Extremely simple and fast extreme multi-class and multi-label classifiers.

Overview

napkinXC

C++ build Python build Documentation Status PyPI version

napkinXC is an extremely simple and fast library for extreme multi-class and multi-label classification, that focus of implementing various methods for Probabilistic Label Trees. It allows training a classifier for very large datasets in just a few lines of code with minimal resources.

Right now, napkinXC implements the following features both in Python and C++:

  • Probabilistic Label Trees (PLTs) and Hierarchical softmax (HSM),
  • different type of inference methods (top-k, above given threshold, etc.),
  • fast prediction with labels weight, e.g., propensity scores,
  • efficient online F-measure optimization (OFO) procedure,
  • different tree building methods, including hierarchical k-means clustering method,
  • training of tree node
  • support for custom tree structures, and node weights,
  • helpers to download and load data from XML Repository,
  • helpers to measure performance (precisio[email protected], [email protected], [email protected], propensity-scored [email protected], and more).

Please note that this library is still under development and also serves as a base for experiments. API may not be compatible between releases and some of the experimental features may not be documented. Do not hesitate to open an issue in case of a question or problem!

The napkinXC is distributed under MIT license. All contributions to the project are welcome!

Python Quick Start and Documentation

Python (3.5+) version of napkinXC can be easily installed from PyPy repository on Linux and MacOS, it requires modern C++17 compiler, CMake and Git installed:

pip install napkinxc

or the latest master version directly from the GitHub repository (not recommended):

pip install git+https://github.com/mwydmuch/napkinXC.git

Minimal example of usage:

from napkinxc.datasets import load_dataset
from napkinxc.models import PLT
from napkinxc.measures import precision_at_k

X_train, Y_train = load_dataset("eurlex-4k", "train")
X_test, Y_test = load_dataset("eurlex-4k", "test")
plt = PLT("eurlex-model")
plt.fit(X_train, Y_train)
Y_pred = plt.predict(X_test, top_k=1)
print(precision_at_k(Y_test, Y_pred, k=1)) 

More examples can be found under python/examples directory. napkinXC's documentation is available at https://napkinxc.readthedocs.io.

Executable

napkinXC can also be used as executable to train and evaluate models using a data in LIBSVM format. See documentation for more details.

References and acknowledgments

This library implements methods from following papers (see experiments directory for scripts to replicate the results):

Another implementation of PLT model is available in extremeText library, that implements approach described in this NeurIPS paper.

  • OOM/SegFault issues?

    OOM/SegFault issues?

    PLTs train extremely quickly using this implementation which is fantastic to see. However, I have run into a few issues when training on larger datasets:

    • There is no batching method by default, which then requires very large matrices to be held in matrices in order to train the model. I assume the way to avoid this in memory issue is FitOnFile
    • Even if the training data fits comfortably in memory, at larger sizes such as >1 million training data points with >10k labels, the Python kernel crashes which I assume is due to an OOM or s error on the C++ side. It feels like there must be a memory leak somewhere, as the actual trees themselves never get that large, and I assume internally that the model trains in batches as outlined in the paper

    feature dimension mismatch between train and test data

    Hi,

    There seems to be a bug in the data loading process.

    For example:

    from napkinxc.datasets import load_dataset
    trn_X, _ = load_dataset('wiki10-31k', 'train')
    tst_X, _ = load_dataset('wiki10-31k', 'test')
    print('# of features of training data', trn_X.shape[1])
    print('# of features of test data', tst_X.shape[1])
    

    gives:

    # of features of training data 101938
    # of features of test data 101937
    

    Cheers, Han

    Hi,

    The following snippet gives segmentation fault on my machine:

    from napkinxc.models import PLT
    from napkinxc.datasets import load_dataset
    
    trn_X, trn_Y = load_dataset('eurlex-4k', "train", verbose=1)

    Support for custom tree (tree_structure in python interface)

    Hi,

    Thanks for writing this software, which is very useful!

    I'm currently experimenting with the effect of label trees and wish to load trees from file.

    Is it possible to pass a string to thetree_structure parameter in models.PLT class, so that a custom tree can be loaded? It seems like the current Python interface does not support it.

    If possible, I can make a pull request, and it would be nice if some instructions can be given, e.g., where and what to modify.

    Hi,

    During kmeans initialization, the randomly generated row index can produce segfault.

  • Seg Fault Fix

    Seg Fault Fix

    Hello! While trying to do OFO using the python interface I was running into some segmentation faults happening at random times while doing Macro OFO. I went into the C++ code and I think I found the culprit, which was a pre-increment counter being used instead of the counter itself, which would result in the code trying to access memory outside the array's limits. When I tried running it again after making this change, I stopped getting seg faults and the OFO score actually improved. Disclaimer: I am quite rusty with C++ so please double check.

    pickling models

    Hi,

    I'm trying to use napkinXC under ray, which relies pickle for data serialization.

    It seems that napkinXC models cannot be pickled.

    For instance,

    import pickle
    from napkinxc.models import PLT
    
    model = PLT('/tmp/something/')
    pickle.dump(model, open('/tmp/some-pickle.pkl', 'wb'))
    

    gives:

    TypeError: cannot pickle 'napkinxc._napkinxc.CPPModel' object.
    

    Is there any workaround or any plan to support pickling for this issue?
