By my understanding it seems that you want to create a similar architecture to googlenet.
You can refer to the link attached below for refering the googlenet architecture and you can use MATLAB function for creating the architecture:
Googlenet architecture: https://www.analyticsvidhya.com/blog/2018/10/understanding-inception-network-from-scratch/
MATLAB functions which will be helpful to create the architecture:
Also you can try using googlenet inbuilt architecture in MATLAB as a pre-trained network and train it for your dataset.
Hope it helps.
