Background:
6G-XCEL and Modelar DB
The 6G-XCEL project includes researchers from across the EU and the US and will develop a reference framework for AI in 6G that will pave the way toward global validation, adoption, and standardization of AI in 6G. Using the latest AI algorithms and data compression techniques as a starting point, 6G-XCEL will develop the Decentralized Multi-party, Multi-network AI(DMMAI) framework. Work on DMMAI will include the development of reference use cases, data and model repositories, curated training and evaluation data, AI-based methods and solutions for 6G, and technologies that enable use of DMMAI as a benchmarking platform for future AI solutions for 6G networks. More information about 6G-XCEL can be found at: https://www.6g-xcel.eu/.
To manage the extreme amounts of time series data in 6G-XCEL, the open source TSMS Modelar DB developed by Aalborg University will be used. Modelar DB provides lossless and lossy compression by fitting mathematical functions, e.g., constant or linear, to time series within a user-defined error bound(possibly zero). This compression is combined with a scalable query processing engine that can execute queries on the compressed representation to yield a unique combination of high compression, fast data ingestion, and scalable aggregate query processing. Modelar DB is implemented in Rust and uses Apache Data Fusion for query processing, Aparche Arrow for in-memory analytics, and Delta Lake with Apache Parquet for storage. More information about Modelar DB can be found at: https://github.com/skejserjensen/Modelar DB. The most recent version of Modelar DB can be found at: https://github.com/Modelar Data/Modelar DB-RS.
Research content:
In the 6G-XCEL project, Aalborg University will work on extending and optimizing Modelar DB for managing time series in 6G-XCEL's DMMAI framework. Thus, the purpose of this position is make Modelar DB efficiently support network data and low-powered network devices. As part of this, Modelar DB must be optimized for the domain specific requirements of 6G networks, e.g., hard real-time stream processing, and tighter integration with sensors and wireless access points. Modelar DB also lacks compressed representations specifically optimized for communication data, thus the development of such will also be part of the position.

Requirements:

• Ph D in computer science
• Excellent scientific background and publication record
• Demonstrated ability to work independently as well as in a team
• Excellent communication skills in English, oral as well as written
• Good low-level software development skills

Advanced experience in one or more of the following areas:

• Time series compression(lossy and/or lossless)
• Big data management and analytics
• Real-time stream processing
• Implementation of database management systems

Experience with the Rust programming language and the Apache Arrow ecosystem of libraries is an advantage.
Responsibilities:

• Participate in the 6G-XCEL research project
• Perform excellent scientific research
• Develop research prototypes and conduct experiments
• Integrate the proposed methods with or in Modelar DB
• Publish in leading international conferences and journals
• Participate in activities of the group and the department

Some teaching within the educations offered by the Department of Computer Science can be expected.
