clinical_kernel
(x, y=None)[source]¶ Computes clinical kernel
The clinical kernel distinguishes between continuous ordinal,and nominal variables.
See [1] for further description.
Parameters: - x (pandas.DataFrame, shape = (n_samples_x, n_features)) – Training data
- y (pandas.DataFrame, shape = (n_samples_y, n_features)) – Testing data
Returns: kernel – Kernel matrix. Values are normalized to lie within [0, 1].
Return type: array, shape = (n_samples_x, n_samples_y)
