Intel Drives Continual Learning for Robots with
Neuromorphic Computing

Neuromorphic research chip Loihi demonstrates real-time
learning with 175x lower energy.
Neuromorphic Computing Helps Robots Keep Learning: In
a simulated setup, a robot actively senses objects by
moving its eyes (event-based camera or dynamic vision
sensor), generating "miscrosaccades." The events
collected are used to drive a spiking neural network on
the Loihi chip. If the object or the view is new, its
SNN representation is learned or updated. If the object
is known, it is recognized by the network and respective
feedback is given to the user.
Intel Labs, in collaboration with the Italian Institute
of Technology and the Technical University of Munich,
has introduced a new approach to neural network-based
object learning. It specifically targets future
applications like robotic assistants that interact with
unconstrained environments, including in logistics,
healthcare or elderly care. This research is a crucial
step in improving the capabilities of future assistive
or manufacturing robots. It uses neuromorphic computing
through new interactive online object learning methods
to enable robots to learn new objects after deployment.
Using these new models, Intel and its collaborators
successfully demonstrated continual interactive learning
on Intel’s neuromorphic research chip, Loihi, measuring
up to 175x lower energy to learn a new object instance
with similar or better speed and accuracy compared to
conventional methods running on a central processing
unit (CPU). To accomplish this, researchers implemented
a spiking neural network architecture on Loihi that
localized learning to a single layer of plastic synapses
and accounted for different object views by recruiting
new neurons on demand. This enabled the learning process
to unfold autonomously while interacting with the user.
The
research was published in the paper “Interactive
continual learning for robots: a neuromorphic approach,”
which was named “Best Paper” at this year’s
International Conference on Neuromorphic Systems (ICONS)
hosted by Oak Ridge National Laboratory.
“When a human learns a new object, they take a look,
turn it around, ask what it is, and then they’re able to
recognize it again in all kinds of settings and
conditions instantaneously,” said Yulia Sandamirskaya,
robotics research lead in Intel’s neuromorphic computing
lab and senior author of the paper. “Our goal is to
apply similar capabilities to future robots that work in
interactive settings, enabling them to adapt to the
unforeseen and work more naturally alongside humans. Our
results with Loihi reinforce the value of neuromorphic
computing for the future of robotics.”
