Are you tired of relying on your local weatherman for your daily weather forecast? Do you want to take matters into your own hands and predict the weather yourself? Well, have no fear, because I'm going to teach you how to create a basic machine learning program in C to predict the weather!
But first, let me introduce you to our data. We have four sets of weather parameters, including temperature, humidity, air pressure, and wind speed, and their corresponding temperatures. With this data, we will train a linear regression model to make predictions on future weather conditions.
Now, let's dive into the code. First, we define our learning rate and number of iterations. If you don't know what these terms mean, don't worry, we'll explain them later. Then, we define our predict function that takes in our model's parameters (theta) and a set of weather parameters (x), and outputs a predicted temperature.
Our main function initializes our dataset and model parameters to zero. We then iterate through our dataset for a specified number of iterations, and for each iteration, we iterate through each data point to update our model parameters using stochastic gradient descent. If you're wondering what stochastic gradient descent means, it's a fancy way of saying that we're updating our model parameters by taking small steps in the direction of the steepest gradient of the cost function (mean squared error in our case). This is done to minimize the difference between our predicted temperature and the actual temperature.
Finally, we test our trained model by feeding it a new set of weather parameters and outputting the predicted temperature.
Linear regression with stochastic gradient descent may sound like a mouthful, but it's just a fancy way of saying we're drawing a line to predict the weather and adjusting it one small step at a time to get as close to the actual temperature as possible. It's like trying to hit a bullseye blindfolded, but with a lot of practice and a little bit of luck, we'll get pretty close!
And there you have it, folks! A simple machine learning program in C to predict the weather. Now you can impress your friends with your newfound weather forecasting skills. Just don't blame me if the weatherman gets jealous!
