Nouh Khouyi Etbar Data Science student

I build AI systems that can be audited: LLMs for banking, calibrated models for finance, and data for cities.

Final year at UPV, now at IMT Atlantique. Based in València, always open to new projects and to working in any environment.

Anomalous Diffusion for Financial Regime Detection

Jan – May 2026Co-authored, team of 6PyTorch, MLflow, Streamlit

We treated market prices as particles moving through a medium and asked when their diffusion regime changes. A multi-task Conv1D + BiLSTM network, trained on 100k synthetic trajectories, locates the changepoint and classifies the regime at the same time.

On S&P 500, IBEX 35 and crypto data it matched 12 of 15 known stress events, up to 45 days early. A Bayesian uncertainty layer turns each detection into a credible interval and a cost-sensitive action, so a person reviews the output instead of trusting a bare score.

Code private. Paper in preparation.

Each detection maps to one action, weighted by the cost of being wrong.

Retrieval system for tier-1 banks

GPTadvisor2026

I own this system end to end as the only technical lead and the client's point of contact. In banking every answer has to be traceable to a source document, so evaluation is built into the pipeline from the start.

2025Project lead, team of 4Samsung Innovation Campus

Neighbours and community gardens report problems on Telegram, by text or voice. Whisper transcribes, Gemma (via Ollama) extracts the who, where and how urgent, and the result lands in Supabase and a Neo4j graph as tasks with owners.

The Secret Beneath the Soil

2025Real sensor data from Agro4Data, under NDA

We went looking for real, messy data. Field sensors plus AEMET and SIAR weather records gave us five-day soil-moisture forecasts, showing a farm could run fewer sensors.

About

Nouh Khouyi in a Sigma Data Club T-shirt, talking with a club member at an event

Five years ago I didn't know if I'd study medicine, computer science or biology. I followed my instinct into data science, and the path cleared as I walked it.

In 2025 UPV gave me its Top Academic Performance Award. What I enjoy most is work with real people on the other end: a farm-tech founder sharing his sensor data, a city planning its transport, a bank that needs every answer traced to a source.

Outside work I train, read, and keep one stoic rule close: do what depends on you, and accept what doesn't.
