Parameters

The parameters are represented by the pair (exponent, factor). The pair of values (0.00, 0.00) serves as a baseline, as this means that the indices in the color palettes are not taken into account to weigh color distances in the formula for palette distances.

Results

The results are shown as:

• statistics (min, median, mean, max) about the rank of the retrieved apps,
• a score which is the sum of these statistics. The lower the score, the better.

Benchmarks

A few benchmarks are shown below:

• Top 2,000: a benchmark based on the top 2,000 popular apps,
• Top 20,000: a benchmark based on the top 20,000 popular apps,
• Top 67,000: a benchmark based on all the 66,659 popular apps,
• Top 100,000: a benchmark without any popularity-based constraint.
