Abstract: A method includes receiving transform coefficients corresponding to a scaled video input signal, the scaled video input signal including a plurality of spatial layers that include a base layer. The method also includes determining a spatial rate factor based on a sample of frames from the scaled video input signal. The spatial rate factor defines a factor for bit rate allocation at each spatial layer of an encoded bit stream formed from the scaled video input signal. The spatial rate factor is represented by a difference between a rate of bits per transform coefficient of the base layer and an average rate of bits per transform coefficient. The method also includes reducing a distortion for the plurality of spatial layers by allocating a bit rate to each spatial layer based on the spatial rate factor and the sample of frames.

Abstract: In a distributed system, data is shared between three or more electronic devices. The first device generates and signs an object that includes the data. A second device receives the signed object and determines whether the signed object is valid. If valid, the second device will generate a validated signed object and send it to a third device. The third device will validate the object by determining whether the object includes valid signatures of both the first and second devices.

An electronic calendar event comprising event attributes based on the set of event properties is created.

Abstract: A system on a chip may include a plurality of data plane processor cores sharing a common instruction set architecture. At least one of the data plane processor cores is specialized to perform a particular function via extensions to the otherwise common instruction set architecture. Such systems on a chip may have reduced physical complexity, cost, and time-to-market, and may provide improvements in core utilization and reductions in system power consumption.

The first metal layer may be configured to be a touch screen and the second metal layer may be configured to be a near field communication antenna. The first metal layer may be connected to a first integrated circuit chip and the second layer may be connected to a second integrated circuit chip such that the touch sensor and the NFC antenna are on different circuits.

Abstract: Systems and methods are described for providing decentralized access to a user account. The method may include generating, by an electronic device, a public key and a private key for the user account, generating, by the electronic device, a first inner account block of a blockchain for the user account. The first inner account block may include an identifier for the user account, the public key for the user account associated with the electronic device, encrypted data for the user account, and a signature over contents of the first inner account block using the private key for the user account on the electronic device. The method may further include generating a second inner account block of the blockchain, providing, using the identifier associated with the user account, the blockchain to a plurality of other devices, and controlling access to the user account based on portions of the blockchain.

Abstract: Techniques of compressing triangular mesh data involve generating a neighborhood table (i.e., a table) of fixed size that represents a neighborhood of a predicted vertex of a triangle within a triangular mesh for input into a machine-learning (ML) engine. For example, such a neighborhood table as input into a ML engine can output a prediction for a value (e.g., a position) of a vertex. The residual between the prediction and the actual value of the vertex is stored in an array. The data in the array representing the residuals may be compressed and transmitted over a network. Upon receipt by a computer, the array may be decompressed by the computer. Obtaining the actual value involves the receiving computer generating the same neighborhood table, inputting that neighborhood table into the same ML engine to produce the predicted value, and adding the predicted value to the residual from the decompressed file.

In an aspect, a method receiving, for each resource a plurality of resources that are each accessible by a user device, action data describing actions supported by each resource, each action being an action that can be performed by the user device processing the resource; for each resource: determining, from the action data, an action type for each action supported by the resource, determining, from the action data, action parameters for each action supported by the resource, and indexing the action data, action types and action parameters for the resource in an index that is searchable by a search engine.

Abstract: Systems and methods are provided for operating a pair of earbuds based whether the earbuds are being worn by the same user or different users. In this regard, one or more processors may determine, based on sensor signals from the pair of earbuds, whether the pair of earbuds are being worn by a same user or different users. Based on determining that the pair of earbuds are being worn by the same user, the pair of earbuds may be operated in a first mode so that one or more functions are controlled based on a first set of input settings. Based on determining that the pair of earbuds are being worn by different users, the pair of earbuds may be operated in a second mode so that the one or more functions of the pair of earbuds are controlled based on a second set of input settings.

Abstract: The subject matter of this specification can be embodied in, among other things, a method that receives at a server a first request to rebroadcast a first sponsored content item that was displayed on the social network to the first user to a second user. A second request to display at least one sponsored content item to the second user when the second user accesses an electronic document associated with the social network is received at the server. The first sponsored content item is retrieved for rebroadcast from one or more sponsored content items indicated for rebroadcast to the second user. The first sponsored content item is output to the second user of the social network in response to the second request to display and without requiring the second user to select the first sponsored content item for display.

Abstract: The subject matter described herein provides systems and techniques to counter a high write amplification in physical memory, to ensure the longevity of the physical memory, and to ensure that the physical memory wears in a more uniform manner. In this regard, aspects of this disclosure include the design of a Flash Translation Layer (FTL), which may manage logical to physical mapping of data within the physical memory. In particular, the FTL may be designed with a mapping algorithm, which uses reinforcement learning (RL) to optimize data mapping within the physical memory. The RL technique may use a Bellman equation with q-learning that may rely on a table being updated with entries that take into account at least one of a state, an action, a reward, or a policy. The RL technique may also make use a deep neural network to predict particular values of the table.
