The following paper has been accepted to the 28th International Conference on Artificial Neural Networks (ICANN 2019) as an oral presentation. In this paper, we propose a method to control the architecture complexity by adding the penalty term in the dynamic optimization method of neural network structures [Shirakawa et al. 2018].

Our paper, “Dynamic Optimization of Neural Network Structures Using Probabilistic Modeling”, has been accepted to the Thirty-Second AAAI Conference on Artificial Intelligence (AAAI-18). This paper proposes the framework to dynamically optimize the neural network structure during the training using gradient-based method.

We won the Best Paper Award of Evolutionary Machine Learning (EML) Track in GECCO 2017! The title of the award paper is “A Genetic Programming Approach to Designing Convolutional Neural Network Architectures”. This paper achieved to find high-performance architectures of the convolutional neural networks by the genetic programming with the reasonable computational resource.
