Belief propagation (BP) decoding algorithm is a well-known decoding algorithm for LDPC codes. Most LDPC codes with long lengths have short cycles in their Tanner graphs, which reduce the performance of the BP algorithm. In this paper, we present 2 methods to improve the BP decoding algorithm ...
shortened RS code截短RS码 3)shortened code缩短码 1.Furthermore,according to the basic algorithm steps of BM,the practical shortened code(50,32)is analyzed through the three-stage pipeline algorithm architecture.根据BM迭代译码算法的基本步骤,采用三级流水算法结构并对实际应用的缩短码(50,32)(纠二检四...

The approach consists of two components, 1) a mining algorithm to discover patterns for matching two short-texts, defined in the product space of dependency trees, and 2) a deep neural network for matching short texts using the mined patterns, as well as a learning algorithm to build the ...
For example: Normally a fibonacci algorithm implemented recursive is shorter (and more readeble) than Iterative fibonacci, But Iterative Fibonacci is more memory efficienty than recursive version. Another example: A lot of code's have thousands lines and thousands of lines. But what counts in the...
Inspired by a control perspective, we propose a new algorithm SFT-PG: Shortcut Fine-Tuning with Policy Gradient, and prove that under certain assumptions, gradient descent of diffusion models with respect to IPM is equivalent to performing policy gradient. To our best knowledge, this is the ...
Codes can be shortened for easier communication, in which case they can be used regionally or in combination with a reference location that all users of this short code need to be aware of. If the reference location is given in form of a location name, use of a geocoding service might be...
Formula like |neig(b)| = |b| give us a hint for Hall's marriage theorem: Suppose the maximal matching of this bipartite graph is n — d, then we can find b, a subset of boys, such that |b| — |neig(b)| = d. (We can use maxflow algorithm to find such set, by getting ...
