Context-sensitive ranking and choice in Python with PyTorch
kiudee, updated

NOTE
This library has recently been migrated from tensorflow to PyTorch. The 2.0 version marks a breaking change. Some of the previous functionality is now unavailable and some classes behave differently. You can use the latest 1.x release if you are looking for the tensorflow based estimators.
CS-Rank
CS-Rank is a Python package for context-sensitive ranking and choice algorithms.
We implement the following new object ranking/choice architectures:
- FATE (First aggregate then evaluate)
- FETA (First evaluate then aggregate)
In addition, we also implement these algorithms for choice functions:
- RankNetChoiceFunction
- GeneralizedLinearModel
- PairwiseSVMChoiceFunction
These are the state-of-the-art approaches implemented for the discrete choice setting:
- GeneralizedNestedLogitModel
- MixedLogitModel
- NestedLogitModel
- PairedCombinatorialLogit
- RankNetDiscreteChoiceFunction
- PairwiseSVMDiscreteChoiceFunction
Getting started
As a simple "Hello World!"-example we will try to learn the Pareto problem:
.. code-block:: python
import csrank as cs from csrank import ChoiceDatasetGenerator gen = ChoiceDatasetGenerator(dataset_type='pareto', n_objects=30, n_features=2) X_train, Y_train, X_test, Y_test = gen.get_single_train_test_split()
All our learning algorithms are implemented using the scikit-learn estimator
API. Fitting our FATENet architecture is as simple as calling the fit
method:
.. code-block:: python
fate = cs.FATEChoiceFunction() fate.fit(X_train, Y_train)
Predictions can then be obtained using:
.. code-block:: python
fate.predict(X_test)
Installation
The latest release version of CS-Rank can be installed from Github as follows::
pip install git+https://github.com/kiudee/cs-ranking.git
Another option is to clone the repository and install CS-Rank using::
python setup.py install
Dependencies
CS-Rank depends on PyTorch, skorch, NumPy, SciPy, matplotlib, scikit-learn, joblib and tqdm. For data processing and generation you will also need PyGMO, H5Py and pandas.

Bump joblib from 0.17.0 to 1.2.0
opened on 2022-09-30 19:49:56 by dependabot[bot]Bumps joblib from 0.17.0 to 1.2.0.
Changelog
Sourced from joblib's changelog.
Release 1.2.0
Fix a security issue where
eval(pre_dispatch)could potentially run arbitrary code. Now only basic numerics are supported. joblib/joblib#1327Make sure that joblib works even when multiprocessing is not available, for instance with Pyodide joblib/joblib#1256
Avoid unnecessary warnings when workers and main process delete the temporary memmap folder contents concurrently. joblib/joblib#1263
Fix memory alignment bug for pickles containing numpy arrays. This is especially important when loading the pickle with
mmap_mode != Noneas the resultingnumpy.memmapobject would not be able to correct the misalignment without performing a memory copy. This bug would cause invalid computation and segmentation faults with native code that would directly access the underlying data buffer of a numpy array, for instance C/C++/Cython code compiled with older GCC versions or some old OpenBLAS written in platform specific assembly. joblib/joblib#1254Vendor cloudpickle 2.2.0 which adds support for PyPy 3.8+.
Vendor loky 3.3.0 which fixes several bugs including:
robustly forcibly terminating worker processes in case of a crash (joblib/joblib#1269);
avoiding leaking worker processes in case of nested loky parallel calls;
reliability spawn the correct number of reusable workers.
Release 1.1.0
Fix byte order inconsistency issue during deserialization using joblib.load in cross-endian environment: the numpy arrays are now always loaded to use the system byte order, independently of the byte order of the system that serialized the pickle. joblib/joblib#1181
Fix joblib.Memory bug with the
ignoreparameter when the cached function is a decorated function.

CSRank 2.0.0-rc1 (13 April 2021)
Changes
-
The library has been migrated to pytorch. This is a breaking change. You will likely need to adapt to this new version if you have been using estimators from version 1.x.
-
The RankNet and CmpNet estimators are now trained with a loss that applies to the whole result (the general/discrete choice or ranking). They were previously trained on object pairs with different loss functions.
-
Behavior and default parameters of the estimators may differ from the previous versions. For example the default activation for CmpNet and RankNet is now SELU instead of ReLU.
