    Furina ML trains real Scikit-Learn, XGBoost, and LightGBM models on uploaded CSV files up to 50 MB, ensuring that every metric and feature weight is computed on actual data.

    Leak-Free Scikit-Learn Pipelines

    Preprocessing operations such as imputation, scaling, and one-hot encoding are bundled within a scikit-learn Pipeline, fitted strictly on training splits to prevent data leakage.

    Full Artifact Ownership

    Models are exported as standalone .joblib files, allowing for immediate real-world inference without dependencies on the web platform.

    Real-World Use Cases & Applications

    Furina ML is ideal for:

    • Data scientists and analysts prototyping baseline models on tabular datasets without writing boilerplate Python.
    • Clinicians, researchers, and domain experts evaluating predictive algorithms on empirical data without coding.
    • Developers needing exportable production-grade .joblib pipelines trained without subtle data leakage.

    How It Works: Step-by-Step Workflow

    Furina ML’s workflow includes:

    1. Data Ingestion & Profiling: CSV upload with auto-detected delimiters and multi-encoding support.
    2. Data Preprocessing & Cleaning Recipes: Step-by-step transformations with dry-run previews.
    3. Model Training & Pipeline Composition: Select from 19 machine learning algorithms and configure hyperparameters.
    4. Evaluation, Explainability & Deployment: Inspect rigorous evaluations and export models as .joblib files.
