I am implementing ApesNet in keras. It has an ApesBlock that has skip connections. How do I add this to a sequential model in keras? The ApesBlock has two parallel layers that merge at the end by element-wise addition.
简单的答案是不要为此使用顺序模型,而是使用函数式 API,实现跳过连接(也称为残差连接)非常容易,如以下示例所示功能API指南 https://keras.io/getting-started/functional-api-guide/:
from keras.layers import merge, Convolution2D, Input
# input tensor for a 3-channel 256x256 image
x = Input(shape=(3, 256, 256))
# 3x3 conv with 3 output channels (same as input channels)
y = Convolution2D(3, 3, 3, border_mode='same')(x)
# this returns x + y.
z = merge([x, y], mode='sum')
