Medium	GrooveSquid.com (original content)	Medium Difficulty Summary A new paper proposes a two-stage framework called SCIU (Seeking Certain data In extensive Uncertain data) to improve the quality of Dynamic Facial Expression Recognition (DFER) datasets. The current state-of-the-art DFER technology relies on large datasets, but these datasets often contain noise due to low-quality captures and annotation bias. The proposed framework aims to address two types of uncertainty: data usability and label reliability. The first stage, Coarse-Grained Pruning (CGP), evaluates sample weights and removes samples deemed unusable. The second stage, Fine-Grained Correction (FGC), corrects mislabeled data by evaluating prediction stability. The framework is designed to be universally compatible with prevailing DFER methodologies and has been tested across various datasets and benchmark methods, demonstrating significant improvements in performance metrics.
Low	GrooveSquid.com (original content)	Low Difficulty Summary A new approach called SCIU helps improve facial expression recognition technology. Right now, this tech relies on big datasets, but those datasets often have mistakes. The new method tries to fix two types of problems: making sure the data is good quality and fixing mistakes in how the data was labeled. It does this by using two stages: one that gets rid of bad data and another that corrects the mistakes. This approach can be used with existing methods and has been tested to show big improvements.
