Learning to Optimize (L2O)

(Start: May 2020)
While route planning for small to medium numbers of vehicles has long been reliably solved using methods of classical operations research (OR), problems with more than 100 vehicles as well as complex constraints (relevant in the area of logistics companies and fleets of large mobile care services) pose challenges that normally require very long computing time and can often only be solved approximately. Therefore the project aims at the effective and innovative combination of classical optimization methods of OR and techniques of Artificial Intelligence (AI) to overcome these challenges. [more]

IIP-Ecosphere Next Level Ecosphere for Intelligent Industrial Production

(Start: Februar 2020)
The digitalisation of industry and increasing networking are increasing the performance and complexity of technical systems and the associated processes. In the industrial environment, intelligent production (Industry 4.0) is considered to have a disruptive innovation potential, with artificial intelligence (AI) as a key technology. It is therefore imperative to facilitate SMEs' access to competences and powerful methods of machine learning and to identify and enable suitable business models. This and the integration of AI-based digital process chains into real process chains and their further development is only possible if the boundary conditions are created in the form of a suitable ecosystem. These boundary conditions are for example easy usability, comprehensive standardization as well as the provision of value-added services with a lower entry threshold. [more]

Egraphsen - Opportunities and perspectives of digital painter attribution

(Start: December 2019)
The question of the manufacturer of painted Greek vases has occupied archaeological research for more than 150 years. The digital analysis of Attic vases offers the opportunity to examine controversial practices of classical archaeology, which were previously based on expert knowledge. This is because it is not isolated criteria but characteristic combinations of features that determine the assignment of painters, which can be compiled and weighted much more easily and comprehensively with the aid of computers. In this project, in cooperation with the University of Göttingen, the assignment of the vases to painters, workshops and groups will no longer be exemplary and intuitive, but rather based on a broad data base. It is to be investigated how the criteria of attribution can be systematized, how their expressiveness can be evaluated and how the significance of the similarity networks can be historically weighted by precisely naming criteria and arguments.

Upgrade IT-Wissen

(Start: January 2019)
The goal of the project is to establish transfer and exchange structures that bring business executives and scientists from SUH together in order to mutually generate IT knowledge and IT synergies. In particular, the three IT-relevant subject areas data science, software engineering, and business engineering, which are already important topics in research and teaching at the SUH, are being addressed. The targeted forms of events are designed and tested in order to emphasize competencies for the active shaping of digitization. [more]

Data Science for all

(Start: October 2018)
The University of Hildesheim would like to combine its expertise in the field of Data Science, which has found expression in the international Master's course Data Analytics, currently the largest Data Science course in Germany, and in the establishment of a Research and Innovation Center Data Science, with the expertise in the programs located at the university in order to offer all students an educational opportunity in the field of Data Science that takes into account the different requirements and focal points of the subjects without sacrificing the teaching of the underlying methods. Its core consists of a set of two introductory courses in data science, which are structured micromodularly, i.e. in units of a maximum of 10 minutes: methodological modules, which are the same for all subjects, and example modules, which illustrate a method using an example from the respective field.

Data driven route scheduling for mobile nursing services

(Start: October 2018)
The project team consisting of the Information Systems and Machine Learning Lab (ISMLL) of the University of Hildesheim and the MediFox GmbH, the leading software provider for software solutions for mobile nursing services plans to improve the route scheduling capabilities of existing software applications. Therefore we will develop a software prototype which adopts state-of-the art heuristic optimization methods to find a ideal route and operation schedule considering all side conditions. In a second step a smart optimization model is developed, which learns how to automatically optimize respective arbitrary routing problems by employing meta learning approaches, facilitated by the huge data base of MediFox.

Automated Development of Data Analysis

(Start: June 2018)
The goal of the "Automated Development of Data Analysis" project between PSIORI GmbH and the Information Systems and Machine Learning Lab (ISMLL) is to find novel techniques to automate client specific data analysis via a meta learning approach. This enables the data scientist to offer "rapid data analysis" als a new service. These will enable clients to take a fast and cost effienct look into the world of big data and machine learing. This especially enables small and mid tier businesses to benefit from the new generation of data analysis and AI technology tools. [more]

Data-driven Mobility Services

(Start: February 2018)
Data-driven Mobility Services is a three years cooperative research project between Volkswagen Financial Services (concretely the Data Analytcs Unit 'DnA') and Information Systems and Machine Learning Lab (ISMLL) at Uni Hildesheim. As part of the contracted research cooperaton, several data analytics studies are being conducted, which includes parking availability prediction, automatic damage assessment for cars, and residual value prediction for cars. The outcome of the research done at ISMLL can be directly integrated into the backend system developed by the DnA unit, especially after the prototyping phase, during which a proof of concept is presented that highlights the effective of the solutions presented.

ÜberDax

(Start: November 2017)
The progressive digitalization of economy and society is making more and more processes observable and thus open to partial automation or at least decision support through machine learning models: in Industry 4.0 machine data can be used used to detect problems early and avoid failures or to reduce manufacturing variances and make planning more robust, in autonomous driving cars sensor and video data is already in use for simple maneuvers such as parking and will soon also be used for driving on highways, in the area of ​​e-health they help in segmenting organs and tumors or predicting how a tumor will most likely develop.

HyLAP

(Start: September 2014)
One of the major challenges of learning predictive models for complex tasks is the right hyperparameter and model selection strategy, as state-of-the-art approaches such as grid-search and random sampling require many runs of the learning algorithm, and therefore are usually conducted on large compute clusters rather than resource-restricted platforms such as robots, cars or mobile phones for instance. Therefore, autonomous hyperparameter learning strategies that are able to take into account observations of past hyperparameter performances on related problems have to be developed, enabling learning systems to learn in a fraction of the time it takes today.

Dynamic Personalization of Multimedia (MyMedia)

(ended on Feb. 2011)
We are drowning in a sea of information overload. Television channels, books and music assault our senses with far too much content. The volume of content on the internet is literally exploding. Not only traditional media but millions of individual users are putting their own content on the web. The massive popularity of YouTube is just one example of this phenomenon. So, in this flood, how do you find content that matters to you? How do you discover multimedia information and entertainment in a way that suits you personally? Isn’t there an easier way? ... [more]
