Improving Data Quality with Training Dynamics of Gradient Boosting Decision Trees

1 code implementation20 Oct 2022 Moacir Antonelli Ponti, Lucas de Angelis Oliveira, Mathias Esteban, Valentina Garcia, Juan Martín Román, Luis Argerich

Real world datasets contain incorrectly labeled instances that hamper the performance of the model and, in particular, the ability to generalize out of distribution.

From Imitation to Prediction, Data Compression vs Recurrent Neural Networks for Natural Language Processing

no code implementations1 May 2017 Juan Andrés Laura, Gabriel Masi, Luis Argerich

In recent studies [1][13][12] Recurrent Neural Networks were used for generative processes and their surprising performance can be explained by their ability to create good predictions.
