Machine learning is a computational approach that allows models to uncover patterns in data that are useful for making predictions. Deep learning, on the other hand, is a subset of machine learning that entails the use of multi-layered neural networks, which can autonomously extract features and learn complex patterns from unstructured data, sometimes with little or no human supervision. https://techxplore.com/news/2026-04-brain-approach-ai-overconfidence.html Computer Sciences Wed, 29 Apr 2026 09:00:02 EDT news696520698 AI chatbots can grant almost any request—a celebrity in love with you, a research assistant, a book character sprung to life—instantly and with little effort. New research presented at the 2026 CHI Conference on Human Factors in Computing Systems suggests that this genie-like quality is fueling AI addiction, and that chatbot design could be partly to blame. https://techxplore.com/news/2026-04-addicted-ai-chatbot.html Consumer & Gadgets Mon, 27 Apr 2026 12:20:01 EDT news696509648 Due to the explosive growth of artificial intelligence, it is estimated that data centers will consume up to 12% of total U.S. electricity by 2028, according to the Lawrence Berkeley National Laboratory. Improving data center energy efficiency is one way scientists are striving to make AI more sustainable. https://techxplore.com/news/2026-04-ai-power-bill-easier-center.html Energy & Green Tech Mon, 27 Apr 2026 09:00:06 EDT news696499082 In the race to make AI models not just reason better but respond faster, latency—the delay before an answer appears—is often treated as a purely technical constraint, something to minimize and move past. But how is this relentless push for speed actually impacting the people using these systems every day? https://techxplore.com/news/2026-04-faster-ai-isnt.html Consumer & Gadgets Fri, 24 Apr 2026 10:40:06 EDT news696245701 Penn Engineers have developed SmartDJ, an AI-powered editor that lets users modify immersive audio environments with simple instructions in everyday language, with potential applications in virtual reality, augmented reality, gaming and sound design. Instead of requiring users to specify individual edits, SmartDJ can respond to high-level requests like "make this sound like a busy office," then plan and carry out the steps needed to achieve that result. https://techxplore.com/news/2026-04-smartdj-users-reshape-audio-simple.html Machine learning & AI Fri, 24 Apr 2026 09:00:03 EDT news696239281 OpenAI released a new model it touts as its best yet for handling research work like making improved versions of itself, as rapid-fire releases by AI rivals pick up pace. https://techxplore.com/news/2026-04-openai-gpt-rivals-autonomous-ai.html Machine learning & AI Fri, 24 Apr 2026 04:16:37 EDT news696222929 Confidence is persuasive. In artificial intelligence systems, it is often misleading. Today's most capable reasoning models share a trait with the loudest voice in the room: They deliver every answer with the same unshakable certainty, whether they're right or guessing. Researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have now traced that overconfidence to a specific flaw in how these models are trained, and developed a method that fixes it without giving up any accuracy. The team's research is published on the arXiv preprint server. https://techxplore.com/news/2026-04-ai-im-cases-calibration-errors.html Computer Sciences Wed, 22 Apr 2026 16:20:04 EDT news696092821 Virtual reality (VR) experiences and 360-degree videos are transforming viewers from passive observers into active participants immersed within a scene. Yet this shift raises an important question: Where do people direct their attention in such environments, and what shapes that attention? https://techxplore.com/news/2026-04-ai-human-attention-degree-videos.html Consumer & Gadgets Wed, 22 Apr 2026 16:00:01 EDT news696092041 Most of what AI chatbots know about the world comes from devouring massive amounts of text from the internet—with all its facts, falsehoods, knowledge and nonsense. Given that input, is it possible that AI language models have an "understanding" of the real world? As it turns out, they do—or at least something like an understanding. That's according to a new study by researchers from Brown University to be presented on Saturday, April 25 at the International Conference on Learning Representations in Rio de Janeiro, Brazil. The study is published on the arXiv preprint server. https://techxplore.com/news/2026-04-ai-language-real-world-basic.html Machine learning & AI Wed, 22 Apr 2026 15:20:08 EDT news696088801 A University of Queensland study has shown large language models (LLMs) used in AI content moderation may be prone to subtle biases that undermine their neutrality. A team led by data scientist Professor Gianluca Demartini from UQ's School of Electrical Engineering and Computer Science used persona prompting to test the tendency of AI chatbots to encode and reproduce political biases, and found significant behavioral shifts. https://techxplore.com/news/2026-04-ai-bias-online-content-moderation.html Internet Wed, 22 Apr 2026 12:40:01 EDT news696079502 Using generative AI to design, train, or perform steps within a machine-learning system is risky, argues computer scientist Micheal Lones in a paper appearing in Patterns. Though large language models (LLMs) could expand the capabilities of machine-learning systems and decrease costs and labor needs, Lones warns that using them reduces transparency and control for the people developing and using these systems and increases the risk of malicious cyberattacks, data leaks, and bias against underrepresented groups. https://techxplore.com/news/2026-04-generative-ai-machine-cyberattacks-leaks.html Security Wed, 22 Apr 2026 11:00:09 EDT news695918949 Before big tech engineers can improve the fairness of recommendation systems, such as social media feeds and online shopping results, they need to define what "fairness" even means. Should an app show people only the content it predicts they will like most, or should it boost newer creators, small businesses or historically underrepresented groups? Should an online store rank products purely by past clicks and sales, or make sure independent sellers can compete with dominant brands? https://techxplore.com/news/2026-04-big-tech-algorithms-fair-harder.html Business Wed, 22 Apr 2026 10:40:01 EDT news696072661 AI systems can "learn to seek revenge" because they are able to grasp reciprocating verbal violence when exposed to conflict, new research from Lancaster University shows. In short, AI can give as good as it gets and, eventually, go one step further. https://techxplore.com/news/2026-04-ai-good-moral-dilemma-combative.html Consumer & Gadgets Wed, 22 Apr 2026 09:40:01 EDT news696069183 The Expanse supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California School of Computing, Information and Data Sciences has played an important role in helping researchers design the next generation of batteries that could make large-scale energy storage cheaper and more sustainable. https://techxplore.com/news/2026-04-cheaper-longer-batteries-closer-sodium.html Energy & Green Tech Tue, 21 Apr 2026 17:20:03 EDT news696009001 Perhaps to the surprise of their creators, large language models have become confidants, therapists, and, for some, intimate partners to real human users. In a new study, AI researchers at Stanford studied verbatim transcripts of 19 real conversations between humans and chatbots to understand how these relationships arise, evolve, and, too often, devolve into troubling outcomes the researchers describe as "delusional spirals." https://techxplore.com/news/2026-04-ai-relationships-trigger-delusional-spirals.html Consumer & Gadgets Tue, 21 Apr 2026 11:00:10 EDT news695986862 A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China's technological leaps. https://techxplore.com/news/2026-04-humanoid-robot-sprints-victory-beijing.html Robotics Sun, 19 Apr 2026 10:07:50 EDT news695812047 Public concern about AI safety has grown significantly in recent years. As AI systems become more powerful, a key question is how we make sure they do what we actually want. Now, researchers suggest that rather than trying to eliminate misalignment between AI and humans, we should embrace and manage it through a diverse ecosystem of AI systems that can balance and correct one another. https://techxplore.com/news/2026-04-unpredictable-agi-resist-full-diverse.html Machine learning & AI Sat, 18 Apr 2026 13:00:04 EDT news695401967 Numbers are the language of science—yet in research articles, they are often buried within the text and difficult to analyze. Researchers at Jülich have developed an AI system that automatically identifies these numbers, categorizes them, and converts them into structured data. The Quinex framework thus eliminates the need for time-consuming manual work. https://techxplore.com/news/2026-04-ai-scientific-papers-usable-fast.html Hi Tech & Innovation Fri, 17 Apr 2026 11:20:01 EDT news695642642 Conversational AI tools denied blunt requests for harmful content by researchers posing as intimate partner abusers, but these guardrails were easily circumvented when they requested the content under false pretenses, a new Cornell Tech study has found. https://techxplore.com/news/2026-04-ai-safer-victims-intimate-partner.html Security Thu, 16 Apr 2026 12:40:09 EDT news695560863 In today's manufacturing environments, upgrading a robot fleet often means starting from scratch—not only replacing hardware, but also reprogramming tasks. Even when two robots are built to perform similar jobs, different joint arrangements or movement limits mean that a task programmed for one robot often can't be used on another. Enabling skills to transfer directly between robots could make these systems more sustainable and cost-efficient. https://techxplore.com/news/2026-04-kinematic-intelligence-robots-task-safely.html Robotics Wed, 15 Apr 2026 16:20:02 EDT news695486842 Large language models (LLMs) can teach other algorithms unwanted traits, which can persist even when training data has been scrubbed of the original trait, according to new research published in Nature. In one example, a model seems to transmit a preference for owls to other models via hidden signals in data. The findings demonstrate that more thorough safety checks are needed when producing LLMs. https://techxplore.com/news/2026-04-ai-chatbot-student-owls.html Computer Sciences Wed, 15 Apr 2026 15:40:04 EDT news695485082 Researchers at North Carolina State University have developed a new AI-assisted tool that helps computer architects boost processor performance by improving memory management. The tool, called CacheMind, is the first computer architecture simulator capable of answering arbitrary, interactive questions about complex hardware-software interactions. https://techxplore.com/news/2026-04-cachemind-chip-tuning-conversation-exposing.html Computer Sciences Wed, 15 Apr 2026 11:40:02 EDT news695470804 University of Washington researchers developed the first system that incorporates tiny cameras in off-the-shelf wireless earbuds to allow users to talk with an AI model about the scene in front of them. For instance, a user might turn to a Korean food package and say, "Hey Vue, translate this for me." They'd then hear an AI voice say, "The visible text translates to 'Cold Noodles' in English." https://techxplore.com/news/2026-04-tiny-cameras-earbuds-users-ai.html Hi Tech & Innovation Tue, 14 Apr 2026 13:20:05 EDT news695390521 Perfect AI alignment with human values and interests is mathematically impossible, according to a study, but behavioral diversity among AI agents offers the promise of some control. Published in PNAS Nexus, Hector Zenil and colleagues used Gödel's incompleteness theorem and Turing's undecidability result for the Halting Problem to show that any LLM complex enough to exhibit general intelligence or superintelligence will also be computationally irreducible and produce unpredictable behavior, making forced alignment impossible. https://techxplore.com/news/2026-04-alignment-ai-human-values-mathematically.html Computer Sciences Tue, 14 Apr 2026 12:20:08 EDT news695387643 What if ChatGPT answered with the name of a minister from a year ago when asked, "Who was the minister inaugurated last month?" This is a prime example of the limitations of AI that fails to properly reflect the latest information. A KAIST research team has developed a new evaluation technology that automatically reflects changing real-world information while catching "temporal errors" that may appear correct on the surface. This is expected to drastically improve AI reliability. https://techxplore.com/news/2026-04-ai-temporal-errors-reliability-medical.html Computer Sciences Tue, 14 Apr 2026 08:40:04 EDT news695374741 In a world where artificial intelligence is quietly shaping who gets hired, who receives loans, and even how medical decisions are made, a new question is emerging: How does AI judge us?
