vastorbit.datasets.gen_meshgrid¶

vastorbit.datasets.gen_meshgrid(features_ranges: dict) → VastFrame¶

Generates a dataset using regular steps.

Parameters:

features_ranges (dict) –

Dictionary including the features types and ranges.

For str:
The subdictionary must include two keys: “type” must be set to ‘str’ and ‘value’ must include the feature categories.

For int:
The subdictionary must include two keys: “type” must be set to ‘int’ and ‘range’ must include two integers that represent the lower and the upper bounds.

For float:
The subdictionary must include two keys: “type” must be set to ‘float’ and ‘range’ must include two floats that represent the lower and the upper bounds.

For date:
The subdictionary must include two keys: “type” must be set to ‘date’ and ‘range’ must include the start date and the number of days after.

For datetime:
The subdictionary must include two keys: “type” must be set to ‘date’ and ‘range’ must include the start date and the number of days after.

Numerical and date-like features must have an extra key in the dictionary named ‘nbins’, which corresponds to the number of bins used to compute the different categories.

Returns:

Generated dataset.

Return type:

VastFrame
