With massive data, complex information, and the increasingly expanding huge stock pool, it is always difficult for investors to quickly and accurately choose stocks with good inherent value and predictable constant growth. Therefore, stock analysis before investment is vital. In this paper, by applying classical K-means clustering algorithm in data mining, 100 US stocks randomly selected from Yahoo Finance are first classified into different performance groups based on their historical trading data in the recent one year, then detailed analysis of the typical stocks in each performance group is given from the perspective of technical analysis, attempting to find some important features for simple and rapid evaluation of stock investment value, in addition, corresponding investment advice is also proposed based on some statistical analysis index. © COPYRIGHT SPIE.

Large Language Models (LLMs) demonstrate significant capabilities in processing natural language data, promising efficient knowledge extraction from diverse textual sources to enhance situational awareness and support decision-making. However, concerns arise due to their susceptibility to hallucination, resulting in contextually inaccurate content. This work focuses on harnessing LLMs for automated Event Extraction, introducing a new method to address hallucination by decomposing the task into Event Detection and Event Argument Extraction. Moreover, the proposed method integrates dynamic schema-aware augmented retrieval examples into prompts tailored for each specific inquiry, thereby extending and adapting advanced prompting techniques such as Retrieval-Augmented Generation. Evaluation findings on prominent event extraction benchmarks and results from a synthesized benchmark illustrate the method’s superior performance compared to baseline approaches. © 2024, CC BY.

Detecting brain tumours is complex due to the natural variation in their location, shape, and intensity in images. While having accurate detection and segmentation of brain tumours would be beneficial, current methods still need to solve this problem despite the numerous available approaches. Precise analysis of Magnetic Resonance Imaging (MRI) is crucial for detecting, segmenting, and classifying brain tumours in medical diagnostics. Magnetic Resonance Imaging is a vital component in medical diagnosis, and it requires precise, efficient, careful, efficient, and reliable image analysis techniques. The authors developed a Deep Learning (DL) fusion model to classify brain tumours reliably. Deep Learning models require large amounts of training data to achieve good results, so the researchers utilised data augmentation techniques to increase the dataset size for training models. VGG16, ResNet50, and convolutional deep belief networks networks extracted deep features from MRI images. Softmax was used as the classifier, and the training set was supplemented with intentionally created MRI images of brain tumours in addition to the genuine ones. The features of two DL models were combined in the proposed model to generate a fusion model, which significantly increased classification accuracy. An openly accessible dataset from the internet was used to test the model's performance, and the experimental results showed that the proposed fusion model achieved a classification accuracy of 98.98%. Finally, the results were compared with existing methods, and the proposed model outperformed them significantly.

Organizations require virtual communication because efficient communication is essential to successful company operations. Among the features of virtual communication typically email communication, which is textual and asynchronous, meaning that the sender and the recipient do not encounter it simultaneously. Email can be troublesome because it eliminates in-person interactions, which can distort our capacity to develop interpersonal cues that are essential for communicating, exchanging information, and establishing trust. The proposed research is aimed to investigate the adaptability of emotional cues in email communication. A deep learning model is built to extract the emotional cues in email considering multiple parameters like text, audio, video and context of communication. The proposed models achieve accuracy of 96.86%, precision of 97.44%, and sensitivity of 97.69% which is highest score when compared to other existing models. © 2024 IEEE.

In the rapidly evolving landscape of cybercrime, ensuring the authenticity and traceability of digital evidence has become paramount. This paper explores the integration of blockchain technology with digital forensics as a novel approach to address these concerns. Blockchain, with its inherent characteristics of immutability and decentralization, can offer significant advancements in ensuring tamper-proof storage and chronological verification of forensic artifacts. By merging these two domains, we introduce a framework that not only bolsters the authenticity of digital evidence but also facilitates a robust traceability mechanism. Through a detailed case study, we demonstrate the practicality and effectiveness of this integrated approach, highlighting its potential to revolutionize current forensic methodologies. However, we also delve into the challenges posed, such as scalability, privacy, and legal implications, and suggest future research avenues. Leveraging blockchain technology in the realm of digital forensics has the potential to redefine evidence integrity and the forensic investigation landscape.

Unlike single biometric systems, multi-instance biometric systems can reduce the risk of user privacy leakage. Meanwhile, maintaining biometric security also requires template protection. However, there is still limited study focusing on template protection in multi-instance biometrics. To address such issues, this paper proposes a method for multi-instance finger vein template protection. In this work, the vein features of different finger instances are extracted at feature fusion and image fusion levels using Gabor filter method, respectively. For feature transformation, the Gabor feature blocks are transformed with Bloom filters to extract the finger vein template for secure storage and verification. When analyzing the performance, the experiments are mainly conducted with the constant key scenario to be compared with performance of the baseline Gabor feature extraction method and the genuine key scenario. It is shown that this proposed method effectively improves system performance, with equal error rate (EER) as low as 5.00% in constant key scenario, while maintaining zero error rate in genuine key scenario. Besides, the proposed method is also examined for the properties of unlinkability and irreversibility as required for a template protection method. © 2022 IEEE.

Next Point-of-Interest (POI) recommendation has become a crucial task in Location-Based Social Networks (LBSNs), which provide personalized recommendations by predicting the user’s next check-in locations. Commonly used models including Recurrent Neural Networks (RNNs) and Graph Convolutional Networks (GCNs) have been widely explored. However, these models face significant challenges, including the difficulty of capturing the hierarchical and tree-like structure of POIs in Euclidean space and the sparsity problem inherent in POI recommendations. To address these challenges, we propose a Hyperbolic Variational Graph Auto-Encoder (HVGAE) for next POI recommendation. Specifically, we utilize a Hyperbolic Graph Convolutional Network (Hyperbolic GCN) to model hierarchical structures and tree-like relationships by converting node embeddings from euclidean space to hyperbolic space. Then we use Variational Graph Auto-Encoder (VGAE) to convert node embeddings to probabilistic distributions, enhancing the capture of deeper latent features and providing a more robust model structure. Furthermore, we combine the Mamba4Rec recommender and Rotary Position Embedding (RoPE) and propose Rotary Position Mamba (RPMamba) to effectively utilize POI embeddings rich in sequential information, which improves the accuracy of the next POI recommendation. Extensive experiments on three public datasets demonstrate the superior performance of the HVGAE model. © 2025 Copyright held by the owner/author(s).
