How Do I Start Using Deep Learning?
Where you start depends on what you already know.
The prerequisites for understanding and applying deep learning are linear algebra, calculus and statistics, as well as programming and some machine learning.
In the case of Deeplearning4j, you should know Java well and be comfortable with tools like the IntelliJ IDE and the automated build tool Maven.
Below you’ll find a list of resources. The sections are roughly organized in the order they will be useful.

If you do not know how to program yet, you can start with Java, but you might find other languages easier. Python and Ruby resources convey the basic ideas in a faster feedback loop.
- Learn Python the Hard Way
- Pyret: A Python Learning Environment
- Scratch: A Visual Programming Environment From MIT
- Learn to Program (Ruby)
- Intro to the Command Line
- Additional command-line tutorial
- A Vim Tutorial and Primer (Vim is an editor accessible from the command line.)
- Intro to Computer Science (CS50 @Harvard edX)

Once you have programming basics down, tackle Java, the world’s most widely used programming language, and the language of Hadoop.
- Java Resources
- Java Ranch: A Community for Java Beginners
- Intro to Programming in Java @Princeton

With that under your belt, we recommend you approach Deeplearning4j through its examples.
Once you get those up and running, and you’ve understood the API, you’re ready for a full install.
Most of what we know about deep learning is contained in academic papers.
We’ve linked to a number of them here.
While individual courses have limits on what they can teach, the Internet does not. Most math and programming questions can be answered by Googling and searching sites like Stackoverflow and Math Stackexchange.
