Gradient-based cuckoo search algorithm (GBCS)Condition monitoringBogie systemRailway maintenanceCondition monitoring is used as a tool for maintenance management and function as input to decision support. Thus the key parameters in preventing severe damage to railway assets can be determined by automatic...
However, for the functions whose gradient is available, the use of the gradient may improve the reliability and efficiency of the stochastic search algorithm. In particular, the quality and precision of solutions obtained with gradient-based optimization methods outperform those obtained with traditional...
An extended stochastic gradient algorithm is presented based on the gradient search. By means of the multi-innovation identification theory, the resulting multi-innovation extended stochastic gradient algorithm can track time-varying parameters. The performance of the proposed algorithms is demonstrated by ...

This ensures the first proposed solution is directed by the search direction of SPSA and the subsequent iterations are based on the Adam update rule. As opposed to SD-SPSA, this algorithm does not require a backtracking line-search, as the results (not presented) showed no improvements. The ...
This paper provides a gradient search algorithm for finding the maximal visible area polygon (VAP) viewed by an interior point in a simple polygon P. The algorithm is based on a natural partition of P into convex sets, such that each element of the partition is associated with a unique ...
But I am very curious if there is anything to the combination of this early bootstrapping method via an evolutionary algorithm and the extension of GFlowNets to maybe a space where the actions are less well-defined. 是的,有很多重叠的地方。另一个让我印象深刻的是进化算法,我认为你以前也提到...
GBO is a novel metaheuristic optimization algorithm. The GBO, inspired by the gradient-based Newton’s method, uses two main operators: gradient search rule (GSR) and local escaping operator (LEO) and a set of vectors to explore the search space. The GSR employs the gradient-based method to...
This can be done with any of a variety of line search algorithms. One might also simply guess which gives Evaluating the objective function at this value, yields The decrease from to the next step's value of 第一次迭代不同gama值的详细过程 标签: algorithm , gradient descent 0 0 «...
start is the point where the algorithm starts its search, given as a sequence (tuple, list, NumPy array, and so on) or scalar (in the case of a one-dimensional problem). learn_rate is the learning rate that controls the magnitude of the vector update. n_iter is the number of iterati...
