Nvidia Analysis announced today that it has developed a brand new AI agent, referred to as Eureka, that’s powered by OpenAI’s GPT-4 and might autonomously train robots complicated expertise.
In a blog post, the corporate stated Eureka, which autonomously writes reward algorithms, has, for the primary time, skilled a robotic hand to carry out speedy pen-spinning methods in addition to a human can. Eureka has additionally taught robots to open drawers and cupboards, toss and catch balls, and manipulate scissors, amongst almost 30 duties.
“Reinforcement studying has enabled spectacular wins over the past decade, but many challenges nonetheless exist, akin to reward design, which stays a trial-and-error course of,” Anima Anandkumar, senior director of AI analysis at Nvidia and an writer of the Eureka paper, stated within the weblog submit. “Eureka is a primary step towards creating new algorithms that combine generative and reinforcement studying strategies to unravel arduous duties.”
Nvidia Analysis additionally printed the Eureka library of AI algorithms for individuals to experiment with them utilizing Nvidia Isaac Health club, a physics simulation reference utility for reinforcement studying analysis. Isaac Health club is constructed on Nvidia Omniverse, a improvement platform for constructing 3D instruments and purposes based mostly on the OpenUSD framework.
Work builds on earlier Nvidia work on AI brokers
Hype over AI agents has been swirling for months, together with with the rise of autonomous AI brokers like Auto-GPT, BabyAGI and AgentGPT again in April.
The present Nvidia Analysis work builds on earlier efforts together with the current Voyager, an AI agent constructed with GPT-4 that may autonomously play Minecraft. In a New York Times article this week on efforts to remodel chatbots into on-line brokers, Jeff Clune, a pc science professor on the College of British Columbia who was beforehand an OpenAI researcher, stated that “this can be a enormous business alternative, doubtlessly trillions of {dollars},” whereas including that “this has an enormous upside — and large penalties — for society.”
Outperforms knowledgeable human-engineered rewards
In a brand new analysis paper titled “Eureka: Human-level reward design by way of coding giant language fashions,” the authors stated that Eureka “exploits the outstanding zero-shot era, code-writing, and in-context enchancment capabilities of state-of-the-art LLMs, akin to GPT-4, to carry out evolutionary optimization over reward code.”
The ensuing rewards, they stated, can be utilized to amass complicated expertise by reinforcement studying. “With none task-specific prompting or pre-defined reward templates, Eureka generates reward capabilities that outperform knowledgeable human-engineered rewards. In a various suite of 29 open-source RL environments that embody 10 distinct robotic morphologies, Eureka outperforms human consultants on 83% of the duties, resulting in a mean normalized enchancment of 52%.”
“Eureka is a singular mixture of huge language fashions and Nvidia’s GPU-accelerated simulation applied sciences,” stated Jim Fan, senior analysis scientist at NVIDIA, who’s one of many challenge’s contributors, within the weblog submit. “We imagine that Eureka will allow dexterous robotic management and supply a brand new technique to produce bodily lifelike animations for artists.”
