ML LSPARSDES

ML_LSPARSDES = [logical]
Default: ML_LSPARSDES = .FALSE.

Description: This tag specifies whether angular descriptor sparsification is enabled within the machine learning force field method.

For details on the theory how angular descriptor are sparsified see here.

To use the sparsification of angular descriptors set the following tags:

ML_LSPARSDES=.TRUE..
The number of the highest eigenvalues $k$ to which the correlation is measured via the leverage scoring: ML_NRANK_SPARSDES.
The ratio of the selected descriptors to the total number of descriptors: ML_RDES_SPARSDES. This tag controls the extent of the sparsification.
