    摘要： Searching online catalog databases by shoppers is improved by performing similarity searching on searches performed by the shopper, in conjunction with adjusting the similarity metric used during the search to interactively improve the relevance of the resulting search results to the shopper. This involves using relevance feedback and/or product redefinition to learn the “implied concept” of the shopper's stated product requirements; that is, the quality of the search results is enhanced through understanding the concept implied by the shopper's queries by, for example, learning from the product results marked as “relevant” or “irrelevant” by the shopper. This approach is in contrast with attempts to enhance search results using, for example, the shopper's past orders or previous actions, or the past orders or previous actions of other shoppers who may have a purchase history similar to that of the current shopper.

    摘要翻译： 通过对购物者执行的搜索执行相似性搜索，结合调整搜索期间使用的相似性度量来交互地提高所得到的搜索结果与购物者的相关性，从而改善了购物者对在线目录数据库的搜索。 这涉及使用相关性反馈和/或产品重新定义来了解购物者声明的产品要求的“隐含概念”; 也就是说，通过了解购物者查询所隐含的概念，例如从购物者标识为“相关”或“无关”的产品结果中学习，可以提高搜索结果的质量。 这种方法与使用例如购物者的过去订单或先前操作或其他可能具有与当前购物者的购买历史相似的购买历史的其他购物者的过去订单或之前的动作来增强搜索结果形成对比。

    摘要： A method and apparatus for hardware efficient decoding of compression coefficients. In one embodiment, a numerator of an equation used to compute a compression coefficient is computed. The denominator is also computed. The numerator and denominator values are truncated such that each numerator and denominator are equal in length to a predetermined constant K. A K-bit integer division is then executed to determine the value of the compression constant.

    摘要： A method, apparatus, and article of manufacture for restoring a deteriorated signal to an undeteriorated signal. A deteriorated signal consists of a plurality of deteriorated and undeteriorated data points. For each deteriorated data point, a plurality of class types is created based upon characteristics of the area containing the deteriorated data point. The data point is classified with respect to one of the plurality of class types and assigned a corresponding input signal class. The undeteriorated signal is generated by adaptively filtering the deteriorated input signal in accordance with the input signal classification result. More than one classification method is used to create the plurality of class types. Created classes may include a motion class, an error class, a spatial class or a spatial activity class.

    摘要： A system and method for source coding a signal to localize transmission errors to a set of samples is disclosed. The signal comprises a plurality of signal elements (SEs) with each SE having a plurality of components. The signal is divided into a plurality of data sets with each data set having a set of SEs. Each SE component of a data set is grouped into a plurality of divisions with each SE component having a plurality of bits. The plurality of bits of the SE components are distributed from the plurality of divisions across a generated bitstream. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.

    摘要： Provided are methods, apparatus arid computer programs for scheduling storage input and/or output (I/O) requests. A method for scheduling storage access requests determines a request processing sequence calculated to maximize SLA-based revenues achievable from processing a number of requests. A storage controller includes a scheduler which implements a revenue-based scheduling function to determine a revenue-maximizing processing sequence, and then assigns storage access requests to locations in a queue corresponding to the determined sequence. In an on-line mode, the scheduler can adapt to additional received requests, evaluating the revenue function for the additional requests and modifying the schedule if required. The method may include analyzing a request stream to predict requests that are likely to be received in the near future, and taking account of the predicted requests when determining a processing schedule.
