Improved technology for managing the caching of objects that are rarely requested by clients. A cache system can be configured to assess a class of objects (such as objects associated with a particular domain) for cacheability, based on traffic observations. If the maximum possible cache offloading for the class of objects falls below a threshold level, which indicates a high proportion of non-cacheable or “single-hitter” content, then cache admission logic is configured to admit objects only after multiple clients requests during a time period (usually the object's time in cache, or eviction age). Otherwise, the cache admission logic may operate to admit objects to the cache after the first client request, assuming the object meets cacheability criteria. The technological improvements disclosed herein can be used to improve cache utilization, for example by preventing single-hitter objects from pushing out multi-hit objects (the objects that get hits after being added to cache).

A database protection system (DPS) detects anomalies in real time without reliance on discrete security rules, instead relying on a machine learning-based approach. In particular, a Bayesian machine learning model is trained on a set of database protocol metadata (DPM) that the system collects during its runtime operation. Typically, a set of DPM parameters is protocol-specific. The approach herein presumes that DPM parameters are not independent, and that their conditional dependencies (as observed from the database connections) can be leveraged for anomaly detection. To that end, the machine learning model is trained to detect dominant (repeating) patterns of connection DPM parameters. Once trained, the model is then instantiated in the DPS and used to facilitate anomaly detection by identifying connections that do not conform to these patterns, i.e. that represent unusual connection DPM parameters.

Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network.

The increasing power density and, therefore, current consumption of high performance integrated circuits (ICs) results in increased challenges in the design of a reliable and efficient on-chip power delivery network. In particular, meeting the stringent on-chip impedance of the IC requires circuit and system techniques to mitigate high frequency noise that results due to resonance between the package inductance and the onchip capacitance.

In addition, there is no added latency to react to power supply noise and there is no degradation to circuit performance as compared to existing techniques in commercial products and literature.

Due diligence of documents is faster and simpler. An electronic mortgage application, for example, often contains or references a collection of many separate electronic documents. Electronic data representing an original version of an electronic document and its current version may be hashed to generate digital signatures. Any auditor may then quickly conduct the due diligence by comparing the digital signatures. If the digital signatures match, then the due diligence reveals that the electronic document has not changed since its creation. However, if the digital signatures do not match, then the electronic document has changed since its creation. The auditor may thus flag the electronic document for additional due diligence. Regardless, a result of the due diligence may be incorporated into one or more blockchains.

A system and method for transforming input data in a data graph is structured in such a way that it does not destroy embedded contextual data yet also keeps the number of edges in the data graph sufficiently small in number that computation with respect to the data in the data graph is feasible with existing computational resources on extremely large graph sets. Incoming data is represented as a collection of “cliques” rather than placing each data object into its own node in the graph database. Maintaining the clique structure though the graph build pipeline dramatically reduces the exponential increase in the number of edges in the graph, while also maintaining all of the contextual data presented on the input record.
