摘要： Apparatus and methods for efficient synaptic update in a network such as a spiking neural network. In one embodiment, the post-synaptic updates, in response to generation of a post-synaptic pulse by a post-synaptic unit, are delayed until a subsequent pre-synaptic pulse is received by the unit. Pre-synaptic updates are performed first following by the post-synaptic update, thus ensuring synaptic connection status is up-to-date. The delay update mechanism is used in conjunction with system “flush” events in order to ensure accurate network operation, and prevent loss of information under a variety of pre-synaptic and post-synaptic unit firing rates. A large network partition mechanism is used in one variant with network processing apparatus in order to enable processing of network signals in a limited functionality embedded hardware environment.
摘要翻译：用于在诸如尖峰神经网络的网络中有效突触更新的装置和方法。在一个实施例中，响应于由突触后单元产生后突触脉冲的突触后更新被延迟，直到该单元接收到后续的突触前脉冲。先突触后更新是在突触后更新之后进行的，因此确保突触连接状态是最新的。延迟更新机制与系统“刷新”事件结合使用，以确保网络运行准确，防止各种突触前和突触后单位发射速率下的信息丢失。在一个变型中，网络分割机制用于网络处理设备，以便能够在有限的功能嵌入式硬件环境中处理网络信号。

摘要： Techniques are provided for automatic sampling evaluation. An automatic sampling evaluation system enables users to evaluate convergence of one or more search processes. For example, given a set of searches that were validated by human review, a system can implement a retrieval process that samples one or more non-retrieved collections. Each individual document's similarity in the one or more non-retrieved collections is automatically evaluated to other documents in any retrieved sets. Given a goal of achieving a high recall, documents with high similarity can then be analyzed for additional noun phrases that may be used for a next iteration of a search. Convergence can be expected if the information gain in the new feedback loop is less than previous iterations, and if the additional documents identified are below a certain threshold document count.
摘要翻译：提供了自动抽样评估技术。自动抽样评估系统使用户能够评估一个或多个搜索过程的收敛。例如，给定通过人工审查验证的一组搜索，系统可以实现对一个或多个未检索的集合进行抽样的检索过程。一个或多个未检索的集合中的每个单独文档的相似性自动地被评估为任何检索集合中的其他文档。鉴于实现高回调的目标，可以分析具有高相似性的文档，以获得可用于下一次搜索迭代的其他名词短语。如果新反馈循环中的信息增益小于先前的迭代，并且如果所标识的附加文档低于某个阈值文档计数，则可以预期收敛。

摘要： In various embodiments, a semantic space associated with a corpus of electronically stored information (ESI) may be created and used for concept searches. Documents (and any other objects in the ESI, in general) may be represented as vectors in the semantic space. Vectors may correspond to identifiers, such as, for example, indexed terms. The semantic space for a corpus of ESI can be used in information filtering, information retrieval, indexing, and relevancy rankings.

摘要： A system including a storage processing device with an input/output module. The input/output module has port processors to receive and transmit network traffic. The input/output module also has a switch connecting the port processors. Each port processor categorizes the network traffic as fast path network traffic or control path network traffic. The switch routes fast path network traffic from an ingress port processor to a specified egress port processor. The storage processing device also includes a control module to process the control path network traffic received from the ingress port processor. The control module routes processed control path network traffic to the switch for routing to a defined egress port processor. The control module is connected to the input/output module. The input/output module and the control module are configured to interactively support data virtualization, data migration, data journaling, and snapshotting. The distributed control and fast path processors achieve scaling of storage network software. The storage processors provide line-speed processing of storage data using a rich set of storage-optimized hardware acceleration engines. The multi-protocol switching fabric provides a low-latency, protocol-neutral interconnect that integrally links all components with any-to-any non-blocking throughput.

摘要： A system for presenting a virtual advertisement or other virtual content in a sequences of frames of a video presentation utilizes data identifying a candidate region in the sequence of frames, a pixel signature for the region, the signature comprising a range of R, G, B values for pixels based on a standard deviation from an average value, and stored virtual content, such as an advertisement, to be implanted in the candidate region or regions. In operation, as frames having the candidate region are processed by an integration system, the alternative virtual content is substituted by default for the candidate region, except if a pixel value in the region falls outside the pixel signature range. The result is an ad that appears to be on a surface in the video presentation, as images that come between the ad and the viewer occlude the advertisement. Apparatus and methods for providing the video presentation and data sets for regions and advertisements are disclosed as well. Methods are provided for selecting candidate regions and for implanting virtual content in various embodiments.
