Knowledge distillation for proteasomal cleavage prediction in a vaccine design framework
The objective of the thesis is to apply techniques from knowledge distillation to derive a student model from an available cleavage predictor (binary classification on sequence data) that is suitable to be embedded in a vaccine design framework based on mixed-integer linear programming and with better performance than the linear predictor currently employed.

Positive-unlabeled Learning on Text Data
Positive-unlabeled learning (PU-Learning) describes binary classification tasks in which the data has annotated positive labels but no negative labels. This is a special case of semi-supervised learning and is related to one-class-classification. It is a common problem, especially in tasks with many observations, where it is impossible to annotate all samples with labels and the focus lies on the positive labels. Within this thesis, PU Learning should be applied in a text classification setting on a data set provided by the Fraunhofer IMW, one of the two Fraunhofer Institutes involved in this project.
The master student is expected to familiarize with the different PU Learning approaches and apply the most promising on an internal dataset provided by the Fraunhofer IMW.
Take a look at this exposé for more information on this topic.
Learning Set and Irregular Data using Deep Meta-learning
Meta-learning, also known as “learning to learn”, intends to design models that can learn new skills or adapt to new environments rapidly with a few training examples. There are three common approaches: 1) metric-based: learn an efficient distance metric; 2) model-based: use (recurrent) network with external or internal memory; 3) optimization-based: optimize the model parameters explicitly for fast learning.
A typical machine/deep learning algorithm, like regression or classification, is designed for fixed dimensional data instances. Their extensions to handle the case when the inputs or outputs are permutation invariant sets rather than fixed dimensional vectors are not trivial. However, most available data are unstructured and set such as point cloud, video/ audio clip, time-series data. Learning representation of unstructured data is very valuable in many domains such as health care and has a high impact on machine, deep learning research areas.
Here, we offer different research topics as master thesis, for more information please visit Google doc.
Deep Reinforcement Learning
Deep reinforcement learning combines deep neural networks with a reinforcement learning structure that enables agents to learn the best actions possible in a virtual environment in order to attain their goals. That is, it unites function approximation and target optimization, mapping state-action pairs to expected rewards.
Reinforcement learning refers to goal-oriented algorithms, which learn how to attain a complex objective (goal) or how to maximize a particular dimension over many steps; for example, they can maximize the points won in a game over many moves. DRL algorithms can start from a blank slate, and under the right conditions, they achieve superhuman performance.
Here, we offer different research topics as master thesis including:
1) Investigating DRL with other ML algorithms such as meta-learning, life-long learning, active-learning, generative model, Bayesian deep learning. 2) Systematically study and benchmarking the value function, state and reward function, actions, and different hyperparameters 3) Study and benchmarking the policy evaluation techniques 4) Investigating the application of DRL in computer vision or NLP.

A Neural Network-based Approach for Feature-weighted Elastic Net
In this Master thesis you will implement the recently proposed fwelnet algorithm into a neural network. fwelnet can be defined in a neural network with either conventional layers or using cvxlayers. In simulation studies you will compare the two implementations against each other and also against an existing R package. You will further investigate the model performance when using more complex additive predictors or deep neural networks to feed information into the model parameters.

Deep Distributional Regression
Deep Distributional Regression (DDR) extends classical statistical regression models such as generalized linear or additive models as well as generalized additive models for location, scale and shape to regression models with potentially many deep neural networks. In this Bachelor thesis you will investigate the performance of the one DDR framework in a large simulation and benchmark study and thereby help to generate new ideas and suggestions for improvement in the field of DDR.

Semi-Structured Deep Distributional Regression Penalties
The Semi-Structured Deep Distributional Regression (SDDR) framework extends classical statistical regression models such as generalized linear or additive models as well as generalized additive models for location, scale and shape to regression models with potentially many deep neural networks in the linear predictor of each parameter. SDDR allows for different penalties including L1-, L2- or other custom penalties like smoothing penalties. In Deep Learning different other penalties such as L0-penalties are available for neural networks. In this thesis you will extend the SDDR framework by implementing new penalties and investigate the performance of your implementation in simulations and benchmarks.

Analysis of Overfitting Effects During Model Selection
In this master thesis you will analyze, whether model selection/hyperparameter tuning can suffer from overfitting. For details refer to the Google doc.
Hierarchical word embeddings using hyperbolic neural networks
In this master thesis you will investigate recent advancements in Geometric Deep Learning with a specific focus on Natural Language Processing. Geometric deep learning operates in spaces with non-zero curvatures. Fields of application include computer vision (three-dimensional objects), genetics, neuroscience or virtually any kind of graph data. Especially hyperbolic deep learning is currently of interest to the machine learning community. These models are particularly promising when there are hierarchical structures in the data. For details refer to the Google Doc.
R package for Counterfactual Explanation Methods
Machine learning models have demonstrated great success in many prediction tasks on the cost of being less interpretable. A useful method for explaining single predictions of a model are counterfactual explanations or short counterfactuals. In this master thesis you will make yourself familiar with the literature on counterfactual explanation methods and will integrate some of the methods in the counterfactuals R package. Furthermore, you will evaluate the performance of the integrated methods and their runtimes.

Analyzing the Permutation Feature Importance
The permutation feature importance (PFI) assesses the importance of features by computing the drop in out-of-bag performance after permuting a considered feature. It was initially introduced for random forests, although the main idea can also be performed in a model-agnostic fashion. However, many properties are not well-studied and several research questions are still open. The aim of this thesis is to study the model-agnostic PFI and conduct empirical studies to answer some of these unanswered research questions.
For details refer to the Google Doc.
Visualization of ML Hyperparameter Dependencies
Starting from a large collection of performance data from machine learning experiments, the goal of this thesis is to gather new and interesting insights into interactions between hyperparameters and their performance on a given dataset or across several datasets. The goal of the thesis is to combine classical visualizations and interpretability techniques to improve the analysis of such datasets.

Uncertainty Estimation in Deep Learning-based Hybrid Localization
This topic is in collaboration with the Fraunhofer IIS, Nürnberg, and aims to develop a robot system that can (self-)localize in large-scale indoor environments. The robot platform is equipped with stereo and monocular cameras, IMUs and UWB transmitter. The goal is to predict an accurate pose of the robot from the sensors with deep learning based models, and use uncertainty quantification to estimate the uncertainty in the data and the models. The main part will be to estimate the epistemic and aleatoric uncertainty, e.g., using SWAG or Monte Carlo dropout. These uncertainties can be used to improve the pose accuracy.

The disputation of a thesis lasts about 60-90 minutes and consists of two parts. Only the first part is relevant for the grade and takes 30 minutes (bachelor thesis) and 40 minutes (master thesis). Here, the student is expected to summarize his/her main results of the thesis in a presentation. The supervisor(s) will ask questions regarding the content of the thesis in between. In the second part (after the presentation), the supervisors will give detailed feedback and discuss the thesis with the student. This will take about 30 minutes.
- How do I prepare for the disputation?
You have to prepare a presentation and if there is a bigger time gap between handing in your thesis and the disputation you might want to reread your thesis.
- How many slides should I prepare?
That’s up to you, but you have to respect the time limit. Prepariong more than 20 slides for a Bachelor’s presentation and more than 30 slides for a Master’s is VERY likely a very bad idea.
- Where do I present?
Bernd’s office, in front of the big TV. At least one PhD will be present, maybe more. If you want to present in front of a larger audience in the seminar room or the old library, please book the room yourself and inform us.
- English or German?
We do not care, you can choose.
- What do I have to bring with me?
A document (Prüfungsprotokoll) which you get from “Prüfungsamt” (Frau Maxa or Frau Höfner) for the disputation.Your laptop or a USB stick with the presentation. You can also email Bernd a PDF.
- How does the grading work?
The student will be graded regarding the quality of the thesis, the presentation and the oral discussion of the work. The grade is mainly determined by the written thesis itself, but the grade can improve or drop depending on the presentation and your answers to defense questions.
- What should the presentation cover?
The presentation should cover your thesis, including motivation, introduction, description of new methods and results of your research. Please do NOT explain already existing methods in detail here, put more focus on novel work and the results.
- What kind of questions will be asked after the presentation?
The questions will be directly connected to your thesis and related theory.
