OPTWIN: Drift identification with optimal sub-windows

no code implementations19 May 2023 Mauro Dalle Lucca Tosi, Martin Theobald

One of the main challenges of OL is the inherent presence of concept drifts, which are commonly defined as unforeseeable changes in the statistical properties of an incoming data stream over time.

Enriching Relation Extraction with OpenIE

no code implementations19 Dec 2022 Alessandro Temperoni, Maria Biryukov, Martin Theobald

Relation extraction (RE) is a sub-discipline of information extraction (IE) which focuses on the prediction of a relational predicate from a natural-language input unit (such as a sentence, a clause, or even a short paragraph consisting of multiple sentences and/or clauses).

Robust and Provable Guarantees for Sparse Random Embeddings

no code implementations22 Feb 2022 Maciej Skorski, Alessandro Temperoni, Martin Theobald

In this work, we improve upon the guarantees for sparse random embeddings, as they were recently provided and analyzed by Freksen at al. (NIPS'18) and Jagadeesan (NIPS'19).

Revisiting Initialization of Neural Networks

no code implementations20 Apr 2020 Maciej Skorski, Alessandro Temperoni, Martin Theobald

The proper initialization of weights is crucial for the effective training and fast convergence of deep neural networks (DNNs).
