While machine learning is traditionally a resource intensive task, embedded systems, autonomous navigation and the vision of the Internet-of-Things fuel the interest in resource efficient approaches. These approaches require a carefully chosen trade-off between performance and resource consumption in terms of computation and energy. The tremendous memory and computational complexity of e.g. Convolutional Neural Networks (CNNs) prevents the deployment on resource-constrained systems.
As a result, recent research focused on CNN optimization techniques, in particular quantization, which allows weights and activations of layers to be represented with just a few bits while achieving impressive prediction performance. However, aggressive quantization techniques still fail to achieve full-precision prediction performance on state-of-the-art CNN architectures on large-scale classification tasks.
In this work we aim to use and explore (eventually complex-valued) CNNs and DNNs with reduced-precision weights and activations for image and speech classification problems. Furthermore, we are interested to explore them using alternative quantization approaches.
