QUESTION

Implementation of Principal Component Analysis from Scratch Orients the Data Differently than scikit-learn

Asked 2021-Jun-11 at 14:09

Based on the guide Implementing PCA in Python, by Sebastian Raschka I am building the PCA algorithm from scratch for my research purpose. The class definition is:

When calculating an eigenvector you may change its sign and the solution will also be a valid one.

So any PCA axis can be reversed and the solution will be valid.

Nevertheless, you may wish to impose a positive correlation of a PCA axis with one of the original variables in the dataset, inverting the axis if needed.

How to apply KMeans to get the centroid using dataframe with multiple features

Asked 2020-Nov-28 at 10:37

I am following this detailed KMeans tutorial: https://github.com/python-engineer/MLfromscratch/blob/master/mlfromscratch/kmeans.py which uses dataset with 2 features.

But I have a dataframe with 5 features (columns), so instead of using the def euclidean_distance(x1, x2): function in the tutorial, I compute the euclidean distance as below.

...

ANSWER

Answered 2020-Nov-18 at 22:57

Reading the data and clustering it should not throw any errors, even when you increase the number of features in the dataset. In fact, you only get an error in that part of the code when you redefine the euclidean_distance function.

This asnwer addresses the actual error of the plotting function that you are getting.

Vulnerabilities

No vulnerabilities reported

Install MLfromscratch

This project has 2 dependencies. NOTE: Do note that, Only numpy is used for the implementations. Others help in the testing of code, and making it easy for us, instead of writing that too from scratch.
numpy for the maths implementation and writing the algorithms
Scikit-learn for the data generation and testing.
Matplotlib for the plotting.
Pandas for loading data.
