Auto-Prompting SAM for Mobile Friendly 3D Medical Image Segmentation

no code implementations28 Aug 2023 Chengyin Li, Prashant Khanduri, Yao Qiang, Rafi Ibn Sultan, Indrin Chetty, Dongxiao Zhu

In addition to the domain gaps between natural and medical images, disparities in the spatial arrangement between 2D and 3D images, the substantial computational burden imposed by powerful GPU servers, and the time-consuming manual prompt generation impede the extension of SAM to a broader spectrum of medical image segmentation applications.

Negative Flux Aggregation to Estimate Feature Attributions

1 code implementation17 Jan 2023 Xin Li, Deng Pan, Chengyin Li, Yao Qiang, Dongxiao Zhu

There are increasing demands for understanding deep neural networks' (DNNs) behavior spurred by growing security and/or transparency concerns.

Learning Compact Features via In-Training Representation Alignment

no code implementations23 Nov 2022 Xin Li, Xiangrui Li, Deng Pan, Yao Qiang, Dongxiao Zhu

Deep neural networks (DNNs) for supervised learning can be viewed as a pipeline of the feature extractor (i. e., last hidden layer) and a linear classifier (i. e., output layer) that are trained jointly with stochastic gradient descent (SGD) on the loss function (e. g., cross-entropy).

FocalUNETR: A Focal Transformer for Boundary-aware Segmentation of CT Images

1 code implementation6 Oct 2022 Chengyin Li, Yao Qiang, Rafi Ibn Sultan, Hassan Bagher-Ebadian, Prashant Khanduri, Indrin J. Chetty, Dongxiao Zhu

Computed Tomography (CT) based precise prostate segmentation for treatment planning is challenging due to (1) the unclear boundary of the prostate derived from CT's poor soft tissue contrast and (2) the limitation of convolutional neural network-based models in capturing long-range global context.

Saliency Guided Adversarial Training for Learning Generalizable Features with Applications to Medical Imaging Classification System

no code implementations9 Sep 2022 Xin Li, Yao Qiang, Chengyin Li, Sijia Liu, Dongxiao Zhu

We hypothesize that adversarial training can eliminate shortcut features whereas saliency guided training can filter out non-relevant features; both are nuisance features accounting for the performance degradation on OOD test sets.
