Mitigating shortage of labeled data using clustering-based active learning with diversity exploration

1 code implementation6 Jul 2022 Xuyang Yan, Shabnam Nazmi, Biniam Gebru, Mohd Anwar, Abdollah Homaifar, Mrinmoy Sarkar, Kishor Datta Gupta

In this paper, we proposed a new clustering-based active learning framework, namely Active Learning using a Clustering-based Sampling (ALCS), to address the shortage of labeled data.

A Robust Completed Local Binary Pattern (RCLBP) for Surface Defect Detection

no code implementations7 Dec 2021 Nana Kankam Gyimah, Abenezer Girma, Mahmoud Nabil Mahmoud, Shamila Nateghi, Abdollah Homaifar, Daniel Opoku

Our approach uses a combination of Non-Local (NL) means filter with wavelet thresholding and Completed Local Binary Pattern (CLBP) to extract robust features which are fed into classifiers for surface defects detection.

The North Carolina Agriculture and Technical State University (NC A&T) in collaboration with Georgia Tech Research Institute (GTRI) has developed methodologies for creating simulation-based technology tools that are capable of inferring the perceptions and behavioral states of autonomous systems.

A Supervised Feature Selection Method For Mixed-Type Data using Density-based Feature Clustering

no code implementations10 Nov 2021 Xuyang Yan, Mrinmoy Sarkar, Biniam Gebru, Shabnam Nazmi, Abdollah Homaifar

In this paper, a supervised feature selection method using density-based feature clustering (SFSDFC) is proposed to obtain an appropriate final feature subset for mixed-type data.
