What is a GPU? Are GPUs Needed for Deep Learning?

In the age of the intelligent era, more and more innovative concepts emerge daily. One of them is undoubtedly the field of "artificial intelligence." In this case, specifically, "deep learning," a sub-branch of AI, will encounter us when we need to dive deeper into complex problems, and it is used in many areas today. We develop deep learning models to achieve specific tasks, and in some cases, surpass human, repetitive capabilities. In this article, we will explore how the GPU is used for deep learning with code examples.
