Multimedia Big Data Studies:

My objective is to implement a framework that enables researchers of many research field to extract useful data from user-generated content to perform field studies.

Framework - pySPACE:

pySPACE is the abbreviation for signal processing and classification environment written in Python which is supporting parallelization and intuitive configuration (based on YAML).

I am not the original developer of pySPACE but I am the lead developer and I contributed the major parts to it like documentation, usability, numerous algorithms, tuned performance, classification, regression, evaluation metrics, parameter optimization, etc. Furthermore, I was responsible for making this software open source.

Currently, I am working on optimizing processing chains. One of my approaches uses deep learning on EEG data and the other is to integrate domain/expert knowledge and the optimization library Hyperopt into pySPACE.

Support Vector Machines (SVMs):

Due to their generalization capability on few data with high dimensions, the SVM is a common classifier in EEG data processing. I encountered numerous variants of this algorithm and derived general and intuitive concepts how these variants are connected. The approaches could be used to improve the understanding of these algorithms and to easily teach a class of algorithms to students. My concept included the (smooth) connections to linear discriminant analysis, support vector regression, relative margin machine, one-class SVM, and the online passive-aggressive algorithm. Recently, I compared different possibilities of online learning SVMs which consider resource limitations.


To avoid that a complex data processing chain is relying on artifacts it is crucial to determine how it interacts with the data in total. I implemented a generic approach to decode (and visualize) these processing chains. As a side product, I developed and compared algorithms which are capable of reducing the segment length and the number of sensors used in the processing of segmented time series data from multiple sensors (e.g., EEG and robotics data). Currently, I am working on improving the interpretability with the help of source localization methods.

Intelligent Man-Machine Interaction (IMMI):

I contributed to the proposal of this project and I have worked in IMMI from 05/10 to 04/15 and in the follow-up project, RECUPERA-Reha. My tasks involved the optimization, descriptive analysis, and online adaptation of data processing chains for electroencephalographic (EEG) data. One task was to detect the perception of rare infrequent important events in contrast to the perception of more frequent but irrelevant in the very noisy data. The other task was to predict upcoming movements by detecting the movement preparation in the EEG. Most parts of my thesis are results from my work in this project and they are related to support vector machines, decoding of EEG data processing chains, and the processing optimization with the framework pySPACE.


Even though my main responsibility has always been on EEG data processing, I regularly support colleagues with mathematical or machine learning problems in robotics. This includes processing chain construction/optimization, soil detection, sensor fault detection, outlier detection, underwater vehicle movement modeling, reinforcement learning, automotive control, etc.
