In the research of the algorithms and theory of temporal difference learning, a new class of multi-step learning prediction algorithms based on linear function approximators and recursive least squares methods is proposed, which are called the rls-td ( t ) learning algorithm . the convergence with probability one of the rls-td ( t ) algorithm is proved for ergodic markov chains, and the conditions for convergence are analyzed 在时域差值学习(temporaldifferencelearning)学习算法和理论方面,首次提出了一种基于线性值函数逼近的多步递推最小二乘td()(rls-td())学习算法,并分析和证明了该算法在求解遍历markov链学习预测问题中的收敛条件和一致收敛性。
Radial basis function ( rbf ) neural networks, which can be used as non-linear classifiers, have been applied extensively in pattern classification because of their salient features in being universal approximators, possing the best approximation property and the fast learning speed and having more compact topology than other neural networks 径向基(radialbasisfunction,rbf)神经网络分类器,作为非线性分类器,具有全局函数逼近、函数拟合度好、收敛速度快、网络结构紧凑等优点,被广泛运用于模式识别问题中。
Furthermore, it is verified by these sufficient conditions that the fuzzy controllers constructed by 29 fuzzy implication operators are universal approximators when all inference rules are connected by " u ", and the fuzzy controllers formed by 40 fuzzy implication operators are universal approximators when all inference rules are connected by " " 在此基础上给出了模糊控制器具有泛逼近性的若干充分条件,进而,由这些充分条件验证了当规则取并时有29个模糊蕴涵算子构成的模糊控制器具有函数的泛逼近性;当规则取交时有40个模糊蕴涵算子构成的模糊控制器具有函数的泛逼近性。
