Implementing a Kernel Principal Component Analysis in Python

ModelingPythonTools & Languagesprincipal component analysisposted by ODSC Community November 26, 2019

In this article, we discuss implementing a kernel Principal Component Analysis in Python, with a few examples.  Many machine learning algorithms make assumptions about the linear separability of the input data. The perceptron even requires perfectly linearly separable training data to converge. Other algorithms that we have covered so... Read more

I love data visualization make-overs (like this one I wrote a few months ago), but sometimes the tone can be too negative (like this one I wrote a few months ago). Sarah Leo, a data journalist at The Economist, has found the perfect solution: re-making your own visualizations. Here’s her tweet.... Read more

Timing the Same Algorithm in R, Python, and C++

PythonRTools & LanguagesC++PythonRposted by John Mount September 23, 2019

While developing the RcppDynProg R package I took a little extra time to port the core algorithm from C++ to both R and Python. This means I can time the exact same algorithm implemented nearly identically in each of these three languages. So I can extract some comparative “apples to apples” timings. Please read on for a...

How Do You Do an Arithmetic Expression Using Python?

PythonTools & LanguagesArithmetic Expressionposted by Divyesh Dharaiya September 17, 2019

Expressions are portrayals of significant value. They are unique in relation to explanation in the way that announcements work on something while expressions are portrayal of significant value. For instance any string is likewise an expressions since it speaks to the estimation of the string also. Python has some... Read more
