Usage

Define your own objective function for optimization !

from sklearn.metrics import log_loss
# define your own objective function, make sure the function receives four parameters,
#  fit your model and return the objective value ! 
def objective_function_topass(model,X_train, y_train, X_valid, y_valid):      
    model.fit(X_train,y_train)  
    P=log_loss(y_valid,model.predict_proba(X_valid))
    return P
    
# import an algorithm !  
from zoofs import ParticleSwarmOptimization
# create object of algorithm
algo_object=ParticleSwarmOptimization(objective_function_topass,n_iteration=20,
                                       population_size=20,minimize=True)
import lightgbm as lgb
lgb_model = lgb.LGBMClassifier()                                       
# fit the algorithm
algo_object.fit(lgb_model,X_train, y_train, X_valid, y_valid,verbose=True)
#plot your results
algo_object.plot_history()

Suggestions for Usage

As available algorithms are wrapper algos. It is better to use ml models that build quicker, e.g lightgbm, catboost.
Take sufficient amount for 'population_size' , as this will determine the extent of exploration and exploitation of the algo.
Ensure that your ml model has its hyperparamters optimized before passing it to zoofs algos.

Looking for integrated Harris Haw Optimization in the zoofs

Additional context Harris Haw Optimization (HHO) is a novel meta-heuristic optimization algorithm released in 2019 with an increasing of applied research papers. It would be great if the team can add the HHO to the zoofs which will be potential for further testing and make the zoofs more popular.

Hi, Thanks for the great repo. I would like to know whether we can get the ranking of the selected features after using one of your algorithm (ex: particle swarm optimization)

Hyperparameter optimization for algorithms in zoofs

Hi Jaswinder,

Would you consider to add the function like GridSearch for hyper-parameter optimization of the algorithm, such as GWO, in the zoofs? This library, PySwarm (https://github.com/tisimst/pyswarm) for instance, they provide a GridSearch to find the best combination of the parameters c, w1, w2.

For now, I have to do the trial and error to test which ranges of parameters in the GWO (population, iteration, method) deliver the best result for my dataset.

Many thanks, Thang

Disabling verbose still prints logs

Setting verbose=False still produces output at every iteration. This is problematic since the JSON file can get very large when the fit function runs for prolonged period of time.

Snyk has created this PR to fix one or more vulnerable packages in the `pip` dependencies of this project.

Changes included in this PR

Changes to the following files to upgrade the vulnerable dependencies to a fixed version:

docs/requirement.txt

⚠️ Warning

mkdocs-material 8.0.1 requires pygments, which is not installed. mkdocs-material 8.0.1 requires mkdocs-material-extensions, which is not installed. mkdocs-material 8.0.1 requires markdown, which is not installed. mkdocs-material 8.0.1 requires pymdown-extensions, which is not installed. mkdocs-material 8.0.1 requires mkdocs, which is not installed. jupyter-nbextensions-configurator 0.6.1 requires notebook, which is not installed. jupyter-contrib-nbextensions 0.7.0 requires nbconvert, which is not installed. jupyter-contrib-nbextensions 0.7.0 requires notebook, which is not installed. jupyter-contrib-core 0.4.2 requires notebook, which is not installed.

(*) Note that the real score may have changed since the PR was raised.

Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the affected dependencies could be upgraded.

Speed-up suggestions

It doesn't accept numpy arrays and so numba is out of question. Any suggestions to improve speed? When you have 100+ feature columns it takes atleast 2 weeks running 24/7
