An Aggregation of Aggregation Methods in Computational Pathology

no code implementations2 Nov 2022 Mohsin Bilal, Robert Jewsbury, Ruoyu Wang, Hammam M. AlGhamdi, Amina Asif, Mark Eastwood, Nasir Rajpoot

Image analysis and machine learning algorithms operating on multi-gigapixel whole-slide images (WSIs) often process a large number of tiles (sub-images) and require aggregating predictions from the tiles in order to predict WSI-level labels.

REET: Robustness Evaluation and Enhancement Toolbox for Computational Pathology

1 code implementation28 Jan 2022 Alex Foote, Amina Asif, Nasir Rajpoot, Fayyaz Minhas

Motivation: Digitization of pathology laboratories through digital slide scanners and advances in deep learning approaches for objective histological assessment have resulted in rapid progress in the field of computational pathology (CPath) with wide-ranging applications in medical and pharmaceutical research as well as clinical workflows.

Towards Launching AI Algorithms for Cellular Pathology into Clinical & Pharmaceutical Orbits

no code implementations17 Dec 2021 Amina Asif, Kashif Rajpoot, David Snead, Fayyaz Minhas, Nasir Rajpoot

Computational Pathology (CPath) is an emerging field concerned with the study of tissue pathology via computational algorithms for the processing and analysis of digitized high-resolution images of tissue slides.

Now You See It, Now You Dont: Adversarial Vulnerabilities in Computational Pathology

no code implementations14 Jun 2021 Alex Foote, Amina Asif, Ayesha Azam, Tim Marshall-Cox, Nasir Rajpoot, Fayyaz Minhas

Deep learning models are routinely employed in computational pathology (CPath) for solving problems of diagnostic and prognostic significance.

Learning Neural Activations

2 code implementations27 Dec 2019 Fayyaz ul Amir Afsar Minhas, Amina Asif

An artificial neuron is modelled as a weighted summation followed by an activation function which determines its output.

Generalized Learning with Rejection for Classification and Regression Problems

no code implementations3 Nov 2019 Amina Asif, Fayyaz ul Amir Afsar Minhas

We have demonstrated the applicability and effectiveness of the method on synthetically generated data as well as benchmark datasets from UCI machine learning repository for both classification and regression problems.

An embarrassingly simple approach to neural multiple instance classification

1 code implementation6 May 2019 Amina Asif, Fayyaz ul Amir Afsar Minhas

Multiple Instance Learning (MIL) is a weak supervision learning paradigm that allows modeling of machine learning problems in which labels are available only for groups of examples called bags.

Ten ways to fool the masses with machine learning

no code implementations7 Jan 2019 Fayyaz Minhas, Amina Asif, Asa Ben-Hur

If you want to tell people the truth, make them laugh, otherwise they'll kill you.

A Generalized Meta-loss function for regression and classification using privileged information

no code implementations16 Nov 2018 Amina Asif, Muhammad Dawood, Fayyaz ul Amir Afsar Minhas

Learning using privileged information (LUPI) is a powerful heterogenous feature space machine learning framework that allows a machine learning model to learn from highly informative or privileged features which are available during training only to generate test predictions using input space features which are available both during training and testing.

Machine Learning with Abstention for Automated Liver Disease Diagnosis

no code implementations11 Nov 2018 Kanza Hamid, Amina Asif, Wajid Abbasi, Durre Sabih, Fayyaz Minhas

For this purpose, we have implemented a machine learning model that can not only generate labels (normal and abnormal) for a given ultrasound image but it can also detect when its prediction is likely to be incorrect.

Training large margin host-pathogen protein-protein interaction predictors

no code implementations21 Nov 2017 Abdul Hannan Basit, Wajid Arshad Abbasi, Amina Asif, Fayyaz ul Amir Afsar Minhas

We have also developed a web server for our HPI predictor called HoPItor (Host Pathogen Interaction predicTOR) that can predict interactions between human and viral proteins.

pyLEMMINGS: Large Margin Multiple Instance Classification and Ranking for Bioinformatics Applications

no code implementations14 Nov 2017 Amina Asif, Wajid Arshad Abbasi, Farzeen Munir, Asa Ben-Hur, Fayyaz ul Amir Afsar Minhas

Motivation: A major challenge in the development of machine learning based methods in computational biology is that data may not be accurately labeled due to the time and resources required for experimentally annotating properties of proteins and DNA sequences.
