PPE Models: Comparisons of Linear, Exponential, and Power-Law Visual Uncertainty

Model comparisons of the PPE models, which assume linear, exponential, or power-law visual uncertainty function. The dataset is a 12.7 KB XLSX file authored by Xiaoyue Zhang and last updated on April 15, 2026. It is shared under a CC-BY-4.0 license on the figshare platform.

Use Cases

• Compare the performance of linear, exponential, and power-law models based on the visual uncertainty functions described.
• Benchmark model fits for psychophysical data based on the described PPE model framework.
• Select a visual uncertainty function for perceptual modeling based on the comparative results.

Strengths

• Dataset is openly licensed (CC-BY-4.0) for reuse.
• File size is small (12.7 KB), enabling quick download and inspection.
• Provides a direct comparison of three specific model types (linear, exponential, power-law).

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
• The 12.7 KB file size indicates a very limited scope, likely containing summary results rather than raw experimental data.
