A comparison between CNNs and WFAs for Sequence Classification

no code implementations EMNLP (sustainlp) 2020 Ariadna Quattoni, Xavier Carreras

We compare a classical CNN architecture for sequence classification involving several convolutional and max-pooling layers against a simple model based on weighted finite state automata (WFA).

Analyzing Text Representations by Measuring Task Alignment

no code implementations31 May 2023 Cesar Gonzalez-Gutierrez, Audi Primadhanty, Francesco Cazzaro, Ariadna Quattoni

Our experiments on text classification validate our hypothesis by showing that task alignment can explain the classification performance of a given representation.

Are Deep Sequence Classifiers Good at Non-Trivial Generalization?

no code implementations24 Oct 2022 Francesco Cazzaro, Ariadna Quattoni, Xavier Carreras

We focus on sparse sequence classification, that is problems in which the target class is rare and compare three deep learning sequence classification models.

Translate First Reorder Later: Leveraging Monotonicity in Semantic Parsing

1 code implementation10 Oct 2022 Francesco Cazzaro, Davide Locatelli, Ariadna Quattoni, Xavier Carreras

Prior work in semantic parsing has shown that conventional seq2seq models fail at compositional generalization tasks.

Measuring Alignment Bias in Neural Seq2Seq Semantic Parsers

1 code implementation *SEM (NAACL) 2022 Davide Locatelli, Ariadna Quattoni

Prior to deep learning the semantic parsing community has been interested in understanding and modeling the range of possible word alignments between natural language sentences and their corresponding meaning representations.

Interpolated Spectral NGram Language Models

no code implementations ACL 2019 Ariadna Quattoni, Xavier Carreras

Spectral models for learning weighted non-deterministic automata have nice theoretical and algorithmic properties.

A Maximum Matching Algorithm for Basis Selection in Spectral Learning

no code implementations9 Jun 2017 Ariadna Quattoni, Xavier Carreras, Matthias Gallé

Spectral algorithms reduce the learning problem to the task of computing an SVD decomposition over a special type of matrix called the Hankel matrix.

InToEventS: An Interactive Toolkit for Discovering and Building Event Schemas

no code implementations EACL 2017 Germ{\'a}n Ferrero, Audi Primadhanty, Ariadna Quattoni

Event Schema Induction is the task of learning a representation of events (e. g., bombing) and the roles involved in them (e. g, victim and perpetrator).

Tailoring Word Embeddings for Bilexical Predictions: An Experimental Comparison

no code implementations22 Dec 2014 Pranava Swaroop Madhyastha, Xavier Carreras, Ariadna Quattoni

We investigate the problem of inducing word embeddings that are tailored for a particular bilexical relation.

Unsupervised Spectral Learning of Finite State Transducers

no code implementations NeurIPS 2013 Raphael Bailly, Xavier Carreras, Ariadna Quattoni

Finite-State Transducers (FST) are a standard tool for modeling paired input-output sequences and are used in numerous applications, ranging from computational biology to natural language processing.
