Inria and Nokia Bell Labs
offer a POstDoc position on causal discovery of extended summary causal graphs for noisy-OR
models of event sequences starting as soon as possible and no later than October or November 2023.
Goals
The objective of this project is to develop methods to infer causal graphs from observational time
series/event-type data generated according to generic noisy-OR models [1]. The causal graphs
considered can either be full window causal graphs or a summarized version as extended summary
causal graphs [2] and may contain or not hidden common causes. Generic noisy-OR models are structural
causal models (SCM) with noisy-OR gates which allow to estimate the effect of multiple causes even if
they have never been observed together. We will consider here both simple noisy-OR models in which
the noisy-OR gates directly define the SCM, and complex ones in which the noisy-OR gates are sub-parts
of an underlying SCM.
