Topological Semantic Mapping by Consolidation of Deep Visual Features

no code implementations24 Jun 2021 Ygor C. N. Sousa, Hansenclever F. Bassani

In contrast, this work introduces a topological semantic mapping method that uses deep visual features extracted by a CNN (GoogLeNet), from 2D images captured in multiple views of the environment as the robot operates, to create, through averages, consolidated representations of the visual features acquired in the regions covered by each topological node.

MOEA/D with Uniformly Randomly Adaptive Weights

no code implementations15 Aug 2019 Lucas R. C. de Farias, Pedro H. M. Braga, Hansenclever F. Bassani, Aluizio F. R. Araújo

In this paper, we propose the MOEA/D with Uniformly Randomly Adaptive Weights (MOEA/DURAW) which uses the Uniformly Randomly method as an approach to subproblems generation, allowing a flexible population size even when working with many objective problems.

Self-Organizing Maps with Variable Input Length for Motif Discovery and Word Segmentation

no code implementations7 Aug 2019 Raphael C. Brito, Hansenclever F. Bassani

Time Series Motif Discovery (TSMD) is defined as searching for patterns that are previously unknown and appear with a given frequency in time series.

A Semi-Supervised Self-Organizing Map with Adaptive Local Thresholds

1 code implementation1 Jul 2019 Pedro H. M. Braga, Hansenclever F. Bassani

Also, it is important to develop methods that are easy to parameterize in a way that is robust to the different characteristics of the data at hand.

A Semi-Supervised Self-Organizing Map for Clustering and Classification

1 code implementation1 Jul 2019 Pedro H. M. Braga, Hansenclever F. Bassani

There has been an increasing interest in semi-supervised learning in the recent years because of the great number of datasets with a large number of unlabeled data but only a few labeled samples.

A Neural Network Architecture for Learning Word-Referent Associations in Multiple Contexts

no code implementations20 May 2019 Hansenclever F. Bassani, Aluizio F. R. Araujo

This article proposes a biologically inspired neurocomputational architecture which learns associations between words and referents in different contexts, considering evidence collected from the literature of Psycholinguistics and Neurolinguistics.
