PlasmoFAB: A Benchmark to Foster Machine Learning for Plasmodium falciparum Protein Antigen Candidate Prediction

1 code implementation16 Jan 2023 Jonas Christian Ditz, Jacqueline Wistuba-Hamprecht, Timo Maier, Rolf Fendel, Nico Pfeifer, Bernhard Reuter

Results: We developed PlasmoFAB, a curated benchmark that can be used to train machine learning methods for the exploration of Plasmodium falciparum protein antigen candidates.

COmic: Convolutional Kernel Networks for Interpretable End-to-End Learning on (Multi-)Omics Data

1 code implementation2 Dec 2022 Jonas C. Ditz, Bernhard Reuter, Nico Pfeifer

By combining convolutional kernel networks with pathway-induced kernels, our method enables robust and interpretable end-to-end learning on omics datasets ranging in size from a few hundred to several hundreds of thousands of samples.

CECILIA: Comprehensive Secure Machine Learning Framework

no code implementations7 Feb 2022 Ali Burak Ünal, Nico Pfeifer, Mete Akgün

To address this, we propose a secure 3-party computation framework, CECILIA, offering PP building blocks to enable complex operations privately.

Convolutional Motif Kernel Networks

1 code implementation3 Nov 2021 Jonas C. Ditz, Bernhard Reuter, Nico Pfeifer

Our proposed method can be utilized on DNA and protein sequences.

ppAURORA: Privacy Preserving Area Under Receiver Operating Characteristic and Precision-Recall Curves

no code implementations17 Feb 2021 Ali Burak Ünal, Nico Pfeifer, Mete Akgün

In this setting, it can also be a problem to compute the global AUC, since the labels might also contain privacy-sensitive information.

ESCAPED: Efficient Secure and Private Dot Product Framework for Kernel-based Machine Learning Algorithms with Applications in Healthcare

no code implementations4 Dec 2020 Ali Burak Ünal, Mete Akgün, Nico Pfeifer

We address this problem by introducing ESCAPED, which stands for Efficient SeCure And PrivatE Dot product framework, enabling the computation of the dot product of vectors from multiple sources on a third-party, which later trains kernel-based machine learning algorithms, while neither sacrificing privacy nor adding noise.

An interpretable multiple kernel learning approach for the discovery of integrative cancer subtypes

no code implementations20 Nov 2018 Nora K. Speicher, Nico Pfeifer

Due to the complexity of cancer, clustering algorithms have been used to disentangle the observed heterogeneity and identify cancer subtypes that can be treated specifically.

Partially blind domain adaptation for age prediction from DNA methylation data

no code implementations20 Dec 2016 Lisa Handl, Adrin Jalali, Michael Scherer, Nico Pfeifer

We apply the model to the problem of age prediction based on DNA methylation data from a variety of tissues, and compare it to a standard model, which does not take heterogeneity into account.
