Seminar Software Engineering

Developping software components using machine learning requires a workflow of tasks like data cleaning, features engineering, model selection, etc. that needs to be regularly performed, monitored and tracked. The current popularity of machine learning methods have lead several companies to develop new workflow orchestration and model management tools such as DVC, mlflow, kubeflow, etc. therefore surveys are currently missing. The goal of this seminar is gain an overview of the different tools and methods used to manage data science workflows.

Bachelor - literature overview of workflow orchestration and model management systems

The process of building software components using machine learning methods can be seen as a workflow of more or less tedious tasks (a directed acyclic graph, or DAG) which can be (partially) automated. In the last years several automated tools have emerged (as known as AutoML). In this seminar, the goal is to gain an overview of the features proposed by AutoML tools and discuss their use by data scientist.

Bachelor - literature recherche: features of AutoML

A self-adaptive system (SAS) is capable of adjusting its own behavior in response to any change in its operating environment. It is able to automatically adapt at runtime by adjusting its own parameters or components of the system in order to cope with the dynamic surrounding environment. However, adaptation actions should be identified as per the particular change in the environment, i.e. “What kind of change is required?”. The aim of this literature study is to address the scope of dynamic integration of the new parameter or new component at runtime in SAS. The following set of questions is essential to fulfilling this literature study.

•  Which adaptation techniques are better?
•  How much reliable and safe it is?
•  Is it feasible to implement combination of techniques in SAS?
•  What are the impacts and cost factors?
•  How to increase the performance of the SAS with adaptation techniques?

The following set of questions is essential to fulfilling this literature study.

• How diversity can decrease the common-cause fault (CCF)?
• Which techniques are required to assess diversity?
• What needs to be done to improve safety and security in MVS?
• Limitation of diversity application in different industrial cases
• How to choose variants in MVS?

Advancement of technology and their impact on the real-world can be assessed by how safe it is. It is a primary role of a safety engineer to assess the risk via a process relevant data and learning from past lessons. Due to advanced and autonomous technology, a study for continuous and dynamic risk assessment is required. Aim of this literature study is to address the dynamics of risk and AI-based assessment techniques. The following set of questions is essential to fulfilling this literature study.

•   What are the dynamics of risk?
•   Which quantitative/qualitative risk assessment techniques are available?
•   How AI-based risk analysis is feasible?
•   What is the impact of human factors on AI-based risk assessment?
•   Which AI-techniques can be useful for risk assessment?

Twitter user Paul Franks tweeted at Musk on Friday night with a request for Tesla: “Can you guys program the car once in park to move back the seat and raise the steering wheel? Steering wheel is wearing.” Musk responded: “Good point. We will add that to all cars in one of the upcoming software releases.” And they did! Your job in this seminar topic is to explain how this was possible with the help of the continuous practices, i.e., continuous integration, delivery, and deployment.

Integrating Agile Software Development (ASD) with Software Product Line Engineering (PLE) has resulted in proposing Agile Product Line Engineering (APLE). The goal of combining both approaches is to overcome the weaknesses of each other while maximizing their benefits. However, combining them represents a big challenge in software engineering. Your job in this topic is to investigate the up-to-date methodologies and approaches for APLE and to assess their feasibility.

Achieving a safe autonomous vehicle is not something that can be solved with a single technological silver bullet. Rather, it as a coupled set of problems that must be solved in a coordinated, cross-domain manner. Your job in this seminar is to investigate the challenges that face safety arising from different interrelated fields.

How does the agile Method Scrum look like in a remote Setting? This question should be answered based on the literature suggestions and additional literature identified in a small literature search. The seminar should summarize existing experiences and highlight challenges caused by the remote setting, and solutions (adaptation to the original Scrum) to cope with those challenges. In the focus should be literature dealing with a full remote setting, meaning that all team members are working remotely (e.g., not only a sub-team working remotely from another country.). Results should provide an overview to agile teams how to adapt their Scrum approaches to deal with remote collaboration, which could be a nice guiding document in the current situation. Experience with Agile methods (e.g., in lectures process management) would be ideal

How does effective and efficient communication of an agile team looks like in a remote setting?

The analysis of Deep neural networks (DNN) is crucial to ensure the quality of the trained model. In order to find different and test different input classes, multiple methods exists. The student should investigate, how the methods described in the reference list work and how they are interrelated. Beyond the given papers, further work should also be examined.

The release of autonomous vehicles requires a sufficient degree of testing. The performed testing has to fulfill certain characteristic to reach the wanted level of confidence. Current research is aiming to determine of required testing. As argumentation framework safety cases of autonomous vehicles should be used. The safety case will determine which V&V activities during development time as well as runtime mechanism are required to assure a sufficient level of confidence, even in the presence of unknown events and uncertainties. Among these activities this work should identify and compare which implications the upcoming safety standards for autonomous vehicle impose on testing. (Work split for students: one for safety for AV in general and one with testing requirement focus) Out of scope: explaining how simulations can be setup.

Autonomous vehicle will require simulations to be tested. The student should identify which challenges exist and how solution approaches tackle them. The challenges include test specification, execution as well as the definition of how to integrated testing knowledge from component level testing to the vehicle level. The work should also explain how machine learning can be used to interpret simulations. Out of scope: explaining which level of testing is necessary for safety cases.
