Master Thesis - Deep Learning for AGV-system design!

About the project
An Automated Guided Vehicle (AGV) system is a fleet of mobile robots that automatically transport goods in a network of fixed virtual roads, designed according to the specification of the warehouse. This network must have the capacity to handle the intended traffic load without traffic jams, which is verified by running simulations. However, such simulations are time consuming, and since the design process is an iterative one, faster feedback directly translates to decreased cost. In this master thesis project, you will research how Machine Learning can be used to speed up the design process by predicting the consequences of different design choices.

Goal of the thesis
You will be given a labelled dataset with many variants of the same intersection, and your job is to develop and train a machine learning model that can predict how well each variant performs. For each variant, a simulation has been run which measures the throughput, i.e. the rate at which goods can be delivered, and this is what you will try to predict.

In the second phase of the project, you will generate new datasets for other kind of intersections. Here, the research question is whether the model can generalize to scenarios that were not in the training data.

By exploring this field of research, you will lay the foundation of new technology that will enable us to reach our goal to install more AGV systems faster

Method
The task is a form of supervised learning, and you will identify and evaluate a range of different models. Relevant metrics such as precision and recall should be calculated for each model, and you shall also explore how the choice of hyperparameters affect convergence, accuracy, and robustness. Roughly, the work will be carried out as follows

- Literature review to identify relevant models. One type of model we want you to study in particular is Convolutional Graph Networks
- Implement and train relevant models on existing data set using python libraries such as numpy, pandas, matplotlib and pytorch.
- Compare the results from the different models and give recommendation on model selection
- Generate new dataset. You will be responsible to select suitable scenarios in dialogue with domain experts at Kollmorgen, and you will use various existing python scripts to generate synthetic data, including labeling. In other words, you will not have to annotate any data manually in this project.
- Repeat training and analysis on new dataset, including testing how well the models generalize to unseen scenarios

About you
This project will require a solid background in mathematics, statistics and programming, and we are therefore primarily looking for master students from the engineering programs, such as Computer Science, Applied Physics, Applied Mathematics and similar.

However, if you are interested in Data Science and Artificial Intelligence, know python (or similar) and are not afraid of eigenvalues, we think you can take on this project if you have the right mindset.
