NEC Develops Deep Learning
Technology to Improve Recognition Accuracy
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.”
