Recurrence-Aware Long-Term Cognitive Network for Explainable Pattern Classification

1 code implementation7 Jul 2021 Gonzalo Nápoles, Yamisleydi Salgueiro, Isel Grau, Maikel Leon Espinosa

Besides, we propose a recurrence-aware decision model that evades the issues posed by the unique fixed point while introducing a deterministic learning algorithm to compute the tunable parameters.

Long Short-term Cognitive Networks

1 code implementation30 Jun 2021 Gonzalo Nápoles, Isel Grau, Agnieszka Jastrzebska, Yamisleydi Salgueiro

In this paper, we present a recurrent neural system named Long Short-term Cognitive Networks (LSTCNs) as a generalization of the Short-term Cognitive Network (STCN) model.

An interpretable semi-supervised classifier using two different strategies for amended self-labeling

no code implementations26 Jan 2020 Isel Grau, Dipankar Sengupta, Maria M. Garcia Lorenzo, Ann Nowe

In the context of some machine learning applications, obtaining data instances is a relatively easy process but labeling them could become quite expensive or tedious.
