Artificial intelligence (AI) continues to be technology’s hot topic, growing exponentially in recent years. Many of the recent breakthroughs are the result of deep learning frameworks, where an app learns skills from an annotated dataset during training cycles. Also called machine learning, the framework applies this new knowledge to process new data.

When it comes to AI, you can choose from many different deep learning frameworks, depending on your needs. We’ll discuss some of the major ones in this blog, and outline each framework’s pros and cons.
