Medical Device Failure Classification (NLP Project) – Developed an automated system to classify technology-related failures in medical device safety reports using the FDA MAUDE database. Processed and cleaned 50,000+ unstructured incident reports and built machine learning and NLP models (TF-IDF, Logistic Regression, SVM, and BERT-based models) to distinguish computing vs. non-computing failures. Applied confidence-threshold filtering (0.70) to flag low-confidence cases for manual review, performed error analysis and model validation, and generated summary reports and dashboards to support clinical safety and decision-making.
