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

B Aragam, Q Zhou - The Journal of Machine Learning Research, 2015 - jmlr.org
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

X Zheng, B Aragam, PK Ravikumar… - Advances in neural …, 2018 - proceedings.neurips.cc
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

X Zheng, C Dan, B Aragam… - International …, 2020 - proceedings.mlr.press
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

K Bello, B Aragam, P Ravikumar - Advances in Neural …, 2022 - proceedings.neurips.cc
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

Y Jiang, B Aragam - Advances in Neural Information …, 2024 - proceedings.neurips.cc
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

H Wang, BJ Lengerich, B Aragam, EP Xing - Bioinformatics, 2019 - academic.oup.com
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 …
