Financial firms are putting more resources towards using complex forms of machine learning. And that means they'll also need to develop ways to better understand the tech and explain it both internally and to regulators. A recent survey by data giant Refinitiv on the use of artificial intelligence and machine learning in financial services found that 75% of respondents were using some form of deep learning, a type of ML that includes a series of complex, ever-evolving calculations. Those surveyed included data scientists, quants, and executives at a variety of financial firms. Geoffrey Horrell, head of Refinitiv Labs in London, told Business Insider that the surge of interest in deep learning means firms will need to invest resources in understanding these complex algorithms.

Financial news giant Thomson Reuters has released its Knowledge Graph Feed, a way of instantly visualising the connections between lots of data sources, which it describes as "the first financial social network". The Knowledge Graph system is an open source, standardised data modelling system composed of Permanent Identifiers (PermID) which connect some two billion relationships. Newsweek is hosting an AI and Data Science in Capital Markets conference in NYC, Dec. 6-7. Geoffrey Horrell, director, Product Incubation Financial and Risk, Thomson Reuters, explained: "What we are delivering is like a social network but it's the first financial social network.
