Correlation Clustering of Organoid Images

no code implementations20 Mar 2024 Jannik Presberger, Rashmiparvathi Keshara, David Stein, Yung Hae Kim, Anne Grapin-Botton, Bjoern Andres

In biological and medical research, scientists now routinely acquire microscopy images of hundreds of morphologically heterogeneous organoids and are then faced with the task of finding patterns in the image collection, i. e., subsets of organoids that appear similar and potentially represent the same morphological class.

Correlation Clustering of Bird Sounds

no code implementations16 Jun 2023 David Stein, Bjoern Andres

We address the following questions: How accurate is this clustering, compared to a classification of the test set?

Partial Optimality in Cubic Correlation Clustering

no code implementations9 Feb 2023 David Stein, Silvia Di Gregorio, Bjoern Andres

The higher-order correlation clustering problem is an expressive model, and recently, local search heuristics have been proposed for several applications.

Structured Prediction Problem Archive

no code implementations4 Feb 2022 Paul Swoboda, Bjoern Andres, Andrea Hornakova, Florian Bernard, Jannik Irmai, Paul Roetzer, Bogdan Savchynskyy, David Stein, Ahmed Abbas

In order to facilitate algorithm development for their numerical solution, we collect in one place a large number of datasets in easy to read formats for a diverse set of problem classes.

Inapproximability of a Pair of Forms Defining a Partial Boolean Function

no code implementations9 Feb 2021 David Stein, Bjoern Andres

We consider the problem of jointly minimizing forms of two Boolean functions $f, g \colon \{0, 1\}^J \to \{0, 1\}$ such that $f + g \leq 1$ and so as to separate disjoint sets $A \cup B \subseteq \{0, 1\}^J$ such that $f(A) = \{1\}$ and $g(B) = \{1\}$.
