Machine Learning-Based Analysis of Ebola Virus' Impact on Gene Expression in Nonhuman Primates

no code implementations16 Jan 2024 Mostafa Rezapour, Muhammad Khalid Khan Niazi, Hao Lu, Aarthi Narayanan, Metin Nafi Gurcan

This study introduces the Supervised Magnitude-Altitude Scoring (SMAS) methodology, a machine learning-based approach, for analyzing gene expression data obtained from nonhuman primates (NHPs) infected with Ebola virus (EBOV).

Cross-attention-based saliency inference for predicting cancer metastasis on whole slide images

no code implementations18 Sep 2023 Ziyu Su, Mostafa Rezapour, Usama Sajjad, Shuo Niu, Metin Nafi Gurcan, Muhammad Khalid Khan Niazi

Apart from this new attention mechanism, we introduce a negative representation learning algorithm to facilitate the learning of saliency-informed attention weights for improved sensitivity on tumor WSIs.

Attention2Minority: A salient instance inference-based multiple instance learning for classifying small lesions in whole slide images

1 code implementation18 Jan 2023 Ziyu Su, Mostafa Rezapour, Usama Sajjad, Metin Nafi Gurcan, Muhammad Khalid Khan Niazi

Our method initially learns representations of normal WSIs, and it then compares the normal WSIs representations with all the input patches to infer the salient instances of the input WSI.

Artificial Intelligence-Based Analytics for Impacts of COVID-19 and Online Learning on College Students' Mental Health

1 code implementation7 Feb 2022 Mostafa Rezapour, Scott K. Elmshaeuser

In this paper, we seek to understand how the COVID-19 pandemic and increase in online learning impact college students' emotional wellbeing.

A machine learning analysis of the relationship between some underlying medical conditions and COVID-19 susceptibility

no code implementations24 Dec 2021 Mostafa Rezapour, Colin A. Varady

Furthermore, this paper reflects upon conclusions made about the relationship between educational attainment, race, and COVID-19 and the possible connections that can be established with underlying health conditions, vaccination rates, and COVID-19 total case and death counts.

A Machine Learning Analysis of Impact of the Covid-19 Pandemic on Alcohol Consumption Habit Changes Among Healthcare Workers in the U.S

no code implementations12 Dec 2021 Mostafa Rezapour

In this paper, we discuss the impact of the Covid-19 pandemic on alcohol consumption habit changes among healthcare workers in the United States.

A Machine Learning Analysis of COVID-19 Mental Health Data

no code implementations1 Dec 2021 Mostafa Rezapour, Lucas Hansen

Through the interpretation of the many models applied to the mental health survey data, we have concluded that the most important factor in predicting the mental health decline of a frontline worker is the healthcare role the individual is in (Nurse, Emergency Room Staff, Surgeon, etc.
