TiSeLaC ECML/PKDD 2017 discovery challenge solution

This repo hosts the first-place solution to the discovery challenge on Time Series Land cover Classification (TiSeLaC), organized in conjunction of ECML-PKDD 2017.

The challenge consists in predicting the Land Cover class of a set of pixels given their image time series data acquired by the satellites. We propose an end-to-end learning approach leveraging both temporal and spatial information and requiring very little data preprocessing and feature engineering.

architecture

The architecture---ranked first out of 21 teams---comprises different modules using dense multi-layer perceptrons, one-dimensional dilated convolutional and fully connected one-dimensional convolutiona neural layers.

requirements

To run, the following libraries are required:

• numpy (1.10+),
• sklearn (0.18+),
• keras (2.0+) (we used Theano as a backend).

usage

To train on the full training data, and predict for the whole test, you can run:

ipython -- deep-tsc.py
