nntimeseries

The repository provides the code for the paper Autoregressive Convolutional Neural Networks for Asynchronous Time Series, as well as general code for running grid serach on keras models.

Files 'nnts/models/{CNN, LSTM, LSTM2, LR, SOCNN}.py' provide code for testing respective models, with the last one implementing the proposed Significance-Offset CNN and LSTM2 implementing multi-layer LSTM.

Basic Usage

Each of the model files can be run as a script, e.g.

• python ./CNN.py --dataset=artificial # default save file
• python ./SOCNN.py --dataset=household --save_file=results/household_0.pkl

Parameters for grid search can be specified in each of the above files.

Each of these files defines a model class that can be imported and used on external dataset, as shown in example.ipynb file.

The repository supports optimization of the above models on artifical multivariate noisy AR time series and household electricity conspumption dataset https://archive.ics.uci.edu/ml/datasets/Individual+household+electric+power+consumption The dataset has to be specified alongside the paremeters in each of the files listed above.

To generate aritficial datasets used in model evaluation in the paper, run 'python generate_artifical.py'.

Requirements
