Scalable distance-based outlier detection over high-volume data streams
TLDR
We propose the first general framework to handle the three major classes of distance-based outliers in streaming environments, including the traditional distance-threshold based and the nearest-neighbor-based definitions. Expand

Test-pattern-reduced decoding for turbo product codes with multi-error-correcting eBCH codes
TLDR
We present a method to reduce the number of test patterns (TPs) decoded in the Chase-II algorithm for turbo product codes (TPCs) constructed with multi-error correcting extended Bose-Chaudhuri-Hocquengem (eBCH) codes. Expand

  • IEEE Communications Letters
  • 1 March 2018
TLDR
In this letter, we first provide the asymptotic analysis of Raptor codes over binary input additive white Gaussian noise channels using discretized density evolution (DDE) and use it with a DDE-based optimization method to obtain optimized raptor codes with further improvement in decoding thresholds.
