A method for updating a stable cuckoo filter used for membership testing of data streams, executed by a processor, is described. The method includes the steps of: performing a first hash on a first element to be inserted into the stable cuckoo filter to determine a first candidate bucket; performing a second hash on a fingerprint of the first element to determine a second candidate bucket; selecting a target candidate bucket from a group consisting of the first candidate bucket and the second candidate bucket; inserting the first element into the target candidate bucket; updating the stable cuckoo filter according to one or more of a random update strategy, an insertion failure update strategy, a scanning strategy, a skip scanning update strategy, a blocked design strategy and a local time-sensitive update strategy; and obtaining an updated stable cuckoo filter.

Stable cuckoo filter for data streams

A battery energy storage system (BESS) including: a battery storage configured to store surplus renewable energy; a controller coupled to the battery storage and configured to control charging operations and discharging operations of the battery storage; a generation meter coupled to the controller and configured to measure renewable energy; a renewable energy generator coupled to the generation meter and configured to generate renewable energy; and a standard meter coupled to the controller and configured to measure energy provided by a power grid; wherein the controller is configured to manage energy expenditure of the BESS according to the following steps: initializing a replay buffer configured to store state transition samples; initializing a main net configured to generate a current Q-value; initializing a target net configured to generate a target Q-value; obtaining an environment state of the BESS; and selecting an action based on an &#x3f5;-greedy policy.

BESS aided renewable energy supply using deep reinforcement learning for 5G and beyond

A system for streaming data items of a streaming application via a Vertical Cuckoo Filter (VCF), including: one or more computers communicating with a provider via a network; wherein the one or more computers includes: a processor; and a storage device coupled to the processor, wherein the storage device is configured to store the VCF, an insert module, a lookup module, and a delete module, the VCF includes buckets with one or more slots and includes at least two bitmasks, the insert module is configured to perform an insert operation of a first fingerprint of a first item from the provider on the VCF, the lookup module is configured to perform a lookup operation of a second fingerprint of a second item from the provider on the VCF, the delete module is configured to perform a delete operation of a third fingerprint of a third item from the VCF.
