Now, let's delve deeper into training AI models. Why do we need hardware accelerators during this phase?
Because training requires a lot of computational power to adjust model weights, right?
Exactly! The backpropagation process, which adjusts weights, is computationally heavy and benefits immensely from the parallel processing power of GPUs and TPUs.
