Transfer-Learning Backbone Bake-Off for Retail Product Tagging
Overview
What this challenge is about.
You receive 80,000 retail product images tagged with multiple labels from a 250-tag taxonomy. Use each of the three pretrained backbones via two transfer strategies: (1) linear probe on frozen features, (2) full fine-tune of the last 4 layers. Evaluate macro-F1 on a 5,000-image held-out set, training time, and inference latency on a single T4 GPU. Discuss the trade-off and recommend one (backbone, strategy) pair. Pay extra attention to how the three backbones differ on the long-tail tags (tags with under 50 training images).
The Brief
What you'll do, and what you'll demonstrate.
Pick the best (pretrained-backbone, transfer-strategy) pair for a multi-label retail product tagger, with long-tail-tag performance treated as a first-class metric.
Earning criteria — what you'll demonstrate
- Apply multiple transfer-learning strategies on the same downstream task
- Compare CNN, self-supervised, and contrastive backbones honestly
- Evaluate long-tail multi-label performance as a separate first-class metric
- Recommend a backbone + strategy under real compute constraints
