The project
aims to create a Robot Brain computer system of large-scale able to learn from
the available resources on the internet. The program is currently downloading
and processing 1 billion images, 120,000 YouTube videos, 100 million documents
of the "How To", and appliance manuals. The information is being
translated into an easily accessible format for robots of various kinds, which
can access it when needed. "Our laptops and cell phones have access to all
the information we want. If a robot encounters a situation that has not seen
before, then he may consult the Robotic Brain in the cloud," said Ashutosh
Saxena, Cornell University, USA. The primary objective of the robotic brain is
that it acquires "understanding" of the information collected.
To serve as
helpers in our homes, offices and factories, robots assistants will have to
understand how the world works and how human beings around you behave. Researchers
in robotics have been trying to teach them a thing at a time: how to open a
door, like pouring drink into a glass, how to save the dishes and not interrupt
when two people in a conversation. The idea of the project is Brain Robot do it
all at once. The system employs what computer scientists call "deep
learning structured", where information is stored at various levels of
abstraction. A chair is a class member of the chairs, while on another level,
the chairs are mobile. The Brain Robot already know that chairs are something
that humans can sit, but that a human being can also sit on a stool or on the
lawn.
The
computer brain of a robot stores what he learned in a format that
mathematicians call a Markov model, which can be represented graphically as a
set of points connected by lines (formally called nodes and edges). Nodes can
represent objects, actions, or parts of an image, and each is assigned a
probability - how you can vary the information and it still remain correct. In
the search for knowledge, the brain of a robot makes its own chain of
associations, and search the knowledge base for information matching these
limits. As a human student, the Brain Robot teachers have, thanks to the
Community aid. The site will show things that the brain has learned, and
visitors can make additions and corrections.
