Lukáš Raszka

I work on data-driven methods for industry, from machine learning and machine vision to predictive maintenance, digital twins and industrial analytics, with a focus on results that hold up in real operation.

Research

My work asks a practical question: when does a model that scores well in the lab keep working on a real machine, a new plant or a different year? I evaluate methods under deployment conditions and report how uncertain the answer is.

The topics below are only a selection of what I work on. Every machine, process and dataset is unique, so I gladly take on problems that are not listed here, even when the solution is not yet clear.

Reliable machine learning for industrial time series

Anomaly detection and forecasting with calibrated uncertainty, evaluated under distribution shift, data leakage and limited labels, so reported accuracy reflects what happens in operation.

Predictive maintenance and condition monitoring

  • Vibration-based anomaly detection for CNC machining, including commissioning on new machines without labelled faults
  • Remaining useful life estimation and transfer between machines
  • From tool-wear prediction to cost-aware replacement decisions
  • Virtual sensors and fault detection for wind turbines, photovoltaics and HVAC systems

Machine vision and quality inspection

Camera-based and 3D-scanning inspection, focused on small, frequently changing production batches where fixed inspection setups are impractical, and in-situ imaging for additive manufacturing.

Digital twins and decision support

Digital twins that connect measured data with simulation, and decision support for remanufacturing and end-of-life recovery that carries uncertainty through to the decision.

Industrial data and cybersecurity

Benchmarks and data audits for anomaly detection on industrial control systems, and measurement of exposure and exploitation across industrial security advisories.

Industry, energy and sustainability analytics

Data-driven studies of manufacturing, energy and emissions, with colleagues from the economics and management side of the department.

Projects

Vision-based leak detection in pressurised gas cartridges

A machine-vision system estimates the leak rate of a submerged component from the number and size of the bubbles escaping from it. It targets sealing defects in mass-produced cartridges used in consumer and safety products.

Machine vision, bubble analysis, leak testing, quality control

Defect detection for small production batches

Planned work on flexible inspection of parts made in batches of a few thousand pieces, comparing camera-based and 3D-scanning approaches.

Collaboration

We are open to collaboration in many forms: joint research and projects, shared experiments and data, co-authored publications, studies, prototypes and pilot projects. Our scope is broad, and we are happy to work with both academic partners and companies.

Academic partners

Joint research and project proposals, shared experiments and data, co-authored publications and exchange of ideas across disciplines.

Companies

Studies, prototypes and pilot projects tailored to your process and equipment, from measurement and inspection to data analysis and digital tools.

The topics listed on this page are only a part of what we do. Every machine, process and dataset is unique, so we gladly take on problems that are not described here, even when the solution is not yet clear.

Write to me at lukas.raszka@vsb.cz and I will gladly go through everything with you. No question is a bad question, so send whatever you have, even a rough idea.
