The integration of machine learning (ML) into mobile applications presents unique challenges, particularly in resource-constrained environments such as iOS devices. Skin lesion classification is a critical task in dermatology, where accurate and efficient diagnostic tools can significantly aid in early detection of malignant lesions. This study aims to implement a machine learning-based iOS mobile application and develop a binary classification model for skin lesion images to determine whether a lesion is malignant. The research utilized Create ML to develop a convolutional neural network optimized for iOS, employing a transfer learning approach. A logistic regression model was cascaded with the convolutional neural network N to enhance classification accuracy. The model's performance was assessed through various validation metrics, ensuring its robustness and efficiency within the constraints of mobile hardware. A curated dataset from the International Skin Imaging Collaboration archive was used for training and testing. The model achieved an accuracy of 92%, a precision of 90%, a recall of 93%, and an F1-score of 91% in classifying skin lesions. These metrics validate the model's efficacy in identifying malignant lesions. Data curation involved collecting, labeling, and preparing a dataset from publicly available sources, ensuring the inclusion of diagnostically relevant features. The final model was integrated into an iOS application using Core ML and Vision frameworks. The developed application demonstrates reliable performance in classifying skin lesions with high accuracy on iOS devices. The inclusion of comprehensive performance metrics justifies the efficacy of the proposed approach. Future work will explore enhancements in model architecture and object detection capabilities to further improve diagnostic precision and application usability. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Currently, the 4G network service has caused massive digital growth in high use. Video calling has become the go-to Internet application for many people, downloading even huge files in minutes. Everyone is looking for and buying only 4G Subscriber Identity Module (SIM)-capable mobiles. In this case, the expectation of 5G has increased in line with 2G, 3G, and 4G, where the G stands for generation, and it does not indicate Internet or Internet speed. 5G includes next-generation features that are more advanced than those available in 4G network services. The main objective of 5G is uninterrupted telecommunication service in hybrid energy storage system. This paper proposes an intelligent networking model to obtain the maximum energy efficiency and Artificial Intelligence (AI) automation of 5G networks. There is currently an issue where the signal cuts out when crossing an area with one tower and traveling to an area with another tower. The problem of “call drop”, where the call is disconnected while talking, is not present in 5G. The proposed Intelligent Computational Model (ICM) model obtained 96.31% network speed management, 90.63% battery capacity management, 92.27% network device management, 93.57% energy efficiency, and 88.41% AI automation.

The performance for communication in a real-time mobile communication system is contingent upon the distribution of spectrum among the devices and the best antenna selection, which is determined by the Direction of Arrival and the power spectrum of the antenna characteristics. The prediction and directivity of signal spectrum level based on antenna parameters were the primary areas of research attention. Generally speaking, a number of techniques anticipate the antenna spectrum level by comparing the parameters of the channel capacity and the device communication signal strength. The best selection model for the communication antenna parameter's spectrum range was used to process this. In this case, improving mobile communication performance for the entire system is thought to be the primary goal of the study. To analyze the effectiveness of antenna optimization and its performance, this has been done by testing the beamforming method's parameter under a variety of scenarios. The Boundary Assisted Antenna Selection (BAAS) technique was employed in this to minimize the number of iterations required for feature learning and antenna selection. In order to create an improved beamforming model for parallel antenna parameter estimation, this was processed through the hybridization of multi-objective optimization. Using the combination of Beamforming with BAAS based antenna selection approach, which chooses the optimal feature attribute of the antenna power spectrum with Direction of Arrival (DOA), this can further accelerate performance. Metrics like the quantity of allocated spectrum, power factor, throughput, spectrum range of capacity, and other relevant factors can be used to validate the effectiveness of the suggested strategy. The results show that the proposed work achieved approximately 7.27% of Spectral efficiency (bps), Signal Power (dB) and Interference (dB). © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Natu

Unveiling Deceptive Intentions: Insights from Fixations and Pupil Size

引用

Proceedings of the ACM on Human-computer Interaction 2024年第ETRA期8卷 1-17页

作者： Foucher, Valentin Huckauf, Anke Department of General Psychology Faculty of Engineering Computer Science and Psychology Ulm University Germany

Recognition of deceptive intentions from the eyes has been of appealing interest in the last decades but is still unresolved. Here, we report the development of a paradigm based on the Concealed Information Test enabling the study of various kinds of deception, that is, faking and concealing. Based on a card game, we compared fixation as well as pupil behaviour while participants were instructed to fake, conceal, or tell the truth. We realized two different layouts of stimulus presentation. Fixations differed between concealing versus faking and telling the truth;pupil size additionally unveiled the object of deception. We infer that various kinds of deceptive behaviour must be carefully distinguished, and contribute to how to use gaze measures as indicators of deceptive intentions. © 2024 Copyright held by the owner/author(s).
