我正在尝试实施这篇声音分类论文:

文中提到,每层增加0.001 L2重量衰减。但是,我不知道如何在Tensorflow中做到这一点。
我发现了一个类似的问题(
How to define weight decay for individual layers in TensorFlow?
)使用
tf.nn.l2_loss
,但尚不清楚如何将此方法用于我的网络。此外,它没有参数
0.001
在里面
tf。nn。l2\U损失
.
我的网络:
net = tf.layers.conv2d(inputs=x, filters=80, kernel_size=[57, 6], strides=[1, 1], padding="same", activation=tf.nn.relu)
print(net)
net = tf.layers.max_pooling2d(inputs=net, pool_size=[4, 3], strides=[1, 3])
print(net)
net = tf.layers.dropout(inputs=net, rate=keep_prob)
print(net)
net = tf.layers.conv2d(inputs=net, filters=80, kernel_size=[1, 3], strides=[1, 1], padding="same", activation=tf.nn.relu)
print(net)
net = tf.layers.max_pooling2d(inputs=net, pool_size=[1, 3], strides=[1, 3])
print(net)
net = tf.layers.flatten(net)
print(net)
# Dense Layer
net = tf.layers.dense(inputs=net, units=5000, activation=tf.nn.relu)
print(net)
net = tf.layers.dropout(inputs=net, rate=keep_prob)
print(net)
net = tf.layers.dense(inputs=net, units=5000, activation=tf.nn.relu)
print(net)
net = tf.layers.dropout(inputs=net, rate=keep_prob)
print(net)
logits = tf.layers.dense(inputs=net, units=num_classes)
print("logits: ", logits)
输出:
Tensor("Model/conv2d/Relu:0", shape=(?, 530, 129, 80), dtype=float32)
Tensor("Model/max_pooling2d/MaxPool:0", shape=(?, 527, 43, 80), dtype=float32)

我发现这篇论文的实施:
https://github.com/karoldvl/paper-2015-esc-convnet/blob/master/Code/_Networks/Net-DoubleConv.ipynb
但是,它在
pylearn2
.
如何在代码中添加0.001 L2权重衰减?
