Inception

def inception_module(in_tensor, c1, c3_1, c3, c5_1, c5, pp):
    conv1 = conv1x1(c1)(in_tensor)

    conv3_1 = conv1x1(c3_1)(in_tensor)
    conv3 = conv3x3(c3)(conv3_1)

    conv5_1 = conv1x1(c5_1)(in_tensor)
    conv5 = conv5x5(c5)(conv5_1)

    pool_conv = conv1x1(pp)(in_tensor)
    pool = layers.MaxPool2D(3, strides=1, padding='same')(pool_conv)

    merged = layers.Concatenate(axis=-1)([conv1, conv3, conv5, pool])
    return merged

最后采用了merged = layers.Concatenate进行融合
