Overview

Assignment of theses

The final theses in the AG Riehle are usually not pure literature theses but include the development of small prototypes or the collection and analysis of data. Below you will find a list of suggested topics. It is also possible to submit your own topic suggestions, as long as they can be assigned to one of the following topics:

Sensors and Internet-of-Things (LoRa, etc.)

Please refrain from inquiries that cannot be assigned to any of the above areas.

Topics for theses

Development and Evaluation of a Hybrid Chatbot Architecture

For: Bachelor, Master

Traditional chatbots often have limited capabilities in natural language processing, as they rely on predefined rules to understand the user input and respond accurately. In the recent past, Large Language Models (LLMs) have been increasingly integrated into chatbots due to their strengths in processing and generating natural language. The use of LLMs, however, is not without drawbacks, since they tend to produce hallucinations, meaning inaccurate, factually incorrect, and even harmful responses. The goal of this thesis is to implement and evaluate a hybrid chatbot architecture that utilizes both, traditional chatbot techniques and LLMs, to mitigate their respective weaknesses.
