This is an unofficial PyTorch implementation by Ignacio Oguiza (oguiza@gmail.com) based on **Wang, Z., Yan, W., & Oates, T. (2017, May). Time series classification from scratch with deep neural networks: A strong baseline. In 2017 international joint conference on neural networks (IJCNN) (pp. 1578-1585). IEEE.** and **Fawaz, H. I., Forestier, G., Weber, J., Idoumghar, L., & Muller, P. A. (2019). Deep learning for time series classification: a review. Data Mining and Knowledge Discovery, 33(4), 917-963.**. Official FCN TensorFlow implementation: https://github.com/hfawaz/dl-4-tsc/blob/master/classifiers/fcn.py. Note: kernel filter size 8 has been replaced by 7 (since I believe it's a bug).
