• paddle.fluid.regularizer.L1Decay
• L1DecayRegularizer 的别名

L1DecayRegularizer

SourceEnglish

• class paddle.fluid.regularizer.L1DecayRegularizer(regularization_coeff=0.0)
• 实现 L1 权重衰减正则化。

L1正则将会稀疏化权重矩阵。

• 参数:
• • regularization_coeff (float) – 正则化系数代码示例

ioptimizer = fluid.optimizer.Adagrad(
                        learning_rate=1e-4,
                        regularization=fluid.regularizer.L1DecayRegularizer(
                         regularization_coeff=0.1))
optimizer.minimize(avg_cost)

L2DecayRegularizer

SourceEnglish

• class paddle.fluid.regularizer.L2DecayRegularizer(regularization_coeff=0.0)
• 实现L2 权重衰减正则化。

较小的 L2 的有助于防止对训练数据的过度拟合。

• 参数:
• • regularization_coeff (float) – 正则化系数代码示例

optimizer = fluid.optimizer.Adagrad(
                         learning_rate=1e-4,
                         regularization=fluid.regularizer.L2DecayRegularizer(
                         regularization_coeff=0.1))
 optimizer.minimize(avg_cost)
