我们提出了一个随机编码模型,该模型可深入了解有损弦匹配算法的潜在机制。这种理想化的模型基于操纵类型而不是代码字。我们将自适应代码簿建模为混合类型的随机代码,其类型分布随时间而随着其尺寸的增加而演变。模型行为表现出一种自然类型选择的机制,该机制加强了“良好类型”。
We propose a random coding model which gives insight into the underlying mechanism of lossy string-matching algorithms. This idealised model is based on manipulating types rather than codewords. We model the adaptive codebook as a mixed type random code, whose type distribution evolves with time as its dimension increases. The model behavior exhibits a mechanism of natural type selection which reinforces "good types".
