Demographic differences among annotators significantly affect sentiment dataset labels, causing up to a 4.5% accuracy difference in sentiment prediction models.
Methods: Crowdsourced annotations from >1000 workers combined with demographic data; analysis of multimodal sentiment datasets and evaluation using machine learning models.
Key Findings: Impact of annotator demographics on sentiment labeling and its effect on model predictions.

Humans outperform machine learning models in classifying real human audio versus deepfakes, but are often misled by preconceptions about generated content, highlighting the need for more synergistic approaches between human and machine decision-making.
Methods: A large-scale user study was conducted where over 1,200 participants evaluated audio samples from three widely-cited deepfake datasets. Performance was quantitatively measured and thematic analysis was used to explore user reasoning and differences from machine classification.
Key Findings: Comparison of human and machine classification performance on audio deepfake detection, analysis of user reasoning, and evaluation of error patterns between both humans and models.
