I gave a presentation on this a bit ago:

• Kaggle(www.kaggle.com) is a good start for this - start with “somewhat real” problems • Use higher level tools - Keras(https://keras.io/), otherwise easy to get lost in weeds • Consider having a real world goal - eg: if you’re in real estate figure out how to use a simple CNN (not the latest algorithm) for image search • Depending on need consider integration with hadoop/Spark(http://spark.apache.org/)
