Optimisation Principles, Models and Algorithms for Dictionary Learning

Hello creative brains!

No open jobs for now but we will probably start hiring again once we know whether we have money until '21 and how much (mid'18).

In the meantime enjoy browsing and if this gets you mega-super-motivated for dictionary learning don't hesitate to contact us. We can probably still arrange a research visit.

If have you most of the skills in linear algebra, probability theory and/or functional analysis and all the interest in dictionary learning but don't have a master's project yet, come for a chat (msc)!

Finally, if your head is still spinning from the introductory lectures but you think that messing around with images could be fun, check out our bachelor projects (bsc)!

In between holidays, group is driven mad by Karin trying to find the correct cut-off for adaptive dictionary learning, ie. how to distinguish between atoms and rubbish in the case of noisy data. Fortunately after the engineering/cooking approach failed, going back to theory worked, e.g. we have a criterion and sanity is preserved!! We are also implementing the better step size for analysis operator learning and writing up the big paper on compressed dictionary learning - slowly (compare July entry).

Family trip to FoCM in Barcelona!! While Flavio, Michi and Marie were sweating, Karin's brain finally reached operating temperature. List of achievements: pretty talk on adaptive dictionary learning, magic new step size for analysis operator learning, squeezing promise for help with random subdictionaries out of Joel (Tropp), realising yet again that in most talks we know as much as Jon Snow. Also cervical supercooling is now the official reason for slow publishing.

We (Karin, Flavio and Michi) went to SPARS in Lisbon to entertain people with compressed dictionary learning and analysis operator learning, more details here. On this occasion we also witnessed for the first time in our lives left-over-cake at a conference, amazing!!!


[May17]
Tinkering with theory for nightmare paper went well, so Karin is back to tweaking millions of screws to make it work in practice. Flavio is off to Rennes learning audio dictionaries. Michi is praying for paper acceptance and dreaming of the end of his PhD, while Marie is thoroughly enjoying the misery and self-doubt of her first PhD year.


[Apr17]
Michi hit the arXiv submit button! If you can't bear to leave this page to go to arXiv, the analysis operator learning nightmare paper is also available here and we even have a toolbox to play around with!


[Mar17]
We hosted the WDI2 workshop, nobody complained so I'd say success! More good news, both our SPARS abstracts were accepted so we (Flavio, Michi, Karin) are going to Lisbon. Eventful month, congratulations to Marie for successfully defending her MSc thesis and officially starting the PhD!! Useful side effect, Michi the older kid got jealous and started to actually write the paper, let's see when we finish.


[Feb17]
February - Karin tinkering with theory for her nightmare paper, Flavio exploding the cluster with simulations, Michi on holidays in Cuba and Marie putting the finishing touches on her MSc thesis - nothing much happening - well it is a short month.


[Jan17]
Hello World!!!
To celebrate the acceptance of the first cofunded paper [pdf], the submission of the first fully funded paper [pdf], the quasi - completeness of the team and the organisation of our first workshop [wdi2].... voila a website!!!
