Hosted projects on OSIRIM :

SGL Thresh (CERCO - IRIT SAMOVA teams) - March 2020

SGLThresh: Surrogate Gradient Learning of Thresholds.
It is a question of fixing optimal thresholds for a multi-label classification problem. Thresholds allow you to assign a label or not based on continuous probabilities. We want to find the thresholds which minimize a certain cost function by using a gradient descent. The thresholding function being non-differentiable, when calculating the gradient it is claimed that a sigmoid was used instead.

REAM (IRIT ADRIA and MELODI teams) - January 2020

Explicit Reasoning and Learning on Medical Imagery.
The project objective concerns the validation of neural network architecture for the automatic classification of histopathological images, and verification of learning incrementality hypotheses.
This project is part of a thesis on the interaction between the learning system and the explicit reasoning system. The first part of the thesis aims to design an automatic image classifier using deep learning. In a second step, explicit knowledge will be added in the form of ontologies or expert system rules. Thirdly we will develop the interaction between the two systems.

ANITI - DAML (Université Fédérale de Toulouse MIP) - November 2019

Data assimilation (DA) is a proven technique for monitoring a dynamic system through the use of a parameterized representation of its dynamics and physical observations. It is traditionally presented in a Bayesian context.
Supervised Deep Machine Learning (ML) allows for weight-wise label prediction of a neural network using training examples.
The central question for the Chair is: how can we introduce an approximate dynamic into neural networks? Conversely, how can we introduce deep learning in AD to be able to do without dynamics and obtain better algorithms. In both cases, what are the expected performances?
The purpose of the Chair is to propose hybridization algorithms by validating them on physical equations representative of real equations..
