19. def toTimePeriod(period: TimePeriod): FeatureLike[Integral]

    

    Convert to specified time period

    Convert to specified time period

    period

    type of TimePeriod to convert date feature to

    returns

    Integer feature of time period value

20. def toUnitCircle(timePeriod: TimePeriod = TimePeriod.HourOfDay, others: Array[FeatureLike[Date]] = Array.empty): FeatureLike[OPVector]

    

    transforms a Date field into a cartesian coordinate representation of an extracted time period on the unit circle

    transforms a Date field into a cartesian coordinate representation of an extracted time period on the unit circle

    timePeriod

    The time period to extract from the timestamp

    others

    Other features of same type enum from: DayOfMonth, DayOfWeek, DayOfYear, HourOfDay, WeekOfMonth, WeekOfYear

21. def vectorize(dateListPivot: DateListPivot, referenceDate: DateTime = ..., trackNulls: Boolean = TransmogrifierDefaults.TrackNulls, circularDateReps: Seq[TimePeriod] = ..., others: Array[FeatureLike[Date]] = Array.empty): FeatureLike[OPVector]

    

    Converts DateTime features into cartesian coordinate representation of an extracted time periods (specified in circularDateRepresentations as seq of: DayOfMonth, DayOfWeek, DayOfYear, HourOfDay, WeekOfMonth, WeekOfYear) on the unit circle.

    Converts DateTime features into cartesian coordinate representation of an extracted time periods (specified in circularDateRepresentations as seq of: DayOfMonth, DayOfWeek, DayOfYear, HourOfDay, WeekOfMonth, WeekOfYear) on the unit circle. Also converts a sequence of Date features into DateList feature and then applies DateList vectorizer.

    DateListPivot can specify: 1) SinceFirst - replace the feature by the number of days between the first event and reference date 2) SinceLast - replace the feature by the number of days between the last event and reference date 3) ModeDay - replace the feature by a pivot that indicates the mode of the day of the week Example : If the mode is Monday then it will return (1.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0) 4) ModeMonth - replace the feature by a pivot that indicates the mode of the month 5) ModeHour - replace the feature by a pivot that indicates the mode of the hour of the day.

    dateListPivot

    name of the pivot type from DateListPivot enum

    referenceDate

    reference date to compare against when DateListPivot is SinceFirst or SinceLast

    trackNulls

    option to keep track of values that were missing

    circularDateReps

    list of all the circular date representations that should be included in feature vector

    others

    other features of same type

    returns

    result feature of type Vector
