Unsupervised Domain Adaptation in Person re-ID via k-Reciprocal Clustering and Large-Scale Heterogeneous Environment Synthesis

no code implementations14 Jan 2020 Devinder Kumar, Parthipan Siva, Paul Marchwica, Alexander Wong

As such, there has been a recent focus on unsupervised learning approaches to mitigate the data annotation issue; however, current approaches in literature have limited performance compared to supervised learning approaches as well as limited applicability for adoption in new environments.

Fairest of Them All: Establishing a Strong Baseline for Cross-Domain Person ReID

no code implementations28 Jul 2019 Devinder Kumar, Parthipan Siva, Paul Marchwica, Alexander Wong

There has been recent interest in tackling this challenge using cross-domain approaches, which leverages data from source domains that are different than the target domain.

Beyond Explainability: Leveraging Interpretability for Improved Adversarial Learning

no code implementations21 Apr 2019 Devinder Kumar, Ibrahim Ben-Daya, Kanav Vats, Jeffery Feng, Graham Taylor and, Alexander Wong

In this study, we propose the leveraging of interpretability for tasks beyond purely the purpose of explainability.

SISC: End-to-end Interpretable Discovery Radiomics-Driven Lung Cancer Prediction via Stacked Interpretable Sequencing Cells

no code implementations15 Jan 2019 Vignesh Sankar, Devinder Kumar, David A. Clausi, Graham W. Taylor, Alexander Wong

Conclusion: The SISC radiomic sequencer is able to achieve state-of-the-art results in lung cancer prediction, and also offers prediction interpretability in the form of critical response maps.
