The rapid advancement of generative AI has created a critical gap between technological innovation and responsibility frameworks. This article examines the comprehensive challenges posed by AI systems that can autonomously generate content and make decisions affecting crucial social domains. We analyze the failure of traditional accountability mechanisms in addressing AI's emergent behaviors and ``black box'' characteristics, and propose a multi-dimensional approach to responsibility allocation. The analysis covers five key areas: the primary responsibilities of technology developers throughout the AI lifecycle, the necessary paradigm shifts in legal frameworks including new concepts of algo...

The rapid expansion of edge computing and Internet of Things (IoT) ecosystems has introduced new cybersecurity challenges, particularly in decentralized, resource-constrained environments where traditional security models often fall short. This paper proposes an immune-inspired artificial intelligence framework (I3AI) that draws on core principles of biological immune systems including self-organization, local learning, and immune memory to enable adaptive, privacy-preserving defense mechanisms across distributed edge nodes. The architecture incorporates federated learning to maintain a decentralized threat intelligence network while ensuring data privacy and minimal communication overhead.... More >

This study systematically reviews the current status and recent advances in intelligent depression detection, aiming to provide insights for applying artificial intelligence in mental health. Using a systematic review approach, we analyze detection methods based on multiple data types including voice, facial expressions, body signals, and social media texts, while examining how algorithms have evolved from traditional machine learning to deep learning. Results show that AI technology has clear benefits in improving detection accuracy, reducing costs, and enabling early warning systems. Current research still faces important challenges in data collection, technical reliability, clinical use,... More >

In the medical field, efficient and accurate classification of sequential and structured data is crucially important and useful for early diagnosis and treatment. Traditional machine learning models struggle with the complexity and nonlinearity of dynamic datasets, whereas deep learning models, despite their effectiveness, require extensive resources and lack transparency. This paper proposes a novel lightweight ensemble framework integrating a parameterized SoftMax function with a non-parametric Random Forest method through a soft voting mechanism, supported by the Nonlinear AutoRegressive eXogenous (NARX) model and optimized using a forward orthogonal search and selection (FOSS) algorithm...

Topic modeling is a widely used unsupervised natural language processing (NLP) technique aimed at discovering latent themes within documents. Since traditional methods fall short in capturing contextual meaning, approaches based on large language models (LLMs)—such as BERTopic—hold the potential to generate more meaningful and diverse topics. However, systematic comparative studies of these models, especially in domains requiring high accuracy and interpretability such as healthcare, remain limited. This study compares ten different LLMs (GPT, Claude, Gemini, LLaMA, Qwen, Phi, Zephyr, DeepSeek, NVIDIA-LLaMA, Gemma) using a dataset of 9,320 medical article abstracts. Each model was tasked...
