Shared Task in Evaluating Accuracy: Leveraging Pre-Annotations in the Validation Process

no code implementations INLG (ACL) 2021 Nicolas Garneau, Luc Lamontagne

Our submission consists in fact of two submissions; we first analyze solely the performance of the rules and classifiers (pre-annotations), and then the human evaluation aided by the former pre-annotations using the web interface (hybrid).

Assessing the Impact of Sequence Length Learning on Classification Tasks for Transformer Encoder Models

no code implementations16 Dec 2022 Jean-Thomas Baillargeon, Luc Lamontagne

Classification algorithms using Transformer architectures can be affected by the sequence length learning problem whenever observations from different classes have a different length distribution.

Preventing RNN from Using Sequence Length as a Feature

no code implementations16 Dec 2022 Jean-Thomas Baillargeon, Hélène Cossette, Luc Lamontagne

Recurrent neural networks are deep learning topologies that can be trained to classify long documents.

Multinational Address Parsing: A Zero-Shot Evaluation

1 code implementation7 Dec 2021 Marouane Yassine, David Beauchemin, François Laviolette, Luc Lamontagne

While these models yield notable results, previous work on neural networks has only focused on parsing addresses from a single source country.

Geographic ratemaking with spatial embeddings

no code implementations26 Apr 2021 Christopher Blier-Wong, Hélène Cossette, Luc Lamontagne, Etienne Marceau

This paper presents a method based on data (instead of smoothing historical insurance claim losses) to construct a geographic ratemaking model.

Rethinking Representations in P&C Actuarial Science with Deep Neural Networks

no code implementations11 Feb 2021 Christopher Blier-Wong, Jean-Thomas Baillargeon, Hélène Cossette, Luc Lamontagne, Etienne Marceau

Insurance companies gather a growing variety of data for use in the insurance process, but most traditional ratemaking models are not designed to support them.

Leveraging Subword Embeddings for Multinational Address Parsing

3 code implementations29 Jun 2020 Marouane Yassine, David Beauchemin, François Laviolette, Luc Lamontagne

We propose an approach in which we employ subword embeddings and a Recurrent Neural Network architecture to build a single model capable of learning to parse addresses from multiple countries at the same time while taking into account the difference in languages and address formatting systems.

Attending Form and Context to Generate Specialized Out-of-VocabularyWords Representations

no code implementations14 Dec 2019 Nicolas Garneau, Jean-Samuel Leboeuf, Yuval Pinter, Luc Lamontagne

We propose a new contextual-compositional neural network layer that handles out-of-vocabulary (OOV) words in natural language processing (NLP) tagging tasks.

Predicting and interpreting embeddings for out of vocabulary words in downstream tasks

no code implementations WS 2018 Nicolas Garneau, Jean-Samuel Leboeuf, Luc Lamontagne

We propose a novel way to handle out of vocabulary (OOV) words in downstream natural language processing (NLP) tasks.
