Instructions for making a Neural-Style movie

The following instructions are for creating your own animations using the style transfer technique described by Gatys, Ecker, and Bethge, and implemented by Justin Johnson. To see an example of such an animation, see this video of Alice in Wonderland re-styled by 17 paintings.

Setting up the environment

The easiest way to set up the environment is to simply load Samim's a pre-built Terminal.com snap or use another cloud service like Amazon EC2. Unfortunately the g2.2xlarge GPU instances cost $0.99 per hour, and depending on parameters selected, it may take 10-15 minutes to produce a 512px-wide image, so it can cost $2-3 to generate 1 sec of video at 12fps.

If you do load the

	library(rtweet)
	library(tidyverse)

	# Initial authorization setup, only need to do once
	# auth_setup_default() #nolint

	# Authorize
	auth_as("default")

	# Set user name


	## Singleton pattern
	Singleton <- setRefClass("Singleton",
	fields=list(
	Class="ANY",
	instance="ANY"
	),
	methods=list(
	initialize=function(...) {
	"Override this by defining Class"
