LateralNet

Developed by Raiyan Aaijaz & Heeya Shah

LateralNet explores biologically inspired lateral inhibition and excitation in convolutional networks to improve face recognition under occlusion. By modifying ResNet-18/50 with custom PyTorch layers, the project demonstrates improved robustness when faces are partially obscured (e.g., masks, sunglasses).


Key Features

  • Custom PyTorch layers simulating lateral inhibition/excitation
  • Evaluation on the Real-World Occluded Faces (ROF) dataset
  • Improved masked-face recognition accuracy by up to 17% over baseline
  • Experiments comparing ResNet-18 vs ResNet-50 across occlusion types

Repository Structure

  • notebooks/ – Jupyter notebook containing training, evaluation, and visualizations
  • results/ – Accuracy tables and heatmaps
  • docs/ – Project report

Installation

git clone https://github.com/raiyanjaz/lateralnet.git
cd lateralnet
pip install -r requirements.txt
