Abstract

This paper focuses on analysing multiple time series relationships such as correlations between them. We develop a solution for the Connectiomics contest dataset of fluorescence imaging of neural activity recordings — the aim is reconstruction of the wiring between brain neurons. The model is implemented to achieve high evaluation score. Our model took the fourth place in this contest. The performance is similar to the other leading solutions, thus we showed that deep learning methods for time series processing are comparable to the other approaches and have wide opportunities for further improvement. We discuss a range of methods and code optimisations applied for the convolutional neural network for the time series domain.
