Definition
Data-centric AI represents a paradigm shift in artificial intelligence development, focusing on systematically improving the data used to train models rather than solely optimizing algorithms or hyperparameters. Proponents argue that high-quality, well-labeled, and diverse datasets yield better performance gains than complex model tweaks. This methodology involves rigorous data auditing, labeling consistency checks, and iterative data refinement. By treating data as a first-class citizen, organizations can build more robust, fair, and accurate AI systems with less computational overhead.
