Machine learning for financial services

Caleb Dame

01 About Me

I'm a data scientist focused on financial services, building and shipping predictive models that hold up to real business and regulatory scrutiny: from financial crimes screening for a Tier 1 U.S. bank, to fraud detection at scale at TransUnion, to churn prediction and collections optimization for credit unions.

My work spans the full ML lifecycle: problem framing, feature engineering, model development, A/B testing, and production deployment, through to the model interpretability, documentation, and model risk validation that regulated institutions require. I'm equally comfortable wrangling multi-terabyte data in Databricks or PySpark as I am defending a model's methodology to compliance teams or designing the business strategy around its output.

Currently a Data Scientist II at SymphonyAI, supporting AI-driven sanctions and adverse media screening. Pursuing an M.S. in Artificial Intelligence at Johns Hopkins, building on a B.S. in Applied and Computational Mathematics & Economics from Brigham Young University.

Do Tabular Foundation Models Beat Trees on Messy, Real-World Data?

Do Tabular Foundation Models Beat Trees on Messy, Real-World Data?

A zero-shot benchmark of TabICLv2, a tabular foundation model that predicts by in-context learning with no per-dataset training, against tuned XGBoost and LightGBM on the CIC-IDS2017 intrusion-detection dataset (~2.1M flows, 27 classes, attacks as rare as 5 rows). Built a context-construction and prior-shift correction protocol so rare classes survive sampling and calibration is measured fairly, then ran a seeded ladder of context sizes up to the full dataset. The foundation model led on macro-F1, made decorrelated errors on rare attacks, and was the best calibrated at every context size.

HOA CC&R PDF Parser + RAG Q&A Pipeline

HOA CC&R PDF Parser + RAG Q&A Pipeline

Built an API-triggered document knowledge extraction service for a client who needed to ingest large 50 to 100 page HOA/CC&R PDFs and answer dozens of structured questions automatically. The service accepts a webhook payload, fetches the PDF from a provided URL/path, converts pages to images, runs OCR locally (Tesseract), and chunks the text into blocks where SentenceTransformer embeddings are stored in a FAISS index to enable fast and token-efficient answer retrieval. For question answering from relevent snippets, the service uses an OpenAI model for grounded answers, with quality controls to ensure answers fall in the expected JSON format.

Music-Theoretic Attention Biases for Symbolic Music Generation

Music-Theoretic Attention Biases for Symbolic Music Generation

Injected music-theory inductive biases into transformer attention for symbolic MIDI generation, encoding circle-of-fifths harmonic distance and temporal onset distance as learned bias embeddings added directly to attention logits. Trained a decoder-only transformer on GigaMIDI (~382K files, ~565M notes) using octuple tokenization across four experimental conditions (no bias, harmonic-only, temporal-only, combined) with data-fraction ablations to measure sample efficiency gains.

Reducing Reward Variance in Continuous-Control DRL via Genetic Pre-Training

Reducing Reward Variance in Continuous-Control DRL via Genetic Pre-Training

Investigated whether genetic algorithm (GA) policy pre-training of agent weights could improve stability, reduce reward variance, and potentially increase reward outcomes in deep reinforcement learning (DRL) continuous control problems using CleanRL and Weights & Biases tracking. Designed two genetic algorithm variants to evolve actor networks quickly in parallel and benchmarked the effects of further RL training compared to those with randomly initialized weights.
