my qualification theses

Control System of an Autonomous Robot for Solving Multi-objective Tasks

The thesis proposes multiple approaches that improve the speed of learning in the context of reinforcement learning. It shows multiple ways in which prior knowledge can be utilized. It considers both external objectives and intrinsic motivational signals in a single multi-objective motivational system.

Applications of Artificial Intelligence Methods to Design and Control of Robotic Systems

The thesis deals with the application of artificial intelligence methods – especially of genetic algorithms and genetic programming – to design and control of robotic systems. It proposes several adaptive mechanisms and shows in what ways these improve upon vanilla genetic programming.

Automatic Speech Recognition System

The thesis deals with automatic speech recognition systems. It develops and verifies a system for recognition of isolated speech units, based on artificial neural networks.
