Call for Papers CEC2015 Special Session "Nature-Inspired Deep Learning"

Special Session for IEEE CEC 2015

 

Aim

Deep learning is a study of non-linear multi-layer neural network structures and training algorithms. Deep learning emerged as a discipline from the breakthrough research by G. Hinton published in 2006 [1]. The purpose of deep (multi-layer) networks is to extract features from the training data and learn hierarchical representations of the data [2]. Hierarchical representations are more robust and reusable than the classifier rules obtained through shallow learning. Deep neural networks are also more biologically plausible [3]. To date, deep learning achieved impressive results in such application areas as speech recognition and image recognition, significantly outperforming shallow learning methods [4], [5].

Most existing deep learning techniques use the backpropagation algorithm first introduced by P. Werbos in 1974 [6]. A well-known problem of this method applied to deep learning is the vanishing of the gradients at the backpropagation step of the algorithm [7]. Many nature-inspired algorithms such as particle swarm optimisation and evolutionary optimisation are independent of the gradient information. This quality gives nature-inspired algorithms a potential advantage over backpropagation in the deep learning paradigm.

Nature-inspired algorithms have been successfully applied to neural network training in the past [8], [9], [10]. However, applications of the nature-inspired methods to deep learning are still very limited. Training deep neural networks is a challenging task due to the inherent high dimensionality. The aim of this special session is to discuss the existing nature-inspired approaches to deep learning, to identify problems that arise, and to encourage research in this new and exciting field of computational intelligence.

  • Applications of evolutionary algorithms to deep learning
  • Applications of swarm-based algorithms to deep learning
