Dr. Arbab Latif
Applied AI Engineer / PhD in Engineering / University Professor in AI
I build practical AI systems that connect large language models to real documents, data and workflows, and I measure how well they work.
Retrieval and RAG
Research Paper RAG
Answers questions from engineering PDFs, cites the page, and refuses when the sources do not say.
83.3%answer accuracy on 12 answerable questionsRAG Evaluation Lab
A controlled test of 12 RAG configurations that reports which differences are real and which are noise.
94%best answer score: 1024-token chunks, Granite, top-5
LLM agents
Analytics Agent
Answers business questions in plain English with guarded SQL, and every figure traces to a query.
93%execution accuracy with business definitions, up from 67%MATLAB to Python Agent
Converts MATLAB scripts to Python and checks the numbers against real MATLAB output.
4/5samples passed on the first attemptDSP Copilot
Runs signal processing from plain-English requests, with the maths done by typed tools, not the model.
6 of 6live requests passed, measured on the output signals
Signal processing and machine learning
Predictive Maintenance Agent
Turns machine signals into maintenance tickets, and code checks every number the LLM writes.
97.5%recording accuracy on unseen operating loads (CWRU)Contactless Vitals
Extracts a pulse waveform from ordinary face video using remote photoplethysmography (rPPG).
0.79correlation with a contact sensor on one real recording

About
I hold a PhD in Engineering and have spent eight years teaching AI, machine learning and computer vision at university level. My research covers digital signal processing and data analysis, and I am a US patent holder in seismic data processing.
I also bring nearly a decade of engineering and data analysis work, including MATLAB systems for instrumentation and control. That background shapes how I build AI: every project here reports real results, states how they were measured, and lists where the system falls short.
