采用蚁群算法对BP神经网络进行优化

1. 基本思想核心目标：使用蚁群算法来优化BP神经网络的权重和偏置，克服传统BP算法容易陷入局部极小值、收敛速度慢、对初始权重敏感等问题。类比关系：蚂蚁 → 神经网络的一组权重配置（一个解）路径 → 具体的权重值信息素 → 优秀权重配置的"经验"食物源 → 最优的权重配置（误差最小ÿ...

慢SQL的模板化算法优化

变更背景当前慢SQL链路会对每条SQL进行SQL模板化处理，即对原始SQL去除变量参数后得到SQL模板，再对SQL模板进行加密获得SQLHASH。例如，原始SQL为select name, age, score from study where age > 20 and score > 10时：SQ...

在做实验中，论文需要PSO（粒子集群算法），对BP神经网络的权值跟阈值进行优化，讲解一下？

题目是：利用PSO（粒子集群算法）对BP神经网络进行优化，个人在学习中发现PSO只是在固定函数中求解他的最优解。但是神经网络的阈值跟权值都是通过PSO取得的，试问如何。神经网络的网络训练，到底干什么用了？
