PSO-Convolutional Neural Networks with Heterogeneous Learning Rate

1 code implementation20 May 2022 Nguyen Huu Phong, Augusto Santos, Bernardete Ribeiro

In such framework, the vector of weights of each ConvNet is typically cast as the position of a particle in phase space whereby PSO collaborative dynamics intertwines with Stochastic Gradient Descent (SGD) in order to boost training performance and generalization.

Rethinking Recurrent Neural Networks and Other Improvements for Image Classification

1 code implementation30 Jul 2020 Nguyen Huu Phong, Bernardete Ribeiro

In addition, we extend the training strategy so that our model performs comparably to leading models and can even match the state-of-the-art models on several challenging datasets (e. g., SVHN (0. 99), Cifar-100 (0. 9027) and Cifar-10 (0. 9852)).

Incremental Evolution and Development of Deep Artificial Neural Networks

1 code implementation1 Apr 2020 Filipe Assunção, Nuno Lourenço, Bernardete Ribeiro, Penousal Machado

Despite aiding non-expert users to design and train ANNs, the vast majority of NE approaches disregard the knowledge that is gathered when solving other tasks, i. e., evolution starts from scratch for each problem, ultimately delaying the evolutionary process.

Evolution of Scikit-Learn Pipelines with Dynamic Structured Grammatical Evolution

1 code implementation1 Apr 2020 Filipe Assunção, Nuno Lourenço, Bernardete Ribeiro, Penousal Machado

The deployment of Machine Learning (ML) models is a difficult and time-consuming job that comprises a series of sequential and correlated tasks that go from the data pre-processing, and the design and extraction of features, to the choice of the ML algorithm and its parameterisation.
