GEN Model: An Alternative Approach to Deep Neural Network Models [article]

Jiawei Zhang and Limeng Cui and Fisher B. Gouza
2018 arXiv   pre-print
In this paper, we introduce an alternative approach, namely GEN (Genetic Evolution Network) Model, to the deep learning models.  ...  Instead of building one single deep model, GEN adopts a genetic-evolutionary learning strategy to build a group of unit models generations by generations.  ...  In this paper, we propose the GEN (Genetic Evolution Network) model, which can work as an alternative approach to the deep learning models.  ...

GEN: highly efficient SMILES explorer using autodidactic generative examination networks

Ruud van Deursen, Peter Ertl, Igor V. Tetko, Guillaume Godin
2020 Journal of Cheminformatics  
In this study, we introduce Generative Examination Networks (GEN) as a new approach to train deep generative networks for SMILES generation.  ...  Recurrent neural networks have been widely used to generate millions of de novo molecules in defined chemical spaces.  ...  The neural network of the generator is subsequently converted into a generative examination network (GEN). In GENs, the deep generative models autonomously learn to write valid molecular SMILES.  ...

The Efficacy of L_1 Regularization in Two-Layer Neural Networks [article]

Gen Li, Yuantao Gu, Jie Ding
2020 arXiv   pre-print
A crucial problem in neural networks is to select the most appropriate number of hidden neurons and obtain tight statistical risk bounds.  ...  As an alternative to selecting the number of neurons, we theoretically show that L_1 regularization can control the generalization error and sparsify the input dimension.  ...  Second, it would be interesting to emulate the current approach to yield similarly tight risk bounds for deep forward neural networks.  ...
