Deep Learning Model for Invasive Ductal Carcinoma Detection in Histopathology Images

Dylan Jayabahu (sole author)

IEEE CCECE 2025 IEEE Xplore

Introduces a novel computer-aided diagnosis (CAD) system for detecting Invasive Ductal Carcinoma (IDC) in histopathology images using advanced deep learning techniques. The system incorporates innovative sliding window-based heatmaps and a unique oversampling technique that extracts patches from homogeneous regions in whole-slide images, addressing class imbalance while maintaining biological integrity. Achieved state-of-the-art performance with 89.06% balanced accuracy and 86.68% F1-score, outperforming existing models in the literature.

Innovation: Novel sliding window heatmaps and homogeneous region oversampling
Performance: 89.06% balanced accuracy, 86.68% F1-score (SOTA)
Venue: IEEE Canadian Conference on Electrical and Computer Engineering (CCECE)
Location: Vancouver, Canada (May 2025)
Impact: Clinical tool for pathologists with interpretable heatmap visualization

Dataset for Real-World Human Action Detection Using FMCW mmWave Radar

Dylan Jayabahu, Parthipan Siva

CVIS 2024 JCVIS

Presents a real-world mmWave radar dataset for human action detection with applications in healthcare and home automation. Unlike existing research limited to controlled environments, this work captures natural activities across 28 residences, focusing on privacy-preserving sensing technology for aging-in-place monitoring. Developed and evaluated CNN-based models for action detection, demonstrating the challenges and potential of real-world radar-based human activity recognition systems.

Dataset: 28 homes, 458 sit-down and 454 stand-up actions
Technology: TI IWR6843AOP FMCW mmWave sensor with 3D point clouds
Model: 3-layer CNN with sliding window detection approach
Presentation: Presented at CVIS 2024, University of Waterloo
Innovation: First real-world dataset vs. controlled simulations
