Hack[AI]thon 2026 is a 24-hour national-level AI hackathon organized by Sphere Hive, KVG College of Engineering in collaboration with Startup Lab, Joy University. This competition challenges participants to improve model performance by focusing on data quality and curation rather than modifying the model architecture.
Challenge Overview
Participants will tackle an image classification challenge using the 3LC platform. The core task involves analyzing embeddings, strategically labeling data, and iteratively retraining models to achieve higher accuracy on a hidden test dataset. The event is designed to simulate real-world AI workflows, emphasizing data quality, experimentation, and iterative improvement.
Who Should Apply
This hackathon is open to students and developers from all colleges. While basic knowledge of Python and Machine Learning is recommended, the focus is on practical application and problem-solving. Participants must bring their own laptops and chargers.
Team Format
Teams should consist of 2 to 4 members. Cross-college teams are permitted, encouraging diverse collaboration. Each team is required to submit one final solution.
Rules & Process
Key rules include using only the provided dataset, no external datasets, fixed model architecture, and no pretrained weights. All work must be done during the hackathon duration. The process involves training a baseline model, analyzing model behavior using the 3LC dashboard, selecting and labeling important unlabeled samples, retraining the model with the improved dataset, and submitting predictions to a live leaderboard. Final ranking will be based on accuracy and approach.
Evaluation Criteria
Submissions will be judged based on model accuracy on the test dataset, the effectiveness of the data-centric approach and strategy, effective use of embeddings and labeling, experimentation and iteration, and clarity of explanation and documentation.
Prizes & Benefits
A total cash prize pool of ₹35,000 is available for top-performing teams. Additionally, all participants will receive certificates, a free .xyz domain, swag kits, goodies, and valuable networking opportunities with AI mentors and peers. This is a hands-on experience with Data-Centric AI tools.
How to Apply
Registration for HackAIthon 2026 closes on May 5, 2026. Interested teams should register via the official event page linked above.
