Impact Of Missing Data Imputation On The Fairness And Accuracy Of Graph Node Classifiers

1 code implementation1 Nov 2022 Haris Mansoor, Sarwan Ali, Shafiq Alam, Muhammad Asad Khan, Umair ul Hassan, Imdadullah Khan

In this paper, we analyze the effect on fairness in the context of graph data (node attributes) imputation using different embedding and neural network methods.

Computing Graph Descriptors on Edge Streams

no code implementations2 Sep 2021 Zohair Raza Hassan, Sarwan Ali, Imdadullah Khan, Mudassir Shabbir, Waseem Abbas

Operating on edge streams allows us to avoid storing the entire graph in memory, and controlling the sample size enables us to keep the runtime of our algorithms within desired bounds.

A k-mer Based Approach for SARS-CoV-2 Variant Identification

no code implementations7 Aug 2021 Sarwan Ali, Bikram Sahoo, Naimat Ullah, Alexander Zelikovskiy, Murray Patterson, Imdadullah Khan

With the rapid spread of the novel coronavirus (COVID-19) across the globe and its continuous mutation, it is of pivotal importance to design a system to identify different known (and unknown) variants of SARS-CoV-2.

Effect of Analysis Window and Feature Selection on Classification of Hand Movements Using EMG Signal

no code implementations2 Feb 2020 Asad Ullah, Sarwan Ali, Imdadullah Khan, Muhammad Asad Khan, Safiullah Faizullah

In this paper, we investigate the effect of the analysis window and feature selection on classification accuracy of different hand and wrist movements using time-domain features.

Estimating Descriptors for Large Graphs

1 code implementation28 Jan 2020 Zohair Raza Hassan, Mudassir Shabbir, Imdadullah Khan, Waseem Abbas

State-of-the-art algorithms for computing descriptors require the entire graph to be in memory, entailing a huge memory footprint, and thus do not scale well to increasing sizes of real-world networks.

Short-Term Load Forecasting Using AMI Data

no code implementations28 Dec 2019 Haris Mansoor, Sarwan Ali, Imdadullah Khan, Naveed Arshad, Muhammad Asad Khan, Safiullah Faizullah

A prominent feature of \textsc{fmf} is that it works at any level of user-specified granularity, both in the temporal (from a single hour to days) and spatial dimensions (a single household to groups of consumers).
