Abstract: A clustering system provides bounded incremental clustering for adding input data instances to existing data clusters. Input data instances are received and processed to form input data clusters. For a given input data cluster, a subset of existing data clusters is selected, and a subset of existing data instances are selected from each of the selected existing data clusters. The selected existing data instances and the input data instances from the given input data cluster are processed to form intermediate clusters. At least one intermediate cluster is mapped to an existing data cluster.

Abstract: Techniques are disclosed for incremental agglomerative clustering of data, including but not limited to digital image data. Fewer than all of a plurality of existing digital image fingerprints are sampled from a first hierarchical data cluster of digital image fingerprints stored in a data storage device, the first hierarchical data cluster excluding a new digital image fingerprint. The new digital image fingerprint and the existing digital image fingerprints sampled from the first hierarchical data cluster are clustered to produce a second hierarchical data cluster of digital image fingerprints, the second hierarchical data cluster including the new digital image fingerprint. If a majority of the existing digital image fingerprints in the first hierarchical data cluster match the new digital image fingerprint, then the second hierarchical data cluster is mapped to the first hierarchical data cluster based on the determination.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media for selecting representative recent cover images from collections of digital portraits by determining selection scores based on average face vectors. For example, the disclosed systems can generate an average face feature vector to represent a common appearance or facial expression of a user in the collection of digital portraits. The disclosed systems can further determine representativeness scores that indicate measures of closeness of digital portraits to the average face feature vectors. In addition, the digital portrait selection system can determine various other factors, such as recency scores, face area scores, and face expandability scores. Based on these factors, the digital portrait selection system can determine an overall selection score and select a digital portrait as a cover image.

Abstract: Described herein are aspects related to assigning primary channels in wireless communications. An amount of available bandwidth within a radio frequency band can be determined for shared access by a plurality of operators, where each operator operates a radio access network having one of a plurality of radio communication compatibility types, and where each radio communication compatibility type defines a set of one or more compatible radio access technologies. The amount of available bandwidth can be allocated into radio compatibility type-specific bandwidth partitions for each radio communication compatibility type based on a number of the plurality of radio communication compatibility types and a number of the plurality of operators corresponding to each radio communication compatibility type. A primary channel can be assigned within at least one of the radio compatibility type-specific bandwidth partitions to at least one operator of the number of the plurality of operators.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Applying the one or more filters may include applying an UL RSSI filter to the one or more femto nodes to determine whether presence of the device causes a rise in UL RSSI measured at the one or more femto nodes.

Abstract: Techniques for mobility-aware contention procedures on a shared communication medium are disclosed. A connection failure associated with mobility between a source access point and a target access point sharing a communication medium may be detected. Based on the detected connection failure, a backoff threshold associated with contention-based access to the communication medium may be adapted. Contention for access to the communication medium may then proceed in accordance with the adapted backoff threshold.

Abstract: Aspects of the present disclosure relate to methods and apparatus for allocating (or assigning) channels to different groups of wireless nodes in the case of co-channel coexistence between the different groups and interference to one or more other wireless nodes. One example method generally includes evaluating, for different assignments of channels to different groups of wireless devices that share bandwidth, an amount of transmission limitation imposed due to higher-tier protection, and assigning one or more of the channels to each of the groups, based on the evaluation.

Abstract: Systems and methods for handling undesirable inter-frequency cell changes are disclosed. A small cell base station receives a request to perform a cell change of a user equipment (UE) from a base station serving the UE to the small cell base station, wherein the base station serving the UE is operating on a different frequency than the small cell base station, receives, from the base station, parameters related to one or more previous cell changes performed by the UE, and determines whether or not the cell change is desirable based on the parameters related to the one or more previous cell changes.

Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

Abstract: A digital camera is configured to display a continually updated preview image of an observed scene, wherein kinetic objects that appear in the observed scene do not appear in the continually updated preview image. An observed scene includes static objects and kinetic objects. The observed scene is recorded using a digital imaging sensor which forms part of a smartphone. A live camera feed results, the live camera feed comprising a plurality of frames, each depicting the observed scene at a specific time. A median color value is evaluated over m non-consecutive frames captured from the live camera feed. The median color values are used to generate an output feed that is displayed at a reduced frame rate as compared to the live camera feed. The resulting displayed scene includes the same static objects which appeared in the observed scene, but does not include the kinetic objects.
