上财团队 投稿 量子位 | 公众号 QbitAI 在量化金融的底层,Alpha因子本质上是一段可执行的代码逻辑,它们试图将嘈杂的市场数据映射为精准的交易信号。然而,长期以来,自 动化因子挖掘始终被困在"两难"的夹缝中:传统的遗传规划 (Genetic Programming,GP) 虽然擅长在海量空间中进行进化搜索,但其 本质是"盲目的随机变异"。 它们在回测中过度拟合了历史噪声,却在逻辑上极难解释,如同一个充满巧合的黑盒。而新兴的大语言模型 (LLM) 虽然具备强大的语义 理解能力,能像人类一样读懂金融理论,但在处理高精度的量化逻辑时,却容易陷入"语义漂移"与"幻觉"。生成的代码往往语法完美,但在 经济学逻辑上支离破碎,甚至不仅无法复现,更难以在实盘中生存。 这引发了一个根本性的思考: 我们能否构建一个智能体,既拥有机器般不知疲倦的进化探索能力,又具备人类程序员般严谨的逻辑控制 力? 正是在这一背景下,QuantaAlpha团队联合上海财经大学AIFin Lab等机构,提出了 QuantaAlpha 框架:一种全新的自进化Agent Alpha 因子挖掘框架。 核心框架解析:基于轨迹的自进化范式 Quant ...
