In simple English

Sensor readings change every second, but machine learning models cannot read raw squiggles directly. This tool turns those squiggles into plain numbers that a computer program can study. It calculates sixty different statistical facts from your data files. You need to know some Python code to run it. It costs nothing to use, and your data stays on your own computer.

What it is

Time Series Feature Extraction Library is an open-source Python library that calculates statistical, temporal, spectral, and fractal features from time series data. It helps prepare sensor logs, financial tickers, and medical recordings for classification and regression tasks.

What it is good for

This is good for solo builders who collect data from sensors, smart meters, or medical devices and want to train a machine learning model on that data without writing math formulas from scratch.

Good
  • Extracts over sixty features across four different mathematical domains automatically.
  • Estimates how long the calculation will take before running on large datasets.
  • Includes sample datasets so you can test feature extraction immediately.
Watch for
  • Requires writing and running Python code in a command-line environment.
  • Some complex fractal and spectral calculations take noticeable time on large files.
  • Documentation assumes prior knowledge of signal processing concepts.
Replaces

Writing custom math functions in NumPy or SciPy to calculate signal variance, entropy, and frequency spectra by hand.

Works well with

Used together with scikit-learn for training classification models on the extracted features.
