چکیده

Boltzmann machine is a powerful tool for modeling probability distributions that govern the training data. A thermal equilibrium state typically used learning to obtain suitable distribution. The consists of calculating gradient loss function given in terms average, which most time consuming procedure. Here, we propose method implement by using Noisy Intermediate-Scale Quantum (NISQ) devices. We prepare an initial pure contains all possible computational basis states with same amplitude, and apply variational imaginary simulation. Readout after evolution approximates distribution learning. actually perform numerical simulations our scheme confirm works well scheme.

A Hybrid Algorithm based on Deep Learning and Restricted Boltzmann Machine for Car Semantic Segmentation from Unmanned Aerial Vehicles (UAVs)-based Thermal Infrared Images

Nowadays, ground vehicle monitoring (GVM) is one of the areas of application in the intelligent traffic control system using image processing methods. In this context, the use of unmanned aerial vehicles based on thermal infrared (UAV-TIR) images is one of the optimal options for GVM due to the suitable spatial resolution, cost-effective and low volume of images. The methods that have been prop...
