You will develop, test, and improve machine learning models for AI training projects. The work combines Python engineering, data analysis, experimentation, technical documentation, and recommendations based on model results.
- Design, develop, and refine machine learning models using Python and libraries such as scikit-learn, TensorFlow, or PyTorch.
- Analyze large datasets and use MongoDB to store, manage, and retrieve data for training and validation.
- Build data pipelines and preprocessing workflows that support model training and inference.
- Evaluate models, tune hyperparameters, and benchmark results using suitable performance measures.
- Work with other contributors to find areas for improvement and implement reliable solutions.
- Document methods, experiments, results, and technical recommendations so the work can be repeated and reviewed.
- Provide data-based insights and recommendations from machine learning results.
