The accuracy and reliability of AI models depend on the quality of the data they are trained on, with "Garbage In, Garbage Out" (GIGO) being a foundational concept in computing and data science emphasizing that input data determines output quality. Poorly curated data can undermine AI models, leading to inaccurate predictions and business consequences such as financial losses. Common pitfalls in data curation include incomplete, biased, outdated, inconsistent, and annotated errors, which can be addressed through techniques like data augmentation and robust labeling processes. Leveraging tools like Encord can help manage, clean, and curate data, ensuring consistent and high-quality annotations and improving model performance.
