This field shows the impact of leading days (days before the event), lagging days (days after an event), and the days the event occurs. For example, if someone is taking a flight to a location to attend a concert, they are typically not going to be arriving on the day of the event. They will often arrive a couple of days before and check into their hotel before the concert begins. The Predicted Impact Patterns for accommodation reflects the fact that this demand will be felt before the event starts and often after it ends. Impact patterns are industry-specific and reflect the varying leading and lagging impact of events on different industries.
We recommend that if you operate in the supported industries you use demand impact features instead of the generic features as these will result in greater forecast accuracy as they include the impact before an event starts and after it finishes. In our testing we have found significant forecasting accuracy improvements from using impact pattern features in demand forecast machine learning models.
Below is a visual representation of impact patterns:
You can use Predicted Impact Patterns in your demand forecasting so that your machine learning models will take account of the impact on leading and lagging days. In our testing we have found using impact patterns increases forecasting accuracy.
Impact Patterns are available for the following industry segments and categories:
phq_rank
public-holidays
observances
phq_attendance
community
concerts
conferences
expos
festivals
performing-arts
sports
impact_patterns is an array of impact pattern objects. The same event can have different impact patterns for different industry verticals. It contains the following fields:
vertical - The industry vertical the impact pattern applies to.
impact_type - Indicates the type of impact shown in the impact pattern. This will apply to either phq_rank or phq_attendance, depending on the vertical.
impacts is an array of objects with one entry for each day that contains the following values:
date_local - the date in the local timezone of the event.
value - the value of the impact_type for that given day. For example, if the impact_type was phq_rank the value would be the PHQ Rank value on the given day. In the case for accommodation or hospitality where the impact_type is phq_attendance, this is what will be presented in this field.
position - can be leading, event_day or lagging. leading are the days before the event occurs, event_day are the days the event occurs, and lagging are the days after the event has occurred.
or for retail for severe weather events
Impact patterns are returned in the response in the impact_patterns field. This shows the Impact Pattern for each event. Below are the details of the data structure of that field.
You can also use Predicted Impact Patterns with the Features API. The features API provides pre-built machine learning features for demand forecasting. See thedocumentation. Use the features for your industry to get more accurate forecasting results. We have a generic feature without impact patterns for sports called phq_attendance_sports but that does not include impact patterns so only shows the impact on the days of the event. In order to use impact patterns with the features API you need to use the impact pattern features. For example, if you are in the accommodation segment and are using the features API to find the impact of sports events on your location you would use phq_attendance_sports_accommodation. If you were in the Hospitality Segment you would use phq_attendance_sports_hospitality.
