Top 10 C/C++ Libraries for Machine Learning you should know


Here are the top 10 best C/C++ libraries for Machine Learning that you should know

Machine Learning is the latest buzzword floating around. It deserves to, as it is one of the most interesting subfields of Computer Science. So what does Machine Learning really mean? Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it to learn for themselves.

Why devs use C++ for Machine Learning?

If you are aware of Machine Learning basics you must know that one of the crucial steps, in order to learn machine learning if you are an engineer, is to implement algorithms from scratch.  In that case, I’d agree that there are languages with better ready-to-use libraries. But, if you are going to implement an algorithm from scratch and you are familiar with C++, why wouldn’t you use that language? The only obvious reason is that C++ is a much harder language to deal with than, say, Python.

However, again, if you are familiar with the intricacies of the language (memory allocation, pointers, references, templates, then I think it is actually a plus that you use C++ instead of a more “user-friendly” language.

Another reason for using C++ for Machine Learning is that, as you mention, C++ is more efficient than most other languages. And, important libraries such as TensorFlow and Torch are implemented in C++ under the hood. As a matter of fact, many companies implement their machine learning algorithms in C++. Sure, they will also use Python and R for experimentation and prototyping, but many of the production algorithms will end up in C++.

So let’s take a look at the top 10 best C/C++ libraries that you can use for your Machine Learning project.
