ML W1: Difference between revisions

ML_W1 = [real]
Default: ML_W1 = 0.1

Description: This tag defines the weight $\beta$ for the radial (and angular) descriptor within the machine learning force field method (see this section).

The weight for the angular descriptor $W_{2}$ is internally computed from the weight of the radial descriptor $W_{1}$ as:

$W_{2}=1.0-W_{1}.$

The value for ML_W1 must be chosen in the interval $[0,1]$ .

By default, the angular and radial descriptors are both used although the latter is weighed less. In principle a weight of 0 for one of them is selectable which allows the code to internally skip the respective computation. However, it is generally recommended to use both descriptors to achieve satisfying training results.
