AnomalyDetectionOnRisk

A comparison between 5 models for performing anomaly detection on financial risk measures and returns. These experiments were conducted as part of the degree project Anomaly Detection for Portfolio Risk Management, which can be found in Simon_Westerlind_Masters_Thesis.pdf or on Diva.

Prerequisites

  1. Install Conda.
  2. Install the conda requirements with
conda install --yes --file requirements.txt

  1. Install the rugarch package. Elsewise the ARMA-GARCH will not work.

  2. Install NuPIC.

  3. Copy the returns_and_risk folder which exists in ./htm and place it in /nupic/examples/opf/clients/

Run

To run the EWMA, ARMA-GARCH, LSTM and HardLimits, run

python garch_long.py

while in the ./garch folder. Thereafter run

python run.py --plot

The HTM can be run with the same command from within /nupic/examples/opf/clients/returns_and_risk/anomaly/one_returns. However first you must create a separate conda environment and install:

conda install --yes --file requirements_htm.txt
