... prediction is resilient to a number of prediction errors by the binary classifiers, provided the codes for the labels are sufficiently diverse. 3.1 Error- correcting CRF training Error- correcting codes can also ... yielding a n-bit vector Γ(x) = {γ 1 (x), γ 2 (x), . . . , γ n (x)}. Now compare this vector to the codes for each label. The vector may not exactly match any of the...

... generalized to codes whose codewords have weights that are divisible by numbers other than four. We say that a code C (over Fundamentals of Error- Correcting Codes Fundamentals of Error- Correcting Codes ... introduced and applied to the determination of bounds on the minimum weight of self-dual codes. Techniques for classifying self-dual codes are presented. Formally self...

... investigate the use of error- correcting output codes (ECOC) for boosting centroid text classifier. The implementation framework is to decompose one multi-class problem into multiple binary problems ... one multi-class problem into multiple binary problems. In order to attack this problem, we use Model- Refinement (Tan et al. 2005) to reduce this so- called bias. The basic id...

... and cylinder skewing and sector-based sparing with one spare sector per track. This needs to be accounted for in mapping logical blocks to the physical sectors. Adding all these factors results in the ... applying logic analyzers to SCSI buses. Bruce Worthington and Greg Ganger at the University of Michigan took this approach and managed to fine-tune the controller-overhead and bus-tra...
