Large language models like ChatGPT and Bard have raised machine learning to the status of a phenomenon. Their use for coding assistance has quickly earned these tools a place in the developer’s toolkit. Other use cases are being explored, ranging from image generation to disease detection. Tech companies are investing heavily in machine learning, so knowing how to train and work with models is becoming essential for developers.
This article gets you started with machine learning in Java. You will get a first look at how machine learning works, followed by a short guide to implementing and training a machine learning algorithm. We’ll focus on supervised machine learning, which is the most common approach to developing intelligent applications.
Supervised learning involves training a model on labeled data, where the input features and the corresponding output labels are known. This method allows the model to learn the relationship between inputs and outputs, enabling it to make predictions on new, unseen data. We’ll use a common algorithm, gradient descent, to train our first prediction function.
Gradient descent is an optimization technique used to minimize the cost function of a machine learning model. By iteratively adjusting the model’s parameters, gradient descent helps find the optimal values that reduce the prediction error. This process involves calculating the gradient of the cost function with respect to each parameter and updating the parameters in the opposite direction of the gradient.
To implement gradient descent in Java, we first need to set up a supervised learning project. This involves preparing a dataset, defining the prediction function, and initializing the model’s parameters. We’ll then write a loop that performs the gradient descent steps, updating the parameters until the cost function converges to a minimum.
By following this guide, you’ll gain a foundational understanding of machine learning concepts and how to apply them in Java. This knowledge will enable you to explore more advanced algorithms and techniques, ultimately helping you build intelligent applications that can learn from data and make accurate predictions.
