[EN] This paper compares various proposals for codifying categorical attributes in a heart disease database
so that numerical clustering algorithms can be applied to them. An approach for the codification of
categorical attributes based on polar coordinates is proposed. This is compared with other codifications
and methods for clustering mixed databases found in the literature.
Our proposal has many advantages: it is relatively easy to understand and apply; the increment in
the length of the input matrix is not excessively large; and the committed error is under control. The
proposed codification has been combined in this case with the well-known k-means algorithm and has
shown a very good performance in a heart disease database benchmark.
