Defined in:

Overview

Training pipeline will perform following transformation functions.

• Apply the transformation functions for Numerical columns.
• Determine the year, month, day,and weekday. Treat each value from the
• timestamp as a Categorical column.
• Invalid numerical values (for example, values that fall outside of a typical timestamp range, or are extreme values) receive no special treatment and are not removed.

Instance Attribute Summary

• #column_name ⇒ ::String
• #invalid_values_allowed ⇒ ::Boolean

  If invalid values is allowed, the training pipeline will create a boolean feature that indicated whether the value is valid.

• #time_format ⇒ ::String

  The format in which that time field is expressed.

Instance Attribute Details

#column_name ⇒ ::String

Returns:

• (::String)

class TimestampTransformation

end

#invalid_values_allowed ⇒ ::Boolean

Returns If invalid values is allowed, the training pipeline will create a boolean feature that indicated whether the value is valid. Otherwise, the training pipeline will discard the input row from trainining data.

Returns:

• (::Boolean) —

end

#time_format ⇒ ::String

Returns The format in which that time field is expressed. The time_format must either be one of:

• unix-seconds
• unix-milliseconds
• unix-microseconds
• unix-nanoseconds (for respectively number of seconds, milliseconds, microseconds and nanoseconds since start of the Unix epoch); or be written in strftime syntax. If time_format is not set, then the default format is RFC 3339 date-time format, where time-offset = "Z" (e.g. 1985-04-12T23:20:50.52Z).
