A novel method enables AI chatbots to engage in conversation throughout the day without experiencing any shutdowns.

Researchers from the Massachusetts Institute of Technology (MIT) and partner organizations have developed a solution to address a key issue limiting the effectiveness of AI chatbots. Large language machine-learning models, such as ChatGPT, often crash or slow down during extended rounds of dialogue with humans. The study identified the cause of this problem as the…

This small, secure identification label has the capacity to validate nearly anything.

A group of researchers from the Massachusetts Institute of Technology (MIT) have developed a revolutionary anti-tampering ID tag. Notably smaller and significantly less expensive than traditional radio frequency identification (RFID) tags, this evolution could revolutionize the way technology authenticates the legitimacy of a product. But how does it secure itself from the common issue of…

This compact, secure identification label has the capacity to verify nearly everything.

A team of MIT researchers has created a cryptographic ID tag that boasts several advantages over existing technologies - spurring hope it will revolutionize supply chain verification. The tag is several times smaller, much cheaper, and offers better security than the radio frequency identification (RFID) tags currently used for product verification. The new tag uses…

The new system pinpoints medications that should not be combined.

Researchers from MIT, Brigham and Women’s Hospital, and Duke University have developed a system using tissue models and machine-learning algorithms to identify how different drugs navigate through the lining of the digestive tract, which could have significant implications for the world of medicine. Orally-taken drugs often rely on transporter proteins within the digestive tract's cells to…

A fresh method allows AI chatbots to communicate continuously without breaking down.

Researchers from MIT and other institutions have developed a solution to maintain continuous human-AI interactions without the chatbot crashing or slowing down. The solution, known as StreamingLLM, involves tweaking the key-value cache (like a conversation memory) that forms the heart of many large language models. Under the conventional setup, the cache, when filled beyond its…

This small, secure ID label is capable of verifying virtually anything.

A team of researchers from MIT has developed an innovative antitampering cryptographic ID tag, which is smaller, cheaper, and more secure than traditional radio frequency identification (RFID) tags. Traditional RFIDs can be detached from a genuine item and reattached on counterfeit products, compromising the authenticity of the item. As a solution, the MIT team creates…

The latest model pinpoints medications that should not be combined.

American researchers at MIT, Brigham and Women’s Hospital, and Duke University have designed an innovative approach to identifying the transporters used by different drugs that are taken orally. The strategy involves the use of both tissue models and machine-learning algorithms, and has already revealed that a commonly prescribed antibiotic and a blood thinner can interfere…

A novel approach allows AI chatbots to engage in conversation throughout the day without experiencing a system failure.

Large language AI models are notorious for crashing or slowing down during lengthy human-AI dialogues, posing a major barrier to the effective use of chatbots in many applications. Now, a team of researchers from MIT and other institutions propose a novel solution - by modifying the key-value cache, or the 'conversation memory', they improved the…

This small, secure identification label can verify nearly everything.

MIT researchers have developed a new tiny cryptographic ID tag with revolutionary terahertz technology, making it smaller, cheaper, and more secure than traditional radio frequency tags (RFIDs). The latter are often attached to products to verify authenticity but can easily be compromised by counterfeiters who remove and reattach them to fake products. To combat this,…

A novel method allows AI chatbots to engage in conversation continuously without breaking down.

MIT researchers have discovered a fault in the design of language machine-learning models that can cause AI chatbots' performance to drastically deteriorate during lengthy conversations. Essentially, when data stored in a chatbot's "memory" (known as the key-value cache) exceeds its capacity, the earliest data is removed, sometimes causing the chatbot to malfunction or slow down.…

This small, secure identification label can verify almost anything.

Researchers at MIT have developed a cryptographic ID tag that is significantly smaller, cheaper, and more secure than traditional radio frequency identification (RFID) tags. The new tag is based on the use of terahertz waves which are smaller and have much higher frequencies than radio waves. The innovation overcomes a major security flaw common with…
