Okay kiddo, let me tell you about committee machines! Imagine you have a big group of friends that all have different strengths. One friend might be really good at math, another might be really good at art, and another might be really good at sports. Now imagine you need to solve a really hard problem, like how to build the tallest tower with legos. You could ask each friend to come up with their own idea, or you could put them all together and have them work as a team to come up with the best idea.
A committee machine works kind of like that. It's a computer program that takes a bunch of smaller programs, called "committee members," and combines their ideas to come up with a better solution than any one of them could come up with alone. Each committee member might be really good at one aspect of the problem, like finding patterns or making predictions. By working together, they can use their different strengths to make a more accurate or efficient decision.
So, in short, a committee machine is like a group of friends working together to solve a problem, but with computer programs instead of actual people. It takes all of their different ideas and combines them to come up with the best solution possible.
