"Once the team were confident the computer could identify different signs in this way, they exposed it to around 10 hours of TV footage that was both signed and subtitled. They tasked the software with learning the signs for a mixture of 210 nouns and adjectives that appeared multiple times during the footage."

"We propose a framework based on multiple instance
learning which can learn a large number of British Sign
Language signs from TV broadcasts. We achieve very
promising results even under these weak and noisy conditions
by using a state-of-the-art upper-body tracker, descriptors
of the hands that properly model the case of touching
hands, and a plentiful supply of data. A similar method
could be applied to a variety of fields where weak supervision
is available, such as learning gestures and actions."
