Projekthistorie
- Develop, evaluate and optimize advanced AI/LLM systems for economic decision-making, including benchmarking, reasoning assessment, reliability checks and error analysis.
- Improve model accuracy and domain-specific performance through prompt engineering, RAG/LLM optimization techniques and deep research rubrics.
- Build a predictive model identifying attrition risks among young customers and partner with the national banking association to design a data-driven strategy for long-term customer retention.
- Develop and evaluate data models (XGB) for automated customer targeting across 40 million accounts, including KPI design and impact measurement to optimize sales channels.
- Project in AI: Lung Disease Detection using X-Ray Images
- Develop deep learning and classic ML (SVM, XGB) models to detect lung diseases from 21,000 X-rays, achieving a 95% macro F1-score with the best TensorFlow transfer learning model.
- Deploy a Streamlit web app on AWS Cloud enabling real-time predictions and Grad-CAM visualizations from uploaded chest X-rays.
