The Computer Networks Group is always looking for motivated students to work on various topics. If you are interested in any of the projects below, or if you have other ideas and are willing to work with us, please don't hesitate to [mailto:net@informatik.uni-goettingen.de contact us].

* (B) Bachelor thesis
* (M) Master thesis
* (P) Student project

=== Road anomaly and driver behavior detection ===

New! Road situations such as road traffic, roadworks and damages are critical for both human and autonomous driving. For driving (or assisted) with humans, its important to detect how the driver behaves facing dynamic road situations. This project attempts to detect anomalous road situations and driver behaviors with multi-source data mining, fusion and machine learning techniques. We expect you have some data analytics and machine learning background, as well as programming skills like Python.
Please contact Prof. Xiaoming Fu (B/M/P).


=== Assessing city livability with big data ===

* '''New!''' City livability is related to a number of factors, such as quality of life, job satisfaction, environment (green space, CO2/PM2.5, schooling/health support etc), policy, commuting time, entertainment. We utilize different data sources to understand their relation to the city livability, and analyze the coherent features which offer an evaluation framework for a city's attractiveness and livability for different types of citizens. We expect you have some statistics and machine learning background, as well as programming skills like Python.

Please contact Prof. Xiaoming Fu (B/M/P).

=== Socioeconomic analysis on commuters ===

* '''New!''' Understanding the commuter behaviour and the factors that lead to commuting are more important today than ever before. With steadily increasing commuter numbers, the commuter traffic can be a major bottleneck for many cities. The increasing awareness of a good work-life balance leads to more people wanting shorter commuting distances. The commuter behaviour consequently plays an increasingly important role in city and transport planning and policy making. This topic aims to infer knowledge from commuter data, analyzing the influence of GDP, housing prices, family situation, income and job market on the decision to commute. We expect you have some statistics and machine learning background, as well as programming skills like Python.

Please contact Prof. Xiaoming Fu (B/M/P)


=== Socioeconomic Status and Internet Language Usage ===

* '''New!''' Numerous people write social media posts and exchange messages with colleagues, friends, acquaintances or even strangers on different platforms. We would like to understand how the underlying social class membership (socioeconomic status) affects Internet users' language use, by investigating the sociolinguistic features in users' posts/messages across a multitude of datasets and their relationship to their socioeconomic status. We expect you have some statistics and textual analysis/natural language processing background, as well as programming skills like Python.

Please contact Prof. Xiaoming Fu (B/M/P)


=== Multimedia Resource Allocation for QoE Improvement by Deep Learning===

* '''New!''' Deep learning has been widely used in various real-time applications and systems. Dynamic resource allocation for multimedia (e.g. Video) to improve QoE is an interesting topic.  We need two students for this topic.  We expect you have a background in deep learning and computer network, as well as programming skills like Python and Go.

(1) one to realize and improve the system for video transmission and network configuration according to resource allocation policy; 
* You will use QUIC [https://github.com/lucas-clemente/quic-go] protocol (Go language) to implement network allocation and place the server part on AWS/other clouds.

(2) another one to implement the deep learning algorithm to design the controller for dynamic resource allocations to improve QoE.

=== Low Power, Wide Area (LPWA) technologies on smart cities===

* '''New!'''The LoRaWAN specification is a Low Power, Wide Area (LPWA) networking protocol, which is attracting a lot of attention due to their ability to offer affordable connectivity to the low-power devices distributed over very large geographical areas. In this project, we plan to exploit the LoRaWAN technologies to improve the performance of applications in smart cities. More details can be found in this [https://ieeexplore.ieee.org/abstract/document/7815384?casa_token=c3-nAktQO-AAAAAA:EHmi8hFe-HL853Kwq8Kot-mi8KPNSahLRT-4Tp0O8pdaT0mVH_DKUYPGU9onF227eKhpPPyC1436kw link] Please contact [http://134.76.18.81/?q=people/dr-yali-yuan Yali Yuan] (B/M/P)


=== Machine Learning & deep learning on electronic healthcare records===

In recent years, large amounts of health data, such as patient Electronic Health Records (EHR), are becoming readily available. This provides an unprecedented opportunity for knowledge discovery and data mining algorithms to dig insights from them, which can, later on, be helpful to the improvement of the quality of care delivery. This project will be mainly on using machine learning to analyze electronic healthcare dataset.  Please contact [http://www.net.informatik.uni-goettingen.de/?q=people/yachao-shao Yachao Shao] (B/M/P)


=== Machine Learning or Deep learning Method (Graph-based) on Recommending system or Network Traffic ===

This project will be provide students an opportunity to learn how to use machine learning or deep learning methods (espeically graph-based DL method) to solve problems in recommending systems or computer networks. The requirements include: 1) like (python) coding; 2) willing to learn DL knowledge; 3) willing to read and learn open source projects;4) Regular meeting and discussion via skype and email.
