Writing code is a slow process especially when you are first learning data science. What if you could speed it up? You can and this is how. In this free R-tip, I share a real case study where I made the working R code for my data analysis in under 30 ...

Introduction Many of us in the U.S. have been surprised by the indifference many in less developed countries have shown about the Ukraine war. There has been much talk lately about how the “Global South” is feeling slighted by the rich countries ...

Segmentation is a process of partitioning space into smaller segments. For example, imagine looking at your family photo and trying to distinct individual people. Similarly, we can look at a satellite image (in RGB colors) with the goal of delin...

A riddle from The Riddler on how many different numbers one could at most produce from six initial values and the four basic operations. In other words, how many values could the terms in a∅(b∅{c∅[d∅(e∅f)]}) could take? (With each ∅ being one of the four operations ...

I’m not a big movie person. Nonetheless I have a media library with quite a few films in and I wondered how many “films to see before you die”-type movies I had in the collection, and how many were missing. I used R to find the answers. I’...

Introduction Recently, I stepped into the AWS ecosystem to learn and explore its capabilities. I’m documenting my experiences in these series of posts. Hopefully, they will serve as a reference point to me in future or for anyone else following this p...

Back in 2016, I did a post on {ggplot2} text annotations because it was a tad more challenging to do some of the things in that post back in the day. Since I’ve been moving back and forth between R and Observable (and JavaScript in general), I decided to recreate ...

Word clouds are a visual representation of text data where words are arranged in a cluster, with the size of each word reflecting its frequency or importance in the data set. Word clouds are a great way of displaying the most prominent topics or keywords in free text data obtained ...

Introduction As data science continues to be a sought-after field, creating a reliable and accurate model is essential. While there are various machine learning algorithms available, the process of selecting the correct algorithm can be complex....
