title: VGGNet fine-tuning: image size, time and epoch
body: <p>I am new in deep learning, I would like to have some clarification to understand the deep learning.</p>
  
  <p>I want to train my CNN model using VGGNet, should I use the same image size of VGGNet <strong>224x224</strong> input images for fine-tuning?</p>
  
  <p>How can I determine the number of <strong>epoch</strong>?</p>
  
  <p>How would it takes to train the model if the number of images is around 5000 images and the GPU Nvidia gtx 1070?</p>
  
  <p>Please help me to find answers. 
  Thank you</p>
