/* Output:
 * Stochastic gradient descent is a method used in machine learning to adjust parameters of a model.
 * It's similar to another method called gradient descent. The main difference is that stochastic gradient
 * descent updates the parameters of the model after looking at each individual training example, one at a time,
 * instead of using the entire dataset at once.
 * 
 * For example, imagine you are trying to teach a robot to recognize apples. In stochastic gradient descent,
 * you would show the robot one apple picture at a time, update its understanding based on that single picture,
 * then move to the next one. In contrast, traditional gradient descent would look at all of the pictures of apples
 * together before making any updates.
