On 21 June at the OpRisk North America 2017 conference in New York, Scott W. Bauguess, Acting Director and Acting Chief Economist of the U.S. Securities and Exchange Commission’s (“SEC”) Division of Economic and Risk Analysis (“DERA”) gave a keynote speech on the use of artificial intelligence by regulators. A transcript of the speech can be found here. Bauguess provided some interesting background on the utility and use of big data and machine learning at the SEC to identify potential misconduct by market participants and investment managers, and the emerging use of artificial intelligence.
Bauguess’ speech discussed the SEC’s use of AI in its regulatory framework, initially discussing machine learning. The SEC currently applies topic modeling methods, such as Latent Dilchlet Allocation (“LDA”). LDA reviews text-based documents (e.g., registration disclosures) and reports on where, and to what extent, particular words appear in each document. This occurs either by: analyzing the probability of words across documents, and within documents, to define the topics they represent (“unsupervised learning”); or incorporating human judgement and direction into the programming of the machine’s algorithms (“supervised learning”).
