What is the metric? Per suggestion by @scottgigante https://github.com/scottgigante - use a correlation (i.e., Pearson's, Spearman's) to describe the quality of low-dimension distances as they relate to the original, high-dimension differences.
How should it be implemented?
- Pearson's Correlation Coefficient https://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.stats.pearsonr.html
- Spearman rank-order correlation coefficient https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.spearmanr.html
Which task(s) could it be used for?
- Dimension reduction
