Ground Truth

Ground truth refers to information that is considered the most accurate and reliable source of facts about a situation or environment. In various fields, such as science, data analysis, and machine learning, ground truth serves as a benchmark against which models, theories, or observations are measured. For instance, in image classification, ground truth would be the correct labels for images, helping to assess how well a system performs. Essentially, it represents the verified reality that researchers and analysts use to validate their findings or improve their methods.
