MobileNetの論文[1]では、その仕組みを以下のように紹介しています。 The MobileNet model is based on depthwise separable convolutions which is a form of factorized convolutions which factorize a standard convolution into a depthwise convolution and a 1×1 convolution called a pointwise convolution. MobileNets are small, low-latency, low-power models parameterized to meet the resource constraints of a variety of use cases. pbtxt must be inside the directory training. For those keeping score, that's 7 times faster and a quarter the size.
