Prediction of Meander Delay System Parameters for Internet-of-Things Devices Using Pareto-Optimal Artificial Neural Network and Multiple Linear Regression

Abstract

Meander structures are highly relevant in the Internet-of-Things (IoT) communication systems, their miniaturization remains as one of the key design issues. Meander structures allow to decrease the size of the IoT device, while maintaining the same operating parameters of the IoT device. Meander structures can also work as the delay systems, which can be used for the delay and synchronization of signals in IoT devices. The design procedure of the meander delay systems is time-consuming and cumbersome because of the complexity of the numerical and analytical methods employed during the design process. New methods, which will accelerate the synthesis procedure of the meander delay systems, should be investigated. This is especially relevant when the procedure of synthesis must be repeated many times until the appropriate configuration of the IoT device is found. We present the procedure of synthesis of the meander delay system using the Pareto-optimal multilayer perceptron network and multiple linear regression model with the M5 descriptor. The prediction results are compared with results, which were obtained using the commercial Sonnet software package and with the results of physical experiment. The difference between the experimentally achieved and predicted results did not exceed 1.53 %. Moreover, the prediction of parameters of the meander delay system allowed to speed up the procedure of synthesis multiple times from hours to only 2.3 s.INDEX TERMS Antenna arrays, antenna measurements, artificial neural networks, Internet of Things.

Neural network hyperparameter optimization for prediction of real estate prices in Helsinki

“…Due to it, we consider the hyper-parameter tuning as the essential task of this research and the main goal of it is to improve the baseline approach (with the initial ANN architecture and initial hyper-parameter values chosen by the human expert according to the theoretical insights) by the significant margin. The examples of methods used for optimizing ANN hyper-parameters include various nature-inspired heuristics such as monarch butterfly optimization , swarm intelligence , Bayesian optimization (Cho et al, 2020), multi-threaded training (Połap et al, 2018), evolutionary optimization (Cui & Bai, 2019), genetic algorithm (Han et al, 2020), harmony search algorithm (Kim, Geem & Han, 2020), simulated annealing (Lima, Ferreira Junior & Oliveira, 2020), Pareto optimization (Plonis et al, 2020), gradient descent optimization of a directed acyclic graph (Zhang et al, 2020) and others.…”

Detection of sitting posture using hierarchical image composition and deep learning

“…Algorithm then tries to reconstruct intermediate frame for retrieval and analysis of frame semantics, which are then used for stack validity status verification. Assuming the condition, analysis starts in the recurrent layers of our modified MobileNet v2 architecture, with Pareto-Optimal berparameter optimization ( Plonis et al, 2020 ). The model then assigns prediction labels and algorithm further tries to improve the quality by firing smart semantic prediction analyzer, checking not only the output value but probable output status for a combined confidence level of <40%, as an improved determinator for further frame semantic analysis.…”

Smart Home Battery for the Multi-Objective Power Scheduling Problem in a Smart Home Using Grey Wolf Optimizer

“…The MOP is called unconstrained MOP if and only if d and p are equal to 0. Two main methods, namely, Pareto optimality and non-Pareto methods (scalarization methods), have been proposed to solve the MOP [57][58][59]. The idea of Pareto optimality is proposed to solve MOPs using non-dominated ranking and selection to move a population toward the Pareto front.…”
