Abstract: Various embodiments relate to systems including a surveillance unit. A system may include a surveillance unit comprising at least one camera for capturing data including one or more objects. The surveillance unit may also include a first model for generating at least one vector representation based on the one or more objects of the captured data. The system may also include a server communicatively coupled to the surveillance unit including a second model to receive the at least one vector representation and generate output data based on the at least one vector representation. The surveillance unit may further be configured to receive the output data and convey, via at least one output device, an output based on the output data. Associated methods are also disclosed.

Abstract: The present disclosure describes systems, methods, and non-transitory computer readable media for generating lookalike segments corresponding to a target segment using decision trees and providing a graphical user interface comprising nodes representing such lookalike segments. Upon receiving an indication of a target segment, for instance, the disclosed systems can generate a lookalike segment from a set of users by partitioning the set of users according to one or more dimensions based on probabilities of subsets of users matching the target segment. By partitioning subsets of users within a node tree, the disclosed systems can identify different subsets of users partitioned according to different dimensions from the set of users. The disclosed systems can further provide a node tree interface comprising a node for the set of users and nodes for subsets of users within one or more lookalike segments.
