Representation of the stochastic matrix sets with given properties based on autonomous automatic models
Published 2019-09-01“…This paper considers the methods of construction (presentation) of the sets of ergodic stochastic matrices using automaton models and determination of the power estimates of the generated sets. The research aimed at developing algorithms for constructing the sets of ergodic stochastic matrices with rational elements with given structures and limit vector based on the automaton probabilistic and deterministic models represented by autonomous automata, as well as at estimating the power of the obtained sets of stochastic matrices depending on the dimensions of the given automaton models. …”

Classical Simulability of Quantum Circuits with Shallow Magic Depth
Published 2025-02-01“…Surprisingly, with the addition of just one T-gate layer or merely replacing all T gates with T^{1/2}, the Pauli evaluation task reveals a sharp complexity transition from being in P to being GapP-complete. Nevertheless, when the precision requirement is relaxed to 1/poly(n) additive error, we are able to give a polynomial-time classical algorithm to compute amplitudes, Pauli observables, and sampling from log(n)-sized marginal distributions for any magic-depth-1 circuit that is decomposable into a product of diagonal gates. …”

Deep Learning-Based Multi-Floor Indoor Localization Using Smartphone IMU Sensors With 3D Location Initialization
Published 2025-01-01“…In this paper, we explain conventional IMU sensor-based PDR methods and describe the problems of PDR as well as the limitations of barometer-based floor transition detection techniques. The proposed initial 3D position estimation method detects the initial floor using a deep learning model trained on magnetic field sequences from the user’s first 10 steps, and estimates the 2D position by comparing the current magnetometer data with a pre-built magnetic field map using the k-nearest neighbors algorithm. …”

Lightweight opportunistic routing forwarding strategy based on Markov chain
Published 2017-05-01“…A lightweight opportunistic routing forwarding strategy (MOR) was proposed based on Markov chain.In the scheme,the execute process of network was divided into a plurality of equal time period,and the random encounter state of node in each time period was represented by activity degree.The state sequence of a plurality of continuous time period constitutes a discrete Markov chain.The activity degree of encounter node was estimated by Markov model to predict its state of future time period,which can enhance the accuracy of activity degree estimation.Then,the method of comprehensive evaluating forwarding utility was designed based on the activity degree of node and the average encounter interval.MOR used the utility of node for making a routing forwarding decision.Each node only maintained a state of last time period and a state transition probability matrix,and a vector recording the average encounter interval of nodes.So,the routing forwarding decision algorithm was simple and efficient,low time and space complexity.Furthermore,the method was proposed to set optimal number of the message copy based on multiple factors,which can effectively balance the utilization of network resources.Results show that compared with existing algorithms,MOR algorithm can effectively increase the delivery ratio and reduce the delivery delay,and lower routing overhead ratio.…”
