What are dataset annotation

About dataset annotation

Dataset annotation involves adding metadata, labels, or tags to raw data, usually in the form of images, to enhance its understanding and utility for machine learning models. This annotated data helps train and improve the accuracy of algorithms by providing labeled examples for the model to learn from. The annotations could include bounding box method, or any other relevant information depending on the specific goals of the machine learning task.
