Welcome

My name is Hossein Jafarinia

I am a researcher with a deep interest in Machine Learning, Reinforcement Learning, Medical Image Analysis, and Computer Vision. My work has primarily revolved around developing novel architectures and methods for Whole Slide Image (WSI) Classification and Multiple Instance Learning (MIL), with applications in cancer detection and localization. Over the course of my academic journey, I have collaborated closely with research teams, mentored interns, and contributed to significant publications in my field.

Research Experience

RIML Lab at SUT

Tehran, Iran
Supervision: Dr. Mohammad Hossein Rohban
Sep. 2021 - Present
Dedicated my entire Master’s program to this lab, focusing on developing architectures, theories, and frameworks for gigapixel images. I led literature reviews, intern mentorship, and team management, contributing to both theoretical and practical advancements. Published two papers (AAAI 2023 workshop and ECCV 2024) with state-of-the-art results in WSI classification. Currently, I am researching WSI classification techniques with an emphasis on data augmentation, as well as exploring Neural Collapse in neural networks.

ML Lab at SUT

Tehran, Iran
Supervision: Dr. Mahdieh Soleymani Baghshah
Jun. 2024 - Present
Currently studying the effects of the Neural Collapse on the generalization and robustness of deep neural networks. This research aims to develop improved techniques to understand this complex concept better.

RIV Lab at BASU

Tehran, Iran
Supervision: Dr. Hassan Khotanlou
Jul. 2019 - Sep. 2020
During my undergraduate studies, I worked on advancing medical vision applications. I mastered both classic computer vision techniques and modern concepts, which led to developing a successful malaria blood cell detection model. I modified the state-of-the-art RetinaNet model to achieve exceptional performance in this challenging task.

Projects

  • Implementation of SAC Algorithm for Offline Reinforcement Learning
    Implemented the Soft Actor-Critic (SAC) algorithm to improve offline reinforcement learning performance, with extensive evaluation on benchmark datasets.

  • Contrastive Language-Image Pretraining (CLIP) for Histology WSIs
    Adapted OpenAI’s CLIP model for histology whole slide image classification, enabling the model to leverage text-image pairings for improved image understanding.

  • Cancer Mutation Detection with Microarray Data
    Developed a machine learning pipeline for detecting cancer mutations based on microarray gene expression data.

  • Small Molecule Quantum Feature Extraction and Target Protein Docking
    Focused on quantum feature extraction in small molecules and performed docking simulations to predict interactions between target proteins and small molecules.
