Estimating Text Similarity based on Semantic Concept Embeddings

no code implementations9 Jan 2024 Tim vor der Brück, Marc Pouly

Due to their ease of use and high accuracy, Word2Vec (W2V) word embeddings enjoy great success in the semantic representation of words, sentences, and whole documents as well as for semantic similarity estimation.

Towards Reliable Dermatology Evaluation Benchmarks

1 code implementation13 Sep 2023 Fabian Gröger, Simone Lionetti, Philippe Gottfrois, Alvaro Gonzalez-Jimenez, Matthew Groh, Roxana Daneshjou, Labelling Consortium, Alexander A. Navarini, Marc Pouly

Benchmark datasets for digital dermatology unwittingly contain inaccuracies that reduce trust in model performance estimates.

Robust T-Loss for Medical Image Segmentation

1 code implementation1 Jun 2023 Alvaro Gonzalez-Jimenez, Simone Lionetti, Philippe Gottfrois, Fabian Gröger, Marc Pouly, Alexander Navarini

Our results provide strong evidence that the T-Loss is a promising alternative for medical image segmentation where high levels of noise or outliers in the dataset are a typical phenomenon in practice.

Cable Tree Wiring -- Benchmarking Solvers on a Real-World Scheduling Problem with a Variety of Precedence Constraints

1 code implementation25 Nov 2020 Jana Koehler, Joseph Bürgler, Urs Fontana, Etienne Fux, Florian Herzog, Marc Pouly, Sophia Saller, Anastasia Salyaeva, Peter Scheiblechner, Kai Waelti

We summarize our investigations to model this cable tree wiring Problem (CTW) as a traveling salesman problem with atomic, soft atomic, and disjunctive precedence constraints as well as tour-dependent edge costs such that it can be solved by state-of-the-art constraint programming (CP), Optimization Modulo Theories (OMT), and mixed-integer programming (MIP) solvers.

Text Similarity Estimation Based on Word Embeddings and Matrix Norms for Targeted Marketing

no code implementations NAACL 2019 Tim vor der Br{\"u}ck, Marc Pouly

The prevalent way to estimate the similarity of two documents based on word embeddings is to apply the cosine similarity measure to the two centroids obtained from the embedding vectors associated with the words in each document.

Sufficient and necessary conditions for Dynamic Programming in Valuation-Based Systems

no code implementations14 Aug 2015 Jordi Roca-Lacostena, JesUs Cerquides, Marc Pouly

In spite of that, the mainline of Pouly and Kohlas' theory is correct, although some of the necessary conditions have to be revised.
