Perceptual statistics are used to compute importance maps that indicate which regions of a video frame are important to the human visual system. Importance maps may be generated from encoders that produce motion vectors and employ motion estimation for inter-prediction. The temporal contrast sensitivity function (TCSF) may be computed from the encoder's motion vectors. Quality metrics may be used to construct a true motion vector map (TMVM), which refines the TCSF. Spatial complexity maps (SCMs) can be calculated from simple metrics (e.g. block variance, block luminance, SSIM, and edge detection). Importance maps with TCSF, TMVM, and SCM may be used to modify the standard rate-distortion optimization criterion for selecting the optimum encoding solution. Importance maps may modify encoder quantization. The spatial information for the importance maps may be provided by a lookup table based on block variance, where negative and positive spatial QP offsets for block variances are provided. |

Embodiments of the present invention relate to identifying website visitors. Initially, a predictor is trained with a set of data of known website visitors to identify a rule with the highest effectiveness score. To do so, each rule in a set of rules is applied to all cookies in the set of data. Based on a selected goal of identifying unknown website visitors, the rule with the highest effectiveness score is identified. To identify a cookie of an unknown website visitor, a cookie representation corresponding to the cookie is identified. The cookie representation represents the cookie in a numeric vector space and can computed based on hits in log data and a selection of variables. Utilizing the cookie representation, a cookie-stitching rule is selected and applied to the cookie. In this way, a website visitor associated with the cookie can be identified. |

System and method for using VoLTE session continuity information using logical scalable units
Logical scalable units (LSU) can be used within a single network data center to provide stateful scalability. However, LSUs are not suitable for operating across multiple network data centers in order to provide geographical redundancy in active-active scenarios while providing high availability. This is because the latencies associated with replicating full session information are unacceptably slow. An additional component in the LSU (known as an LSU Frontend) can be used to replicate a small subset of session information between LSUs. This subset of session information may be enough to enable LSUs to process requests in an acceptable way rather than outright failing. This may be particularly advantageous in scenarios where the requests relate to Voice over LTE calls, because outright failure is very perceivable to subscribers, and it causes resource leakage within the telecommunications network. |

Auto-tuning program analysis tools based on user feedback
User-guided machine learning (ML) significantly reduces false alarms generated by an automated analysis tool performing static security analysis. User interactivity involves initial review and annotation of findings (“witnesses”) in a report generated by the analysis tool. Those annotated findings are then used by the system to generate a “hypothesis” about how to further classify the static analysis findings in the report. The hypothesis is implemented as a machine learning classifier. To generate the classifier, a set of features are abstracted from a typical witness, and the system compares feature sets against one another to determine a set of weights for the classifier. The initial hypothesis is then validated against a second set of user-annotated findings, and the classifier is adjusted as necessary based on how close it fits the new data. Once the approach converges on a final classifier, it is used to filter remaining findings in the report. |

The power bank device is operable in a discharging mode in which the battery cells power the DC-to-DC converter, and the converter drives a regulated DC voltage onto the output connector. The detection circuitry detects whether a light load condition exists in which only a small amount of current is being output onto the output connector. If the condition is detected, then the converter is disabled so that current flow out of the output connector is stopped. In one example, the condition is detected by supplying a constant current onto the output connector and detecting whether the voltage on the output connector rises and stays above a predetermined voltage for a predetermined amount of time. |

Tool employing homotopy-based approaches in finding the controlling unstable equilibrium point in the electric power grid
The analysis tool employs a computer-implemented algorithm that uses homotopy-based approaches to map the solution from the exit point to the controlling unstable equilibrium point (UEP). The computational time is reduced significantly by using an approximate exit point rather than computing an accurate exit point as it is required in finding the controlling UEPs using traditional transient stability direct methods. In addition, this method eliminates the necessity of computing the minimum gradient point (MGP) which is a key element in using Newton methods. These properties provide an advantage to homotopy-based approaches over traditional iterative methods in terms of both speed of computation and reliability of finding solutions. |
