What are Data Annotation & Labeling Services?

Data is the key to success in today’s rapidly growing field of AI and ML. However, this is not enough, as raw data that are not labeled or annotated cannot activate intelligent algorithms.

Velan’s Data annotation and Data labeling services are used by businesses to handle large amounts of data to get useful information from it.

Data annotation is a process of assigning labels to the data, and such data could be text, images, videos, or audio. This is because most of the AI models require labeled data to enhance their comprehension and forecasts.

Partnering with a reliable AI data annotation outsourcing company helps your business get clean and accurate datasets that enhance the performance of an AI model.

Velan specializes in custom data annotation and labeling solutions that help companies gain the agility and knowledge they require to grow their AI projects.
