The main idea is tonormalize/standardizei.e.μ = 0andσ = 1yourfeatures/variables/columnsofX,individually,beforeapplying any machine learning model. Thus,StandardScaler()willnormalize the featuresi.e. each column of X,INDIVIDUALLYso that each column/feature/variable will haveμ = 0andσ = 1. ...
There is also the function unit_vector() to normalize vectors in the popular transformations module by Christoph Gohlke: import transformations as trafo import numpy as np data = np.array([[1.0, 1.0, 0.0], [1.0, 1.0, 1.0], [1.0, 2.0, 3.0]]) print(trafo.unit_vector(data, axis=1)) ...
2 - Data acquisition from Newsapi.org Well, this looks like something very handy. This avoids the tedious data scrapping that you would perform on each site separately. Getting the latest news for a specific source like Techcrunch is as simple as sending a get request to this address:https:...

So, how to rectify the dominant class and still maintain the separateness of the distributions? You can normalize it by setting density=True and stacked=True. By doing this the total area under each distribution becomes 1. # Normalize kwargs = dict(alpha=0.5, bins=100, density=True, stacke...
