A Side Lobe Level Reduction Method Using Simulated Annealing Algorithm in a Uniform Arc Array
Archives of AcousticsIn general, the amplitude-weighting method for an acoustic transducer array is widely used to improve the array directivity and reject disturbances. This paper presents a method to effectively reduce the side lobe level while minimizing the main lobe ...

Improving plant-available water estimation using model averaging of national soil water models
Frontiers in Soil ScienceIntroductionMultiple operational soil water balance (SWB) models provide real-time estimates of soil moisture across Australia, yet differences in model structure and outputs introduce uncertainty for end users. Model averaging offers a potential pathway

Improved Deadbeat Algorithm‐Based Sequential Model Predictive Control Strategy for QZSI‐PMSM System
The Journal of EngineeringThe conventional model predictive control (MPC) for the quasi‐Z‐source inverter–permanent magnet synchronous motor (QZSI‐PMSM) system suffers from conflicts between the modulation coefficients of both sides and many weighting coefficients in the cost ...

Rethinking Attention Weights as Bidirectional Coefficients
Journal of Data ScienceAttention mechanism has become an almost ubiquitous model architecture in deep learning. One of its distinctive features is to compute non-negative probabilistic distribution to re-weight input representations. This work reconsiders attention weights as bidirectional coefficients instead of probabilistic measures for potential benefits in ...

A robust coefficient of determination based on implicit weighting
Applications of MathematicsIn the linear regression model, the standard coefficient of determination $R^2$ and its weighted counterpart are commonly used to assess the quality of the linear fit. However, both metrics are susceptible to the influence of outliers and heteroskedasticity within the dataset. This paper introduces a robust version of $R^2$, based on the least weighted
