Identifiability of deep generative models without auxiliary information
…, P Ravikumar, B Aragam - Advances in Neural …, 2022 - proceedings.neurips.cc
We prove identifiability of a broad class of deep latent variable models that (a) have universal
approximation capabilities and (b) are the decoders of variational autoencoders that are …

[PDF][PDF] Concave penalized estimation of sparse Gaussian Bayesian networks
We develop a penalized likelihood estimation framework to learn the structure of Gaussian
Bayesian networks from observational data. In contrast to recent methods which accelerate …

Dags with no tears: Continuous optimization for structure learning
Estimating the structure of directed acyclic graphs (DAGs, also known as Bayesian networks)
is a challenging problem since the search space of DAGs is combinatorial and scales …

Learning sparse nonparametric dags
We develop a framework for learning sparse nonparametric directed acyclic graphs (DAGs)
from data. Our approach is based on a recent algebraic characterization of DAGs that led to …

Learning linear causal representations from interventions under general nonlinear mixing
…, E Rosenfeld, B Aragam… - Advances in …, 2024 - proceedings.neurips.cc
We study the problem of learning causal representations from unknown, latent interventions
in a general setting, where the latent distribution is Gaussian but the mixing function is …

Dagma: Learning dags via m-matrices and a log-determinant acyclicity characterization
The combinatorial problem of learning directed acyclic graphs (DAGs) from data was
recently framed as a purely continuous optimization problem by leveraging a differentiable …

Learning nonparametric latent causal graphs with unknown interventions
We establish conditions under which latent causal graphs are nonparametrically identifiable
and can be reconstructed from unknown interventions in the latent space. Our primary focus …

Dynotears: Structure learning from time-series data
…, K Georgatzis, P Beaumont, B Aragam - International …, 2020 - proceedings.mlr.press
We revisit the structure learning problem for dynamic Bayesian networks and propose a
method that simultaneously estimates contemporaneous (intra-slice) and time-lagged (inter-slice…

Precision Lasso: accounting for correlations and linear dependencies in high-dimensional genomic data
Motivation Association studies to discover links between genetic markers and phenotypes are
central to bioinformatics. Methods of regularized regression, such as variants of the Lasso, …

Learning latent causal graphs via mixture oracles
…, P Ravikumar, B Aragam - Advances in Neural …, 2021 - proceedings.neurips.cc
We study the problem of reconstructing a causal graphical model from data in the presence
of latent variables. The main problem of interest is recovering the causal structure over the …
