This site aims to give an overview of my scientific work, interests, and current and past research outputs. I am Jesper Løve Hinrich, currently a Postdoctoral researcher at the DTU Compute in the Section for Cognitive Systems and affiliated with the UCPH chemometrics group and the Pioneer Centre for AI .

I have a background in mathematics, statistics and computer science. My research interests are machine learning, intelligence and life science applications.

The main part of my research is focused on multi-way methods for decomposition and deconvolution of measurements in physical, chemical, and biological systems. This work is centered around probabilistic (Bayesian) modeling, inclusion of domain expertise, and providing interpretable models.


The core of my research is Mathematics and Statistical Science, in particular probabilistic machine learning. My work focuses on developing statistical methods for generating robust insights through Bayesian/probabilistic modelling, the incorporation of prior knowledge, and uncertainty quantification in relation to the data input and latent parameters.

I have a strong interesting in tensor modelling, with tensors being generalizations of vectors (1st order tensors) and matrices (2nd order tensor) to N-dimensional arrays (N'th order tensors), also known as multi-way or N-way arrays. A 3rd order tensor can thus be thought of as a data cube where each dimension of this cube corresponds to a mode of the tensor. Whereas conventional 2-way matrices are well understood the geometry and properties of higher order arrays are still far from fully understood. Tensors are common in modern life science data, such as;

  • 1) Neuroimaging with data typically measured from different parts of the brain (e.g. voxels) over time for a number of trials or persons, providing a three way tensor for instance with modes voxels x time x persons.

  • 2) Chemometrics in which for instance fluorescence spectroscopy gives rise to data of emission and excitation spectra across multiple samples, i.e. forming a 3-way array of emission spectra x excitation spectra x samples.

  • 3) Genetics research where for instance gene expression data records which genes are expressed in a number of persons, as well as different parts of their body (tissue). Giving a person x gene x tissue tensor.

Several tensor analysis toolboxes are now publicly available. The most prominent ones being the n-way toolbox, Tensor Toolbox, Tensorlab and Tensorly . While extremely successful, these toolboxes do not allow for probabilistic (fully Bayesian) modeling and are based solely on maximum likelihood estimation. To mitigate this, the development of the Probabilistic Tensor Toolbox was initiated as part of my PhD and is in continuous - but intermittent - development.

A probabilistic approach allows for handling parameter uncertainty in a natural way and enables incorporation of more realistic noise model assumptions such as mode heteroscedastic, auto-regressive or Markovian noise.
