Improving Semantic Control in Discrete Latent Spaces with Transformer Quantized Variational Autoencoders

1 code implementation1 Feb 2024 Yingji Zhang, Danilo S. Carvalho, Marco Valentino, Ian Pratt-Hartmann, Andre Freitas

Achieving precise semantic control over the latent spaces of Variational AutoEncoders (VAEs) holds significant value for downstream tasks in NLP as the underlying generative mechanisms could be better localised, explained and improved upon.

LlaMaVAE: Guiding Large Language Model Generation via Continuous Latent Sentence Spaces

no code implementations20 Dec 2023 Yingji Zhang, Danilo S. Carvalho, Ian Pratt-Hartmann, André Freitas

Deep generative neural networks, such as Variational AutoEncoders (VAEs), offer an opportunity to better understand and control language models from the perspective of sentence-level latent spaces.

Graph-Induced Syntactic-Semantic Spaces in Transformer-Based Variational AutoEncoders

1 code implementation14 Nov 2023 Yingji Zhang, Marco Valentino, Danilo S. Carvalho, Ian Pratt-Hartmann, André Freitas

The injection of syntactic information in Variational AutoEncoders (VAEs) has been shown to result in an overall improvement of performances and generalisation.

Multi-Relational Hyperbolic Word Embeddings from Natural Language Definitions

1 code implementation12 May 2023 Marco Valentino, Danilo S. Carvalho, André Freitas

Natural language definitions possess a recursive, self-explanatory semantic structure that can support representation learning methods able to preserve explicit conceptual relations and constraints in the latent space.

Learning Disentangled Semantic Spaces of Explanations via Invertible Neural Networks

no code implementations2 May 2023 Yingji Zhang, Danilo S. Carvalho, André Freitas

Disentangled latent spaces usually have better semantic separability and geometrical properties, which leads to better interpretability and more controllable data generation.

Analysis of business process automation as linear time-invariant system network

no code implementations9 Feb 2023 Mauricio Jacobo-Romero, Danilo S. Carvalho, Andre Freitas

In this work, we examined Business Process (BP) production as a signal; this novel approach explores a BP workflow as a linear time-invariant (LTI) system.

Quasi-symbolic explanatory NLI via disentanglement: A geometrical examination

no code implementations12 Oct 2022 Yingji Zhang, Danilo S. Carvalho, Ian Pratt-Hartmann, André Freitas

Disentangling the encodings of neural models is a fundamental aspect for improving interpretability, semantic control, and understanding downstream task performance in Natural Language Processing.

Improving Legal Information Retrieval by Distributional Composition with Term Order Probabilities

no code implementations4 Jun 2017 Danilo S. Carvalho, Duc-Vu Tran, Van-Khanh Tran, Le-Nguyen Minh

In this work, a two-stage method for Legal Information Retrieval is proposed, combining lexical statistics and distributional sentence representations in the context of Competition on Legal Information Extraction/Entailment (COLIEE).

Lexical-Morphological Modeling for Legal Text Analysis

no code implementations3 Sep 2016 Danilo S. Carvalho, Minh-Tien Nguyen, Tran Xuan Chien, Minh Le Nguyen

In the context of the Competition on Legal Information Extraction/Entailment (COLIEE), we propose a method comprising the necessary steps for finding relevant documents to a legal question and deciding on textual entailment evidence to provide a correct answer.
