coranking package¶
Submodules¶
coranking.metrics module¶
-
coranking.metrics.
LCMC
(Q, min_k=1, max_k=None)[source]¶ Compute the local continuity meta-criteria (LCMC) metric over a range of K values.
Parameters: - Q – coranking matrix
- min_k – the lowest K value to compute. Default 1.
- max_k – the highest K value to compute. If None the range of values will be computer from min_k to n-1
Returns: array of size min_k - max_k with the corresponding LCMC values.
-
coranking.metrics.
continuity
(Q, min_k=1, max_k=None)[source]¶ Compute the continuity metric over a range of K values.
Parameters: - Q – coranking matrix
- min_k – the lowest K value to compute. Default 1.
- max_k – the highest K value to compute. If None the range of values will be computer from min_k to n-1
Returns: array of size min_k - max_k with the corresponding continuity values.
-
coranking.metrics.
trustworthiness
(Q, min_k=1, max_k=None)[source]¶ Compute the trustwortiness metric over a range of K values.
Parameters: - Q – coranking matrix
- min_k – the lowest K value to compute. Default 1.
- max_k – the highest K value to compute. If None the range of values will be computer from min_k to n-1
Returns: array of size min_k - max_k with the corresponding trustworthiness values.

coranking_matrix
(high_data, low_data)[source]¶ Generate a co-ranking matrix from two data frames of high and low dimensional data.
Parameters: - high_data – DataFrame containing the higher dimensional data.
- low_data – DataFrame containing the lower dimensional data.
Returns: the co-ranking matrix of the two data sets.
