Datalabeloinnissa, known in English as data labeling, is the process of assigning meaningful tags or labels to raw data, such as images, text, audio, or video. This labeled data is crucial for training and validating machine learning models, particularly in supervised learning algorithms. Without accurate and consistent labels, these models would struggle to learn patterns and make predictions.

The process involves human annotators or automated systems identifying specific features or categories within a dataset and applying corresponding labels. For instance, in image labeling, annotators might draw bounding boxes around objects like cars or pedestrians, classify images based on content, or identify key points on a person's body. For text data, labeling might involve sentiment analysis, named entity recognition, or categorizing documents. Audio data can be transcribed or speaker-identified, while video data can be labeled frame by frame to track objects or actions.

The quality of data labeling directly impacts the performance of the machine learning model. Inaccurate or inconsistent labels can lead to biased models that make errors. Therefore, establishing clear guidelines, employing skilled annotators, and implementing quality control measures are essential for effective data labeling. This field plays a foundational role in the development of AI applications across various industries, including autonomous vehicles, medical imaging analysis, natural language processing, and content moderation.
