Abstract: Systems, methods, and non-transitory computer-readable media can determine a set of candidate values for a field in a page. The set of candidate values can be evaluated for accuracy based at least in part on a machine learning model, wherein the machine learning model outputs a respective score for each candidate value that measures an accuracy of the candidate value for the field in the page. A best scoring candidate value can be determined from the set of candidate values. The field in the page can be associated with the best scoring candidate value.

Abstract: A system for performing auto-tiering is disclosed. The system may include a plurality of storage devices offering a plurality of resources and organized into storage tiers. The storage devices may store data for virtual machines. A receiver may receive I/O commands and performance data for the virtual machines. A transmitter may transmit responses to the I/O commands. An auto-tiering controller may select storage tiers to store the data for the virtual machines and may migrate data between storage tiers responsive to the performance data. The selection of the storage tiers may optimize the performance of all virtual machines across all storage tiers, factoring the change in performance of the virtual machines and a migration cost to migrate data between storage tiers.

Abstract: A social networking system allows its users to provide metadata for association with objects maintained by the social networking system. Some of the metadata may be presented to other users along with the object. To prevent association of inaccurate metadata with an object, the social networking system determines a confidence value associated with a user who provided metadata for association with an object. The confidence value indicates of the accuracy of metadata provided by the user relative to information associated with the object. If the user has previously provided less than a threshold amount of metadata to associate with objects, the confidence score is determined using characteristics associated with the user by the social networking system. The metadata provided by the user is stored but not associated with the object if the user's confidence value is less than a threshold value.

Abstract: An electrical connector for connecting to ground and first and second signal lines includes a ground contact, a first signal contact, a second signal contact, and a switch connected to the first signal contact and the ground contact. The switch is biased “on” until after the first signal contact is connected to the first signal line, the ground contact is connected to the ground, and the second signal contact is connected to the second signal line. The switch, during connection of the connector to ground and first and second signal lines, is thereby automatically triggered to “off” during connection of the connector. If the first and second signal lines are differential signals, the switch, instead, electrically connects and disconnects the first signal contact to the second signal contact.
