You must have heard this phrase if you have ever encountered a senior Kaggle data scientist or machine learning engineer. The fact is that this is a true phrase. In a real-world data science project, data preprocessing is one of the most important things, and it is one of the common fac...
Around 90% of the time spent on data analytics, data visualization, and machine learning projects is dedicated to performing data preprocessing. This book covers the following exciting features: Use Python to perform analytics functions on your data Understand the role of databases and how to ...
data_standardized = preprocessing.scale(input_data) print "\nMean = ", data_standardized.mean(axis = 0) print "Std deviation = ", data_standardized.std(axis = 0) 现在在终端上运行以下命令 - $ python prefoo.py 您可以观察以下输出 - Mean = [ 5.55111512e-17 -3.70074342e-17 0.00000000e+00...
