🌳 A Python-inspired implementation of the Optimum-Path Forest classifier.

Overview

OPFython: A Python-Inspired Optimum-Path Forest Classifier

Latest release DOI Build status Open issues License

Welcome to OPFython.

Note that this implementation relies purely on the standard LibOPF. Therefore, if one uses our package, please also cite the original LibOPF authors.

Have you ever wanted to classify data into labels? If yes, OPFython is for you! This package is an innovative way of dealing with an optimum-path forest classifier. From bottom to top, from samples and datasets to the actual classifier, we will foster all research related to this new trend.

Use OPFython if you need a library or wish to:

  • Create your datasets;
  • Design or use pre-loaded state-of-art classifiers;
  • Mix-and-match different strategies to solve your problem;
  • Because it is cool to classify things.

Read the docs at opfython.readthedocs.io.

OPFython is compatible with: Python 3.6+.


Package guidelines

  1. The very first information you need is in the very next section.
  2. Installing is also easy if you wish to read the code and bump yourself into, follow along.
  3. Note that there might be some additional steps in order to use our solutions.
  4. If there is a problem, please do not hesitate. Call us.

Datasets

In search for datasets? We have some already pre-loaded into OPF file format. Just check them out at our website!


Getting started: 60 seconds with OPFython

First of all. We have examples. Yes, they are commented. Just browse to examples/, chose your subpackage, and follow the example. We have high-level examples for most tasks we could think.

Alternatively, if you wish to learn even more, please take a minute:

OPFython is based on the following structure, and you should pay attention to its tree:

- opfython
    - core
        - heap
        - node
        - opf
        - subgraph
    - math
        - distance
        - general
        - random
    - models
        - knn_supervised
        - semi_supervised
        - supervised
        - unsupervised
    - stream
        - loader
        - parser
        - splitter
    - subgraphs
        - knn
    - utils
        - constants
        - converter
        - decorator
        - exception
        - logging

Core

Core is the core. Essentially, it is the parent of everything. You should find parent classes defining the basis of our structure. They should provide variables and methods that will help to construct other modules.

Math

Just because we are computing stuff, it does not means that we do not need math. Math is the mathematical package, containing low-level math implementations. From random numbers to distributions generation, you can find your needs in this module.

Models

Each machine learning OPF-based technique is defined in this package. From Supervised OPF to Unsupervised OPF, you can use whatever suits your needs.

Stream

Every pipeline has its first step, right? The stream package serves as primary methods to load data, parse it into feasible arrays, and split them into the desired sets (training, evaluation, testing).

Subgraphs

As each type of OPF classifier might need a particular subgraph, we opted to define a unique package to hold them all. The subgraph's package is in charge of implementing some of its varities, such as the k-nearest neighbour (KNN) subgraph.

Utils

This is a utility package. Common things shared across the application should be implemented here. It is better to implement once and use it as you wish than re-implementing the same thing over and over again.


Installation

We believe that everything has to be easy. Not tricky or daunting, OPFython will be the one-to-go package that you will need, from the very first installation to the daily-tasks implementing needs. If you may just run the following under your most preferred Python environment (raw, conda, virtualenv, whatever):

pip install opfython

Alternatively, if you prefer to install the bleeding-edge version, please clone this repository and use:

pip install -e .

Environment configuration

Note that sometimes, there is a need for additional implementation. If needed, from here you will be the one to know all of its details.

Ubuntu

No specific additional commands needed.

Windows

No specific additional commands needed.

MacOS

No specific additional commands needed.


Support

We know that we do our best, but it is inevitable to acknowledge that we make mistakes. If you ever need to report a bug, report a problem, talk to us, please do so! We will be available at our bests at this repository or [email protected].

  • Question about computing input indicators importance

    Question about computing input indicators importance

    Hello gugarosa! I have some questions when using the OPF algorithm for slope stability classification project. Can the OPF algorithm be implemented to calculate the importance of each input index? Like the RandomForest algorithm, it is possible to calculate its "Gini importance" through "sklearn".

    If so, please let me know how to calculate it.

    Thank you very much and have a nice life!

    Description

    [Description of the issue] I have a question for the authors about the OPF algorithm. After using the OPF algorithm for classification, I need to evaluate the algorithm, then I choose to plot the ROC curve to evaluate the performance of the classifier, I use the "fpr, tpr, thresholds = metrics.roc_curve(y_true, y_score)" in the sklearn library to calculate fpr and tpr. " to calculate fpr and tpr, now I know "y_true", how to calculate this "y_score"? I checked the user guide of the sklearn library and it gives the following explanation: In the binary case, it corresponds to an array of shape (n_samples,). Both probability estimates and non-thresholded decision values can be provided. with the greater label. So how to calculate this "y_score" in the OPF algorithm? I plotted the ROC with the predicted label as the "y_score", and the resulting graph has only one inflection point.

    [REG] The labels should start from 1, which is not that obvious

    I would like to thank you for providing the source code

    I have a comment, the labels should start from 1 in order for the code to work, which might not be obvious for some. I just like to bring this to your attention as many datasets have the label of 0.

    [NEW]

    I would really like it if there was a probability measure of the decision similar to the "predict_proba_" method of scikit-learn models. This would enable model calibration and also help in calculating threshold based metrics (personally I have to get the ROC-AuC score)

    I'm not familiar with the nooks and crannies of OPFython but my search yielded no results for features which may enable me to get probability scores instead of labels.

      These frameworks are no longer be automatically injected into themes from Sphinx 6.0. If you develop a theme or extension that uses the jQuery, $, or $u global objects, you need to update your JavaScript to modern standards, or use the mitigation below.

      The first option is to use the sphinxcontrib.jquery_ extension, which has been developed by the Sphinx team and contributors. To use this, add sphinxcontrib.jquery to the extensions list in conf.py, or call app.setup_extension("sphinxcontrib.jquery") if you develop a Sphinx theme or extension.

      The second option is to manually ensure that the frameworks are present. To re-add jQuery and underscore.js, you will need to copy jquery.js and underscore.js from the Sphinx repository_ to your static directory, and add the following to your layout.html:

    Description

    Welcome to v1.0.11 release.

    In this release, we have fixed the labels indexing, where it should start from 0 instead of 1.

    Additionally, we have added the Numba package to help the distance calculation. From its usage, we observed a decrease of more than 50% in both training and testing times.

    Changelog

    Description

    Welcome to v1.0.7 release.

    In this release, we have added several distance metrics and their respective tests. Additionally, we have speed up their computation by 30% ~ 40%, which we hope that will ease the training of larger datasets.

    Changelog

    Description

    Welcome to v1.0.4 release.

    As always, there were some nasty bugs that we have fixed in an attempt to improve your overall experience. We have added a method for pre-computing distance for speeding up the training process, as well as a method for returning the clusters assignments from new predictions.

    With that in mind, it will be easier to check whether something is not working as it should.
