NEC Develops Deep Learning Technology to Improve Recognition Accuracy

NEC Corporation (TSE:6701) today announced it has developed
automatic optimization technology for deep learning in order to
facilitate improvements in recognition accuracy.
In recent years, there have been tremendous advances in deep
learning, which is now contributing to image recognition, speech
recognition, and a wide range of other fields. Deep learning
enables higher levels of recognition accuracy by capitalizing on
the deeply layered structures of artificial neural networks in
order to learn from prepared data.
If systems become excessively familiar with data however, they
become unable to accurately recognize data that they have not
learned. This is known as "overtraining," and results in
degradation of recognition accuracy when dealing with data that was
not used in the learning process. To prevent overtraining,
"regularization" technology is commonly used, which regulates the
extent of learning to prevent it from reaching an excessive
degree.
"This technology predicts the progress of learning at every layer
based on the structure of an artificial neural network, and enables
regularization to be automatically configured accordingly," said
Akio Yamada, General Manager of NEC's Data Science Research
Laboratories. "This means that learning is optimized across the
entire network, making it possible to improve recognition accuracy,
such as reducing recognition errors by around 20% when compared to
conventional systems."
"This technology is expected to improve recognition accuracy for
image and speech recognition, and a whole host of other fields in
which deep learning is used," continues Yamada. "It will be able to
improve the accuracy of facial recognition and behavior analysis
for purposes that include video surveillance, for instance, or to
increase the efficiency of inspections of infrastructure, or enable
the automatic detection of system failures, accidents or
disasters."
