DISCO: Internal Evaluation of Density-Based Clustering

no code implementations28 Feb 2025 Anna Beer, Lena Krieger, Pascal Weber, Martin Ritzert, Ira Assent, Claudia Plant

In this paper, we propose DISCO, a Density-based Internal Score for Clustering Outcomes, which is the first CVI that also evaluates the quality of noise labels.

I Want 'Em All (At Once) -- Ultrametric Cluster Hierarchies

no code implementations19 Feb 2025 Andrew Draganov, Pascal Weber, Rasmus Skibdahl Melanchton Jørgensen, Anna Beer, Claudia Plant, Ira Assent

Hierarchical clustering is a powerful tool for exploratory data analysis, organizing data into a tree of clusterings from which a partition can be chosen.

SHADE: Deep Density-based Clustering

1 code implementation8 Oct 2024 Anna Beer, Pascal Weber, Lukas Miklautz, Collin Leiber, Walid Durani, Christian Böhm, Claudia Plant

Similar to existing deep clustering algorithms, SHADE supports high-dimensional and large data sets with the expressive power of a deep autoencoder.

Deep Clustering With Consensus Representations

no code implementations13 Oct 2022 Lukas Miklautz, Martin Teuffenbach, Pascal Weber, Rona Perjuci, Walid Durani, Christian Böhm, Claudia Plant

Further, we propose DECCS (Deep Embedded Clustering with Consensus representationS), a deep consensus clustering method that learns a consensus representation by enhancing the embedded space to such a degree that all ensemble members agree on a common clustering result.

Remember and Forget Experience Replay for Multi-Agent Reinforcement Learning

no code implementations24 Mar 2022 Pascal Weber, Daniel Wälchli, Mustafa Zeqiri, Petros Koumoutsakos

We present the extension of the Remember and Forget for Experience Replay (ReF-ER) algorithm to Multi-Agent Reinforcement Learning (MARL).

Learning swimming escape patterns for larval fish under energy constraints

no code implementations3 May 2021 Ioannis Mandralis, Pascal Weber, Guido Novati, Petros Koumoutsakos

The present, data efficient, reinforcement learning algorithm results in an array of patterns that reveal practical flow optimization principles for efficient swimming and the methodology can be transferred to the control of aquatic robotic devices operating under energy constraints.
