Undergraduate Researcher

Center for Research Toward Advancing Financial Technology · Troy, NY

Engineered a hybrid bidirectional traceability system using Sentence Transformers and Pandas, implementing a dual-index architecture that maps unstructured PDF contract clauses to FOL representations via vector embeddings and cosine similarity. Enchanced transparency of computable contract data by developing a deterministic pipeline to classify modifications with explainable logic, validating the system's ability to align with original requirements through extensive testing on financial datasets.
