Abstract: Techniques performed by a data processing system for reconstructing a three-dimensional (3D) model of the face of a human subject herein include obtaining source data comprising a two-dimensional (2D) image, three-dimensional (3D) image, or depth information representing a face of a human subject.

The coarse 3D model may be a 3D Morphable Model (3DMM), and the coarse 3D model may be refined through free-form deformation in which the deformation of the mesh is limited by applying an as-rigid-as-possible (ARAP) deformation constraint.

Abstract: A computer-implemented technique is described for enabling a user to create a conversational bookmark in the course of the user's interaction with a BOT. The bookmark designates a particular juncture in the user's interaction with the BOT.

The technique can also be extended to a task of creating and activating bookmarks in the course of a conversation among two or more humans.

Abstract: Systems and methods are taught for providing customers of a cloud computing service to control when updates affect the services provided to the customers. Because multiple customers share the cloud's infrastructure, each customer may have conflicting preferences for when an update and associated downtime occurs.

Additionally, the schedule for the update may be transmitted to customers so that they can prepare for the downtime of services associated with the update.

Abstract: Connection settings used by a mobile device to connect to a packet data network, e.g. the internet, are stored in a subscriber identity module (SIM) card. This enables connection settings to be pre-loaded on a SIM card, allowing a mobile device to immediately connect to the internet without manual configuration. The mobile device's connection settings may also be updated by a mobile network operator via an over the air profile update. For example, the operator may supply a device with connection settings the first time it connects to the network. Connection settings may be stored in one or more files within the SIM profile, and may be updated via a remote file management operation. Embedded-SIM (eSIM) profiles may also store connection settings in profile metadata, which may be updated via a metadata update operation.

Abstract: An exemplary computing environment having a DNN module can maintain one or more bandwidth throttling mechanisms. Illustratively, a first throttling mechanism can specify the number of cycles to wait between transactions on a cooperating fabric component (e.g., data bus). Illustratively, a second throttling mechanism can be a transaction count limiter that operatively sets a threshold of a number of transactions to be processed during a given transaction sequence and limits the number of transactions such as multiple transactions in flight to not exceed the set threshold. In an illustrative operation, in executing these two exemplary calculated throttling parameters, the average bandwidth usage and the peak bandwidth usage can be limited. Operatively, with this fabric bandwidth control, the processing units of the DNN are optimized to process data across each transaction cycle resulting in enhanced processing and lower power consumption.

Abstract: A proxy server intercepts a message, including a script, from a back-end component of an application, wherein the message is directed to a front-end component of the application executing on a client computing device. The proxy server identifies code in the script that can prompt a download event of a client-side generated content at the client computing device without having to communicate with the back-end component of the application. The proxy server modifies the identified code to cause the front-end component of the application to execute a custom code component for inspecting a download event prompted by the identified code in place of executing the identified code, thereby generating a modified script which is passed to the client computing device. Additionally, the client computing device executes the custom code component configured to inspect the code to determine if the code will prompt the download event of the client-side generated content.

The audio interface further allows the user to verbally request actions for the messages.

Abstract: A method of mapping symbols of a physical control format indicator channel (PCFICH) is described. A start position of a resource element to map the symbols for the PCFICH is determined by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink. The symbols are mapped in the start position. Therefore, a problem of wasting resource elements or not being able to implement mapping can be solved by applying a simple mapping rule while mapping symbols of the PCFICH.
