Counterfactual Generation Under Confounding

no code implementations22 Oct 2022 Abbavaram Gowtham Reddy, Saloni Dash, Amit Sharma, Vineeth N Balasubramanian

Given a causal generative process, we formally characterize the adverse effects of confounding on any downstream tasks and show that the correlation between generative factors (attributes) can be used to quantitatively measure confounding between generative factors.

Evaluating and Mitigating Bias in Image Classifiers: A Causal Perspective Using Counterfactuals

no code implementations17 Sep 2020 Saloni Dash, Vineeth N Balasubramanian, Amit Sharma

We present a method for generating counterfactuals by incorporating a structural causal model (SCM) in an improved variant of Adversarially Learned Inference (ALI), that generates counterfactuals in accordance with the causal relationships between attributes of an image.

Synthetic Event Time Series Health Data Generation

no code implementations14 Nov 2019 Saloni Dash, Ritik Dutta, Isabelle Guyon, Adrien Pavao, Andrew Yale, Kristin P. Bennett

Due to the complexity of the real data, in which each patient visit is an event, we transform the data by using summary statistics to characterize the events for a fixed set of time intervals, to facilitate analysis and interpretability.
