Detta jobb är inaktivt och går inte att söka längre.

About the job

Scania is one of the world’s leading manufacturer of trucks and buses for heavy transports, as well as industrial and marine engines. Transport services and logistics services make up an increasing part of our business, which guarantees Scania’s customers cost-efficient transport solutions and high availability. Over a million Scania vehicles are in active use, in over 100 countries.

In the Connectivity section within Scania R&D, we develop new solutions for connected vehicles in our Internet of Things (IoT) platform, as part of Scania’s increasing focus on communication, services and smart transport solutions. Advanced data analysis capabilities are a cornerstone enabler in this development.

Target/scope

The goal of this project is to use deep learning methods to generate sequential geospatial traces that are similar to real trips driven by our vehicles. Generating synthetic data has in recent years become a very popular way to increase data repository, but also a way to use non-private data for model development or testing functionalities due to GDPR. In particular in the field of GANs (generative adversarial networks) generating realistic face photos of non-existing persons. Now, geospatial data together with time and date are sensitive since it could be back-tracked to an individual and thus is very personal. Thus being able to generate realistic geospatial data together with some vehicle data would be invaluable for Scania. A big challenge with geospatial data is that the position has a physical context, meaning that generating a geoposition in the middle of an ocean is not desirable unless there is a ferry route.

Training data is available in the form of several years of geospatial traces from Scania’s global connected fleet of more than 450 000 heavy trucks and buses. The student will have access to Scania’s Hadoop cluster as computational resources to train and run their models.

Description of the assignment

  1. Evaluate suitable metrics to compare generated data against real data.
  2. Identify and evaluate suitable methods for generating fake geospatial traces with other vehicle data.
  3. Visually compare generated data with real data on a map.

If time permits,

  • Extend to generate more different types of vehicle data, such as fault codes.
