Naive Bayes: A Baseline Model for Machine Learning Classification Performance

By Asel Mendis, KDnuggets on May 7, 2019 in Algorithms, Data Science, Machine Learning, Naive Bayes, Python, scikit-learn, Statistics
We can use Pandas to conduct Bayes Theorem and Scikitlearn to implement the Naive Bayes Algorithm. We take a step by step approach to understand Bayes and implementing the different options in Scikitlearn.
Data Visualization in Python: Matplotlib vs Seaborn

By Asel Mendis, KDnuggets on April 19, 2019 in Advice, Data Visualization, Matplotlib, Python, Seaborn
Seaborn and Matplotlib are two of Python's most powerful visualization libraries. Seaborn uses fewer syntax and has stunning default themes and Matplotlib is more easily customizable through accessing the classes.
Which Face is Real?

By Asel Mendis, KDnuggets on April 2, 2019 in Deep Learning, GANs, Generative Adversarial Network, Neural Networks, NVIDIA, Python
Which Face Is Real? was developed based on Generative Adversarial Networks as a web application in which users can select which image they believe is a true person and which was synthetically generated. The person in the synthetically generated photo does not exist.

By Asel Mendis, KDnuggets on March 25, 2019 in Data Visualization, ggplot2, Matplotlib, Python, Python vs R, R, Seaborn
This article demonstrates creating similar plots in R and Python using two of the most prominent data visualization packages on the market, namely ggplot2 and Seaborn.
Running R and Python in Jupyter

By Asel Mendis, KDnuggets on February 19, 2019 in IPython, Jupyter, Python, R
The Jupyter Project began in 2014 for interactive and scientific computing. Fast forward 5 years and now Jupyter is one of the most widely adopted Data Science IDE's on the market and gives the user access to Python and R
Logistic Regression: A Concise Technical Overview

By Asel Mendis, KDnuggets on January 23, 2019 in Logistic Regression, Machine Learning
Logistic Regression is a Regression technique that is used when we have a categorical outcome (2 or more categories). Logistic Regression is one of the most easily interpretable classification techniques in a Data Scientist’s portfolio.
