Abstract Although Deep Neural Networks (DNNs) have been widely applied in various cognitive applications, they are still very computationally intensive for resource-constrained mobile systems. In this talk, I will introduce my past research experience on optimizing DNN computing efficiency for mobile devices. First, I will introduce a neural design from the algorithm aspect, which shows better information extraction efficiency than the current neuron in DNNs; Second, I will explore the DNN inference optimization margin by showing computation redundancy from the input side; Third, we will focus on optimizing DNN models regarding specific resource constraints in mobile systems; At last, we show the system design of collaborative learning with massive mobile devices.
