Abstract: An online system actively and randomly selects content items to be labeled for training a classifier. An online system receives content items from client devices of users and selects sets of the content items to be labeled by human labelers. The randomly selected content items are selected at random from the received content items, and the actively selected content items are selected based on the classifier's confidence in accurately predicting the classification of the content items. The online system may use a histogram of content items to actively select content items. The online system assigns the content items to bins of the histogram based on priority scores and selects content items with priority scores of the highest percentile. The online system provides the selected content items to human labelers for labeling. The labeled content items are then used for training the classifier.

Abstract: An online system determines that a mobile device of a user and content device are connected to the same local network. To determine whether the content device is associated with the user, the online system provides a token and network ports to the content device. The content device establishes a connection to the mobile device using a selected network port to send the token. Responsive to receiving the token from the mobile device, the online system determines that the devices are connected to the same local network. The online system may also determine that the devices are within physical proximity to each other. The online system may send content items to the devices, and the user may view or interact with the content items simultaneously on multiple devices. Thus, the mobile device or content device acts as a complementary “second screen” or “control device” for the other device.

Abstract: A deformation sensing apparatus comprises a transmitter coupled to a propagation channel, and a receiver coupled to the same first end of the propagation channel. The propagation channel of the deformation is a transmission line, where a signal is transmitted by the transmitter and reflected signals are measured by the receiver responsive to the transmitted signals. A bend in the propagation channel results in a change in impedance of the transmission line at a location of the bend, resulting in a reflection of the signal from the location of the bend. The time delay of the reflected signals corresponds to the distance along the length of the channel where a bending of the propagation channel occurs. The amplitude of the reflected signal corresponds to a bend angle.

Abstract: To address privacy issues with “always on” cameras of an AR headset, the cameras can be muted and content displayed by the headset adjusted to provide a user with a visual indication that the cameras are deactivated. The headset includes a display element configured to display content to a user and an eye tracking system that includes a camera configured to track eye motion of the user. In response to the headset receiving a camera muting event from the user or the external environment, the headset deactivates the camera and adjusts the content displayed on the display element to provide the user with a visual indication that the camera is deactivated. In one embodiment, the visual indication is an adjustment of the display from a default RGB color mode to “monochrome” or other predefined color map.

Abstract: A video generation system is described that extracts one or more characters or other objects from a video, re-animates the character, and generates a new video in which the extracted characters. The system enables the extracted character(s) to be positioned and controlled within a new background scene different from the original background scene of the source video. In one example, the video generation system comprises a pose prediction neural network having a pose model trained with (i) a set of character pose training images extracted from an input video of the character and (ii) a simulated motion control signal generated from the input video. In operation, the pose prediction neural network generates, in response to a motion control input from a user, a sequence of images representing poses of a character. A frame generation neural network generates output video frames that render the character within a scene.
