Atom-Level Optical Chemical Structure Recognition with Limited Supervision

1 code implementation2 Apr 2024 Martijn Oldenhof, Edward De Brouwer, Adam Arany, Yves Moreau

Identifying the chemical structure from a graphical representation, or image, of a molecule is a challenging pattern recognition task that would greatly benefit drug development.

Weakly Supervised Knowledge Transfer with Probabilistic Logical Reasoning for Object Detection

1 code implementation9 Mar 2023 Martijn Oldenhof, Adam Arany, Yves Moreau, Edward De Brouwer

In this work, we propose ProbKT, a framework based on probabilistic logical reasoning that allows to train object detection models with arbitrary types of weak supervision.

Collaborative Drug Discovery: Inference-level Data Protection Perspective

no code implementations13 May 2022 Balazs Pejo, Mina Remeli, Adam Arany, Mathieu Galtier, Gergely Acs

Pharmaceutical industry can better leverage its data assets to virtualize drug discovery through a collaborative machine learning platform.

Self-Labeling of Fully Mediating Representations by Graph Alignment

1 code implementation25 Mar 2021 Martijn Oldenhof, Adam Arany, Yves Moreau, Jaak Simm

In this paper we investigate the scenario of domain adaptation from the source domain where we have access to the expensive labels $V$ to the target domain where only normal labels W are available.

Latent Convergent Cross Mapping

no code implementations ICLR 2021 Edward De Brouwer, Adam Arany, Jaak Simm, Yves Moreau

Discovering causal structures of temporal processes is a major tool of scientific inquiry because it helps us better understand and explain the mechanisms driving a phenomenon of interest, thereby facilitating analysis, reasoning, and synthesis for such systems.

Multilevel Gibbs Sampling for Bayesian Regression

no code implementations25 Sep 2020 Joris Tavernier, Jaak Simm, Adam Arany, Karl Meerbergen, Yves Moreau

Additionally, the use of correlated samples is investigated for variance reduction to improve the convergence of the Markov Chain.

ChemGrapher: Optical Graph Recognition of Chemical Compounds by Deep Learning

1 code implementation23 Feb 2020 Martijn Oldenhof, Adam Arany, Yves Moreau, Jaak Simm

Many thousands of scientific articles in chemistry and pharmaceutical sciences have investigated chemical compounds, but in cases the details of the structure of these chemical compounds is published only as an images.

Expressive Graph Informer Networks

1 code implementation25 Jul 2019 Jaak Simm, Adam Arany, Edward De Brouwer, Yves Moreau

Applying machine learning to molecules is challenging because of their natural representation as graphs rather than vectors. Several architectures have been recently proposed for deep learning from molecular graphs, but they suffer from informationbottlenecks because they only pass information from a graph node to its direct neighbors.

GRU-ODE-Bayes: Continuous modeling of sporadically-observed time series

4 code implementations NeurIPS 2019 Edward De Brouwer, Jaak Simm, Adam Arany, Yves Moreau

Modeling real-world multidimensional time series can be particularly challenging when these are sporadically observed (i. e., sampling is irregular both in time and across dimensions)-such as in the case of clinical patient data.

Highly Scalable Tensor Factorization for Prediction of Drug-Protein Interaction Type

no code implementations1 Dec 2015 Adam Arany, Jaak Simm, Pooya Zakeri, Tom Haber, Jörg K. Wegner, Vladimir Chupakhin, Hugo Ceulemans, Yves Moreau

Method: to analyze the interaction types we propose factorization method Macau which allows us to combine different measurement types into a single tensor together with proteins and compounds.
