Emergent Language Symbolic Autoencoder (ELSA) with Weak Supervision to Model Hierarchical Brain Networks

no code implementations15 Apr 2024 Ammar Ahmed Pallikonda Latheef, Alberto Santamaria-Pang, Craig K Jones, Haris I Sair

Brain networks display a hierarchical organization, a complexity that poses a challenge for existing deep learning models, often structured as flat classifiers, leading to difficulties in interpretability and the 'black box' issue.

3D-MIR: A Benchmark and Empirical Study on 3D Medical Image Retrieval in Radiology

1 code implementation23 Nov 2023 Asma Ben Abacha, Alberto Santamaria-Pang, Ho Hin Lee, Jameson Merkow, Qin Cai, Surya Teja Devarakonda, Abdullah Islam, Julia Gong, Matthew P. Lungren, Thomas Lin, Noel C Codella, Ivan Tarapov

The increasing use of medical imaging in healthcare settings presents a significant challenge due to the increasing workload for radiologists, yet it also offers opportunity for enhancing healthcare outcomes if effectively leveraged.

Region-based Contrastive Pretraining for Medical Image Retrieval with Anatomic Query

no code implementations9 May 2023 Ho Hin Lee, Alberto Santamaria-Pang, Jameson Merkow, Ozan Oktay, Fernando Pérez-García, Javier Alvarez-Valle, Ivan Tarapov

We introduce a novel Region-based contrastive pretraining for Medical Image Retrieval (RegionMIR) that demonstrates the feasibility of medical image retrieval with similar anatomical regions.

Deep Labeling of fMRI Brain Networks

no code implementations5 May 2023 Ammar Ahmed Pallikonda Latheef, Sejal Ghate, Zhipeng Hui, Alberto Santamaria-Pang, Ivan Tarapov, Haris I Sair, Craig K Jones

We prove the generalizability of our method by showing that the MLP performs at 100% accuracy in the holdout dataset and 98. 3% accuracy in three other sites' fMRI acquisitions.

Deep Labeling of fMRI Brain Networks Using Cloud Based Processing

no code implementations16 Sep 2022 Sejal Ghate, Alberto Santamaria-Pang, Ivan Tarapov, Haris I Sair, Craig K Jones

We propose an end-to-end reproducible pipeline which incorporates image processing of rs-fMRI in a cloud-based workflow while using deep learning to automate the classification of RSNs.

Adversarial Attacks with Time-Scale Representations

no code implementations26 Jul 2021 Alberto Santamaria-Pang, Jianwei Qiu, Aritra Chowdhury, James Kubricht, Peter Tu, Iyer Naresh, Nurali Virani

Third, we generate new adversarial images by projecting back the original coefficients from the low scale and the perturbed coefficients from the high scale sub-space.

Emergent symbolic language based deep medical image classification

1 code implementation22 Aug 2020 Aritra Chowdhury, Alberto Santamaria-Pang, James R. Kubricht, Peter Tu

In this work, we demonstrate for the first time, the emer-gence of deep symbolic representations of emergent language in the frame-work of image classification.

Automated Phenotyping via Cell Auto Training (CAT) on the Cell DIVE Platform

no code implementations18 Jul 2020 Alberto Santamaria-Pang, Anup Sood, Dan Meyer, Aritra Chowdhury, Fiona Ginty

We present a method for automatic cell classification in tissue samples using an automated training set from multiplexed immunofluorescence images.

Towards Emergent Language Symbolic Semantic Segmentation and Model Interpretability

no code implementations18 Jul 2020 Alberto Santamaria-Pang, James Kubricht, Aritra Chowdhury, Chitresh Bhushan, Peter Tu

A UNet-like architecture is used to generate input to the Sender network which produces a symbolic sentence, and a Receiver network co-generates the segmentation mask based on the sentence.

ESCELL: Emergent Symbolic Cellular Language

no code implementations18 Jul 2020 Aritra Chowdhury, James R. Kubricht, Anup Sood, Peter Tu, Alberto Santamaria-Pang

In one form of the game, a sender and a receiver observe a set of cells from 5 different cell phenotypes.
