ML_LSPARSDES
ML_LSPARSDES = [logical]
Default: ML_LSPARSDES = .FALSE.
Description: Specifies whether angular-descriptor sparsification is enabled within the machine learning force field method.
| Mind: This tag is only available as of VASP 6.4.3. |
To use the sparsification of angular descriptors set the following tags:
- ML_LSPARSDES=.TRUE..
- The ratio of the selected descriptors to the total number of descriptors: ML_RDES_SPARSDES. This tag controls the extent of the sparsification.
- The number of the highest eigenvalues [math]\displaystyle{ k }[/math] to which the correlation is measured via the leverage scoring: ML_NRANK_SPARSDES. This tag usually does not need to be changed.
