Experience
AI Researcher – I
AMERICAN EXPRESS AI LABS
• Table Structure Recognition in Unstructured Documents: Designed and trained a CNN-LSTM based model & Image Captioning model for predicting the table structure, applied to financial statements (PDFs) to extract variables, resulting in a potential benefit of $6M. • Information Extraction from Receipts: Designed and trained a graph convolutional network with image & text embeddings to extract entities (Merchant Name, Merchant Address, receipt date, etc.). • Bank Statement Parsing: Built a hybrid rule-based & learning based method to extract transactions and ownership information from various bank statements, outperforming existing vendor-based solutions.
Research Intern
AMERICAN EXPRESS AI LABS
• Question Answering on Financial Statements: Built an end-to-end pipeline consisting of Retrieval + QA, creating a dataset for QA on financial statements and fine-tuning an existing BERT-QA model.
