Functional Transformation
I am a undergraduate student who is currently immersed in the process of learning. Although I am not an expert, I have a strong passion for acquiring knowledge and sharing it with others. My aim is to continuously expand my understanding of machine learning while providing valuable insights and resources to fellow learners.
In this journey of exploration, I strive to create a supportive community where we can learn and grow together. If you have any feedback, suggestions, or simply want to connect and exchange ideas, I would be more than happy to engage in meaningful discussions.
Why do we use Functional Transformation:- To make the distribution of the data normal
The normal distribution can be found using QQ plot (import scipy.stats as stats)
This is a normal distribution
Mathematical transform in feature transformation
Functional Transformer
log transform (apply to right-skewed data)
Recripocal transform
square transform ( apply to left skewed data)
power Transformer (Mostly used for transformation)
Box-Cox transform
yeo-johnson transform
