C-class (Classification) refers to a system used to categorize items, organisms, or concepts based on shared characteristics. This method helps in organizing information, making it easier to study and understand various subjects. For example, in biology, organisms are classified into groups like kingdoms, phylum, and species based on their traits. In machine learning, C-class classification involves assigning labels to data points based on their features. This process is essential for tasks like image recognition or spam detection, where algorithms learn to distinguish between different categories. Effective classification improves the accuracy of predictions and enhances decision-making processes.
