The active involvement of different demographic entities, whether positive or negative, demands effective identification of diverse populations. One way to quickly perform this identification is by segregating individuals based on their soft biometric attributes such as race and gender. Further, the soft biometric recognition technology has the potential to enhance individual privacy by providing a less invasive identification mode than conventional biometric methods. For example, a specific disbursement of government benefits might not require the exact identity of a person but only soft biometric attributes for its actual distribution. Secondly, the correct identification of race and gender can restrict the identity search space in which we need to look for an imposter. However, despite tremendous literature on identity recognition, limited work has been done to identify soft biometric attributes in challenging evaluation settings accurately. Therefore, in this research, for the first time, we have performed extensive experiments to benchmark the effectiveness of pure convolutional networks and attention networks to identify gender and ethnicity in the in-distribution and out-of-distribution (OOD) settings. We employed diverse face datasets to benchmark our methods, including UTKFace and FairFace. In contrast to the general understanding that OOD images lead to poor performance, we observe significant performance in identifying soft biometric attributes, including race and gender classification. © 2024 IEEE.

Task 2 of eRisk shared tasks in CLEF 2024 aims to develop text mining solutions for early prediction of anorexia using sequentially posted texts over social media. Anorexia is an eating disorder, a kind of mental illness, where people have distorted perceptions of their body weights and accordingly manipulate their food habits, which often results in deficient body weight. The aim here is to identify anorexia by processing the interactions over social media of an individual through text mining models. The organisers provided training data with ground truths for training the models and test data for evaluating their performance. The BioNLP research group at the Indian institute of science Education and Research Bhopal (IISERB) participated in Task 2 and submitted five runs for five text mining frameworks. Five different classifiers and individual feature engineering techniques were used to develop frameworks. The bag-of-words model and transformer-based embedding were used as features for individual classifiers. The performance of multiple classifiers was evaluated using the training corpus. Then Random Forest, Adaptive Boosting, Logistic Regression, Support Vector Machine (SVM), and Longformer classifiers were chosen to run on the test set. Experimental results show that SVM and AdaBoost classifiers using the TF-IDF-based weighting schemes achieved the highest precision score among all submitted runs in Task 2 of eRisk 2024. However, the performance of our models in terms of the other metrics, like recall, f-score, ERDE, etc., is not reasonably good compared to the other runs. Hence, we plan to develop transformer-based embeddings from scratch using data collected from multiple social media platforms. © 2024 Copyright for this paper by its authors.

In the financial sector, credit card fraud is a common issue that costs both people and organizations a lot of money. The ability of machine learning algorithms to automatically identify patterns and anomalies from big datasets has made them a common method for fraud detection. In order to increase the detection of credit card fraud, we suggest an improved Bayesian random forest classifier in this article. By using Bayesian optimization to choose the ideal hyperparameters for the model, we handle the difficulties and restrictions of conventional random forest classifiers. Using an openly accessible dataset on credit card fraud, the proposed method is assessed and contrasted with other cutting-edge approaches. By obtaining an accuracy of 99.6% and an area under the curve (AUC) of 0.99, our findings demonstrate that the suggested optimized Bayesian random forest classifier outperforms conventional random forest and other benchmark methods. We also examine the significance of features in fraud identification in order to show the model’s interpretability. Finally, we discuss the suggested strategy’s drawbacks and potential future developments. Our study aids in the creation of reliable and effective fraud detection tools for the finance sector. The suggested approach can be used as a decision support tool for fraud analysts and detectives and can be applied to a variety of fraud detection issues beyond credit card fraud. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Drug abuse poses a pressing societal issue and limits the success of face recognition algorithms. Further, when the faces are acquired in an unconstrained environment, they get affected by several environmental factors including snow, noise, and blur. One prominent limitation of the existing research is that no work has been done to mitigate the impact of drug abuse on deep face recognition. Further, the problem became complicated in the presence of input corruption. Through this study, we aim to fill the gap by investigating the effects of drug-induced facial alterations coupled with input corruptions on deep face recognition. Our study indicates that drug alteration drastically alters facial features and on top of that the corruption further degrades the image quality and hence leads to poor performance by deep face recognition networks. Therefore, the one question we asked inspired by the success of generative networks is whether these models can help mitigate the impact of drug abuse and image corruption to boost performance. Through experiments simulating real-world scenarios, we demonstrate several interesting observations about the success of generative models including diffusion and generative architectures. The efficacy of these models is not only observed for face recognition but also for the improvement of gender classification performance. To the best of our knowledge mitigation of illicit drug abuse is not explored in the literature and hence, this research contributes to enhancing the reliability of face recognition systems amidst the challenges posed by drug abuse, thus advancing both understanding and application in practical settings. © 2024 IEEE.

A novel approach for image retrieval in remote sensing using vision-language-based image caption generation

引用

Multimedia Tools and Applications 2025年第6期84卷 2985-3014页

作者： Yadav, Prem Shanker Tyagi, Dinesh Kumar Vipparthi, Santosh Kumar Department of Computer Science and Engineering Malaviya National Institute of Technology Rajasthan Jaipur302017 India School of Artificial Intelligence and Data Engineering Indian Institute of Technology Ropar Punjab Rupnagar140001 India

Recent advancements in satellite technologies have resulted in the emergence of Remote Sensing (RS) images. Hence, the primary imperative research domain is designing a precise retrieval model for retrieving the most pertinent images based on the query. Present Remote Sensing Image Retrieval (RSIR) systems use visual descriptors to characterize the primitives (such as various land-cover types) that are visible in the images. However, the visual descriptors are inadequate for defining the complicated content of RS images. To solve this problem, a new model is devised for image retrieval based on image captions. The goal is to generate textual illustrations with captions to define relations amongst objects precisely. Here, image captioning is attained based on the vision-language pre-training model. The image captions are utilized for generating features like term frequency-inverse document frequency (TF-IDF), length of text, and Bag of Words. Meanwhile, query text is utilized wherein features like TF-IDF, text length, and Bag of Words are obtained. The similarity between query text features and the image captions features has been computed on the basis of a hybrid similarity measure wherein weights are tuned with the proposed Honey Badger Political Optimizer (HBPO) to retrieve the image. The proposed HBPO provided enhanced efficiency with elevated precision of 93.3%, recall of 93.7%, F1-score of 93.5%, and Recall-Oriented Understudy for Gisting Evaluation (ROUGE) of 0.441. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

The detection of skin cancer holds paramount importance worldwide due to its impact on global health. While deep convolutional neural networks (DCNNs) have shown potential in this domain, current approaches often struggle with fine-grained variability in skin lesion features, imbalanced datasets and inadequate augmentation. The objectives of our study encompass building a model that not only enhances accuracy but also reduces training time and cost, improves dimensionality reduction during classification and segmentation, and is evaluated on larger datasets for robustness. We enhance the learning process using an improved nature-inspired optimisation algorithm tailored specifically for skin cancer classification tasks. This algorithm optimises model parameters to maximise classification accuracy while minimising computational overhead. Our proposed architecture leverages a gold standard dermatological image dataset meticulously curated and validated by experts. This dataset spans eight distinct classes, including actinic keratosis, basal cell carcinoma, melanoma, nevus, and others, ensuring a diverse representation of skin conditions. The balanced class distribution in the training and test sets enables fair evaluation and robustness assessment of our deep learning models. The developed algorithm showcases novelty in its approach, contributing to advancements in early skin cancer detection technologies. This study introduces an optimised deep learning model designed for the early detection of skin cancer, achieving a notable accuracy of 97.48%. Our study aims to contribute significantly to the medical field by providing a reliable and efficient tool for dermatologists and healthcare practitioners to assist in diagnosing skin conditions accurately and promptly, ultimately improving patient outcomes and healthcare efficiency. © (2025), (Indian Academy of sciences).

This systematic review gave special attention to diabetes and the advancements in food and nutrition needed to prevent or manage diabetes in all its forms. There are two main forms of diabetes mellitus: Type 1 (T1D) and Type 2 (T2D). The loss of beta cells brought on by an autoimmune reaction causes the pancreas to be unable to produce enough insulin, which leads to Type 1 diabetes. A deficiency of insulin could arise as the illness worsens. The most frequent cause is a combination of excessive body weight and inadequate exercise. Currently, 90–95% of patients have Type 2 diabetes mellitus (T2DM). Age-specific normal blood sugar ranges exist and knowing them is crucial for determining a target blood sugar level that is both healthy and appropriate. The main takeaway is that diet regimens ought to be tailored to the patient’s requirements and should account for their capacity for change. Carbohydrates are the nutrients that have the biggest impact on the rise in blood glucose. In this paper, we have proposed a novel method for glucose monitoring and diet recommendations for diabetic patients using fog computing. A paradigm known as fog computing makes use of the benefits that come from using both cloud and edge devices to support modern computing systems by offering high-quality services, cutting latency, facilitating mobility, supporting multi-tenancy, and many other features. © 2025 by Begell House, Inc.
