load_data(doe, data, process_parameters, position, output, categorical=[], angle=False, index='doe_id', validation_split=0.1, validation_method='random', position_scaler='normal')
#
Loads pandas Dataframes containing the data and preprocesses it.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
doe |
pandas.Dataframe object containing the process parameters (design of experiments table). |
required | |
data |
pandas.Dataframe object containing the experiments. |
required | |
process_parameters |
list of process parameters ti be used. The names must match the columns of the csv file. |
required | |
categorical |
list of process parameters that should be considered as categorical nad one-hot encoded. |
[]
|
|
position |
position variable. The name must match one column of the csv file. |
required | |
output |
output variable(s) to be predicted. The name must match one column of the csv file. |
required | |
angle |
if the position parameter is an angle, its sine and cosine are used as inputs instead. |
False
|
|
index |
name of the column in doe and data representing the design ID (default: 'doe_id') |
'doe_id'
|
|
validation_split |
percentage of the data used for validation (default: 0.1) |
0.1
|
|
validation_method |
method to split the data for validation, either 'random' or 'leaveoneout' (default: 'random') |
'random'
|
|
position_scaler |
normalization applied to the position attributes ('minmax' or 'normal', default 'normal') |
'normal'

predict(process_parameters, positions, as_df=False)
#
Predicts the output variable for a given number of input positions (uniformly distributed between the min/max values used for training).
Parameters:
Name | Type | Description | Default |
---|---|---|---|
process_parameters |
dictionary containing the value of all process parameters. |
required | |
positions |
number of input positions to be used for the prediction. |
required | |
as_df |
whether the prediction should be returned as numpy arrays (False, default) or pandas dataframe (True). |
False
