discontinuitypy 0.2.0

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 discontinuitypy

Getting started

Import the package

from discontinuitypy.utils.basic import *

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
• Features
  • Thickness in N direction
  • Use high resolution data for feature extraction
• Compare with other methods of identifying IDs
  • Verify with other methods of identifying IDs

Code part

• Optimization
  • dask for parallel computing instead of modin
  • JAX library for numpy optimization
  • shorten import time
• Refactor
  • process_candidates to exclude sat_state logics
  • renaming feature layer candidates
• Kedro
  • Modular pipelines

bugs

• STEREO B less than zero (after downsampling?)
