Publications

On this page, you will find a selection of my publications. A complete list can be found on researchgate.net.

Volume Determination Challenges in Waste Sorting Facilities: Observations and Strategies
In this case study on volume determination in waste sorting facilities, we assess the effectiveness of ultrasonic sensors and address waste-specific challenges.
Transfer Meta Learning
In this paper, we present a novel meta-learning approach to find optimal hyperparameters for transfer learning processes, leveraging previously known metadata about the source task, the target task, and the pre-trained model.
Observation Time Effects in Reinforcement Learning on Contracts for Difference
This paper presents a study on reinforcement learning optimization models for automatic trading, focusing on the effects of varying observation times. Our reinforcement learning agents use a convolutional neural network (CNN) along with long short-term memory (LSTM).
The Game of Tron as A Reinforcement Learning Environment
This presentation introduces a reinforcement learning environment for multi-agent modeling based on the game Tron.
Hand Gesture Recognition in Automotive Human–Machine Interaction Using Depth Cameras
This review provides an overview of current machine learning approaches to hand gesture recognition using depth data from ToF sensors. We confirm that convolutional neural networks (CNN) combined with long short-term memory (LSTM) deliver the most reliable results.
Dynamic, Adaptive and Mobile System for Context-Based and Intelligent Support of Employees in the Steel Industry Contact data
The research project “DamokleS4.0” investigates how new technologies, such as mobile and intelligent devices or augmented reality, can be used in the context of Industry 4.0 to provide context-based and intelligent support to employees in the steel industry.
Person Tracking in Heavy Industry Environments with Camera Images
This paper presents a method for locating and tracking people in heavy industry environments using multiple cameras. Using the OpenPose network, we locate the foot points of people in each camera image and perform corresponding world coordinate transformations.

Services

Coding Days

Do you want to expand your offerings to include AI applications?

I offer customized Coding Days for companies that want to train their developer teams in AI and develop innovative solutions. In a multi-day workshop, we work together on a solution tailored to the specific needs and challenges of your company.

What you can expect:

Practice-oriented training in relevant software libraries
Hands-on coding sessions
Direct application to your projects

Seminars

Increasing digitization in almost all areas and Industry 4.0 require an understanding and implementation of the latest approaches from science and technology to remain competitive. My focus is on machine learning, especially deep learning and evolutionary algorithms.

In my seminars, I offer:

Consulting on digitization, Industry 4.0, artificial intelligence, and IT security
Current standards of data processing and software development
Training in various frameworks such as PyTorch, Tensorflow, Theano, Caffe

Workshops

To derive meaningful conclusions from large amounts of data (Big Data), appropriate analysis methods are required. Using methods from machine learning and statistics, we can identify new relationships. Depending on the nature of the data and the question to be answered, different methods have advantages:

Supervised Learning (Classification, Regression)
Unsupervised Learning (PCA, ICA, SFA, SOM, Clustering)
Reinforcement Learning (Q-Learning, A3C)
Transfer Learning (Fine-Tuning, Progressive Neural Networks, EWC, IMM)
Evolutionary Algorithms (Genetic Algorithms, Evolution Strategies, Symbolic Regression)

In workshops and individual coaching sessions, I convey customized methods for your company and your data.
