The bakery dataset contains the demand for a number of products from different stores. Moreover, it stores a number of demand features. A description of targets and features is given below.

Dataset Characteristics:

Number of Instances

127575

Number of Targets

1

Number of Features

Target Information

  • ‘demand’ the corresponding demand observation

Feature Information

  • ‘date’ the date

  • ‘weekday’ the day of the week,

  • ‘month’ the month of the year,

  • ‘year’ the year,

  • ‘is_holiday’ whether or not it is a national holiday,

  • ‘promotion_lastweek’ whether there was a promotion last week

Parameters

  • include_date (bool, default=False) – Whether to include the demand date

  • one_hot_encoding (bool, default=False) – Whether to one hot encode categorical features

  • label_encoding (bool, default=False) – Whether to convert categorical columns (weekday, month, year) to continuous. Will only be applied if one_hot_encoding=False

  • return_X_y (bool, default=False.) – If True, returns (data, target) instead of a Bunch object. See below for more information about the data and target object.

Returns

  • data (sklearn Bunch) – Dictionary-like object, with the following attributes.
