mRAT-SQL+GAP:A Portuguese Text-to-SQL Transformer

1 code implementation7 Oct 2021 Marcelo Archanjo José, Fabio Gagliardi Cozman

A large number of techniques are geared towards the English language; in this work, we thus investigated translation to SQL when input questions are given in the Portuguese language.

A Fully Attention-Based Information Retriever

1 code implementation22 Oct 2018 Alvaro Henrique Chaim Correia, Jorge Luiz Moreira Silva, Thiago de Castro Martins, Fabio Gagliardi Cozman

Recurrent neural networks are now the state-of-the-art in natural language processing because they can build rich contextual representations and process texts of arbitrary length.

Interpreting Embedding Models of Knowledge Bases: A Pedagogical Approach

1 code implementation20 Jun 2018 Arthur Colombini Gusmão, Alvaro Henrique Chaim Correia, Glauber De Bona, Fabio Gagliardi Cozman

Knowledge bases are employed in a variety of applications from natural language processing to semantic web search; alas, in practice their usefulness is hurt by their incompleteness.

On the Semantics and Complexity of Probabilistic Logic Programs

no code implementations31 Jan 2017 Fabio Gagliardi Cozman, Denis Deratani Mauá

We examine the meaning and the complexity of probabilistic logic programs that consist of a set of rules and a set of independent probabilistic facts (that is, programs based on Sato's distribution semantics).

The Complexity of Bayesian Networks Specified by Propositional and Relational Languages

no code implementations4 Dec 2016 Fabio Gagliardi Cozman, Denis Deratani Mauá

We examine the complexity of inference in Bayesian networks specified by logical languages.

First-Order Bayesian Network Specifications Capture the Complexity Class PP

no code implementations12 Sep 2016 Fabio Gagliardi Cozman

The point of this note is to prove that a language is in the complexity class PP if and only if the strings of the language encode valid inferences in a Bayesian network defined using function-free first-order logic with equality.
