Feature vector

A feature vector is like a list of things we know about a thing or a person. Imagine your friend asking you to tell them about your pet. You might say your pet's name, color, breed, and favorite toy. These things are features of your pet that help your friend identify and recognize it.

In a computer, we also use feature vectors to describe things in a way computers can understand. For example, if we want to teach a computer to recognize different types of fruits, we might create feature vectors based on color, shape, weight, and texture of the fruits.

Each feature in a feature vector is like a piece of information that tells us something about the thing we are describing. These features are used to help us tell things apart from each other. Just like how we can recognize our friends based on their different features like hair color, height, or clothes they wear, a computer can recognize different things based on their feature vectors.
