On the Locality of Codeword Symbols in Non-Linear Codes

WebConsider a linear [n,k,d]_q code C. We say that that i-th coordinate of C has locality r, if the value at this coordinate can be recovered from accessing some other r coordinates of C. Data storage applications require codes with small redundancy, low locality for information coordinates, large distance, and low locality for parity coordinates. In this paper we carry … Web1 de mar. de 2024 · The i-th code symbol of a linear code C is said to have locality r, if x i in each codeword x ∈ C can be recovered by r other coded symbols (i.e., x i is a function of some other r symbols x i 1, x i 2, …, x i r). A linear code is said to have locality r if every code symbol has locality at most r. data analysis software list

Web5 de dez. de 2024 · Locally recoverable codes are widely used in distributed and cloud storage systems. In this paper, we first present a construction of near MDS codes with oval polynomials and then determine the locality of the codes. It turns out that the near MDS codes and their duals are both distance-optimal and dimension-optimal locally … bitgo ofacWebConsider a possibly non-linear (n,K,d)q code. Coordinate i has locality r if its value is determined by some r other coordinates. A recent line of work obtained an optimal trade-off between information locality of codes and their redundancy. Further, for linear codes meeting this trade-off, structure theorems were derived. In this work we give a new proof … data analysis stock image
