USC serving to robots rapidly study new methods

Using only one video or textual demonstration of a task, RoboCLIP performed two to three times better than other imitation learning models.

A analysis challenge led by USC laptop science pupil Sumedh A. Sontakke needs to open the door for robots to be caregivers for growing older populations. The workforce claims the RoboCLIP algorithm, developed with assist from Professor Erdem Biyik and Professor Laurent Itti, permits robots to carry out new duties after only one demonstration.

RoboCLIP solely must see one video or textual demonstration of a process for it to carry out the duty two or 3 times higher than different imitation studying (IL) fashions, the workforce claimed.

“To me, essentially the most spectacular factor about RoboCLIP is with the ability to make our robots do one thing primarily based on just one video demonstration or one language description,” stated Biyik, a roboticist who joined USC Viterbi’s Thomas Lord Division of Laptop Science in August 2023 and leads the Studying and Interactive Robotic Autonomy Lab (Lira Lab).

The challenge began two years in the past when Sontakke realized how a lot information is required to have robots carry out fundamental family duties.

“I began desirous about family duties like opening doorways and cupboards,” Sontakke stated. “I didn’t like how a lot information I wanted to gather earlier than I might get the robotic to efficiently do the duty I cared about. I wished to keep away from that, and that’s the place this challenge got here from.”

How does RoboCLIP work?

Most IL fashions learn to full duties by trial and error. The robotic performs the duty over and over to get a reward when it lastly completes the duty. Whereas this may be efficient, it requires large quantities of time, information, and human supervision to get the robotic to efficiently carry out a brand new process.

“The massive quantity of information presently required to get a robotic to efficiently do the duty you need it to do isn’t possible in the true world, the place you need robots that may study rapidly with few demonstrations,” Sontakke stated in a launch.

RoboCLIP works in another way than typical IL fashions, because it incorporates the newest advances in generative AI and video-language fashions (VLMs). These programs are pre-trained on giant quantities of video and textual demonstrations, in keeping with Biyik.

The researchers claimed RoboCLIP performs effectively out of the field to carry out family duties, like opening and shutting drawers or cupboards.

“The important thing innovation right here is utilizing the VLM to critically ‘observe’ simulations of the digital robotic babbling round whereas attempting to carry out the duty, till in some unspecified time in the future it begins getting it proper – at that time, the VLM will acknowledge that progress and reward the digital robotic to maintain attempting on this route,” Itti stated.

In accordance with Itti, the VLM can inform it’s getting nearer to success when the textual description it creates observing the robotic comes nearer to what the consumer needs.

“This new type of closed-loop interplay may be very thrilling to me and can seemingly have many extra future functions in different domains,” Itti stated.

What’s subsequent?

Sontakke hopes that this system might sometime assist robots take care of growing older populations, or result in different functions that would assist anybody. The workforce says that future analysis will probably be obligatory earlier than the system is able to tackle the true world. 

The paper, titled RoboCLIP: One Demonstration is Sufficient to Be taught Robotic Insurance policies, was offered by Sontakke on the thirty seventh Convention on Neural Info Processing Techniques (NeurIPS), Dec. 10-16 in New Orleans.

Collaborating with Sontakke, Biyik and Itti on the RoboCLIP paper have been two USC Viterbi graduates, Sebastien M.R. Arnold, now at Google Analysis, and Karl Pertsch, now at UC Berkeley and Stanford College. Jesse Zhang, a fourth-year Ph.D. candidate in laptop sciences at USC Viterbi, additionally labored on the RoboCLIP challenge.
