Fingerprint authentication is the most sophisticated method of all biometric techniques and has been thoroughly verified through various applications. Fingerprint matching has been done using several fingerprint recognition techniques. The methods for matching fingerprints have changed significantly over time, but Euclidean distance is still widely used since it is efficient and straightforward. Euclidean distance is still used in minutiae-based fingerprint matching to produce accurate results. The computational geometry, image processing, and patter recognition fields all make substantial use of Euclidean distance, a fundamental distance matching approach. The purpose of this work is to highlight the importance of normalization in improving contrast, particularly in noisy fingerprint photographs where accuracy is critical. We analyzed how to make fingerprint matching more robots against a reference template by utilizing Euclidean distance between small spots. We also analyzed algorithm’s effectiveness in producing dependable and accurate fingerprint matching results using MATLAB. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Big data has emerged very fast, and this has brought both opportunities and problems that are related to the application of deep learning. This paper explores how deep learning can be implemented using big data and in particular the Apache Mahout library. Unlike most other machine learning tools, Mahout can perform distributed computation, especially while using the MapReduce frameworks including Apache Hadoop and Apache Spark. However, this study does not only focus on the explanation of the need for Mahout's integration and employment but also carries out a high-fidelity argument on how deep learning algorithms can be incorporated in the Mahout framework to optimize the manipulation of large and complicated datasets. Mahout-based contributions include the comparative analysis of key deep learning paradigms including distributed processing, parallel processing and transfer learning. This paper also includes examples of the Mahout deep learning integration use and its application in real contexts. This article describes the challenges that currently organizations face in handling big data and indeed, the potential threats these challenges pose to the success of deep learning techniques when used in organizations' big data processing and analysis. © 2024 IEEE.

The development of legal records requires extra time and their absurd length raises the need for programmed legal record handling frameworks. One of the handling steps is to recognize the essence of the reports expressions for legitimate case records. A computerized framework that could help a legal professional in anticipating the result of a case would help facilitate the legal interaction. For such a framework to be essentially valuable, expectations by the framework ought to be reasonable. To advance exploration in growing such a framework, this paper presents the Indian Legal Judgment Dataset (ILJD). ILJD is a huge corpus of 35k Indian Supreme Legal disputes commented on with unique court choices. A part of the corpus (a different test set) is commented on with best quality level clarifications by lawful specialists. © 2023 IEEE.

In self-organized aggregation, that no specific aggregated sites are known makes it intractable for powerless robots. In this paper, we formulate the aggregation problem as a shape construction process in which agent's behavior is determined by the positional relationship with its neighbors. This paper presents a novel self-organizing strategy to gather a swarm of homogeneous robots into rectangular clusters without any prior target knowledge. Moreover, the robots are unable to communicate with each other and have a minimal range of perception, which is the smallest value to avoid collision between individuals. By the definition of semi-stable/stable states, we design a distributed probabilistic aggregation algorithm that takes advantage of the temporal and spatial perception of robots. A new metric is introduced to measure the similarity of aggregated clusters and rectangles. This algorithm is evaluated via a series of simulation experiments running on a group of up to 1000 agents, showing that it allows robot swarms to obtain the desired aggregation. © 2023 Technical Committee on Control Theory, Chinese Association of Automation.

Nowadays there are many research efforts in the field of artificial intelligence applied in all the fields of robotics. There are developed and trained new models both supervised and unsupervised learning. ln order to be able to get a reliable final product, a very important step is modeling and simulation. This paper focuses on the analysis of a quadruped robot, Stanford Pupper type, for which the mathematical model for the locomotor system was developed in order to be then implemented in a simulator that allows the development of machine learning algorithms for training it. There can be implemented in the simulator various use cases, like: learning to walk both supervised and unsupervised scenarios, learning to navigate on a zone with uneven surface and with small obstacles, or learning to climb stairs or other big obstacles. © 2023 ITMA.

A novel approach to identify parkinson’s disease and other similar neural stress by analysing keystrokes on modern active devices with ensemble classification

Motor skills (related to the motor nerve) and neurocognitive disorders affect humans’ typing ability to an extent that is noticeable while using a keyboard, smartphone, or other electronic gadgets. These two medical conditions are Parkinson’s disease (PD), caused by malfunctions of the motor nerve, and neurocognitive disorder, caused by a deficiency of organismic responses to stimuli. A mild symptom of PD, change in fine motor skills during typing, is reflected heavily in keystroke patterns during the early stages. Similarly, Emotional stress (ES) expresses a neurocognitive disorder that affects cognitive abilities as well. Early symptoms of this disorder are reflected in the keystroke patterns according to their severity. As there is no such pathological examination, it is challenging to perceive and measure the development of such disorders already developed in human behaviour as a disease. Furthermore, early screening of these diseases is essential for future diagnosis and preventing fatal consequences, since both are progressive illnesses. A modest attempt is made here to detect two such neurodegenerative disorders in humans using the way they type, formally known as Keystroke dynamics (KD). In this study, a bootstrapped-based homogeneous ensemble classification method has been proposed to address the uncertain performance and uneven distribution of classes for the detection of such medical conditions using users’ typing tendencies. For this purpose, two recent benchmark datasets were used for the validation and confirmation of operational improvements of the proposed method, which have been validated qualitatively and quantitatively. As a result, sensitivity/specificity of 0.82/0.78 in detecting PD and 0.98/0.98 in ES have been achieved, which is robust and accurate in a more realistic evaluation. The proposed framework explores the possibilities of implementing it in web-based systems, which has significant benefits. A better diagnosis, early detection at home

As a core hardware in the development of satellite cryptographic devices, FPGAs are required to go through extensive functional correctness validation before finally bound to the channel equipment. However, the diversity of satellite communication systems and the bad habits of some developers often lead to the ineffective reuse of verification module. To improve the reuse rate of verification module and the verification efficiency of cryptographic devices, we propose an FPGA partial reconfiguration method based on minimum functional unit division (MFD). First, we present a formal description of the minimum functional unit (MFU), which is a collection of modules that are highly cohesive and atomized with respect to the system's entire functional design. Then a reconfiguration method based on MFU global search is given as an implementation of MFD. Next, the performance of MFD is analyzed in terms of reconfiguration granularity, implementation complexity, extensibility and module reuse rate, and the analysis results show a good performance in optimizing FPGA partial reconfiguration design. Finally, we design a MFD based satellite cryptographic device verification platform, in which the hardware interface, communication protocol, cryptographic algorithm and other functional modules are selected as MFU to complete the partial reconfiguration design. The design of the platform based on MFD shows the practicability of MFD, which can provide theoretical guidance for further applying FPGA partial reconfiguration technology in satellite cryptographic device verification platform. © 2023 SPIE.
