Matrix Factorization for Collaborative Filtering Is Just Solving an Adjoint Latent Dirichlet Allocation Model After All

1 code implementation ACM Conference on Recommender Systems 2021 Florian Wilhelm

In this work, we provide a theoretical link between unconstrained and the interpretable non-negative matrix factorization in terms of the personalized ranking induced by these methods.

Windowing Models for Abstractive Summarization of Long Texts

no code implementations7 Apr 2020 Leon Schüller, Florian Wilhelm, Nico Kreiling, Goran Glavaš

Neural summarization models suffer from the fixed-size input limitation: if text length surpasses the model's maximal number of input tokens, some document content (possibly summary-relevant) gets truncated Independently summarizing windows of maximal input size disallows for information flow between windows and leads to incoherent summaries.

On the Effectiveness of Low-rank Approximations for Collaborative Filtering compared to Neural Networks

1 code implementation30 May 2019 Marcel Kurovski, Florian Wilhelm

Even in times of deep learning, low-rank approximations by factorizing a matrix into user and item latent factors continue to be a method of choice for collaborative filtering tasks due to their great performance.
