    摘要： An adaptive search method in feature vector space which can quickly search the feature vector space indexed based on approximation for a feature vector having features similar to a query vector according to a varying distance measurement is provided. The adaptive search method includes the steps of (a) performing a similarity measurement on a given query vector within the feature vector space, and (b) applying search conditions limited by the result of the similar measurement obtained in the step (a) and performing a changed similarity measurement on the given query vector. According to the adaptive search method, the number of candidate approximation regions is reduced during a varying distance measurement such as an on-line retrieval, which improves the search speed.

    摘要： A method is provided for indexing feature vectors within feature vector data space which includes adaptively forming approximation of the feature vectors on the basis of statistical distribution of feature vector data within the feature vector data space. The method for indexing feature vector data space of the present invention efficiently indexes vector space having high-dimensionality in which generally feature vectors are not uniformly distributed. Also, the method for indexing feature vector data space has an advantage that indexing can be easily upgraded when new feature vector data is added.

    摘要： Integrated trace selection and profiling in dynamic optimizers may include selecting a trace head based on profile of basic blocks that are executed. The basic blocks executed from the trace head may be recorded as a trace. The trace may be added to a trace nursery in non-compiled state. The trace may be interpreted and profiled until the trace matures. Under a profiling mode, path sensitive runtime information such as values, types, targets of call-sites, and exit frequencies can be collected. The trace may be moved out of the nursery to a compilation queue in response to determining that the trace has matured based on an execution count of the profiled trace.

    摘要： A computer implemented method, apparatus, and computer usable program code for compiling source code for performing a complex operation followed by a complex reduction operation. A method is determined for generating executable code for performing the complex operation and the complex reduction operation. Executable code is generated for computing sub-products, reducing the sub-products to intermediate results, and summing the intermediate results to generate a final result in response to a determination that a reduced single instruction multiple data method is appropriate.

    摘要： An execution trace of building blocks of computer code includes a head building block at which the execution trace starts, and a tail building block at which the execution trace ends. The building blocks are executable in a sequence from the head building block to the tail building block. The execution trace is truncated at a particular building block of the execution trace, which becomes the tail building block. The particular building block can correspond to a head building block of an additional execution trace, and/or to a loop header building block of a loop within the execution trace and at which the loop is entered. The execution trace is a compilation unit on which basis a trace-based compiler computer program generates an executable version of the code at least by compiling these units.
