v1.6.1

Bug Fixes

Fixed a bug in mean_average_precision in AccuracyCalculator. Previously, the divisor for each sample was the number of correctly retrieved samples. In the new version, the divisor for each sample is min(k, num_relevant).

For example, if class "A" has 11 samples, then num_relevant is 11 for every sample with the label "A".

• If k = 5, meaning that 5 nearest neighbors are retrieved for each sample, then the divisor will be 5.
• If k = 100, meaning that 100 nearest neighbors are retrieved for each sample, then the divisor will be 11.

The bug in previous versions did not affect mean_average_precision_at_r.

Other minor changes

Added additional shape checks to AccuracyCalculator.get_accuracy.
