Uncovering the effects of model initialization on deep model generalization: A study with adult and pediatric Chest X-ray images

no code implementations20 Sep 2023 Sivaramakrishnan Rajaraman, Ghada Zamzmi, Feng Yang, Zhaohui Liang, Zhiyun Xue, Sameer Antani

Model initialization techniques are vital for improving the performance and reliability of deep learning models in medical computer vision applications.

Semantically Redundant Training Data Removal and Deep Model Classification Performance: A Study with Chest X-rays

no code implementations18 Sep 2023 Sivaramakrishnan Rajaraman, Ghada Zamzmi, Feng Yang, Zhaohui Liang, Zhiyun Xue, Sameer Antani

Deep learning (DL) has demonstrated its innate capacity to independently learn hierarchical features from complex and multi-dimensional data.

Does image resolution impact chest X-ray based fine-grained Tuberculosis-consistent lesion segmentation?

no code implementations10 Jan 2023 Sivaramakrishnan Rajaraman, Feng Yang, Ghada Zamzmi, Zhiyun Xue, Sameer Antani

Literature is sparse in discussing the optimal image resolution to train these models for segmenting the Tuberculosis (TB)-consistent lesions in CXRs.

Generalizability of Deep Adult Lung Segmentation Models to the Pediatric Population: A Retrospective Study

no code implementations4 Nov 2022 Sivaramakrishnan Rajaraman, Feng Yang, Ghada Zamzmi, Zhiyun Xue, Sameer Antani

In this work, our goal is to (i) analyze the generalizability of deep adult lung segmentation models to the pediatric population and (ii) improve performance through a stage-wise, systematic approach consisting of CXR modality-specific weight initializations, stacked ensembles, and an ensemble of stacked ensembles.

Deep ensemble learning for segmenting tuberculosis-consistent manifestations in chest radiographs

no code implementations13 Jun 2022 Sivaramakrishnan Rajaraman, Feng Yang, Ghada Zamzmi, Peng Guo, Zhiyun Xue, Sameer K Antani

We observed that the stacking ensemble demonstrated superior segmentation performance (Dice score: 0. 5743, 95% confidence interval: (0. 4055, 0. 7431)) compared to the individual constituent models and other ensemble methods.

Deep Cervix Model Development from Heterogeneous and Partially Labeled Image Datasets

no code implementations18 Jan 2022 Anabik Pal, Zhiyun Xue, Sameer Antani

We believe that the present research shows a novel direction in developing criteria-specific custom deep models for cervical image classification by combining images from different sources unlabeled and/or labeled with varying criteria, and addressing image access restrictions.

Synthetic Sample Selection via Reinforcement Learning

no code implementations26 Aug 2020 Jiarong Ye, Yuan Xue, L. Rodney Long, Sameer Antani, Zhiyun Xue, Keith Cheng, Xiaolei Huang

However, the quality control of synthetic images for data augmentation purposes is under-investigated, and some of the generated images are not realistic and may contain misleading features that distort data distribution when mixed with real images.

Selective Synthetic Augmentation with Quality Assurance

no code implementations9 Dec 2019 Yuan Xue, Jiarong Ye, Rodney Long, Sameer Antani, Zhiyun Xue, Xiaolei Huang

To mitigate these issues, we investigate a novel data augmentation pipeline that selectively adds new synthetic images generated by conditional Adversarial Networks (cGANs), rather than extending directly the training set with synthetic images.
