The impact of data set similarity and diversity on transfer learning success in time series forecasting

no code implementations9 Apr 2024 Claudia Ehrig, Catherine Cleophas, Germain Forestier

Models, pre-trained on a similar or diverse source data set, have become pivotal in enhancing the efficiency and accuracy of time series forecasting on target data sets by leveraging transfer learning.

An automatic framework for fusing information from differently stained consecutive digital whole slide images: A case study in renal histology

no code implementations29 Aug 2020 Odyssee Merveille, Thomas Lampert, Jessica Schmitz, Germain Forestier, Friedrich Feuerhake, Cédric Wemmert

Objective: This article presents an automatic image processing framework to extract quantitative high-level information describing the micro-environment of glomeruli in consecutive whole slide images (WSIs) processed with different staining modalities of patients with chronic kidney rejection after kidney transplantation.

Adversarial Attacks on Deep Neural Networks for Time Series Classification

1 code implementation17 Mar 2019 Hassan Ismail Fawaz, Germain Forestier, Jonathan Weber, Lhassane Idoumghar, Pierre-Alain Muller

Time Series Classification (TSC) problems are encountered in many real life data mining tasks ranging from medicine and security to human activity recognition and food safety.

Transfer learning for time series classification

1 code implementation5 Nov 2018 Hassan Ismail Fawaz, Germain Forestier, Jonathan Weber, Lhassane Idoumghar, Pierre-Alain Muller

Transfer learning for deep neural networks is the process of first training a base network on a source dataset, and then transferring the learned features (the network's weights) to a second network to be trained on a target dataset.

Strategies for Training Stain Invariant CNNs

no code implementations17 Oct 2018 Thomas Lampert, Odyssée Merveille, Jessica Schmitz, Germain Forestier, Friedrich Feuerhake, Cédric Wemmert

By training the network on one commonly used staining modality and applying it to images that include corresponding but differently stained tissue structures, the presented unsupervised strategies demonstrate significant improvements over standard training strategies.

Deep learning for time series classification: a review

7 code implementations12 Sep 2018 Hassan Ismail Fawaz, Germain Forestier, Jonathan Weber, Lhassane Idoumghar, Pierre-Alain Muller

We give an overview of the most successful deep learning applications in various time series domains under a unified taxonomy of DNNs for TSC.

Data augmentation using synthetic data for time series classification with deep residual networks

2 code implementations7 Aug 2018 Hassan Ismail Fawaz, Germain Forestier, Jonathan Weber, Lhassane Idoumghar, Pierre-Alain Muller

This is surprising as the accuracy of deep learning models for TSC could potentially be improved, especially for small datasets that exhibit overfitting, when a data augmentation method is adopted.

Evaluating surgical skills from kinematic data using convolutional neural networks

1 code implementation7 Jun 2018 Hassan Ismail Fawaz, Germain Forestier, Jonathan Weber, Lhassane Idoumghar, Pierre-Alain Muller

The need for automatic surgical skills assessment is increasing, especially because manual feedback from senior surgeons observing junior surgeons is prone to subjectivity and time consuming.

On the Inter-relationships among Drift rate, Forgetting rate, Bias/variance profile and Error

1 code implementation29 Jan 2018 Nayyar A. Zaidi, Geoffrey I. Webb, Francois Petitjean, Germain Forestier

These hypotheses lead to the concept of the sweet path, a path through the 3-d space of alternative drift rates, forgetting rates and bias/variance profiles on which generalization error will be minimized, such that slow drift is coupled with low forgetting and low bias, while rapid drift is coupled with fast forgetting and low variance.
