# Is Shipd.ai (Datacurve) Legit? > Source: > Published: 2026-09-15 03:22:26+00:00 # The contributor platform behind frontier AI. Compete on hard problems across STEM, earn bounties, and produce the data that drives LLMs forward. min_samples_leaf=5 is too aggressive for this dataset size. Try 10–15 to avoid overfitting on the shallow splits. Clean approach with early stopping. The predict helper is well-structured. community ## Where Kaggle grandmasters, OSS contributors, and tinkerers compete ### Top OSS contributors From the world's most impactful open-source projects. ### Top-ranked across platforms Competitive programmers and ML engineers ranked among the best on every major platform. ### A global community Engineers from 40+ countries, architecting and solving the challenges that frontier models can't. Our pool is deep. For each project, we invite top contributors to join — there's something for every skill level. Keep cooking and you'll unlock cooler and cooler projects. quests ## You’re not here to annotate data. Work on what excites you. Each unique project on Shipd is called a ‘quest’, and focuses on a specific category in STEM, including SWE, ML, DS, and more. You pick what you want to work on. ### Mars Software Engineering Tackle GitHub issues, build features, and fix bugs across the repos you care about. ### Eris Machine Learning Build and solve ML competitions that stump agents and humans alike. ### Monte Data Science Create and solve numerical computation problems that push AI reasoning to its limits. ### Explore All Disciplines New quests launch every month across dozens of STEM categories. Create an account to get notified when projects match your skills. ### Explore Issues 6 available Fix memory leak in WebSocket handler acme/realtime-server Add dark mode toggle to settings page openui/components Implement rate limiting middleware fastapi/contrib Optimize database query for user search prisma/examples Fix SSR hydration mismatch remix-run/remix Add TypeScript types for plugin API vitejs/vite ### Browse Challenges 6 active Code Generation Rubric Code Quality Math Reasoning Benchmark Reasoning Instruction Following Eval Alignment Multi-Turn Dialogue Scorer Conversation Vision-Language Grounding Multimodal Long-Context Retrieval Eval Retrieval ### Open Problems 6 available Eigenvalue Decomposition Edge Cases Linear Algebra Stochastic Gradient Descent Convergence Optimization Monte Carlo Integration Variance Reduction Statistics Sparse Matrix Factorization Linear Algebra Fourier Transform Numerical Stability Signal Processing Bayesian Posterior Sampling Statistics
