Artificial Intelligence

Scientists improve sideline sight in AI prototypes.

MIT researchers are replicating peripheral vision—a human's ability to detect objects outside their direct line of sight—in AI systems, which could enable these machines to more effectively identify imminent dangers or predict human behavior. By equipping machine learning models with an extensive image dataset to imitate peripheral vision, the team found these models were better…

Three Inquiries: Essential Information on Audio Deepfakes You Should Know

Recently, an AI-generated robocall mimicking Joe Biden urged New Hampshire residents not to vote. Meanwhile, "spear-phishers" – phishing campaigns targeting specific people or groups – are using audio deepfakes to extract money. However, less attention has been paid to how audio deepfakes could positively impact society. Postdoctoral fellow Nauman Dawalatabad does just that in a…

Galileo Unveils Luna: A Comprehensive Evaluation Framework for Detecting Language Model Inconsistencies with Outstanding Precision and Economy

The Galileo Luna is a transformative tool in the evaluation of language model processes, specifically addressing the prevalence of hallucinations in large language models (LLMs). Hallucinations refer to situations where models generate information that isn’t specific to a retrieved context, a significant challenge when deploying language models in industry applications. Galileo Luna combats this issue…

ObjectiveBot: An AI Structure Aiming to Improve Skills of an LLM-based Agent for Accomplishing Superior Objectives.

Large language models (LLMs), such as those used in AI, can creatively solve complex tasks in ever-changing environments without the need for task-specific training. However, achieving broad, high-level goals with these models remain a challenge due to the objectives' ambiguous nature and delayed rewards. Frequently retraining models to fit new goals and tasks is also…

An AI paper from China suggests a new method based on dReLU sparsification that enhances the model’s sparsity up to 90% without compromising its performance. This innovative approach yields a two to five times acceleration during inference.

Large Language Models (LLMs) like Mistral, Gemma, and Llama have significantly contributed to advancements in Natural Language Processing (NLP), but their dense models make them computationally heavy and expensive. As they utilize every parameter during inference, this intensity makes creating affordable, widespread AI challenging. Conditional computation is seen as an efficiency-enhancing solution, activating specific model parameters…

Scientists from Stanford university and Duolingo have illustrated effective methods for achieving a specified proficiency level using proprietary models like GPT4 and open-source methods.

A team from Stanford and Duolingo has proposed a new way to manage the proficiency level in texts generated by large language models (LLMs), overcoming limitations in current methods. The Common European Framework of Reference for Languages (CEFR)-aligned language model (CALM) combines techniques of finetuning and proximal policy optimization (PPO) for aligning the proficiency levels…

Scientists improve sideline viewing capabilities in AI systems.

Peripheral vision, the ability to see objects outside of our direct line of sight, has been simulated by researchers at MIT to be used with AI technology. Unlike human vision, AI lacks the capability to perceive peripherally. Enhancing AI with this ability could greatly enhance its proactivity in identifying threats, and could even predict if…
