Postdoc in Machine Learning using Tensor Networks - DTU Compute

This PostDoc project will push the boundaries of scalability, reliability, and explainability of tensor networks (TN) and develop a novel computationally efficient and expressive TN data science tool providing a strong complimentary generic framework to deep learning
Are you interested in developing novel machine learning methodologies that are scalable, reliable and explainable and that can address imminent challenges both within quantum physics and the life-sciences?

As our new colleague your job will be to develop novel computational frameworks for machine learning by use of tensor network representations. In particular, you will push the boundaries of

• Scalability, drawing upon recent large-scale TN capabilities in physics.
• Reliability, exploring uncertainty quantification and robust inference in machine learning
• Explainability, leveraging identifiability and unique recovery explored using tensor decompositions within the life-science domain.

A Tensor Network (TN) is a data structure for representing high-dimensional arrays (tensors) in a low-rank format as a sequence of smaller cores which can be stored and manipulated efficiently. TNs provide promising tools for large-scale machine learning, as they allow for exponential savings in memory and processing time, while often allowing for explainable structure extraction. However, key obstacles remain, preventing their widespread use. These include limitations in terms of reliable large-scale inference, uncertainty quantification, as well as efficient TN structure identification, assessment, and interpretation. You will address these obstacles and demonstrate how the developed tools can address important challenges within quantum physics as well as large-scale life-science data modeling.

Responsibilities and qualifications
You are fascinated by machine learning and how computers can learn from data and you have a strong interest in the mathematical foundation of machine learning models. In this position, you will be responsible for developing novel tensor network based machine learning methodologies enabling new approaches for solving supervised, unsupervised and reinforcement learning problems. You will thereby leverage tensor networks as a computationally efficient and expressive framework that provides a complimentary generic framework to deep learning.

Specifically, we are looking for a profile with the motivation and drive needed for making a difference that matters. You must bring an open mindset and like to create results via collaboration with multiple people with different professional and cultural backgrounds. You are a talented, self-motivated, and team-oriented person who enjoys working on the theoretical foundation of machine learning. In particular, your CV comprises:

• A strong relevant background within machine learning and mathematics.
• Extensive experience programming in Python (or Matlab).
• An active interest or experience in strong collaborations and interdisciplinary work at the intersection between machine learning, physics and life-science data modeling.
• You must be fluent in English, both speaking and writing and possess excellent communication skills.

You will be supervised by Professor Morten Mørup at DTU Compute, Section for Cognitive Systems and also closely collaborate with Prof. Rasmus Bro and Assoc. Prof. Michael Kastoryano at the University of Copenhagen Department of Food Science and Department of Computer Science respectively. The position is financed by the Novo Nordisk Foundation Data Science Collaborative Grant “Tensor Networks for Data Science”.

As a formal qualification, you must hold a PhD degree (or equivalent).
