Unlocking the Power of Annotated Data: The Catalyst for Machine Learning Excellence - Understanding the Ground Truth Provided by Annotated Data
Annotated data is a crucial component of machine learning as it provides the "ground truth" or the correct answer that models aim to achieve.
Ground truth data is typically verified by domain experts to ensure its accuracy and reliability in machine learning.
Annotated data includes not only a label but also additional information, making it more informative than labeled data alone.
The ground truth is used as a "gold standard" to compare and evaluate machine learning model results, ensuring that the models are performing as expected.
