15+ Free and Paid Resources to Learn Python
Python is one of the most significant skills you’ll need not only in data science but in any position in the development/tech world. It’s used in a variety of fields and has a reputation for being easy to learn and simple to use. Here are 15+ free and paid... Read more
Scikit Optimize: Bayesian Hyperparameter Optimization in Python
So you want to optimize hyperparameters of your machine learning model and you are thinking whether Scikit Optimize is the right tool for you? You are in the right place. In this article I will: show you an example of using skopt on a real problem, evaluate this library based on... Read more
Implementing a Kernel Principal Component Analysis in Python
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
Web Scraping News Articles in Python
This article is the second of a series in which I will cover the whole process of developing a machine learning project. If you have not read the first one, I strongly encourage you to do it here. The project involves the creation of a real-time web application that gathers data from several newspapers... Read more
Local Regression in Python
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
Text Classification in Python
This article is the first of a series in which I will cover the whole process of developing a machine learning project. This one focuses on training a supervised learning text classification model in Python. The motivation behind writing these articles is the following: as a learning data scientist who has...

Discovering 135 Nights of Sleep with Data, Anomaly Detection, and Time Series
In this article, I look at data from 135 nights of sleep and use anomaly detection and time series data to understand the results. Three things are certain in life: death, taxes, and sleeping. Here, we’ll talk about the latest. Every night*, us humans, after a long day of... Read more
Swift Versus Python: Common Features, Strengths, and Weaknesses
There are many popular languages, but not all of them remain popular year after year. Nevertheless, some languages don’t lose their popularity and become even more widespread. We discuss the debate around Swift versus Python. For example, PYPL statistics for 2018... Read more
Timing the Same Algorithm in R, Python, and C++
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?
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
