KGS: Causal Discovery Using Knowledge-guided Greedy Equivalence Search

no code implementations11 Apr 2023 Uzma Hasan, Md Osman Gani

Prior causal information such as the presence or absence of a causal edge can be leveraged to guide the discovery process towards a more restricted and accurate search space.

A Survey on Causal Discovery Methods for I.I.D. and Time Series Data

3 code implementations27 Mar 2023 Uzma Hasan, Emam Hossain, Md Osman Gani

The ability to understand causality from data is one of the major milestones of human-level intelligence.

eCDANs: Efficient Temporal Causal Discovery from Autocorrelated and Non-stationary Data (Student Abstract)

no code implementations6 Mar 2023 Muhammad Hasan Ferdous, Uzma Hasan, Md Osman Gani

Conventional temporal causal discovery (CD) methods suffer from high dimensionality, fail to identify lagged causal relationships, and often ignore dynamics in relations.

CDANs: Temporal Causal Discovery from Autocorrelated and Non-Stationary Time Series Data

1 code implementation7 Feb 2023 Muhammad Hasan Ferdous, Uzma Hasan, Md Osman Gani

Our proposed method addresses several limitations of existing causal discovery methods for autocorrelated and non-stationary time series data, such as high dimensionality, the inability to identify lagged causal relationships, and overlooking changing modules.

CKH: Causal Knowledge Hierarchy for Estimating Structural Causal Models from Data and Priors

no code implementations28 Apr 2022 Riddhiman Adib, Md Mobasshir Arshed Naved, Chih-Hao Fang, Md Osman Gani, Ananth Grama, Paul Griffin, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

Using CKH, we present a methodological framework for encoding causal priors from various information sources and combining them to derive an SCM.

Causal Discovery on the Effect of Antipsychotic Drugs on Delirium Patients in the ICU using Large EHR Dataset

no code implementations28 Apr 2022 Riddhiman Adib, Md Osman Gani, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

To explore safety outcomes associated with APD, we aim to build a causal model for delirium in the ICU using large observational data sets connecting various covariates correlated with delirium.

Multispectral Object Detection with Deep Learning

no code implementations5 Feb 2021 Md Osman Gani, Somenath Kuiry, Alaka Das, Mita Nasipuri, Nibaran Das

Moving outside the visible spectrum range, such as the thermal spectrum or the near-infrared (NIR) images, is much more beneficial in low visibility conditions, NIR images are very helpful for understanding the object's material quality.

Structural Causal Model with Expert Augmented Knowledge to Estimate the Effect of Oxygen Therapy on Mortality in the ICU

no code implementations28 Oct 2020 Md Osman Gani, Shravan Kethireddy, Marvi Bikak, Paul Griffin, Mohammad Adibuzzaman

Recent advances in causal inference techniques, more specifically, in the theory of structural causal models, provide the framework for identification of causal effects from observational data in the cases where the causal graph is identifiable, i. e., the data generating mechanism can be recovered from the joint distribution.
