Time Series Compression using Quaternion Valued Neural Networks and Quaternion Backpropagation

no code implementations18 Mar 2024 Johannes Pöppelbaum, Andreas Schwung

This time-series is processed using quaternion valued neural network layers, where we aim to preserve the relation between these features through the usage of the Hamilton product.

Introducing PetriRL: An Innovative Framework for JSSP Resolution Integrating Petri nets and Event-based Reinforcement Learning

no code implementations23 Jan 2024 Sofiene Lassoued, Andreas Schwung

Ultimately, our approach not only demonstrates a robust ability to generalize across various instance sizes but also leverages the Petri net's graph nature to dynamically add job operations during the inference phase without the need for agent retraining, thereby enhancing flexibility.

Information Fusion for Assistance Systems in Production Assessment

no code implementations31 Aug 2023 Fernando Arévalo, Christian Alison M. Piolo, M. Tahasanul Ibrahim, Andreas Schwung

We propose a novel methodology to define assistance systems that rely on information fusion to combine different sources of information while providing an assessment.

Quaternion Backpropagation

no code implementations26 Dec 2022 Johannes Pöppelbaum, Andreas Schwung

Quaternion valued neural networks experienced rising popularity and interest from researchers in the last years, whereby the derivatives with respect to quaternions needed for optimization are calculated as the sum of the partial derivatives with respect to the real and imaginary parts.

Anomaly Detection using Ensemble Classification and Evidence Theory

no code implementations23 Dec 2022 Fernando Arévalo, Tahasanul Ibrahim, Christian Alison M. Piolo, Andreas Schwung

We present an architecture for multi-class ensemble classification and an approach to quantify the uncertainty of the individual classifiers and the ensemble classifier.

AWADA: Attention-Weighted Adversarial Domain Adaptation for Object Detection

no code implementations31 Aug 2022 Maximilian Menke, Thomas Wenzel, Andreas Schwung

Object detection networks have reached an impressive performance level, yet a lack of suitable data in specific applications often limits it in practice.

Predicting Rigid Body Dynamics using Dual Quaternion Recurrent Neural Networks with Quaternion Attention

no code implementations17 Nov 2020 Johannes Pöppelbaum, Andreas Schwung

We propose a novel neural network architecture based on dual quaternions which allow for a compact representation of informations with a main focus on describing rigid body movements.

Curiosity Based Reinforcement Learning on Robot Manufacturing Cell

no code implementations17 Nov 2020 Mohammed Sharafath Abdul Hameed, Md Muzahid Khan, Andreas Schwung

To this end, we apply a curiosity based reinforcement learning, using intrinsic motivation as a form of reward, on a flexible robot manufacturing cell to alleviate this problem.

Gradient Monitored Reinforcement Learning

no code implementations25 May 2020 Mohammed Sharafath Abdul Hameed, Gavneet Singh Chadha, Andreas Schwung, Steven X. Ding

The proposed method which we term as Gradient Monitoring(GM), is an approach to steer the learning in the weight parameters of a neural network based on the dynamic development and feedback from the training process itself.

Neural Logic Rule Layers

1 code implementation1 Jul 2019 Jan Niclas Reimann, Andreas Schwung

Compared to e. g. decision trees or bayesian classifiers, DNN suffer from bad interpretability where we understand by interpretability, that a human can easily derive the relations modeled by the network.

Learning the Non-linearity in Convolutional Neural Networks

no code implementations29 May 2019 Gavneet Singh Chadha, Andreas Schwung

The weights of this matrix then constitute the exponents of the corresponding components of the receptive field.

Generalized Dilation Neural Networks

no code implementations8 May 2019 Gavneet Singh Chadha, Jan Niclas Reimann, Andreas Schwung

One of the strengths of convolutional layers is the ability to learn features about spatial relations in the input domain using various parameterized convolutional kernels.
