Detecting Knee and Elbow Points in Performance Curves Made Easy: Introducing the (Multi)Knee/Elbow Point Detection Library

Are you tired of struggling to identify the optimal trade-off between cost and performance in your performance curves? Say goodbye to the tedious process of manually analyzing performance curves, thanks to the groundbreaking (Multi)Knee/Elbow Point Detection Library! In this article, we will explore the features, functionalities, and implementation of this powerful library, designed to revolutionize knee/elbow point detection in performance curves.

Simplifying Knee/Elbow Point Detection

Estimating knee/elbow points in performance curves is a challenging task that often demands considerable time and effort. However, with the (Multi)Knee/Elbow Point Detection Library, this process is now easier than ever before. This library implements several well-known knee detection algorithms, including:

  1. Discrete Curvature
  2. DFDT
  3. Kneedle
  4. L-method
  5. Menger curvature

But that’s not all! The (Multi)Knee/Elbow Point Detection Library goes beyond traditional knee detection algorithms by introducing a revolutionary multi-knee/elbow point detection method. With the implementation of a recursive methodology, this library enables each algorithm to detect multi-knee and elbow points effortlessly. Notably, some algorithms natively support multi-knee detection, including Kneedle, Fusion, and Z-method.

Streamlining Knee Detection Tasks

To further enhance the knee detection process, the (Multi)Knee/Elbow Point Detection Library includes additional methods that facilitate knee detection tasks. As a preprocessing step, the library incorporates a custom RDP algorithm that effectively reduces a discrete set of points while maintaining minimal reconstruction error. As a post-processing step, the library offers several algorithms, including 1D dimensional clustering to merge closely located knee points and various filters to eliminate non-relevant knees. Additionally, the library incorporates knee ranking algorithms that leverage multiple criteria to assess the quality of knee points.

Easy Installation and Usage

Installing the (Multi)Knee/Elbow Point Detection Library is a breeze! Simply follow these steps:

  1. Set up a Python virtual environment:
    bash
    python3 -m venv venv
    source venv/bin/activate
    python -m pip install --upgrade pip

  2. Install the library:
    bash
    pip install .

Alternatively, if you prefer accessing the library via the PyPI repository, use the following command:
txt
pip install knee>=0.1

Once installed, running the library’s demos is as simple as executing the appropriate Python modules. Each demo corresponds to a specific knee detection algorithm. For example:
bash
python -m demos.curvature -i [trace]
python -m demos.dfdt -i [trace]
python -m demos.fusion -i [trace]
...
