AI总结:

本文提出函数纠错码以保护消息函数评估免受错误影响,证明其等价于不规则距离码,推导了最优冗余度的通用上下界及简化次优界限,并应用于特定函数与标准纠错码进行比较。

摘要:

在本文中,我们研究函数纠错码,这是一类旨在保护消息的函数评估免受错误影响的新型码。我们证明 FCCs 等价于不规则距离码,即每对码字之间遵循特定给定距离要求的码。利用这些联系,我们研究不规则距离码并推导其最优冗余度的通用上下界。由于这些界限高度依赖于具体函数,我们提供了更易评估的简化次优界限。我们进一步将通用结果应用于感兴趣的特定函数,并将结果与保护整个消息的标准纠错码进行比较。

英文摘要:

In this paper we study function-correcting codes, a new class of codes designed to protect the function evaluation of a message against errors. We show that FCCs are equivalent to irregular-distance codes, i.e., codes that obey some given distance requirement between each pair of codewords. Using these connections, we study irregular-distance codes and derive general upper and lower bounds on their optimal redundancy. Since these bounds heavily depend on the specific function, we provide simplified, suboptimal bounds that are easier to evaluate. We further employ our general results to specific functions of interest and compare our results to standard error-correcting codes, which protect the whole message.
