摘要： To support encoding a control circuit determines a primary prediction mode to employ when encoding a block of video data and then determines a corresponding companion prediction mode to correspond to the primary prediction mode. The control circuit can then generate a mixed prediction for the block of video data by mixing a prediction formed using the primary prediction mode with a prediction formed using the companion prediction mode. By one approach the control circuit determines the corresponding companion prediction mode by accessing a companion prediction mode lookup table. In such a case, if desired, upon generating the mixed prediction for the block of video data the control circuit can also automatically update the companion prediction mode lookup table. By one approach a corresponding decoder infers the employed companion prediction mode (or modes).

摘要： At least one microphone is incorporated in a gaming machine along with voice recognition/analysis software that analyzes the quality of the player's voice to determine the player's age, gender, emotions, and other attributes. Such voice attributes are not direct voice commands by the player, but are voice characteristics that provide information about the player herself. After the player is characterized based on her voice attributes, game software is modified accordingly so that the game is customized for the particular player. For example, the detection that the player is a young woman may cause the game to use a certain theme involving young female characters, trendy modern music, etc. The game also adapts to the detected voiced emotions of the player. Other features of the machine cause there to be verbal interaction between the player and the machine, enhancing the playing experience.
摘要翻译：至少一个麦克风与语音识别/分析软件一起并入游戏机中，该软件分析玩家的声音的质量以确定玩家的年龄，性别，情绪和其他属性。这样的语音属性不是播放器的直接语音命令，而是提供关于玩家本身的信息的语音特征。在基于她的声音属性对播放器进行了特征描述之后，相应地修改游戏软件，以便为特定玩家定制游戏。例如，玩家是年轻女子的检测可能导致游戏使用涉及年轻女性角色，时尚现代音乐等的某些主题。游戏还适应于玩家的检测到的有声情绪。机器的其他功能导致播放器和机器之间的语言交互，增强了播放体验。

摘要： A method for correcting long-term phase drift of a crystal oscillator in a numerically- controlled oscillator is described. The method includes determining the phase error in an oscillator signal in comparison with an external time base; delta-sigma modulating the phase error to generate a delta-sigma error bitstream; conditionally adding or subtracting an error correction step size from a phase increment value in each clock cycle based on the delta-sigma error bitstream, to create a modulated phase increment value; and adding the modulated phase increment value to a phase accumulator to generate an error-corrected output digital signal. The delta-sigma-based error correction method avoids the use of multipliers. The same delta-sigma error signal can be used in multiple numerically-controlled oscillators configured to different output frequency if driven by the same reference oscillator.

摘要： Methods of encoding and decoding sign information for non-zero coefficients in a block of video with transform skipped. The methods include context-based coding of a flag that signals if all signs are the same in the block; using a finite state machine to determine contexts for coding of sign information, some of which may be context-based coded and some of which may be non-context-based coded; context-based coding of sign information wherein the context is based upon the signs of neighbouring coefficients; context-based coding of sign information, where the sign information is a prediction of the sign; and using a dedicated context to code signs with a sign flag indicating whether signs in a transform skipping block have been inverted to preserve a dominant sign bias.

摘要： A model training system protects data leakage of private data in a federated learning environment by training a private model in conjunction with a proxy model. The proxy model is trained with protections for the private data and may be shared with other participants. Proxy models from other participants are used to train the private model, enabling the private model to benefit from parameters based on other models' private data without privacy leakage. The proxy model may be trained with a differentially private algorithm that quantifies a privacy cost for the proxy model, enabling a participant to measure the potential exposure of private data and drop out. Iterations may include training the proxy and private models and then mixing the proxy models with other participants. The mixing may include updating and applying a bias to account for the weights of other participants in the received proxy models.

摘要： An object detection model and relationship prediction model are jointly trained with parameters that may be updated through a joint backbone. The offset detection model predicts object locations based on keypoint detection, such as a heatmap local peak, enabling disambiguation of objects. The relationship prediction model may predict a relationship between detected objects and be trained with a joint loss with the object detection model. The loss may include terms for object connectedness and model confidence, enabling training to focus first on highly-connected objects and later on lower-confidence items.

摘要： A model visualization system analyzes model behavior to identify clusters of data instances with similar behavior. For a selected feature, data instances are modified to set the selected feature to different values evaluated by a model to determine corresponding model outputs. The feature values and outputs may be visualized in an instance-feature variation plot. The instance-feature variation plots for the different data instances may be clustered to identify latent differences in behavior of the model with respect to different data instances when varying the selected feature. The number of clusters for the clustering may be automatically determined, and the clusters may be further explored by identifying another feature which may explain the different behavior of the model for the clusters, or by identifying outlier data instances in the clusters.
