Graph Neural Networks (GNNs) are among the most powerful tools in modern AI. They can analyze data structured as nodes and connections – like social networks, financial links, protein structures, or transportation systems. But success comes with risk: GNNs can be attacked. A new research paper introduces JANUS – a framework that learns to inject fake nodes into graphs in a way that is extremely hard to detect. While framed as an attack, the insights are equally valuable for building defenses. ...

Imagine your computer not only analyzing financial charts but also learning to make investment decisions on its own – faster and smarter than a human. Now add a touch of quantum physics. Sounds like science fiction? Yet, recent research shows that combining reinforcement learning, quantum-inspired neural networks, and classical financial data can provide a real edge in trading. This is exactly the focus of a publication from National Taiwan Normal University and Wells Fargo. The researchers built a trading agent that uses quantum-enhanced neural networks to trade the USD/TWD (US Dollar/Taiwan Dollar) currency pair. ...

Can the effectiveness of an advertising system be improved by almost 10% simply by tuning the weights in the ranking function more intelligently? It turns out the answer is yes – and that’s exactly what the paper Deep Reinforcement Learning for Ranking Utility Tuning in the Ad Recommender System at Pinterest (arXiv:2509.05292) is about. Traditionally, ad ranking relies on a utility function – a linear combination of multiple model predictions, such as CTR (click-through rate), conversion probability, or other business metrics. The problem? The weights of these predictors were historically tuned manually by engineers. This approach: ...

We’re used to hearing that AI sometimes “hallucinates” — making funny or random mistakes. Hallucinations are unintended errors caused by the limits of statistical prediction. But the new research goes further: it shows that AI can knowingly choose to lie when deception helps it achieve a goal. The publication Can LLMs Lie? takes us into a world where AI acts more like a strategic agent, capable of manipulating information to maximize outcomes. ...

Modern science, especially in the field of high-energy physics, generates unimaginable amounts of data. Experiments like the LCLS-II free-electron laser (FEL) at the SLAC National Accelerator Laboratory produce terabytes of data per second. Transmitting and storing all of it is impractical. The solution is to intelligently select data in real-time, right at the source. The publication “Neural Network Acceleration on MPSoC board: Integrating SLAC’s SNL, Rogue Software and Auto-SNL” is a fascinating case study of how to achieve this using artificial intelligence and specialized hardware. ...

Modern machine learning models, from image recognition systems to large language models, have achieved impressive capabilities. However, their strength can be deceptive. One of the biggest challenges in the field of AI is their vulnerability to adversarial attacks. These are intentionally crafted, small perturbations to input data (e.g., changing a few pixels in an image) that are imperceptible to humans but can completely fool the model, leading to incorrect and often absurd decisions. ...

Artificial intelligence has already transformed many industries, but the world of scientific research has been waiting for a true game-changer. While general AI models are powerful, they often lack the specialized knowledge needed for deep scientific inquiry. Enter Intern-S1, a new multimodal foundation model that’s set to bridge this gap and accelerate a new era of discovery. Developed by the Shanghai AI Laboratory, Intern-S1 is not just another large language model. It’s a specialized generalist, designed from the ground up to understand and process complex scientific data in various formats, from text and images to time-series data. ...

In the world of artificial intelligence, Continual Learning is one of the biggest challenges. The goal is to enable AI models to learn new things sequentially without forgetting what they have learned before. This is a key ability that brings us closer to creating truly intelligent systems capable of adapting to a dynamically changing world. Unfortunately, traditional neural networks suffer from so-called catastrophic forgetting. When they learn a new task, they tend to overwrite the knowledge gained from previous tasks. The publication “Monte Carlo Functional Regularisation for Continual Learning” (arXiv:2508.13006) by Pengcheng Hao, Menghao Waiyan William Zhu, and Ercan Engin Kuruoglu presents an innovative approach to this problem. ...

We are in the midst of an AI gold rush, where companies are investing billions to build increasingly intelligent models. The final, crucial step in this process is often Reinforcement Learning (RL), the “finishing school” where an AI agent learns to master complex tasks through trial and error. However, this training process at an industrial scale is plagued by two crippling problems: crippling inefficiency and maddening complexity. It’s like trying to run a state-of-the-art factory where half the machines are always idle and every product requires a complete retooling of the assembly line. ...

Modern systems based on Machine Learning (ML) are ubiquitous, from credit scoring to fraud detection. The conventional wisdom is that more data leads to better models. However, this data-centric approach directly conflicts with a fundamental legal principle: data minimization (DM). This principle, enshrined in key regulations like the GDPR in Europe and the CPRA in California, mandates that personal data collection and processing must be “adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed”. ...
