Shrub Ensembles for Online Classification

no code implementations7 Dec 2021 Sebastian Buschjäger, Sibylle Hess, Katharina Morik

Among the most successful online learning methods are Decision Tree (DT) ensembles.

There is no Double-Descent in Random Forests

1 code implementation8 Nov 2021 Sebastian Buschjäger, Katharina Morik

Last, we study the diversity of an ensemble as a tool the estimate its performance.

Improving the Accuracy-Memory Trade-Off of Random Forests Via Leaf-Refinement

1 code implementation19 Oct 2021 Sebastian Buschjäger, Katharina Morik

In this paper, we revisit ensemble pruning in the context of `modernly' trained Random Forests where trees are very large.

Ensemble Pruning

Providing Meaningful Data Summarizations Using Exemplar-based Clustering in Industry 4.0

no code implementations25 May 2021 Philipp-Jan Honysz, Alexander Schulze-Struchtrup, Sebastian Buschjäger, Katharina Morik

Data summarizations are a valuable tool to derive knowledge from large data streams and have proven their usefulness in a great number of applications.

Bit Error Tolerance Metrics for Binarized Neural Networks

no code implementations2 Feb 2021 Sebastian Buschjäger, Jian-Jia Chen, Kuan-Hsun Chen, Mario Günzel, Katharina Morik, Rodion Novkin, Lukas Pfahler, Mikail Yayla

In this study, our objective is to investigate the internal changes in the NNs that bit flip training causes, with a focus on binarized NNs (BNNs).

Generalized Negative Correlation Learning for Deep Ensembling

2 code implementations5 Nov 2020 Sebastian Buschjäger, Lukas Pfahler, Katharina Morik

Ensemble algorithms offer state of the art performance in many machine learning applications.

Towards Explainable Bit Error Tolerance of Resistive RAM-Based Binarized Neural Networks

no code implementations3 Feb 2020 Sebastian Buschjäger, Jian-Jia Chen, Kuan-Hsun Chen, Mario Günzel, Christian Hakert, Katharina Morik, Rodion Novkin, Lukas Pfahler, Mikail Yayla

Finally, we explore the influence of a novel regularizer that optimizes with respect to this metric, with the aim of providing a configurable trade-off in accuracy and BET.
