Frequently asked questions
What does Hyperparameter mean?
A setting chosen by people before or during model training, such as learning rate, batch size, or number of layers.
Is it something beginners need to understand?
Yes. You do not need to master the mathematics, but knowing the plain-English idea will make AI tools and articles much easier to follow.
Does every AI system use it?
Not necessarily. AI is a broad field, and different products use different architectures, training methods, data sources, and safety controls.
