A least square support vector machine algorithm for solving huge contradictory equations(求解大规模矛盾方程组的最小二乘支持向量机算法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2022
房价预测、共享单车出租数量预测、空气污染情况预测等常涉及矛盾方程组求解,对其数值求解方法研究具有重要的理论意义与应用价值。当矛盾方程组规模过大时,用传统的最小二乘法求解,不仅计算量大,而且由于误差积累使最终结果的准确性不高。鉴于此,采用机器学习中的最小二乘支持向量机(least squares support vector machine,LS-SVM)算法求解大规模矛盾方程组,并分别针对线性、非线性、单变量、多变量矛盾方程组进行了数值求解。数值结果表明,数据类型和数据量的变化对结果的影响不大 ...
