Update 02-Jan-2017
I updated this repo. Now it works with Tensorflow 0.12. In this readme I comment on some new benchmarks
LSTM for time-series classification
This post implements a Long Short-term memory for time series classification(LSTM). An LSTM is the extension of the classical Recurrent Neural Network. It has more flexibility and interpretable features such as a memory it can read, write and forget.
Aim
This repo aims to show the minimal Tensorflow code for proper time series classification. The main function loads the data and iterates over training steps. The tsc_model.py scripts contains the actual model. This repo contrasts with another project where I implement a similar script using convolutional neural networks as the model
Data and results
The code generalizes for any of the UCR time series. With the parameter dataset you can run the code on any of their datasets. For your interests, you may compare performances with the nice overview in this paper. They benchmark their CNN and other models on many of the UCR time series datasets This code works amongst others for
- Two_Patterns where it achieves state-of-the-art, bein 100% test accuracy
- ChlorineConcentration where it achieves state-of-the-art, being 80% test accuracy
Credits
Credits for this project go to Tensorflow for providing a strong example, the UCR archive for the dataset and my friend Ryan for strong feedback.
