  • Publication number: 20150188580
    Abstract: A universal error-correction circuit with fault-tolerant nature includes an error-correction unit with fault-tolerant nature implemented by a logic gate, where digital input signals of the error-correction unit with fault-tolerant nature are separately I0, I1 . . . , I2k?1, and I2k, digital output signals of the error-correction unit with fault-tolerant nature are separately O0, O1, . . . , Ok?2, and Ok?1, and the digital input signals and the digital output signals belong to a set {0,1}, where k is a positive integer. The error-correction unit with fault-tolerant nature is configured to, when k=1, set O0=I0 if I0=I1, and O0=I2 otherwise; and when k>1, set Ok?1=I2k?1 if Ok?2=I2k?1, and Ok?1=I2k otherwise. Because a logical relationship between input and output is uniquely certain, the error-correction circuit with fault-tolerant nature may be implemented only by a logic gate.

  • Publication number: 20150039619
    Abstract: A canopy clustering process merges at least one set of multiple single-center canopies together into a merged multi-center canopy. Multi-center canopies, as well as the single-center canopies, can then be used to partition data objects in a dataset. The multi-center canopies allow a canopy assignment condition constraint to be relaxed without risk of leaving any data objects in a dataset outside of all canopies. Approximate distance calculations can be used as similarity metrics to define and merge canopies and to assign data objects to canopies. In one implementation, a distance between a data object and a canopy is represented as the minimum of the distances between the data object and each center of a canopy (whether merged or unmerged), and the distance between two canopies is represented as the minimum of the distances for each pairing of the center(s) in one canopy and the center(s) in the other canopy.
