What are feed-forward networks?

A feed-forward network is like a smart message-passing line that helps you solve problems step by step.

Imagine you're trying to guess what kind of fruit is in a bag, maybe it's an apple or a banana. You can't see inside, but you can feel its shape and smell its scent. A feed-forward network works the same way: it takes clues (like touch and smell), passes them through layers of helpers (like friends who know about fruits), and finally gives you an answer.

Think of each layer as a group of friends who do part of the job:

• The first friends check the shape, is it round or long?
• The next friends look at the smell, does it remind them of apples or bananas?
• Finally, the last friends put all that together and decide: apple or banana?

Each friend uses what they know to send a message forward. That’s why we call it a feed-forward network, the messages only go forward, not backward.

And just like you get better at guessing fruits with more practice, these networks get smarter when they learn from many examples!
