Chihuahua vs Muffin: Data-Centric AI Challenge (in collaboration with 3LC)

Overview: Can you tell a chihuahua from a muffin? Put your AI skills to the test in this exciting data-centric AI challenge, conducted in collaboration with 3LC. Unlike traditional competitions where you tweak models, here your focus is different—you’ll work with a fixed ResNet-18 model and improve performance by making your data smarter, cleaner, and more meaningful. You’ll begin with a small labeled dataset and a large pool of unlabeled images, and use the powerful 3LC platform to analyze, label, and refine your data step-by-step. Your ultimate goal? Achieve the highest accuracy on a hidden test set through smart data curation and intelligent labeling strategies. Dataset Details: Training Set 100 labeled images (50 per class) 3,579 unlabeled images Validation Set 1,000 labeled images (balanced) Used for monitoring model performance Test Set 1,184 images (labels hidden) Used for leaderboard evaluation Process & Guidelines: Participants will follow an iterative data-centric workflow: TrainTrain the ResNet-18 model using the available labeled dataset AnalyzeUse the 3LC Dashboard to: Visualize embeddings Identify misclassified and uncertain samples Understand model weaknesses Improve Data: Label selected samples from the unlabeled pool Correct incorrect labels Use sample weights to include/exclude data Retrain: Retrain the model using the updated dataset Submit: Generate predictions on the test set and submit to Kaggle Iterate: Repeat the process to continuously improve performance and climb the leaderboard Rules: Only the ResNet-18 architecture is allowed (no modifications or alternative models) Only the provided dataset can be used (no external data allowed) ImageNet pretrained weights are allowed Use of the 3LC platform is mandatory All submissions must follow the Kaggle submission format Participants must adhere to fair competition practices Any form of data leakage, misuse of test data, or rule violation will result in disqualification Stay in the loop with all event updates, important announcements, deadlines, and exclusive information.
