In this article, we'll go through an overview of Artificial Intelligence (AI) libraries in Java.
Some theoretical knowledge of AI would be helpful in understanding the use of these libraries.
AI is a very wide field, so we will be focusing on some of the most popular fields today, like Natural Language Processing, Machine Learning, and Neural Networks. In the end, we'll see some interesting AI challenges where we can practice our understanding of AI.
