High-quality data is crucial for training modern deep learning models. Most task-specific labeled data comes from human annotation, such as classification tasks or reinforcement learning from human feedback (RLHF) labeling. Human data collection involves attention to detail and careful execution. The community recognizes the importance of high-quality data, but there's a perception that people prefer working on model development rather than data preparation. --- Why it matters: This matters because poor quality data can lead to biased or inaccurate models, which can have significant consequences in applications such as healthcare, finance, and education. Ensuring high-quality data is essential for developing reliable AI systems. Source: https://lilianweng.github.io/posts/2024-02-05-human-data-quality/
