in the field of computer science to analyze data. This paper introduced a new machine learning algorithm called impact learning. Impact learning is a supervised learning algorithm that can be consolidated in both classification and regression problems. It can furthermore manifest its superiority in analyzing competitive data. This algorithm is remarkable for learning from the competitive situation and the competition comes from the effects of autonomous features. It is prepared by the impacts of the highlights from the intrinsic rate of natural increase (RNI). We, moreover, manifest the prevalence of the impact learning over the conventional machine learning algorithm.

评估人工智能系统的可信赖性需要许多不同学科的知识。这些学科不一定在它们之间共享概念，并且可能使用具有不同含义的单词，甚至使用相同的单词不同。此外，来自不同学科的专家可能不知道其他学科中很容易使用的专业术语。因此，评估过程的核心挑战是确定来自不同学科的专家何时谈论相同的问题，但使用不同的术语。换句话说，问题是将问题描述（又称问题）分组具有相同的语义含义，但使用略有不同的术语进行了描述。在这项工作中，我们展示了我们如何采用自然语言处理的最新进展，即句子嵌入和语义文本相似性，以支持此识别过程，并弥合跨学科专家团队中评估人工智能系统可信赖的跨学科沟通差距。

Covid-19大流行，仍然是未知的，是一个重要的开放问题。有猜测蝙蝠是可能的起源。同样地，有许多密切相关的（电晕）病毒，例如SARS，发现通过练习圈传递。对潜在的载体和致命病毒发射器的不同主体的研究对于了解，减轻和预防当前和未来的流行性至关重要。在冠状病毒中，表面（S）蛋白或尖峰蛋白是确定宿主特异性的重要组成部分，因为它是病毒与宿主细胞膜之间的接触点。在本文中，我们将超过五千个冠状病毒的刺激蛋白序列分类，将它们分离成艾滋病，蝙蝠，骆驼，猪，人类和奶酪中明显宿主的集群，以命名几个。我们提出了一种基于众所周知的位置重量矩阵（PWM）的特征嵌入，我们呼叫PWM2VEC，并用于从这些冠状虫病毒的尖峰蛋白序列产生特征向量。虽然我们的嵌入受到PWMS在生物应用中的成功，例如确定蛋白质功能，或识别转录因子结合位点，但我们是在来自病毒序列的宿主分类的上下文中使用PWM的第一个（我们的知识）生成固定长度的特征矢量表示。现实世界数据的结果显示，与使用PWM2VEC，与基线模型相比，我们能够相当良好地执行。我们还使用信息增益来测量不同氨基酸的重要性，以显示对预测给定冠状病毒的宿主来说重要的氨基酸。
