Mitigating analytical variability in fMRI results with style transfer

no code implementations4 Apr 2024 Elodie Germani, Elisa Fromont, Camille Maumet

We propose a novel approach to improve the reproducibility of neuroimaging results by converting statistic maps across different functional MRI pipelines.

The HCP multi-pipeline dataset: an opportunity to investigate analytical variability in fMRI data analysis

no code implementations22 Dec 2023 Elodie Germani, Elisa Fromont, Pierre Maurel, Camille Maumet

Results of functional Magnetic Resonance Imaging (fMRI) studies can be impacted by many sources of variability including differences due to: the sampling of the participants, differences in acquisition protocols and material but also due to different analytical choices in the processing of the fMRI data.

Uncovering communities of pipelines in the task-fMRI analytical space

no code implementations11 Dec 2023 Elodie Germani, Elisa Fromont, Camille Maumet

Analytical workflows in functional magnetic resonance imaging are highly flexible with limited best practices as to how to choose a pipeline.

On the benefits of self-taught learning for brain decoding

no code implementations19 Sep 2022 Elodie Germani, Elisa Fromont, Camille Maumet

We study the benefits of using a large public neuroimaging database composed of fMRI statistic maps, in a self-taught learning framework, for improving brain decoding on new tasks.

UniRank: Unimodal Bandit Algorithm for Online Ranking

no code implementations2 Aug 2022 Camille-Sovanneary Gauthier, Romaric Gaudel, Elisa Fromont

The semi-bandit version, where a full matching is sampled at each iteration, has been addressed by \cite{ADMA}, creating an algorithm with an expected regret matching $O(\frac{L\log(L)}{\Delta}\log(T))$ with $2L$ players, $T$ iterations and a minimum reward gap $\Delta$.

Discovering Useful Compact Sets of Sequential Rules in a Long Sequence

no code implementations15 Sep 2021 Erwan Bourrand, Luis Galárraga, Esther Galbrun, Elisa Fromont, Alexandre Termier

We are interested in understanding the underlying generation process for long sequences of symbolic events.

Localize to Classify and Classify to Localize: Mutual Guidance in Object Detection

1 code implementation29 Sep 2020 Heng Zhang, Elisa Fromont, Sébastien Lefevre, Bruno Avignon

Most deep learning object detectors are based on the anchor mechanism and resort to the Intersection over Union (IoU) between predefined anchor boxes and ground truth boxes to evaluate the matching quality between anchors and objects.

Multispectral Fusion for Object Detection with Cyclic Fuse-and-Refine Blocks

1 code implementation26 Sep 2020 Heng Zhang, Elisa Fromont, Sébastien Lefevre, Bruno Avignon

Multispectral images (e. g. visible and infrared) may be particularly useful when detecting objects with the same model in different environments (e. g. day/night outdoor scenes).

Learning Interpretable Shapelets for Time Series Classification through Adversarial Regularization

no code implementations3 Jun 2019 Yichang Wang, Rémi Emonet, Elisa Fromont, Simon Malinowski, Etienne Menager, Loïc Mosser, Romain Tavenard

Times series classification can be successfully tackled by jointly learning a shapelet-based representation of the series in the dataset and classifying the series according to this representation.

Residual Conv-Deconv Grid Network for Semantic Segmentation

1 code implementation25 Jul 2017 Damien Fourure, Rémi Emonet, Elisa Fromont, Damien Muselet, Alain Tremeau, Christian Wolf

However, for semantic image segmentation, where the task consists in providing a semantic class to each pixel of an image, feature maps reduction is harmful because it leads to a resolution loss in the output prediction.
