According to news reporting out of Mangalore, India, by N ewsRx editors, research stated, "Addressing real-time optimization problems beco mes increasingly challenging as their complexity continues to escalate over time . So bio-optimization algorithms (BoAs) come into the picture to solve such prob lems due to their global search capability, adaptability, versatility, paralleli sm, and robustness." Our news editors obtained a quote from the research from National Institute of T echnology Karnataka: "This article aims to perform hyperparameter tuning of mach ine learning (ML) models by integrating them with BoAs. Aiming to maximize the a ccuracy of the hybrid bio-optimized defect prediction (HBoDP) model, this resear ch paper develops four novel hybrid BoAs named the gravitational force Levy flig ht grasshopper optimization algorithm (GFLFGOA), the gravitational force Levy fl ight grasshopper optimization algorithm-sparrow search algorithm (GFLFGOA-SSA), the gravitational force grasshopper optimization algorithm-sparrow search algori thm (GFGOA-SSA), and the Levy flight grasshopper optimization algorithm-sparrow search algorithm (LFGOA-SSA). These aforementioned algorithms are proposed by in tegrating the good exploration capacity of the SSA with the faster convergence o f the LFGOA and GFGOA. The performances of the GFLFGOA, GFLFGOA-SSA, GFGOA-SSA, and LFGOA-SSA are verified by conducting two different experiments. Firstly, the experimentation was conducted on nine benchmark functions (BFs) to assess the m ean, standard deviation (SD), and convergence rate. The second experiment focuse s on boosting the accuracy of the HBoDP model through the fine-tuning of the hyp erparameters in the artificial neural network (ANN) and XGBOOST (XGB) models. To justify the effectiveness and performance of these hybrid novel algorithms, we compared them with four base algorithms, namely the grasshopper optimization alg orithm (GOA), the sparrow search algorithm (SSA), the gravitational force grassh opper optimization algorithm (GFGOA), and the Levy flight grasshopper optimizati on algorithm (LFGOA)."

According to news reporting out of Singapore, Singapore, by New sRx editors, research stated, "Machine learning-based model predictive control ( ML-MPC) has been developed to control nonlinear processes with unknown first-pri nciples models. While ML models can capture nonlinear dynamics of complex system s, the complexity of ML models leads to increased computation time for real-time implementation of ML-MPC." Financial supporters for this research include NRF-CRP Grant, MOE AcRF Tier 1 FR C Grant. Our news journalists obtained a quote from the research from the National Univer sity of Singapore, "To address this issue, in this work, we propose an explicit ML-MPC framework for nonlinear processes using multi-parametric programming. Spe cifically, a self-adaptive approximation algorithm is first developed to obtain a piecewise linear affine function that approximates the behaviors of ML models. Then, multiparametric quadratic programming (mpQP) problems are formulated to generate the solution map for states in discretized state-space. Furthermore, t o accelerate the implementation of explicit ML-MPC, a neighbor- first search alg orithm is developed."

One hundred participants with hip QCT images were selecte d from the Hong Kong part of the Osteoporotic fractures in men cohort. Radiomics features were extracted from QCT images. Filter method, Pearson correlation ana lysis, and least absolute shrinkage and selection operator method were employed for feature selection and dimension reduction. The remaining features were utili zed as inputs, and femoral strengths were calculated as the ground truth through QCT/FEA. Support vector regression was applied to develop a femoral strength pr ediction model. The influence of various numbers of input features on prediction performance was compared, and the femoral strength prediction model was establi shed. Finally, Shapley additive explanation, accumulated local effects, and part ial dependency plot methods were used to explain the model. The results indicate d that the model performed best when six radiomics features were selected. The c oefficient of determination ®, the root mean square error, the normalized root m ean square error, and the mean squared error on the testing set were 0.820, 1016 .299 N, 10.645%, and 750.827 N, respectively. Additionally, these f eatures all positively contributed to femoral strength prediction."

According to news reporting originating from Latrobe Universi ty by NewsRx correspondents, research stated, "Accurate energy consumption forec asting is crucial for reducing operational costs, achieving net-zero carbon emis sions, and ensuring sustainable buildings and cities of the future." Our news journalists obtained a quote from the research from Latrobe University : "Despite the frequent use of Artificial Intelligence (AI) algorithms for learn ing energy consumption patterns and predictions in Building Science, relying sol ely on these techniques for energy demand prediction addresses only a fraction o f the challenge. A drift in energy usage can lead to inaccuracies in these AI mo dels and subsequently to poor decision-making and interventions. While drift det ection techniques have been reported, a reliable and robust approach capable of explaining identified discrepancies with actionable insights has not been discus sed in extant literature. Hence, this paper presents an Artificial Intelligence framework for energy consumption forecasting with explainable drift detection, a imed at addressing these challenges. The proposed framework is composed of energ y embeddings, an optimized dimensional model integrated within a data warehouse, and scalable cloud implementation for effective drift detection with explainabi lity capability. The framework is empirically evaluated in the real-world settin g of a multi-campus, mixed-use tertiary education setting in Victoria, Australia ."

    Findings from LUT University in Robotics Reported (System Identification and For ce Estimation of Robotic Manipulator Using Semirecursive Multibody Formulation)

    46-47页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Research findings on Robotics are disc ussed in a new report. According to news reporting from Lappeenranta, Finland, b y NewsRx journalists, research stated, "Force estimation in multibody dynamics r elies heavily on knowing the system model with a high level of accuracy. However , in complex mechatronic systems, such as robots or mobile machinery, the values of model parameters may be only roughly estimated based on design information, such as CAD data." Funders for this research include Flanders Make, KU Leuven Mechatronic System Dy namics. The news correspondents obtained a quote from the research from LUT University, "The errors in model parameters consequently have a direct effect on force estim ation accuracy because the estimator compensates the erroneous inertia, friction , and applied forces by changing the value of estimated external force. The obje ctive of this study is to present the workflow of system identification and stat e/force estimation of an open-loop multibody structure. The system identificatio n utilizes a linear regression identification method used in robotics adapted to the multibody framework. The semirecursive multibody formulation, in particular , is studied as a formulation for both system identification and force estimatio n. The multibody state/force estimator is constructed using extended Kalman filt er. The specific aim of this paper is to demonstrate the utilization of these pe r se known modeling, identification, and estimation tools to address their curre nt lack of integration as a complete toolchain in virtual sensing of multibody s ystems. The methodology of the study is tested with both artificial and experime ntal data of St & auml;ubli TX40 robotic manipulator. In the exper imental analysis, an openly available benchmark data set was used. Artificial data were created by running an inverse dynamics analysis with inertia and frictio n parameters taken from literature. The results show that the multibody inertia and friction parameters can be accurately identified and the identified model ca n be used to produce decent estimates of external forces. The proposed multibody system identification method itself opens new opportunities in tuning the multi body models used in product development. Moreover, effective use of system ident ification together with state estimation helps to build more accurate estimators ."
