and flightDate
to datetime format would possibly assist us carry out date manipulations and extract helpful options resembling yr, month, day, and the distinction in days between searchDate
and flightDate
. These options can discover temporal patterns within the information that may affect the baseFare
.
- Present a immediate like “Convert searchDate and flightDate to datetime format” to view the code and select Add to steps.
Along with information preparation utilizing the chat UI, you should utilize LCNC transforms with the SageMaker Information Wrangler UI to remodel your information. For instance, we use one-hot encoding as a way to transform categorical information into numerical format utilizing the LCNC interface.
- Add the remodel Encode categorical.
- Select One-hot encode for Rework and add the next columns:
startingAirport
,destinationAirport
,fareBasisCode
,segmentsArrivalAirportCode
,segmentsDepartureAirportCode
,segmentsAirlineName
,segmentsAirlineCode
,segmentsEquipmentDescription
, andsegmentsCabinCode
.
You need to use the superior search and filter possibility in SageMaker Canvas to pick out columns which are of String information sort to simplify the method.
Discuss with the SageMaker Canvas weblog for different examples utilizing SageMaker Information Wrangler. For this submit, we simplify our efforts with these two steps, however we encourage you to make use of each chat and transforms so as to add information preparation steps by yourself.
