常用的方法是穷尽网格搜索(Exhaustive Grid Search)和随机参数优化(Randomized Parameter Optimization)模型超参数。 顾名思义穷尽网格搜索即将所有需要选择的超参数进行组合,并将每一种组合都用于评估,优点是可以为每种参数组合测试性能;缺点是浪费计算资源,消耗时较长,在使用深度学习模型训练大规模数据集时,可能并不适用...
梯度下降算是网络优化(Optimization)的一个方法 目标:让真实值和实际值的误差尽可能小 方法:不断调整梯度 梯度躺平的点一般不止一个,但是即便是一个局部最优,也可以出色地完成任务 3. 神经网络的黑盒处理 相当于将输入一次次转换成代表特征 4. Numpy和pytorch对比 numpy array 和 torch tensor 5. 激励函数 解决...
class AdamW(Optimizer): r"""Implements AdamW algorithm. The original Adam algorithm was proposed in `Adam: A Method for Stochastic Optimization`_. The AdamW variant was proposed in `Decoupled Weight Decay Regularization`_. Arguments: params (iterable): iterable of parameters to optimize or dicts ...
The advent of deep learning has changed the landscape of artificial intelligence. This shift has improved many areas, including image analysis, natural language understanding, customized recommendations, and self-driving technology. A key contributor to these developments is the suite of libraries and fr...
