AI-assisted configuration optimization for a measurement data analysis tool (Co-supervision with industry partner IAV GmbH) [B.Sc./ M.Sc.]
(Kopie 7)
The integration of Artificial Intelligence (AI) is fundamentally transforming how tasks are accomplished, offering the potential to revolutionize workflows. This is particularly true for the use of software tools in the development processes of the automotive industry. To enhance usability and increase efficiency, these tools should also be further developed with intelligent AI features.
A concrete example is IAV Zio Insight, a tool for analyzing measurement data that allows users to individually configure the type of analysis and result visualization. These configurations are stored in the background as XML files.
Objective of the Master's Thesis:
The master's thesis aims to develop innovative approaches that enable users to create new configurations with AI support. Various approaches will be evaluated for their feasibility, including:
1. Interactive Chat Support: Development of a system that guides users through targeted interactions and prompts to assist in configuration creation.
2. Automated Suggestions: Generation of suggestions for new analysis configurations based on existing analyses or external graphics.
Ideally, the thesis will lead to the implementation of one of these approaches into the production version of IAV Zio Insight, supported by software developers at IAV, enabling direct application and a positive impact in our projects.

Diffusion Transformer (DiT) for conditional learning curve generation [B.Sc / M.Sc]
Diffusion models are typically used to generate images, possibly conditioned with text. In this thesis, a Diffusion Transformer (DiT) will be adapted to learn to generate learning curves based on hyperparameter queries, using real learning curves from benchmark problems. Essentially, this model aims to generate new multi-fidelity optimization problems and implicitly learn both the cross-correlation of multiple learning curves based on their hyperparameters and the stochastic properties of learning curves derived from their time-series characteristics.
Depending on the progress of the work, targeted generalization can also be considered, such as the iterative querying of additional hyperparameter configurations, which would be analogous to generating new image patches.
This work has several derivative applications, particularly the artificial generation of multi-fidelity optimization benchmark problems based on the properties of real curves.

Auto-PyTorch for X [BSc + MSc]
Extend, apply and refine our AutoDL tool Auto-PyTorch for new areas such as outlier detection, maintenance prediction or time series prediction. We recommend a strong background in machine learning (especially Deep Learning) and their chosen application for this work. When applying, please indicate the direction you would like to work in and provide a rough plan of how you would implement AutoPytorch in your target area.

Implementation of a new DAC benchmark [BSc + MSc].
Modelling, implementation and evaluation of DAC for any target algorithm. We recommend a strong background in RL, basic knowledge of DAC, and the target domain of your choice to be successful in this topic. Possible target domains include machine learning or reinforcement learning, MIPS or SAT solvers, and evolutionary algorithms.

Augmenting algorithm components in RL through meta-learning [MSc]
We can generate augmentation functions by meta-learning, something for the policy objective in PPO. However, it is open whether this is generally true for algorithm components in reinforcement learning, whether we could also learn augmentation ensembles, and how well these functions generalise. The goal of this work is to extend existing techniques to new algorithms and components.

Enhancing Animal Behavior Analysis via HPO in Object Tracking Algorithms – In Collaboration with Zoo Hannover [MSc]
In collaboration with Zoo Hannover, we aim to enhance object detection and tracking algorithms to monitor the maternal care of Thomson’s gazelles. We integrate Automated Machine Learning (AutoML) and Computer Vision to achieve this, focusing mainly on Hyperparameter Optimization (HPO). The project's primary objective is to improve the analysis of animal behavior using camera data. After identifying leading tracking algorithms, this master's thesis involves an in-depth examination of relevant hyperparameters specific to the corresponding tracking algorithms. The goal of this research is the strategic use of the AutoML tool SMAC to optimize the performance of the tracking algorithms, aiming for enhanced accuracy and efficiency in analyzing animal behavior.

How do Language Models fare at Optimization? [M.Sc]
The rise of Large Language Models (LLMs) in recent years has transformed the perception of Machine Learning. While their universal applicability stems from being pre-trained on diverse resources, they are most commonly utilized for tasks such as text and code generation. However, they have also demonstrated the ability to solve other challenges, including optimization problems. This thesis project seeks to explore methods to harness their potential for Automated Machine Learning (AutoML).
