In supervised learning, labels are very important. But what are labels?
Simply put, labels are the answers or results we want the computer to learn from a training dataset. They show the knowledge we want the computer to understand, helping it make accurate guesses.
When we give data to a supervised learning model, we usually have two parts:
Features: These are the input details or qualities of the data. For example, if we're trying to guess house prices, features could be the number of bedrooms, the location, and the size of the house.
Labels: These are the results we're trying to predict. In our house example, the label would be the actual price of the house.
While the model is being trained, it uses the labeled data to learn how features relate to labels. For instance, if it sees many houses with similar features and their prices, it starts to understand how different features affect the price. We can think of it as the model learning a function, where features tell it what to expect for the label.
After training, we can test the model with a new set of labeled data, which we call the validation set. This helps us check how accurate it is. For instance, if our housing model predicts a price of 290,000, the model has done well, even with a small mistake. This process helps us improve the model so it can make better guesses over time.
In short, labels are the foundation of supervised learning. They help models learn and let us see how well they are doing. Without labels, supervised learning would have no clear path and couldn't make useful predictions. So, next time you think about supervised learning, remember that labels are your guiding stars in the world of data!
