discontinuitypy 0.1.1

A python package for identifying and analyzing discontinuities for time series data.

DiscontinuityPy

User Guide

This package is designed to identify and analyze discontinuities in time series data.

1. Finding the discontinuities, see this notebook
   • Corresponding to limited feature extraction / anomaly detection
2. Calculating the properties of the discontinuities, see this notebook
   • One can use higher time resolution data

For how to use this project as a python library, please see this page.

Installation

pip install ids-finder

Getting started

Import the package

TODOs

Science part

• Analysis
  • Contribution of discontinuities to the power spectrum
  • Check Datagap
  • Distribution of |B| over radius
  • Add error bar
  • More accurate way to obtain the properties of the discontinuities
• Identifaction
  • Ensemble forest?
  • Smoothing is important?
  • Check change point algorithm
