用混沌映射压缩数据,实现简单可解释的分类

Chaotic Map based Compression Approach to Classification

  • 将数据映射到混沌系统的初值区间,通过斜帐篷映射编码与恢复
  • 乳腺癌数据集达92.98%准确率,接近朴素贝叶斯的94.74%
  • 适合追求可解释性、轻量级模型的研究者

现代机器学习方法常以性能为优先,导致复杂度高、计算需求大且可解释性差。本文提出一种新框架,从信息论视角重新理解学习,将其视为寻找能捕捉数据内在结构的紧凑表示的编码方案。不同于传统拟合复杂模型的方法,我们提出一种根本性差异的策略:将数据映射到动力系统初值区间。所提出的GLS(广义吕罗思级数)编码压缩分类器使用斜帐篷映射,既用于数据编码,也用于后续恢复。该简单框架效果显著,在乳腺癌数据集上达到92.98%准确率,接近朴素贝叶斯的94.74%。尽管未超越现有先进方法,但其意义在于证明:更简单、更具可解释性的方法也能实现竞争力表现。

原文摘要 · Abstract (English)

Modern machine learning approaches often prioritize performance at the cost of increased complexity, computational demands, and reduced interpretability. This paper introduces a novel framework that challenges this trend by reinterpreting learning from an information-theoretic perspective, viewing it as a search for encoding schemes that capture intrinsic data structures through compact representations. Rather than following the conventional approach of fitting data to complex models, we propose a fundamentally different method that maps data to intervals of initial conditions in a dynamical system. Our GLS (Generalized Lüroth Series) coding compression classifier employs skew tent maps - a class of chaotic maps - both for encoding data into initial conditions and for subsequent recovery. The effectiveness of this simple framework is noteworthy, with performance closely approaching that of well-established machine learning methods. On the breast cancer dataset, our approach achieves 92.98\% accuracy, comparable to Naive Bayes at 94.74\%. While these results do not exceed state-of-the-art performance, the significance of our contribution lies not in outperforming existing methods but in demonstrating that a fundamentally simpler, more interpretable approach can achieve competitive results.
