Aggregation Function

PyALAF.aggregation_fn.conductivity_aggregation_fn(x, features, uncert=False, delta_beta=0, scaler=None, use_features=True)[source]

Calculate the ionic conductivity from S0, S1 and S2 objectives from the generalized Arrhenius fit.

Parameters:
  • x (nd_array of dimension 2) – Array that contains three columns for each of the S0, S1 and S2 objectives and as many rows as data points.

  • delta_beta (float) – Difference between 1/T and 1/T_0.

Returns:

The ionic conductivity for each data point.

Return type:

nd_array of dimension 1
