Data Scientist • Technical • medium

How would you handle severe class imbalance in a dataset used for defect detection in semiconductor wafer manufacturing?

#Class Imbalance #Computer Vision #Data Augmentation #Loss Functions

Data Scientist • Technical • medium

What is Focal Loss, and how does it address extreme foreground-background class imbalance in object detection tasks compared to standard Cross-Entropy?

#Computer Vision #Loss Functions #Object Detection

Data Scientist • Technical • medium

Describe the architecture of a Two-Tower Recommender System. How do you handle negative sampling during training to ensure the model learns effectively?
