Abstract

I propose a new characterization of the types of problems for which computational intelligence (CI) tends to be used, namely the identification of approximate abstractions. I then suggest that equity markets provide a challenging example for CI. Because markets are inherently adaptive, they pose a more difficult problem than traditional CI domains. I discuss my experience teaching a CI class that took the development of stock trading systems as a theme. A simple genetic algorithm to generate a trading strategy was developed as a class example. Although the astonishingly good results it achieved were due at least in part to data snooping, a simple unevolved version of the same strategy was almost as profitable. Yet it too had subtle data snooping problems—showing how difficult it is to avoid data snooping entirely, especially in adaptive domains.
股票市场和计算智能
我提出了计算智能(CI)倾向于使用的问题类型的新特征,即近似抽象的识别。然后,我认为股票市场为CI提供了一个具有挑战性的例子。由于市场具有固有的适应性,因此它们比传统的CI领域带来了更困难的问题。我讨论了我教一门以股票交易系统开发为主题的CI课程的经验。开发了一个简单的遗传算法来生成交易策略。尽管它取得的惊人的好结果至少部分归功于数据窥探,但同样策略的一个简单的未进化版本几乎同样有利可图。然而,它也有微妙的数据窥探问题,这表明完全避免数据窥探是多么困难,特别是在自适应领域。
