Stylometry Analysis of Multi-authored Documents for Authorship and Author Style Change Detection

no code implementations12 Jan 2024 Muhammad Tayyab Zamir, Muhammad Asif Ayub, Asma Gul, Nasir Ahmad, Kashif Ahmad

This paper investigates three key tasks of style analysis: (i) classification of single and multi-authored documents, (ii) single change detection, which involves identifying the point where the author switches, and (iii) multiple author-switching detection in multi-authored documents.

Effective Learning with Node Perturbation in Deep Neural Networks

no code implementations2 Oct 2023 Sander Dalm, Marcel van Gerven, Nasir Ahmad

Backpropagation (BP) is the dominant and most successful method for training parameters of deep neural network models.

Document Provenance and Authentication through Authorship Classification

no code implementations2 Mar 2023 Muhammad Tayyab Zamir, Muhammad Asif Ayub, Jebran Khan, Muhammad Jawad Ikram, Nasir Ahmad, Kashif Ahmad

In this paper, we propose an ensemble-based text-processing framework for the classification of single and multi-authored documents, which is one of the key tasks in style analysis.

Constrained Parameter Inference as a Principle for Learning

1 code implementation22 Mar 2022 Nasir Ahmad, Ellen Schrader, Marcel van Gerven

Backpropagation of error (BP) is an example of such an approach and has proven to be a highly successful application of stochastic gradient descent to deep neural networks.

Social Media as an Instant Source of Feedback on Water Quality

no code implementations9 Feb 2022 Khubaib Ahmad, Muhammad Asif Ayub, Kashif Ahmad, Jebran Khan, Nasir Ahmad, Ala Al-Fuqaha

Explainable Event Recognition

no code implementations2 Oct 2021 Imran Khan, Kashif Ahmad, Namra Gul, Talhat Khan, Nasir Ahmad, Ala Al-Fuqaha

The results of the study indicate that 78%, 84%, and 78% of the model decisions on natural disasters, sports, and social events datasets, respectively, are based onevent-related objects or regions.

Gradient-adjusted Incremental Target Propagation Provides Effective Credit Assignment in Deep Neural Networks

no code implementations23 Feb 2021 Sander Dalm, Nasir Ahmad, Luca Ambrogioni, Marcel van Gerven

Many of the recent advances in the field of artificial intelligence have been fueled by the highly successful backpropagation of error (BP) algorithm, which efficiently solves the credit assignment problem in artificial neural networks.

The extracted features are then used to train multiple individual classifiers whose scores are then combined in a late fusion manner achieving an F1-score of 0. 75%.

GAIT-prop: A biologically plausible learning rule derived from backpropagation of error

1 code implementation NeurIPS 2020 Nasir Ahmad, Marcel A. J. van Gerven, Luca Ambrogioni

An alternative called target propagation proposes to solve this implausibility by using a top-down model of neural activity to convert an error at the output of a neural network into layer-wise and plausible 'targets' for every unit.

Overcoming the Weight Transport Problem via Spike-Timing-Dependent Weight Inference

1 code implementation9 Mar 2020 Nasir Ahmad, Luca Ambrogioni, Marcel A. J. van Gerven

We propose a solution to the weight transport problem, which questions the biological plausibility of the backpropagation algorithm.
