Bilinear¶

class paddle.nn.initializer. Bilinear ( ) ) [源代码] ¶

该接口为参数初始化函数，用于转置卷积函数中，对输入进行上采样。用户通过任意整型因子放大 shape 为(B，C，H，W)的特征图。

返回¶

对象

用法如下：

          import math

import paddle
import paddle.nn as nn
from paddle.regularizer import L2Decay

factor = 2

                          regularizer=L2Decay(0.),
                          initializer=nn.initializer.Bilinear())
data = paddle.rand([B, 3, H, W], dtype='float32')

                             out_channels=C,

                                 math.ceil((factor - 1) / 2.)),
