Machine learning

The language network in the brain is taxed more heavily by complicated sentences that aren’t easily recognized.

MIT researchers have used an artificial language network to decipher which types of sentences activate the brain's language processing centers most effectively. Their study reveals that sentences of higher complexity with unusual grammar or unexpected meanings engage these centers to a greater degree than straightforward sentences or nonsensical series of words. Their findings are based…

DARPA conducted trials involving an AI-controlled F-16 jet in a simulated air-to-air combat against a human opponent.

The Defense Advanced Research Projects Agency (DARPA) has disclosed the first-in-air trial of an AI-piloted jet in a simulated combat against a human-operated F-16. The AI pilot performance was demonstrated at the Air Force Test Pilot School at Edwards Air Force Base, California in September 2023 but was only recently announced. The AI system, developed…

MIT researchers employ AI to discover a potential new category of antibiotics.

MIT researchers have used a form of artificial intelligence called deep learning to identify a new classification of compounds that can effectively kill methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant bacterium accountable for over 10,000 deaths in the US each year. The researchers have demonstrated that these deep-learning-identified compounds not only have the ability to kill…

Formal Interaction Model (FIM): A mathematically driven machine learning model which articulates the mutual influence between AI systems and their users.

Machine learning is the driving force behind data-driven, adaptive, and increasingly intelligent products and platforms. Algorithms of artificial intelligence (AI) systems, such as Content Recommender Systems (CRS), intertwine with users and content creators, in turn shaping viewer preferences and the available content on these platforms. However, the current design and evaluation methodologies of these AI systems…

Scientists at Stanford University are investigating Direct Preference Optimization (DPO), opening up fresh prospects in the field of machine learning and human feedback.

Exploring the interactions between reinforcement learning (RL) and large language models (LLMs) sheds light on an exciting area of computational linguistics. These models, largely enhanced by human feedback, show remarkable prowess in understanding and generating text that mirrors human conversation. Yet, they are always evolving to capture more subtle human preferences. The main challenge lies…
