Abstract: An approach is provided for compression of sparse data for machine learning or equivalent tasks. The approach involves, for instance, receiving data that is binned into a plurality of bins. The data, for instance, represents a spatial surface such as a geographic region. The approach also involves processing the data by applying a compression criterion to classify one or more bins of the plurality of bins as either data-containing bins or empty bins. The approach further involves establishing a space filling curve over the plurality of bins, wherein the space filling curve linearizes the plurality of bins according to a placement order. The approach further involves storing the data-containing bins of the plurality of bins in a compressed data structure based on the placement order of the space filling curve.

Abstract: An approach is provided for providing map independent location-based notifications. The location-based notification platform causes an initiation of at least one spatial event request for one or more location-based notifications. The at least one spatial event request specifies at least one bounded area in which at least one device is located or to arrive. The location-based notification platform in response to the at least one spatial event request, receives at least one spatial polygon. The at least one spatial polygon represents at least one geographic area that is determined based on the at least one bounded area, and the at least one spatial polygon is associated with the one or more location-based notifications or one or more triggers for the one or more location-based notifications. The location-based notification platform then causes an overlay of the at least one spatial polygon on at least one travel network traveled by the at least one device.

Abstract translation: 提供了一种提供地图独立的基于位置的通知的方法。 基于位置的通知平台导致对一个或多个基于位置的通知的至少一个空间事件请求的启动。 至少一个空间事件请求指定至少一个限定区域，其中至少一个设备位于其中或到达。 基于位置的通知平台响应于至少一个空间事件请求，接收至少一个空间多边形。 所述至少一个空间多边形表示至少一个基于所述至少一个有界区域确定的地理区域，并且所述至少一个空间多边形与所述一个或多个基于位置的通知相关联，或者一个或多个触发器 或更多基于位置的通知。 然后，基于位置的通知平台在由至少一个设备行进的至少一个旅行网络上引起至少一个空间多边形的覆盖。
