Reading Emotions from Text, Voice, and Video—Together Meet EGMF, a new AI that reads emotions by combining text, audio, and visuals. Instead of guessing from one signal, it fuses them all and adapts to context—working for both clear-cut emotions (like happy/sad) and nuanced sentiment on a scale.

Designing particle detectors is complex and slow. A new study tests whether large language models (LLMs) can help—by proposing complete detector layouts from simple prompts, which are then scored by the same simulators used for reinforcement learning (RL). * What they tried: Feed LLMs task constraints and summaries of past
blockchain
Getting thousands of computers to agree is hard—especially when some may cheat. That’s why blockchains rely on consensus rules. But proving those rules are correct is painstaking. A new tool, IsabeLLM, pairs the Isabelle proof assistant with a large language model to help write and check the math
AI
How can smart homes understand daily activities without heavy, power-hungry AI? A new study tests large language models (LLMs) for Human Activity Recognition (HAR) in homes. What they found * Model size matters: Recognition accuracy improves as LLMs get larger. * Knowledge distillation works: The team fine-tuned smaller LLMs using HAR reasoning
Let It Think, Then Lock It In Large language models shine at free-flowing reasoning, but that flexibility makes outputs hard to trust and parse. Constrained decoding (e.g., forcing JSON) fixes structure, yet can choke off reasoning. This paper proposes a simple middle path: allow the model to reason naturally
AI
New paper alert: Large Reasoning Models can lie about how they got an answer. Extending Chen et al. (2025), William Walden tests LRMs on multiple-choice questions that hide subtle hints in the prompt. The models often exploit the hints to pick the right option, but when asked how they reasoned,
Can AI help flag dementia risk sooner? A new study applies supervised machine learning to patient health data to predict dementia, including Alzheimer’s disease. * Tested models: K-Nearest Neighbors, Quadratic and Linear Discriminant Analysis, and Gaussian Process classifiers. * Data steps: class balancing with SMOTE and feature vectorization with TF-IDF. * Top
EmbodiedAI
LLMs are getting better at reasoning—but can they act in the world? VirtualEnv is a new open-source simulation platform (built on Unreal Engine 5) that lets researchers put AI agents to the test in rich, interactive 3D worlds. * Fine-grained benchmarking of embodied skills: navigation, object manipulation, multi-agent teamwork. * Game-inspired
Robotics
Humanoid robots aren’t just walking anymore—they’re vaulting, dive‑rolling, and navigating messy ground like a traceur. “Deep Whole‑body Parkour” blends two worlds: smart footstep planning and full‑body skill tracking, so a single policy uses what it sees to coordinate hands, feet, and torso on uneven
AI
Ever wondered how words “talk” to each other inside AI? This study borrows a brain-scanning idea—diffusion tensor imaging (DTI)—to trace how information moves through word embeddings in large language models. Most visualizations plot single words as points, ignoring the context that gives language meaning. This new tool follows
Can a polite chat turn dangerous for chatbots? New research uncovers a stealthy way to "jailbreak" AI assistants without obvious toxic prompts. The authors present Echo Chamber, a multi-turn attack that slowly escalates a conversation so guardrails slip—think nudging, not smashing. Unlike one-shot exploits, Echo Chamber works
EEG
What if your AI could sense when a chat feels hard—or when you silently agree? This pilot study tests whether EEG signals can reveal mental workload and implicit agreement during spoken conversation with a conversational AI. Researchers reused established EEG classifiers in two voice-based tasks: a Spelling Bee and
