Green Magic - Python Library
Green Magic is a library containing class models allowing users to train machine learning models as well as visualize cannabis strain data. It has functionality for encoding raw cannabis strain data into features usefull for visualization and cluster analysis. It contains implementations for model evaluation and methods for data exploration.
Key features of the Library:
Data cleaning
Seemless dataset creation
Extendable feature extraction system
Usage of the Somoclu library [1] as the backend, which allows for ‘fast execution of Self-Organizing Maps by parallelization: OpenMP and CUDA are supported’.
Visualization of maps
Kmeans and Affinity-propagation based clustering
Formatted print of statistics and distributions
Usage
A simple example is below.
from green_magic import WeedMaster
from green_magic.clustering import ClusteringFactory, DistroReporter, get_model_quality_reporter
all_vars = ['type', 'effects', 'medical', 'negatives', 'flavors']
active_vars = ['type', 'effects', 'medical', 'negatives', 'flavors']
wd = 'pd'
wm = WeedMaster()
dt = wm.create_weedataset(dt_path, wd)
dt.use_variables(active_vars)
dt.clean()
vectors = wm.get_feature_vectors(dt)
print(dt)
wm.save_dataset(wd)
som = wm.map_manager.get_som('toroid.rectangular.30.30.pca')
wm.map_manager.show_mmap(som)
clf = ClusteringFactory(wm)
cls = clf.create_clusters(som, 'kmeans', nb_clusters=10, vars=all_vars, ngrams=1)
print(cls)
cls.print_map()
r = DistroReporter()
r.print_distros(cls0, 'type', prec=3)
qr = get_model_quality_reporter(wm, wd)
print(qr.measure(cls, metric='silhouette'))
print(qr.measure(cls, metric='cali-hara'))
Installation
The code is available on PyPI, hence it can be installed by
$ pip install green_magic
