Marcos Lopez de Prado，想必国内的读者这几年应该熟悉一些了吧！, 公众号第一次介绍Marcos Lopez de Prado，则是来自他一篇论文：《The 7 Reasons Most Machine Learning Funds Fail》，公众号进行了解读，详见：, 此后我们还对他的另一篇论文进行了解读：《The 7 Reasons Most Econometric Investments Fail》，详见：, 在国内大多数人眼中，最为出名的是他那本《Advances in Financial Machine Learning》：, 今年又出了一本：《Machine Learning for Asset Managers》, 最新，Marcos Lopez de Prado应邀在美国计算机学会关于金融领域的人工智能会议上发表主旨演讲，会议将于2020年10月14日至16日举行：, https://ai-finance.org/conference-program/, 不过Marcos Lopez de Prado已经把这次会议的内容作了预告分享，让我们来看看有什么精彩的内容吧！, 黑天鹅是一种前所未有的极端事件。例如，2010年5月6日的闪电崩盘（flash crash）。, 官方的调查是：可能是因为市场下达了卖出7.5万份E-miniS&P500期货的指令。, 这一大笔订单导致了订单流量的持续失衡，从而引发了做市商之间的一连串停止交易，直到没有人支持竞购。不平衡的订单流是常态，具有不同程度的持续性。10%的价格突然下跌属于黑天鹅事件。但原因我们可以从微观结构理论搞清楚：, https://jpm.pm-research.com/content/37/2/118, 强化学习方法无希腊语和模型的，它们纯粹是经验性的，几乎没有理论假设。这些模型在做套期保值时考虑了更多的变量和数据点，并能以更快的速度生成更精确的套期保值。, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2708678, http://faculty.london.edu/avmiguel/DeMiguel-Garlappi-Uppal-RFS.pdf, 横断面研究对异常值的存在特别敏感。即使是很小比例的异常值也会造成很大比例的错误信号：买入应该卖出（假阳性），卖出应该买入（假阴性）。, 只有5%的异常值，横截面回归产生了34%的分类误差。相比之下，RANSAC的分类错误为1%。, 2、这是从业者经常面临的情况。我们常常知道自己是想买还是想卖一种产品，而剩下的唯一问题是，在这种赌注中我们应该承担多少风险。, 合约的方向（Long | Short）和合约的大小（size）无法在三隔栏方法中体现，也就导致无法止盈和止损，所以Marcos Lopez de Prado引出了Meta-Labeling作为数据的进一步处理方法。, 金融中用机器学习的一个常见错误时同时学习仓位的方向和规模。具体而言，方向决策（买/卖）是最基本的决策，规模决策（size decision）是风险管理决策，即我们的风险承受能力有多大，以及对于方向决策有多大信心。我们没必要用一个模型处理两种决策，更好的做法是分别构建两个模型：第一个模型来做方向决策，第二个模型来预测第一个模型预测的准确度。很多ML模型表现出高精确度（precision）和低召回率（recall），即（正确预测为交易机会的次数/预测为交易机会的次数）很高，（正确预测为交易机会的次数/交易机会的次数）而 很低。这意味着这些模型过于保守，大量交易机会被错过。F1-score 综合考虑了精确度和召回率，是更好的衡量指标，元标签（Meta-Labeling）有助于构建高 F1-score 模型。首先（用专家知识）构建一个高召回率的基础模型，即对交易机会宁可错杀一千，不可放过一个。随后构建一个ML模型，用于决定我们是否应该执行基础模型给出的决策。, Meta-Labeling的核心优势在于将确定头寸的任务分解为了两个部分：头寸方向，头寸大小, 对于二元分类，meta-labeling可以有效帮助我们提升F1-score。在确定头寸方向的过程中，我们首先建立一个ML模型 (primary model) ，尽力提高查全率 (recall)。随后我们对该ML预测的正例使用meta-labeling，并建立第二个ML模型 (secondary model) 来提高查准率 (precision)。第二个ML模型的主要目的是从已经挑选出的机会中再一次筛选投资标的。, 2、元标签+ML减少了过拟合的可能性，即ML模型仅对交易规模决策不对交易方向决策，避免一个ML模型对全部决策进行控制。, 3、元标签+ML的处理方式允许更复杂的策略架构，例如：当基础模型判断应该多头，用ML模型来决定多头规模；当基础模型判断应该空头，用另一个ML模型来决定空头规模。, 5、头寸方向和头寸大小的分解允许我们先简后繁。例如我们可以使用复杂模型分别对多头和空头进行专门训练确定头寸大小。, 3、这种关系的性质可能极其复杂，但我们总是可以研究哪些特征更重要。例如，即使机器学习算法不能推导出牛顿引力定律的解析公式，它也会告诉我们质量和距离是关键的特征。, 2、这些决定并不是完全随意的，它们对应于一个复杂的逻辑，而这个逻辑不能用一组简单的公式或一个定义良好的过程来表示。, 下图显示了债券的散点图，作为两个特征(x,y)的函数，其中默认值被涂成红色。中间的图表显示，传统的计量经济学方法无法建立这种复杂的非线性关系的模型。右图显示一个非常简单的机器学习算法，其表现良好。, 再如国内的上市公司，ChinaScope数库对每篇文章的实体进行了情绪识别给出了正负面情绪，同时也对相关实体和整篇文章给出情绪值。这个值就可以应用在量化策略中去：, 在这个例子中，投资组合的再平衡是有利可图的，因为它占据了买卖价差的约三分之一（约50个基点的价格）。, Y 轴显示给定数量的试验（x轴）的最大夏普比率(max {SR})的分布。较浅的颜色表示获得该结果的可能性较高，虚线表示预期值。, 例如，在仅进行1000次独立的回测之后，即使策略的真实夏普比率为零，预期的最大夏普比率 (E[max{SR}]) 也是 3.26！, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3177057.
