Fig. 4: Detecting causal networks in real biological systems.
From: Causal network inference based on cross-validation predictability
a A food chain network of plankton. b Causality of plankton detected by the CVP algorithm. c The detected the causal network for respiratory diseases by the CVP algorithm. The arrows represent the direction of causation, and the same colors represent the same dependent variables. d The inferred impact of environmental interactions on respiratory diseases by the CVP algorithm with darker heat map colors indicating stronger causal relationships. e and f show the reconstructed the network of the number of people spreading New Coronavirus by the CVP algorithm in Kanto and Tohoku of Japan, respectively.
