Women in the Digital Industry: The Long Road of Drishti Maharjan

It was a very emotional moment for her. After all, it was not only geographically a long way from Nepal to the stage in Dresden Drishti Maharjan stood on. In her school, she had often been the only girl to attend inclination courses in natural sciences. And now she accepted the prize for the 3rd place in the Zeiss Women Award 2021. A competition that honors outstanding female students in subjects such as computer science or computer engineering.

Multi-fidelity machine learning

Imagine that we are not just given training samples (i.e. inputs and outputs) but specifically each of the samples is associated to a “cost” and might have a given “accuracy”.

This project investigates, how to find optimal machine learning models that do not only have a minimum loss / maximum accuracy but also a minimal overall cost. That is, we face a much more complex optimization task.

In the project, we touch topics in:

  • various regression ML methods
  • optimization
  • approximation theory

WARNING: Again a rather mathematical, but very beautiful topic. Could go from a very applied view to a pretty theoretical one.

This is highly research relevant and has very important applications in machine learning in simulation and other fields.

Machine Learning in Quantum Chemistry

In this research project, we are interested in the prediction of properties for molecules.

The project touches the following fields:

  • prediction of properties of molecules by quantum chemistry simulation software
  • optimal feature representation for molecules in machine learning
  • various types of machine learning techniques

This has tremendously important applications in the field of virtual material design, drug discovery, …

The actual work can range from utilizing and comparing existing machine learning methods in that field to developing completely new approaches.

Here some links:

Machine Learning in Fluid Mechanics

Computational Fluid Mechanics is a field in engineering, in which the computer is used to solve mathematical equations that describe the behavior of fluids like air or water. The just mentioned solution process is typically called “simulation”. The objective of this research topic is to investigate the application of Machine Learning models in fluid simulations. That is, the typically expensive simulation process is replaced by a Machine Learning problem.

This research project touches the following topics:

  • Modeling of fluids by the Navier-Stokes equations
  • use of an existing Navier Stokes fluid solver to generate training snapshots
  • further development of machine learning techniques for prediction of outcomes of fluid simulations
  • time-series prediction / quantity of interest prediction / spatial prediction

This is another hot topic, at least in the “simulation business”. Research-relevant questions are:

  • Can we find ML models that nicely predict bifurcation-like behavior?
  • Can we use ML models as sub-models (homogenization-like) in bigger models?

Here some links:

Wavelets as Features for Time Series ML

In this project, the idea would be to familiarize oneself further with the following concepts

  • time series data
  • Wavelet analysis to generate features
  • several types of machine learning models
    • kernel ridge regression
    • multilayer perceptron
    • radial basis function networks
    • transfer learning using some well-known image classifier

Application data can range from Quantum Chemistry over Finance to Health, hence is very broad.
The main objective would be to start with a “black box” approach, i.e. using some existing implementation of a continuous wavelet filter bank and then to develop a deeper understanding on how the choice of some parameters in the wavelet filter bank influences the prediction quality.

A first reference:

Radial Basis Function networks

This topic combines prior knowledge on kernel ridge regression with neural networks. The following content will be considered:

  • (deep) neural networks
  • kernel ridge regression
  • radial basis function networks

The objective would be to study the relationship of the predictive power of kernel ridge regression and radial basis function networks based on given data from quantum chemistry or other relevant science application.
