L1Decay

    L1Decay实现L1权重衰减正则化，用于模型训练，使得权重矩阵稀疏。

    具体实现中，L1权重衰减正则化的损失函数计算如下：

    参数：

    • coeff (float) – L1正则化系数，默认值为0.0。

    代码示例2

    1. # Example2: set Regularizer in parameters
    2. # Set L1 regularization in parameters.
    3. # Global regularizer does not take effect on my_conv2d for this case.
    4. from paddle import ParamAttr
    5. from paddle.regularizer import L2Decay
    7. my_conv2d = Conv2D(
    8.                 out_channels=10,
    9.                 kernel_size=1,
    10.                 stride=1,
    11.                 padding=0,
    12.                 bias_attr=False)
