Methods

__construct

Constructor.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ training_fraction float

The fraction of the input data that is to be used to train the Model.

↳ validation_fraction float

The fraction of the input data that is to be used to validate the Model.

↳ test_fraction float

The fraction of the input data that is to be used to evaluate the Model.

↳ key string

Required. The key is a name of one of the Dataset's data columns. The values of the key (the values in the column) must be in RFC 3339 date-time format, where time-offset = "Z" (e.g. 1985-04-12T23:20:50.52Z). If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline.
