Neural Network for Low-Memory IoT Devices and MNIST Image Recognition Using Kernels Based on Logistic Map
Andrei Velichko
This 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…
Electrical switching and oscillations in vanadium dioxide
Alexander Pergament, Andrei Velichko, Maksim Belyaev +1
We have studied electrical switching with S-shaped I-V characteristics in two-terminal MOM devices based on vanadium dioxide thin films. The switching effect is associated with the…
Switching dynamics of single and coupled VO2-based oscillators as elements of neural networks
Andrei Velichko, Maksim Belyaev, Vadim Putrolaynen +2
In the present paper, we report on the switching dynamics of both single and coupled VO2-based oscillators, with resistive and capacitive coupling, and explore the capability of th…
Thermal coupling and effect of subharmonic synchronization in a system of two VO2 based oscillators
Andrei Velichko, Maksim Belyaev, Vadim Putrolaynen +2
We explore a prototype of an oscillatory neural network (ONN) based on vanadium dioxide switching devices. The model system under study represents two oscillators based on thermall…
Oscillator Circuit for Spike Neural Network with Sigmoid Like Activation Function and Firing Rate Coding
Andrei Velichko, Petr Boriskov
The study presents an oscillator circuit for a spike neural network with the possibility of firing rate coding and sigmoid-like activation function. The circuit contains a switchin…
Switch Elements with S-Shaped Current-Voltage Characteristic in Models of Neural Oscillators
Petr Boriskov, Andrei Velichko
In this paper, we present circuit solutions based on a switch element with the S-type I-V characteristic implemented using the classic FitzHugh-Nagumo and FitzHugh-Rinzel models. U…
