A system and method for determining the significance of association rules which are mined from a dataset is provided. Predictive association rules may also be generated based on the significance of an association rule. The statistical significance of an association rule may be used to estimate the n ...
A method and system for performing spatial proximity joins on high-dimensional points representing data objects of a database in parallel in a multiprocessor system. The method comprises the steps of: partitioning the data points among the processors; creating index structures for the data points of ...
A method and system for identifying groups of pages of common interest from a collection of hyper-linked pages are disclosed. A plurality of community cores are identified from the collection where each core includes first and second sets of pages, and each page in the first set points to every page ...
A system and method for automatic generation of a comparison list given two different classifications, and automatic sorting of the list in order of similarity. A first dictionary is generated including a subset of words contained in a first document set, the first document set including at least on ...
A wafer-disposition method and apparatus are disclosed where the disposition is based on a model of systematic misalignment errors. The method comprises the steps of: modeling the misalignment errors between the mask and wafer as a mathematical model using measured misalignment data, generating a co ...
A portable computer includes a battery and a connection to an external power source, a two-speed data storage device being supplied power from one or more of the battery and the external power source, and a controller attached to the storage device. With the invention, when the storage device is pow ...
A method and system for generating a decision-tree classifier in parallel in a shared-memory multiprocessor system is disclosed. The processors first generate in the shared memory an attribute list for each record attribute. Each attribute list is assigned to a processor. The processors independentl ...
A low-power dual-g.sub.m differential operational transconductance amplifier (OTA) having a differential input for improved common-mode noise rejection, a high transconductance for power savings, and circuitry for controlling its output conductance. The OTA includes a pair of input inverters for rec ...
A method and apparatus for efficiently matching a large collection of user profiles against a large volume of data in a webcasting system. The invention generally includes in one embodiment four steps to parallelize the profiles. First, an initial profile set is partitioned into several subsets also ...
A method and disk controller for handling missed revolutions in a disk drive having a rotating data media are disclosed. The method is based on a Rotational Positioning Optimization (RPO) algorithm and comprises the steps of: selecting a primary and a secondary command from the queue using the RPO w ...
