Probabilistically Rewired Message-Passing Neural Networks

1 code implementation3 Oct 2023 Chendi Qian, Andrei Manolache, Kareem Ahmed, Zhe Zeng, Guy Van Den Broeck, Mathias Niepert, Christopher Morris

Message-passing graph neural networks (MPNNs) emerged as powerful tools for processing graph-structured input.

Semantic Strengthening of Neuro-Symbolic Learning

no code implementations28 Feb 2023 Kareem Ahmed, Kai-Wei Chang, Guy Van Den Broeck

Numerous neuro-symbolic approaches have recently been proposed typically with the goal of adding symbolic knowledge to the output layer of a neural network.

SIMPLE: A Gradient Estimator for $k$-Subset Sampling

1 code implementation4 Oct 2022 Kareem Ahmed, Zhe Zeng, Mathias Niepert, Guy Van Den Broeck

$k$-subset sampling is ubiquitous in machine learning, enabling regularization and interpretability through sparsity.

Semantic Probabilistic Layers for Neuro-Symbolic Learning

1 code implementation1 Jun 2022 Kareem Ahmed, Stefano Teso, Kai-Wei Chang, Guy Van Den Broeck, Antonio Vergari

We design a predictive layer for structured-output prediction (SOP) that can be plugged into any neural network guaranteeing its predictions are consistent with a set of predefined symbolic constraints.

Hierarchical Multi-label Classification Logical Reasoning

Performance Evaluation of Infrared Image Enhancement Techniques

no code implementations7 Feb 2022 Rania Gaber, AbdElmgied Ali, Kareem Ahmed

There are several types of IR radiation based on the range of wavelength and corresponding frequency.

Neuro-Symbolic Entropy Regularization

no code implementations25 Jan 2022 Kareem Ahmed, Eric Wang, Kai-Wei Chang, Guy Van Den Broeck

We propose a loss, neuro-symbolic entropy regularization, that encourages the model to confidently predict a valid object.

Content-Based Image Retrieval Using Multiresolution Analysis Of Shape-Based Classified Images

no code implementations8 Oct 2016 I. M. El-Henawy, Kareem Ahmed

The second feature vector describes the texture using eigenvalues of the 39 sub-bands that are generated after applying four levels 2D DWT in each channel (red, green and blue channels) of the image.
