Neural Network for Low-Memory IoT Devices and MNIST Image Recognition Using Kernels Based on Logistic Map
share
The study presents a neural network, which uses filters based on logistic mapping (LogNNet). LogNNet has a feedforward network structure, but possesses the properties of reservoir neural networks. The input weight matrix, set by a recurrent logistic mapping, forms the kernels that transform the input space to the higher-dimensional feature space. The most effective MNIST handwritten digit recognition occurs under chaotic behavior of logistic map. An advantage of LogNNet implementation on IoT Devices is the significant savings in used memory (more than 10 times) compared to other neural networks. The presented network architecture uses an array of weights with a total memory size from 1 kB to 29 kB and achieves a classification accuracy of 80.3-96.3
