This procedure explains how to install MongoDB using Homebrew on macOS Sierra 10.12.
Official MongoDB install documentation: here

Install Homebrew

Installing Homebrew is effortless, open Terminal and enter :
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Machine Learning Curriculum

The Batch Normalization paper describes a method to address the various issues related to training of Deep Neural Networks. It makes normalization a part of the architecture itself and reports significant improvements in terms of the number of iterations required to train the network.

Issues With Training Deep Neural Networks

Internal Covariate shift

Covariate shift refers to the change in the input distribution to a learning system. In the case of deep networks, the input to each layer is affected by parameters in all the input layers. So even small changes to the network get amplified down the network. This leads to change in the input distribution to internal layers of the deep network and is known as internal covariate shift.

It is well established that networks converge faster if the inputs have been whitened (ie zero mean, unit variances) and are uncorrelated and internal covariate shift leads to just the opposite.

Install MySQL on OS X El Capitan

Normally the installation of MySQL can be achieved with a single command, which executes a script provided by MacMiniVault : bash <(curl -Ls http://git.io/eUx7rg)

However, at the time of writing the script is not compatible with OS X El Capitan (10.11)

Install MySQL using Homebrew

An alternative to the aforementioned installation script is installing MySQL using Homebrew. This gist assumes you already have Homebrew installed, if not first read the article "Homebrew and El Capitan"

Make sure Homebrew has the latest formulae, so run brew update first

	# PS does but it does but you need PIDs for that
	# lsof /dev/nvidia gives PIDs but only for the user invoking it

	# usage:
	# python programs_on_gpu.py
