A Data Science Central Community
The main focus of this article is on computing the point that minimizes the sum of the "distances" to n points in a d-dimensional space, called centroid or center, in the presence of outliers.
This long article has several sections.
1. A related physics problem
2. Algorithm to find the centroid
3. Examples and results
4. Convergence of the algorithm
5. Interesting Contour Maps
