LegalNLP -- Natural Language Processing methods for the Brazilian Legal Language

1 code implementation5 Oct 2021 Felipe Maia Polo, Gabriel Caiaffa Floriano Mendonça, Kauê Capellato J. Parreira, Lucka Gianvechio, Peterson Cordeiro, Jonathan Batista Ferreira, Leticia Maria Paz de Lima, Antônio Carlos do Amaral Maia, Renato Vicente

We present and make available pre-trained language models (Phraser, Word2Vec, Doc2Vec, FastText, and BERT) for the Brazilian legal language, a Python package with functions to facilitate their use, and a set of demonstrations/tutorials containing some applications involving them.

An experiment on the mechanisms of racial bias in ML-based credit scoring in Brazil

no code implementations11 Nov 2020 Ramon Vilarino, Renato Vicente

We dissect an experimental credit scoring model developed with real data and demonstrate - without access to protected attributes - how the use of location information introduces racial bias.

Effective Sample Size, Dimensionality, and Generalization in Covariate Shift Adaptation

1 code implementation2 Oct 2020 Felipe Maia Polo, Renato Vicente

Hence, in this paper, we focus on building a unified view connecting the ESS, data dimensionality, and generalization in the context of covariate shift adaptation.

Restricted Boltzmann Machine Flows and The Critical Temperature of Ising models

1 code implementation17 Jun 2020 Rodrigo Veiga, Renato Vicente

We explore alternative experimental setups for the iterative sampling (flow) from Restricted Boltzmann Machines (RBM) mapped on the temperature space of square lattice Ising models by a neural network thermometer.

Age-structured estimation of COVID-19 ICU demand from low quality data

1 code implementation8 Jun 2020 Rodrigo Veiga, Rodrigo Murta, Renato Vicente

We sample aggravated cases following age-structured probabilities from confirmed cases and use ICU occupation data to find a subnotification factor.
