Abstract: In an illustrative embodiment, an automated system determines similarities between properties at a location using customized features sets. The system can generate feature sets for properties from property attribute data received from external and internal sources. The system can transform one or more elements of attribute data of combined internal and external data into customized property attributes that enhance property attribute comparisons. The combined attribute data can be applied to a machine learning algorithm that identifies a portion of the combined attribute data for using in property similarity calculations. Using the identified features, the system can calculate similarity scores identifying an amount of similarity between properties at the location and a property identified in a comparable property query, which can be output to an external device.

Abstract: A computer-implemented method includes determining a quantity of reserved resources that need to be reserved in one node. Nodes in which quantities of current remaining resources are less than a quantity of reserved resources are determined. For each determined node, calculating a total quantity of resources occupied by allocated service requests in the node and determining whether the node is capable of satisfying the quantity of reserved resources. If yes, marking the node as a migratable node. One migrating node is selected from migratable nodes and corresponding M allocated service requests are migrated to at least one other node. Resources occupied by the M allocated service requests are released, where M satisfies a condition that after the resources occupied by the M allocated service requests are released, a quantity of remaining resources in the migrating node is not less than the quantity of reserved resources.
