WebJul 28, 2016 · In my real life example, I obtain very poor accuracy using P > 0.5 as my classifying cutoff (about 51% accuracy). However, when I looked at the AUC it is above 0.99. So I looked at some different cutoff values and found that P > 0.6 gave me 98% accuracy (90% for the smaller class and 99% for the bigger class) - only 2% of cases misclassified. WebPlane-Wave Basis Sets. There is a further truncation of plane wave expansion in plane-wave calculations. Namely, only the reciprocal lattice vectors whose kinetic energy lower than a predefined maximum cutoff energy, are kept in the expansion, while the rest of the coefficients are set to zero.

"WebAug 26, 2016 · Generally in the DFT codes the cutoff radius is set/fixed in the psp as they can significantly effect the results. The energy cut off entirely depends on what system studied (atoms), what kind of potential used. If the Rcut is increased, one has more freedom to play with the shape of wavefunction and hence make smoth (small basis set -> cut off). " - Increase cutoff_energy or basis_precision
