NNEF - Industry Call for Participation in a new neural network initiative

Neural network technology has seen recent explosive progress in solving pattern matching tasks in computer vision such as object recognition, face identification, image search, image to text, and is also playing a key part in enabling driver assistance and autonomous driving systems.

Convolutional Neural Networks (CNN) are computationally expensive, and so many companies are actively developing mobile and embedded processor architectures to accelerate neural net-based inferencing at high speed and low power. As a result of such rapid progress, the market for embedded neural net processing is in danger of fragmenting, creating barriers for developers seeking to configure and accelerate inferencing engines across multiple platforms.
