• Abstract: The need for dietary data management is growing with public awareness of food intakes. As a result, there are increasing deployments of smart canteens where dietary data is collected through either Radio Frequency Identification (RFID) or Computer Vision(CV)-based solutions. As human labor is involved in both cases, manpower allocation is critical to data quality. Where manpower requirements are underestimated, data quality is compromised. This paper has studied the relation between the quality of dietary data and the manpower invested, using numerical simulations based on real data collected from multiple smart canteens. We found that in both RFID and CV-based systems, the long-term cost of dietary data acquisition is dominated by manpower. Our study provides a comprehensive understanding of the cost composition for dietary data acquisition and useful insights toward future cost effective systems.

  We argue that the widespread use of large language models threatens the quality and integrity of human-generated data. Existing data collection systems prioritize speed, scale, and efficiency at the cost of intrinsic human motivation. We propose that rethinking data collection systems to align with contributors' intrinsic motivations.

  Medical Imaging (MI) datasets are fundamental to artificial intelligence in healthcare. MI datasets used to be proprietary, but have become increasingly available to the public, including on community-contributed platforms (CCPs) like Kaggle or HuggingFace. While open data is important to enhance the redistribution of data's public value, we find that the current CCP governance model fails to uphold the quality needed and recommended practices for sharing, documenting, and evaluating datasets.

  Given a small training data set and a learning algorithm, how much more data is necessary to reach a target validation or test performance? Overestimating or underestimating data requirements incurs substantial costs that could be avoided with an adequate budget. Using our guidelines, practitioners can accurately estimate data requirements of machine learning systems to gain savings in both development time and data acquisition costs.
