Abstract: Embodiments of the disclosed technologies are capable of providing engagement feedback for an online system while maintaining user privacy. Embodiments determine one or more user groups. A user group includes users, and a size of the user group is selected to protect user privacy. A user action is received from a user in a first group. The user action includes an interaction with a piece of content. A group action count is updated for the first group based on the user action. The group action count indicates a number of interactions with the piece of content by any of the users in the first group. An estimated number of unique engagements is calculated based on the group action count and the size of the first group. The estimated number of unique engagements is provided to the online system as the engagement feedback for the piece of content.

Abstract: Methods and apparatus are provided for improving the resilience of a network of positioning-unit devices to failure of the reference device that controls the network timebase via timing information in its signal. In certain embodiments a predetermined one of the positioning-unit devices is configured to monitor the reference signal, assess serviceability of that signal and take control of the network if it determines that signal is unserviceable. Continuity of network synchronisation is thereby maintained despite the reference signal being unserviceable. Preferably the predetermined positioning-unit device is configured to obtain information on the reference signal from at least one other positioning-unit device for assessing reference signal serviceability.

Abstract: A method for automatic hotword threshold tuning includes receiving, from a user device executing a first stage hotword detector configured to detect a hotword in streaming audio, audio data characterizing the detected hotword. The method includes processing, using a second stage hotword detector, the audio data to determine whether the hotword is detected by the second stage hotword detector. When the hotword is not detected, the method includes identifying a false acceptance instance at the first stage hotword detector indicating that the first stage hotword detector incorrectly detected the hotword. The method includes determining whether a false acceptance rate satisfies a false acceptance rate threshold based on a number of false acceptance instances within a false acceptance time period. When the false acceptance rate satisfies the false acceptance rate threshold, the method includes adjusting the hotword detection threshold of the first stage hotword detector.
