A Knowledge Representation Approach to Automated Mathematical Modelling

no code implementations12 Nov 2020 Bahadorreza Ofoghi, Vicky Mak, John Yearwood

In the search for a suitable machine-readable knowledge representation structure for MILPs, we propose an optimization modelling tree built based upon an MILP model ontology that can be used as a guide for automated systems to elicit an MILP model from end-users on their combinatorial business optimization problems.

Choosing a sampling frequency for ECG QRS detection using convolutional networks

no code implementations4 Jul 2020 Ahsan Habib, Chandan Karmakar, John Yearwood

Automated QRS detection methods depend on the ECG data which is sampled at a certain frequency, irrespective of filter-based traditional methods or convolutional network (CNN) based deep learning methods.

ECG QRS Detection

Impact of ECG Dataset Diversity on Generalization of CNN Model for Detecting QRS Complex

no code implementations IEEE Access 2019 Ahsan Habib, Chandan Karmakar, John Yearwood

In real life, a promising QRS detector may be expected to achieve acceptable accuracy over diverse ECG recordings and, thus, investigation of the model's generalization capability is crucial.
