okay so when I use the following code, what exactly does that "clf" part mean? is that a variable? I know that's a classifier but is classifier a function in python or it's just a variable named that way or what exactly? I am new to python and programming well. thanks already!
from sklearn.naive_bayes import GaussianNB
clf = GaussianNB()
From the docs:
[GNB] can perform online updates to model parameters via partial_fit method
Example:
>>> import numpy as np
>>> X = np.array([[-1, -1], [-2, -1], [-3, -2], [1, 1], [2, 1], [3, 2]])
>>> Y = np.array([1, 1, 1, 2, 2, 2])
>>> from sklearn.naive_bayes import GaussianNB
>>> clf = GaussianNB()
>>> clf.fit(X, Y)
GaussianNB(priors=None, var_smoothing=1e-09)
>>> print(clf.predict([[-0.8, -1]]))
[1]
>>> clf_pf = GaussianNB()
>>> clf_pf.partial_fit(X, Y, np.unique(Y))
GaussianNB(priors=None, var_smoothing=1e-09)
>>> print(clf_pf.predict([[-0.8, -1]]))

What is a classifier, one may ask? According to Wikipedia, a classifier is
an algorithm that implements classification, especially in a concrete implementation, is known as a classifier. The term "classifier" sometimes also refers to the mathematical function, implemented by a classification algorithm, that maps input data to a category.
