In our group, we develop machine learning approaches for building approximate Bayesian posteriors using only a small number of likelihood evaluations, which can be a game-changer for complex models or when resources are limited. Think of Bayesian optimization, a very effective technique to optimize black-box functions, but scaled up to perform full Bayesian inference. This project will build on the state-of-the-art framework developed in our group,
Example research directions for this project include extending the scalability of VBMC to more complex posteriors and higher dimension (see for example
The project will include research visits abroad to work with collaborators, such as
The position is full-time, funded for four years (PhD) or 2+2 years (postdoc) and will be filled as soon as possible, with a target starting date in September 2023 (later dates can be negotiated). This project is funded by the Research Council of Finland.
The work involves research-related activities, including conducting theoretical and applied research, designing and programming machine learning software, computational and data analyses, writing research articles, participating in and presenting research at academic conferences, taking part in international research visits, and teaching-related activities.
The ideal candidate has a strong background in computational statistics and/or machine learning, and experience with Bayesian methods (e.g., MCMC, variational inference, probabilistic programming, simulator-based inference). The following constitute an advantage, but are not required:
Excellent written and oral communication skills in English are needed.
Applicants should have – or be about to obtain – a MSc (for the PhD position) or a PhD (for the postdoctoral position) in machine learning, computer science, data science, applied mathematics and statistics, physics, computational neuroscience, or a related field.
Applicants for the PhD position who do not currently hold a doctoral student status in the Doctoral Programme in Computer Science at the University of Helsinki are eligible to apply, but in the event of hiring, they are expected to acquire the status during the standard 6-month probationary period.
The position is full-time and funded for four years (PhD position) or 2+2 years (postdoc). The starting salary is 2400–2800 euros/month (for a doctoral student) and 3600–4200 euros/month (for a postdoc), depending on previous qualifications and experience.
The University of Helsinki offers comprehensive services to its employees, including occupational health care and health insurance, sports facilities, and opportunities for professional development. The
