Troubleshooting Convolutional Neural Networks

Intro

This is a list of hacks gathered primarily from prior experiences as well as online sources (most notably Stanford's CS231n course notes) on how to troubleshoot the performance of a convolutional neural network . We will focus mainly on supervised learning using deep neural networks. While this guide assumes the user is coding in Python3.6 using tensorflow (TF), it can still be helpful as a language agnostic guide.

Suppose we are given a convolutional neural network to train and evaluate and assume the evaluation results are worse than expected. The following are steps to troubleshoot and potentially improve performance. The first section corresponds to must-do's and generally good practices before you start troubleshooting. Every subsequent section header corresponds to a problem and the section is devoted to solving it. The sections are ordered to reflect "more common" issues first and under each header the "most-eas

Sharing Host VPN with VirtualBox guest

Actually, this already works using VirtualBox’s NAT networking mode in your guest. What doesn’t work is resolving domain names from the guest that are only known in the VPN network.

So if you have a a domain like w3.mycompany.com that only resolves using the VPN’s DNS, you can resolve that name from your host (which is connected to the VPN), but not from your guest by default. You won’t be able to ping w3.mycompany.com from the guest. However, if you try to ping the IP address from your guest, that works.

To solve this, VirtualBox has a nice feature to allow you to set the Host DNS resolver as the DNS proxy of a VirtualBox VM. To configure this, you first need to figure out the id of your VirtualBox VM:

$ VBoxManage list vms

	# Sample Nginx config with sane caching settings for modern web development
	#
	# Motivation:
	# Modern web development often happens with developer tools open, e. g. the Chrome Dev Tools.
	# These tools automatically deactivate all sorts of caching for you, so you always have a fresh
	# and juicy version of your assets available.
	# At some point, however, you want to show your work to testers, your boss or your client.
	# After you implemented and deployed their feedback, they reload the testing page – and report
	# the exact same issues as before! What happened? Of course, they did not have developer tools
	# open, and of course, they did not empty their caches before navigating to your site.
