What is Data Annotation?
Data annotation is the process of labeling or marking up raw data such as text, images, audio, or video, to help artificial intelligence (AI) and machine learning (ML) models learn and understand that data. This process enables computers to recognize objects, attributes, or behaviors within the data and provides the essential context needed for AI and ML models to function effectively.
Types of Data Annotation
Data annotation plays a vital role in developing accurate and reliable machine learning models. It encompasses a wide range of data types, including text, images, videos, audio, 3D data (such as LiDAR), and segmentation tasks.
