Team Cogitat at NeurIPS 2021: Benchmarks for EEG Transfer Learning Competition

no code implementations1 Feb 2022 Stylianos Bakas, Siegfried Ludwig, Konstantinos Barmpas, Mehdi Bahri, Yannis Panagakis, Nikolaos Laskaris, Dimitrios A. Adamos, Stefanos Zafeiriou

The second task required to transfer models trained on the subjects of one or more source motor imagery datasets to perform inference on two target datasets, providing a small set of personalized calibration data for multiple test subjects.

Shape My Face: Registering 3D Face Scans by Surface-to-Surface Translation

no code implementations16 Dec 2020 Mehdi Bahri, Eimear O' Sullivan, Shunwang Gong, Feng Liu, Xiaoming Liu, Michael M. Bronstein, Stefanos Zafeiriou

Compared to the previous state-of-the-art learning algorithms for non-rigid registration of face scans, SMF only requires the raw data to be rigidly aligned (with scaling) with a pre-defined face template.

Robust Kronecker Component Analysis

no code implementations18 Jan 2018 Mehdi Bahri, Yannis Panagakis, Stefanos Zafeiriou

Dictionary learning and component analysis models are fundamental for learning compact representations that are relevant to a given task (feature extraction, dimensionality reduction, denoising, etc.).

Robust Kronecker-Decomposable Component Analysis for Low-Rank Modeling

1 code implementation ICCV 2017 Mehdi Bahri, Yannis Panagakis, Stefanos Zafeiriou

In this paper, we introduce a new robust decomposition of images by combining ideas from sparse dictionary learning and PCP.
