A Polynomial Neural network with Controllable Precision and Human-Readable Topology II: Accelerated Approach Based on Expanded Layer
share
How about converting Taylor series to a network to solve the black-box nature of Neural Networks? Controllable and readable polynomial neural network (Gang transform or CR-PNN) is the Taylor expansion in the form of network, which is about ten times more efficient than typical BPNN for forward-propagation. Additionally, we can control the approximation precision and explain the internal structure of the network; thus, it is used for prediction and system identification. However, as the network depth increases, the computational complexity increases. Here, we presented an accelerated method based on an expanded order to optimize CR-PNN. The running speed of the structure of CR-PNN II is significantly higher than CR-PNN I under preserving the properties of CR-PNN I.
