    • Providing content based cache for graphic resource management is disclosed herein. In some aspects, a portion of a shadow copy of graphics resources is updated from an original copy of the graphics resources when a requested resource is not current. The shadow copy may be dedicated to a graphics processing unit (GPU) while the original copy may be maintained by a central processing unit (CPU). In further aspects, the requested graphics resource in the shadow copy may be compared to a corresponding graphics resource in the original copy when the GPU requests the graphics resource. The comparison may be performed by comparing hashes of each graphics resource and/or by comparing at least a portion of the graphics resources.
    • 本文公开了提供用于图形资源管理的基于内容的缓存。 在一些方面,当所请求的资源不是当前时,图形资源的卷影副本的一部分从图形资源的原始副本被更新。 影子副本可以专用于图形处理单元(GPU),而原始副本可以由中央处理单元(CPU)维护。 在另外的方面,当GPU请求图形资源时,可将影子副本中所请求的图形资源与原始副本中的对应图形资源进行比较。 可以通过比较每个图形资源的哈希和/或通过比较图形资源的至少一部分来执行比较。

    • A speech recognition system described herein includes a receiver component that receives a distorted speech utterance. The speech recognition also includes an updater component that is in communication with a first model and a second model, wherein the updater component automatically updates parameters of the second model based at least in part upon joint estimates of additive and convolutive distortions output by the first model, wherein the joint estimates of additive and convolutive distortions are estimates of distortions based on a phase-sensitive model in the speech utterance received by the receiver component. Further, distortions other than additive and convolutive distortions, including other stationary and nonstationary sources, can also be estimated used to update the parameters of the second model.

    • Described is a calibration model for use in a speech recognition system. The calibration model adjusts the confidence scores output by a speech recognition engine to thereby provide an improved calibrated confidence score for use by an application. The calibration model is one that has been trained for a specific usage scenario, e.g., for that application, based upon a calibration training set obtained from a previous similar/corresponding usage scenario or scenarios. Different calibration models may be used with different usage scenarios, e.g., during different conditions. The calibration model may comprise a maximum entropy classifier with distribution constraints, trained with continuous raw confidence scores and multi-valued word tokens, and/or other distributions and extracted features.
    • 描述了一种用于语音识别系统的校准模型。 校准模型调整由语音识别引擎输出的置信度得分,从而为应用程序提供改进的校准置信度得分。 基于从先前的相似/相应的使用情景或情景获得的校准训练集,校准模型是针对特定使用场景(例如针对该应用)进行训练的模型。 不同的校准模型可以用于不同的使用场合,例如在不同的条件下。 校准模型可以包括具有分布约束的最大熵分类器,训练有连续原始置信分数和多值词令牌,和/或其他分布和提取的特征。

    • Techniques and systems for training an acoustic model are described. In an embodiment, a technique for training an acoustic model includes dividing a corpus of training data that includes transcription errors into N parts, and on each part, decoding an utterance with an incremental acoustic model and an incremental language model to produce a decoded transcription. The technique may further include inserting silence between a pair of words into the decoded transcription and aligning an original transcription corresponding to the utterance with the decoded transcription according to time for each part. The technique may further include selecting a segment from the utterance having at least Q contiguous matching aligned words, and training the incremental acoustic model with the selected segment. The trained incremental acoustic model may then be used on a subsequent part of the training data. Other embodiments are described and claimed.
