This study proposes an innovative diabetes prediction chatbot that utilizes large language models (LLMs) to determine the likelihood of diabetes based on specific patient inputs. Unlike conventional machine learning models and in addition to providing precise, individualized, robust prediction of diabetes augmented by the percentage of its confidence, this chatbot provides detailed text-based explanations for its individual predictions and enhances user's understanding by retrieving and presenting similar cases using case-based reasoning techniques. Utilizing key health indicators such as hypertension status, heart disease presence, smoking history, BMI, HbA1c level, and blood glucose levels, the chatbot not only predicts the presence of diabetes but also educates users about the underlying reasons for each prediction. The system's explanation module promotes transparency and trust in the predictive process. The proposed architecture integrates the retrieval augmented generation (RAG) technique with prompt engineering across multiple LLMs, including Llama 3.1, GPT- 3.5, and Gemma2. This approach augments the chatbot's responses with contextually relevant data from similar past cases, thereby enhancing both relevance and accuracy. Furthermore, RAG minimizes LLM hallucinations while enhancing them with up-to-date, precise, personalized medical information. The objective of this chatbot is to offer healthcare professionals and patients a dependable, educational instrument for early detection of diabetes supported by transparent AI principles. This will have a positive effect on preventative healthcare measures.

Personalized micro video recommendation aims to recommend the micro videos tailored to user preference based on the user’s interaction history with the micro videos, which has drawn increasing attention from both the academic and industrial communities. Existing solutions primarily concentrate on video-level interactions between users and micro videos to model their preferences, and cannot distinguish the finer-grained users’ interactions with various modalities. Ignoring modality-level interactions prevents the full understanding of the user’s true and subtle preferences on micro videos. To this end, in this article, we propose a Contrastive Multimodal Interaction Graph Learning (MVideoRec) model to automatically and explicitly learn the modality-level interaction between users and micro videos for recommendations. Specifically, we designed a graph structure learning module with a sparsification strategy to infer modality-level interaction graph, which will be dynamically and iteratively updated based on the node representations obtained from the node representation learning module. Furthermore, to address the lack of ground truth labels, we propose to generate teacher view from video-level interaction graph and student view from modality-level interaction graph, as well as construct intra-modality and inter-modality contrastive pairwise instances to provide self-supervised signals. Extensive experiments on three real-world micro video datasets validate the effectiveness of MVideoRec. © 2025 Copyright held by the owner/author(s).

Federated Learning (FL) offers a privacy-preserving solution by enabling multiple clients to train a shared model collaboratively without centralizing data. However, the decentralized nature of FL presents challenges, particularly regarding security and performance under adversarial conditions. This paper investigates the effects of poisoning attacks under data heterogeneity. Our experiments evaluate the impact of varying malicious client fractions and poison concentration levels on the accuracy of the model. We explore the effects of poisoning attacks on FedAvg and FedNova models using medical imaging tasks. Our findings reveal that increasing data heterogeneity exacerbates the effects of poisoning, with FedNova demonstrating greater resilience compared to FedAvg. We found that the number of malicious clients plays a more significant role in degrading performance than the ratio of poisoning samples shared by each malicious client, suggesting that even modest levels of poisoning can be tolerated by most algorithms. The study highlights the importance of developing robust defense mechanisms to maintain model performance under adversarial conditions.

The polarization tensor can be used to describe an object presented in an electric field. This is useful in getting accurate image about the object with electrical imaging device or increasing the likelihood of detecting the object with metal detector. Given the first order polarization tensor and the volume of a spheroid, some properties of the spheroid, such as its conductivity and depolarization factor, have not yet been investigated. Thus, this study aims to propose a method to determine the conductivity and depolarization factor of the spheroid, based on its first order polarization tensor and volume. In order to achieve this, the system of nonlinear equations is first derived based on the given first order polarization tensor, before being solved by the Newton's method. Numerical examples are then provided to demonstrate and justify the proposed algorithm. The findings show that the error for the computed conductivity and depolarization factor is small, suggesting that the proposed algorithm is reliable. In addition, the relationship between the spheroid's volume and conductivity is also discussed. The results illustrate an inverse relationship between the conductivity and depolarization factor when considering a positive definite first order polarization tensor. In contrast, for a negative definite first order polarization tensor, the findings reveal a positive correlation between spheroid's conductivity and its volume. The results obtained can then be used to characterize the spheroid based on its first order polarization tensor and also its volume. This provides additional information about the spheroid, which may contribute to the improvement of future techniques in electrical imaging and metal detection.

This research introduces an extensive AI-based predictive analytics framework aimed at improving customer engagement, retention and satisfaction using advanced Machine Learning (ML) and Natural Language Processing (NLP) methodologies. By using XGBoost for churn prediction and BERT-based models for sentiment analysis, the system efficiently handles both structured and unstructured customer data. The methodology involves sophisticated feature engineering, customer segmentation via K-Means clustering, and Customer Lifetime Value (CLV) prediction to aid data-driven business strategies. An NLP-driven chatbot offers real-time, personalized support, response time and improving user experience. Evaluation metrics such as accuracy, precision, recall and F1-score demonstrate the better performance of the proposed system compared to conventional CRM approaches. This work also addresses important issues such as data privacy compliance, algorithmic bias and explainability of AI decision-making. Ethical deployment and transparency of AI are emphasized for building confidence in automated CRM systems. Future evolution will tackle the use of reinforcement learning to facilitate learning-based interaction schemes and federated learning for trusted, decentralized management of data. This architecture does not only provide better CRM functionality but also builds a platform towards intelligent, responsible and scalable solutions for customer relations across industries. © (2025), (Science and Information Organization).

During the dynamic spread of COVID-19 and the looming threat of future pandemics the essential need of precise epidemiological models are indispensable. Key to these algorithms are the estimation of core parameters a pivotal metric indicating pandemic expansion. Yet, existing algorithms often overlook crucial facets such as viral mutations risks. Addressing this gap, we propose an innovative algorithm merging the Susceptible-Infected-Recovered-Dead (SIRD) model with Re-susceptible compartment incorporated by least square method with linear regression approach that ensures the accurate parameter estimation facilitating real-time forecasting. This idea analyzed different countries full lockdown scenario. These incorporation of statistical and mathematical algorithms enhances parameters estimation, forecasting and provides insights into re-susceptibility percentage. The experiments revealed convincing results with the incorporation of statistical and mathematical algorithms enhancing parameter estimation with best R-square values of 0.9902 for country Pakistan exemplifying its vital contribution to pandemic response strategies. Our work offers a vital tool for governments, institutions and individuals grappling with pandemic responded full lockdown policy. © 2025 Elsevier B.V.

Rapid adoptions of Deep Learning (DL) in a broad range of fields led to the development of specialised testing techniques for DL systems, including DL mutation testing. However, existing post-training DL mutation techniques often generate unstable mutants across multiple training repetitions and multiple applications of the same mutation operator. Additionally, while extremely efficient, they generate mutants without taking into account the mutants' sensitivity and killability, resulting in a large number of ineffective mutants compared to pre-training mutants. In this paper, we present a new efficient post-training DL mutation technique, named MUFF, designed to ensure the stability of the mutants and capable of generating killable and sensitive mutants. MUFF implements an automated stability check and introduces two mutation operators, named weight and neuron inhibitors. Our extensive empirical experiments show that MUFF generates mutants with 60%pt and 25%pt higher sensitivity compared to DEEPMUTATION++ and DEEPCRIME, respectively, while also producing mutants that are more stable than those of DEEPMUTATION++ and different from the mutants of DEEPCRIME. Moreover, MUFF preserves the benefits of the post-training mutation technique, being 61 times faster than DEEPCRIME in generating mutants. © 2025, CC BY.

This study highlights the rapid advancements in artificial intelligence (AI) and machine learning (ML), which have transformed the financial sector by enhancing personalised user interactions and customer engagement. An innovative AI-driven framework was proposed to deliver real-time, context-aware, and highly personalised responses for Digital Banking users. The system architecture employs advanced ML models, natural language processing (NLP) techniques, and modern front-end technologies such as React and GraphQL to address the challenges related to data silos, computational demand, and data privacy. ML models such as user segmentation, recommendation, and NLP models work together to analyse user behaviour, predict needs, and generate human-like responses. Utilising React, GraphQL subscriptions, and Edge AI, the front-end layer ensures a seamless and responsive user experience. The experimental results showed a 120% increase in click-through rates, a 180% increase in follow-up actions, and a 70% reduction in average response time, demonstrating significant improvements in user engagement. User satisfaction, measured by the Net Promoter Score, was significantly higher for the personalised system (8.5) than for the traditional system (5.2). The proposed methodology lays the foundation for an agile trust-based financial environment. Future enhancements will focus on explainable AI, multimodal interactions, and blockchain integration to boost transparency, engagement, and data privacy.
