Join us to explore causality in data science with speakers Jed Dougherty of Dataiku and renowned NYU Professor Bud Mishra!
Many thanks to NYC Data Science Academy (www.nycdatascience.com) for hosting us.
A recent analysis, conducted by the Federal Reserve Board, showed that before and during the financial crisis of 2008 the average bank profit-and-loss (PnL) did not exceed the bank VaR from December 2003 to April 2007, while the bank average PnL exceeded VaR six times from June 2007 to March 2008. In other words, banks which maintained capital reserves equal to their Value-at-Risk faced on average six near bankruptcies during the crisis. What most intrigued the economists and political and social scientists, was the sheer lack of a single plausible causal explanation of these events – which is thought to have ranged from (i) “One eyed Scottish idiot!” (Jeremy Clarkson); (ii) “Complex financial products; undisclosed conflicts of interest; the failure of regulators, the credit rating agencies, and the market itself,” Interest Rate Spreads, Emerging Markets: e.g., BRICS – and so on. Both the unusual abruptness and intuitive implausibility earned such scenarios the name, “Black Swan Events” – and many more. It also raised the question whether there is a theory of “causality” that could have rigorously explained such events empirically from data – we suggest that the machinery of model checking for a suitably expressive logic (e.g., PCTL Probabilistic Computational Tree Logic, a branching time propositional modal logic) provides just the right capabilities to succinctly specify and efficiently verify statements about such scenario. It derives its power from the way it combines logic, probability and reasoning about time, which are lacked in the currently popular black-box AI systems.
