About the position

We have a vacancy for one PhD Research Fellow position at the Department of Electronic Systems (IES). The PhD position is for up to 4 years with 25% work assignments for NTNU IES.

The position reports to head of department

Main duties and responsibilities

Sequential data is at the core of most real life application of machine learning and artificial intelligence. Speech recognition and synthesis, human activity recognition and robot navigation are some classical examples, but also monitoring of biometric signals and tracking of devices in mobile telecommunications and internet-of-things involve sequential data.

The machine learning methods used to solve these problems typically rely on large amounts of annotated data. This poses a number of problems:

  • the high cost of producing annotations limits the applicability of the methods to domains or user groups that do not justify the cost. For speech technology, for example, this is the case for languages spoken by fewer speakers, or by speaker groups that for geographical, physical or psychical condition diverge from the standard speakers.
  • the representations to use and target classes to be learned must be decided in advance by the researches in order to instruct the annotators.
  • life-long (open-ended) learning, after the system is deployed, is not possible because it would require human supervision at low signal level.

In addition, the methods that are currently most successful are not easily interpretable, which limits their flexibility and the fundamental knowledge that can be acquired by developing them.

The successful candidate will work at developing unsupervised machine learning methods for pattern discovery and detection in sequential data that are interpretable. The main application domain will be the speech signal, but other applications may be considered. The candidate may work in collaboration with the already established AULUS project.

Qualification requirements

We seek a highly-motivated individual who has

  • strong background in machine learning, signal processing and mathematics with research-oriented master thesis in a related field, e.g., statistical machine learning, statistical signal processing, speech technology, information theory, applied mathematics, or optimization
  • experience with programming
  • good written and oral English language skills

Publication activities in the aforementioned disciplines will be considered an advantage but is not a requirement.

For more information on the application submission and a detailed list of required documents, see subsection "About the application" below. The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in Computer Science, Electrical Engineering, Computer Science, Applied Mathematics, or other relevant disciplines with a grade A or B in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.

Personal characteristics

The successful candidate should

  • be creative, independent, and self-motivated
  • possess good skills to deliver oral and written presentations of research results

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement
