Expliquer les prédictions des réseaux de neurones par l'exploration de l'espace de représentation et de la frontière de décision à l'aide d'EBBE-Text
Abstract
In text classification, many recent works deal with the interpretation of neural networks
by the production of prediction explanations. In this context, EBBE-Text offers an interactive
visualization of the decision boundary, positionings of texts with respect to it (and thus the
certainty of a network in its predictions), paths leading from a text to the decision boundary,
information concerning the proximity between texts, trought different localities in the text
representation space. These information make it possible to intuit how the classification neural
network functions and thus helps in its interpretability. Our method creates data on the decision
boundary and then uses simplistic fuzzy sets to create a graph before linearly aligning the
created data on the decision boundary. Finally an iterative process places the input data around
the linear arrangements of the boundary data.
