Abstract: This document describes techniques and apparatuses for optimizing a cellular network using machine learning. In particular, a resource control module of a user equipment (UE) 110 selects a particular disconnected state 214 based on a power status of the UE 110. If the power status is sufficient to support an inactive state 216, the UE 110 transitions to the inactive state 216 to enable a connection with a base station 120 to be quickly resumed. Alternatively, if the power status is insufficient for the inactive state 216, the UE 110 transitions to the idle state 218 to conserve power. In some cases, the UE 110 dynamically switches between different disconnected states 214 responsive to changes in the power status. By determining a resource control state 210 based on the power status, the UE 110 balances communication responsiveness and power consumption to support mobile operation.

Abstract: The present disclosure discusses systems and methods to mitigate traffic spikes in retrieving secondary content items for display in concurrently streamed content streams. The system can pre-fetch secondary content items for the upcoming secondary content slots. To retrieve an appropriate content item, the system can predict the length of the secondary content slot. The system can use the predicted length of the secondary content slot to distribute the traffic spike over a larger span of time to mitigate the spike.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for pairing a speech-enabled device with a display device. A determination may be made to pair a speech-enabled device with a display device of a particular type. A set of display devices that are associated with the speech-enabled device may be identified in response to determining to pair the speech-enabled device with the display device of the particular type. An instruction may be provided to each of the display devices. The instruction may cause the display device to determine (i) whether the display device is of the particular type and (ii) whether the display device and the speech-enabled device both share a local area network and display on the display device an indication regarding pairing with the speech-enabled device.

Abstract: Systems, devices, and methods for embedding a HOE in an eyeglass lens are described. A method of embedding a HOE in an eyeglass lens includes forming a world-side portion of the eyeglass lens, forming an eye-side portion of the eyeglass lens, physically coupling the eye-side portion of the eyeglass lens to the HOE with a low-temperature optically clear adhesive (“LT-OCA”), and physically coupling the world-side portion of the eyeglass lens to the HOE with LT-OCA. Forming the lens portions may include high-temperature processes, and the HOE may not be damaged by the high-temperature processes since the high-temperature processes may be performed on the lens portions prior to coupling the lens portions to the HOE.

Abstract: Methods, systems, and apparatus, including an apparatus for transferring data using multiple buffers, including multiple memories and one or more processing units configured to determine buffer memory addresses for a sequence of data elements stored in a first data storage location that are being transferred to a second data storage location. For each group of one or more of the data elements in the sequence, a value of a buffer assignment element that can be switched between multiple values each corresponding to a different one of the memories is identified. A buffer memory address for the group of one or more data elements is determined based on the value of the buffer assignment element. The value of the buffer assignment element is switched prior to determining the buffer memory address for a subsequent group of one or more data elements of the sequence of data elements.

Abstract: A method of presenting information to a party through a messaging application is described. Responsive to receipt of a communication from a party (e.g., the first user), a reply is sent. The communication and the reply is presented in an interface to the sender. The messaging system determines matching content that is relevant to one or both of the communication and the reply and determines a quality of the match. Determining the quality of the match may include determining a score for an advertisement based on the advertisement's responsiveness to content identified in the reply message that was sent. Based on a determination that the quality is above a threshold, the matching content is presented along with the communication and the reply.

Abstract: A sign value of a DC coefficient of a current block is determined using neighbor blocks of the current block. First and second sign values are identified as respectively corresponding to an above neighbor block of the current block and a left neighbor block of the current block. A context value is calculated by applying a first weighting value to the first sign value and a second weighting value to the second sign value. The first weighting value is based on a boundary between the above neighbor block and the current block, and the second weighting value is based on a boundary between the left neighbor block and the current block. A probability value is selected based on the context value. The sign value of the DC coefficient of the current block is then determined using the probability model.
