# RANSynCoders
### Industry-Practical Anomaly Detection and Localization for Asynchronous Multivariate Time Series
RANSynCoders (or RANCoders) is an unsupervised deep learning architecture for real-time anomaly detection and localizaiton within large multivariate time series. The method utilizes synchrony-analysis on latent representations for adjusting asynchronous variates fed into an encoder, bootstrap aggregation of decoders, and quantile loss optimization for anomaly inference, localization, as well as optionally creating interpretable charts of anomalies for industy users.
## Getting Started
#### Clone the repo
```
git clone https://github.com/.... && cd RANSynCoders
```
#### Get data
Pooled Server Metrics (PSM) dataset is in the folder `data`.
You can get the public datasets from:
* SMD:
* SWaT:
#### Install dependencies (with python 3.7)
(virtualenv is recommended)
```shell
pip install -r requirements.txt
```
If installing on CUDA-enabled GPU device, add the following packages to the requirements.txt file:
* cudatoolkit == 10.1.243
* cudnn == 7.6.5
* tensorflow-gpu == 2.1.0
#### Running an Example
An example using the attached PSM dataset, including instructions for inference and evaluation, is provided in the notebook `example.ipynb`.
