Using Machine Learning to Predict the Diagnosis, Management and Severity of Pediatric Appendicitis
Published in Frontiers in Pediatrics, 2021
This pilot study is the first to simultaneously predict the diagnosis, management, and severity of the disease in children with suspected appendicitis. We present the first ML model for appendicitis that was deployed as an open access easy-to-use online tool.

A Deep Variational Approach to Clustering Survival Data
Published in 10th International Conference on Learning Representations, ICLR 2022, 2022
We introduce a novel semi-supervised probabilistic approach to cluster survival data by leveraging recent advances in stochastic gradient variational inference. Our method employs a deep generative model to uncover the underlying distribution of both the explanatory variables and censored survival times.

Debiasing Deep Chest X-Ray Classifiers using Intra- and Post-processing Methods
Published in 7th Machine Learning for Healthcare Conference, MLHC 2022, 2022
This work presents two intra-processing techniques based on fine-tuning and pruning an already-trained neural network that can help achieve group fairness of deep medical image classifiers when deploying them in domains with different fairness considerations and constraints.

Interpretable and Explainable Machine Learning: A Methods-centric Overview with Concrete Examples
Published in Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery, 2023
This review is intended for a general machine learning audience interested in exploring the challenges of interpretation and explanation beyond the logistic regression or random forest variable importance. We examine inductive biases behind interpretable and explainable machine learning and illustrate them with concrete examples from the literature.

Interpretable and intervenable ultrasonography-based machine learning models for pediatric appendicitis
Published in Medical Image Analysis, 2024
This work presents interpretable machine learning models for predicting the diagnosis, management and severity of suspected appendicitis using ultrasound images. Our approach utilizes concept bottleneck models that facilitate interpretation and interaction with high-level concepts understandable to clinicians.
