You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: vid_create_net.m
    path of file: ./repos/siamese-fc/training
    
    the code of the file until where you have to start completion: % ----------------------------------------------------------------------------------------------------------------
function net = vid_create_net(varargin)
% Very similar to vanilla AlexNet from MatConvNet 
    
function net = vid_create_net(varargin)
% Very similar to vanilla AlexNet from MatConvNet examples,
% but with smaller stride at conv1 and no padding
% Used to generate the network described in  the paper
% "Fully-Convolutional Siamese Networks for Object Tracking"
