Note - Convolution network: 1 × 1 convolution

• The first is the role of the convolution kernel

1.比全连接参数少很多的特征提取器
2.数据通道增加或减少

• 1x1 convolution kernel convolution kernel size and other different

用最少的参数实现数据通道地增加或减少

Reduce the data channel effects: reduce the amount of subsequent calculations, reducing the parameters

other views

• Non-linear increase
• It corresponds to a fully connected network

I feel less like
a 1 × 1 convolution kernel to do the whole connection, just 1 × 1 convolution kernel role of a special case
