    1. Building probabilistic causal models has always been a challenge. The direction of causality is often difficult to establish and the process of constructing the causal graph with the probabilities behind requires the input of a variety of domain knowledge experts. Moreover, collecting inputs from experts can be costly and inefficient. But what if expert knowledge can be mined directly from the web from thousands of daily published news articles (wisdom-of-the-crowds) through NLP techniques and streamlined through a fast and automated process that can produce a causal model in a matter of seconds? We discuss an approach in our latest paper:https://lnkd.in/eSDYJ7D#pgm #datascience #bayesiannetworks #causalmodels #artificialintelligence #machinelearning #nlp #finance Pierre Haren Dr. Olav Laudy Allen Ginsberg Marcos Lopez de Prado Gautier Marti Charles-Albert Lehalle Paul Bilokon, PhD Saeed Amen Matthew Dixon Igor Halperin N Joshua Madan Daphne Koller Kevin Murphy Joseph Simonian, Ph.D. Dr. Ron Dembo Alexander Fleiss
