Descripción de la oferta de trabajo:

Applications are invited for a 3-year PhD position funded by the European Commission's Marie Sk?odowska-Curie Innovative Training Networks: 'MENTOR -Machine LEarning in Optical NeTwORks'. The objective of the MENTOR project is to develop novel machine learning based strategies for communication over the nonlinear optical fiber channel. The start date is flexible, but preferably before August 1, 2020. The project is interdisciplinary and will cover topics within the field of machine learning and optical communication. The project will be carried out in Machine Learning in Photonic Systems (M-LiPS), group. The group has a strong track record and and industry collaboration in the application of machine learning techniques to optical communication systems and photonic systems in general.

This Ph.D. project will explore the latest advances within machine learning to enable nonlinear-distortion free communication over the optical fibre channel. It will be explored how to explore machine learning techniques to enable spectrally efficient and robust optical communication systems covering ultra-wide band transmission (O+E+S+C+L band). More specifically, the application and efficient training for auto-encoders will be investigated. The project will cover both algorithm development as well as experimental implementations.

Responsibilities and qualifications

This PhD position will investigate the research topics below using both theoretical and experimental methods, but not limited to these topics:

  • Develop novel machine learning based transmitter and receiver schemes
  • Develop novel training algorithms for deep neural networks
  • Investigate the impact of non-ideal transmission schemes on the performance of the algorithms
  • Test the developed algorithms in an experimental test-bed

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

You are expected to have experience with development of machine learning algorithms and coherent optical communication systems.

Moreover you shall have additional skills as:

  • Good understanding of digital communications
  • Good theoretical understanding of nonlinear optics
  • Experience with machine learning techniques (expectation maximization algorithms, neural networks, Guassian processes, etc.)
  • Experience using Python, MATLAB or similar
  • Experience with software for version control such as git
  • Ability to work independently, to plan and carry out complicated tasks
  • Good communication skills in English, both written and spoken
  • Innovative skills and the ability to generate new ideas

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide. http://www.dtu.dk/english/Education/PhD/Rules/PhDguide

Assessment

The assessment of the applicants will be made by Professor Darko Zibar.
