On the Stability of a non-hyperbolic nonlinear map with non-bounded set of non-isolated fixed points with applications to Machine Learning

1 code implementation5 Jan 2024 Roberta Hansen, Matias Vera, Lautaro Estienne, Luciana Ferrer, Pablo Piantanida

This paper deals with the convergence analysis of the SUCPA (Semi Unsupervised Calibration through Prior Adaptation) algorithm, defined from a first-order non-linear difference equations, first developed to correct the scores output by a supervised machine learning classifier.

Unsupervised Calibration through Prior Adaptation for Text Classification using Large Language Models

no code implementations13 Jul 2023 Lautaro Estienne, Luciana Ferrer, Matías Vera, Pablo Piantanida

These models are usually trained with a very large amount of unsupervised text data and adapted to perform a downstream natural language task using methods like fine-tuning, calibration or in-context learning.

Towards an Hybrid Hodgkin-Huxley Action Potential Generation Model

no code implementations15 Mar 2023 Lautaro Estienne

Mathematical models for the generation of the action potential can improve the understanding of physiological mechanisms that are consequence of the electrical activity in neurons.

Cross-domain Sentiment Classification in Spanish

no code implementations15 Mar 2023 Lautaro Estienne, Matias Vera, Leonardo Rey Vega

In this work we perform a study on the ability of a classification system trained with a large database of product reviews to generalize to different Spanish domains.
