Imagine you're at a party, and you need to figure out who your best friend is, but instead of just asking people, you let everyone talk about what they like and how they feel about others.
Query, Key, and Value are names that help explain how this works in Transformers. Think of them like different roles at the party:
- The Query is like you, you're trying to find out who your best friend is.
- The Key is like a name tag, it helps others know who they are.
- The Value is like what someone says or does, it gives more details about them.
When you (the Query) talk to others, their Keys help you match up with the right person. Then, the Values give you clues about how close you really are.
It's like when you’re choosing your favorite toy from a pile: you look at each toy (Key), think about what it does (Value), and decide which one is best for you (Query).
This way, Transformers can understand relationships between words in a sentence, just like how you know who your best friend is by listening to what everyone says.
