- Zijian Wang, Yadan Luo, Ruihong Qiu, Zi-Yu Huang, Mahsa Baktash
- Computer ScienceIEEE International Conference on Computer Vision
- 26 August 2021
This paper proposes a style-complement module to enhance the generalization power of the model by synthesizing images from diverse distributions that are complementary to the source ones, and surpasses the state-of-the-art single-DG methods by up to 25.14%.

- Yadan Luo, Zijian Wang, Zi Huang, Mahsa Baktash
- Computer ScienceInternational Conference on Machine Learning
- 22 June 2020
This paper introduces an end-to-end Progressive Graph Learning (PGL) framework where a graph neural network with episodic training is integrated to suppress underlying conditional shift and adversarial learning is adopted to close the gap between the source and target distributions.

This paper introduces a Distribution-Matching Embedding approach: An unsupervised domain adaptation method that overcomes this issue by mapping the data to a latent space where the distance between the empirical distributions of the source and target examples is minimized.
Domain Adaptation on the Statistical Manifold

- Computer ScienceIEEE Conference on Computer Vision and Pattern…
- 23 June 2014
This framework introduces a sample selection method and a subspace-based method for unsupervised domain adaptation, and shows that both these manifold-based techniques outperform the corresponding approaches based on the MMD.
Beyond Gauss: Image-Set Matching on the Riemannian Manifold of PDFs
- M. Harandi, M. Salzmann, Mahsa Baktash
- Computer ScienceIEEE International Conference on Computer Vision
- 31 July 2015
This work proposes to go beyond state-of-the-art image-set matching techniques and model image-sets as probability distribution functions (PDFs) using kernel density estimators and introduces valid positive definite kernels on the statistical manifolds.

- Mohammad Mahfujur Rahman, C. Fookes, Mahsa Baktash, S. Sridharan
- Computer ScienceDomain Adaptation for Visual Understanding
- 2 January 2019
A new unsupervised deep domain adaptation method based on the alignment of second order statistics (covariances) as well as maximum mean discrepancy of the source and target data with a two stream Convolutional Neural Network (CNN).
Implicit Surface Representations As Layers in Neural Networks
- Mateusz Michalkiewicz, J. K. Pontes, Dominic Jack, Mahsa Baktash, Anders P. Eriksson
- Computer ScienceIEEE International Conference on Computer Vision
- 1 October 2019
This work proposes a novel formulation that permits the use of implicit representations of curves and surfaces, of arbitrary topology, as individual layers in Neural Network architectures with end-to-end trainability, and proposes to represent the output as an oriented level set of a continuous and discretised embedding function.

- S. Erfani, Mahsa Baktash, S. Rajasegarar, S. Karunasekera, C. Leckie
- Computer ScienceAAAI Conference on Artificial Intelligence
- 25 January 2015
This paper proposes the RandomisedOne-class SVM (R1SVM), which is an efficient and scalable anomaly detection technique that can be trained on large-scale datasets and achieves comparable or better accuracy to deep autoen-coder and traditional kernelised approaches for anomaly de-tection.
Robust Domain Generalisation by Enforcing Distribution Invariance
- S. Erfani, Mahsa Baktash, K. Ramamohanarao
- Computer ScienceInternational Joint Conference on Artificial…
- 9 July 2016
This work proposes Elliptical Summary Randomisation (ESRand), an efficient domain generalisation approach that comprises of a randomised kernel and elliptical data summarisation that learns a domain interdependent projection to a latent subspace that minimises the existing biases to the data while maintaining the functional relationship between domains.
