About & research

Parvaneh Tehrani Oskouie

Behind Polvoria is a researcher. Alongside design and build work, I do academic research in machine learning, optimization, and computer vision — the same discipline, applied to measurable problems.

Intro film
A short introduction to the work.

I work at the intersection of machine learning, metaheuristic optimization, and applied data science — turning research methods into systems that hold up under measurement.

The throughline is discipline: a clear objective, a documented method, and a number to judge it by.

Measured results, not claims

Every project is grounded in a metric. Optimization is applied where it adds measurable value — never as a buzzword.

Research & approach

One framework: optimize, then explain

Metaheuristics search the spaces gradient methods can't; machine learning does the prediction; explainability keeps every result accountable.

01 · GA

Genetic algorithms

Evolve feature subsets and thresholds — keeping what measurably helps and discarding the rest.

02 · PSO

Particle swarm

Tune model hyperparameters across a continuous space toward a single, stated objective.

03 · ML

Machine learning

Gradient-boosted trees and deep networks (LightGBM, U-Net) do the prediction.

04 · XAI

Explainable AI

SHAP attributes each prediction to its inputs, so a result can be read, audited, and trusted.

Accuracy alone is not enough. In security and remote sensing, a decision has to be defensible — SHAP turns a model from a black box into something a reviewer can interrogate, which is what makes the result usable in practice.
