Architecturing Binarized Neural Networks for Traffic Sign Recognition

Understand

Traffic signs support road safety and managing the flow of traffic, hence are an integral part of any vision system for autonomous driving.

• While the use of deep learning is well-known in traffic signs classification due to the high accuracy results obtained using convolutional neural networks (CNNs) (state of the art is 99.46\%), little is known about binarized neural networks (BNNs).
• Compared to CNNs, BNNs reduce the model size and simplify convolution operations and have shown promising results in computationally limited and energy-constrained devices which appear in the context of autonomous driving.
• This work presents a bottom-up approach for architecturing BNNs by studying characteristics of the constituent layers.
