Principles for causal discovery: independent noise in (post-)nonlinear causal model (Zhang and Hyvärinan, UAI’09 & ECML’09; Zhang and Chan, ICONIP’06); independent transformation in deterministic systems (Janzing et al., AI12 & Daniusis et al., UAI’10); exogeneity (Zhang et al., TARK’15); independent changes (generalized notation of invariance) in nonstationary/heterogeneous data (Zhang et al., IJCAI’17; Huang et al., ICDM’17; Zhang et al., arxiv’15...); constraints on and estimation of functional causal models (Zhang et al., TIST'16); Triad conditions for estimating linear, non-Gaussian hidden causal representations (Cai et al., NeurIPS'19).
Causal discovery from various types of nonstationary and heterogeneous data: general framework for causal discovery from independent but non-identically distributed time series or multiple-domain data and beyond (Zhang et al., IJCAI’17; Huang et al., ICDM’17; Zhang et al., arxiv’15); causal discovery and forecasting in nonstationary environments with state-space modeling (Huang et al., ICML’19); causal discovery with fixed general nonlinear causal mechanisms and nonstationary noise (Monti et al., UAI’19); modeling and estimation of time-varying causal relations with Gaussian processes (Huang et al., IJCAI’15); multi-domain causal structure learning in linear systems with regression invariance (Ghassami et al., NIPS'17) or with independent changes (Ghassami et al., NeurIPS’18).
