Right after the release of the 2nd Generation Pokemon in Pokemon Go, I’ve got my scanners working and collecting Pokemon spawn data. Over the last 24 hours (minus a few hours of downtime), I’ve collected 182,898 individual spawn data for Gen II Pokemon.

As I begin working on the data, here is a quick glimpse of how rare different Pokemon are.

Finding Dratini Nest w DBSCAN


My previous post documented the method I’ve used to rank the various Pokemon Nests. For many beginners, the whole process seemed to be a little lengthy. In this post, I’ll be showing a much faster way to search for the nests amidst the noise using another clustering algorithm, DBSCAN. I’ll be using the Dratini Dataset for this process.

Step-by-step Pokemon Go Clustering


Last Sunday I’ve the honour of introducing basic concepts of data mining to a group of enthusiast who signed up for the talk on my blog. During the talk, they were introduced to how I collect the data, how the data were processed and how the data were data mined. They also have a first-hand experience of analysing the nest through the clustering technique. In this post, I’ll be walking through the steps to find and rank the Pokemon nests. The data used for the analysis can be downloaded in this post, so make sure you follow along!

Data Mining Talk & Release of Dataset


In my previous blog post, I’ve mentioned that I’ll be releasing the Pokemon spawn data used for the analysis as well as to provide more details to the upcoming data mining w/ Pokemon talk.

And now… Here’s the information about the upcoming data mining talk!

Data Mining Pokemon Nest (Part 3)

First of all, thank you for your support for the previous posts. If you’ve missed the post about ultra-rare Pokemon, it’s here. If you’ve missed the one on the starter Pokemon, it’s here . This post will cover the remaining Pokemon nests in Singapore, featuring Dratini’s nest for players to farm up their Dragonite.

With this post, most of the Pokemon nest will have been revealed with the exception of Gastly, Hitmonlee, Hitmonchan & Likitung. The reason for leaving that 4 Pokemon out is that their appearance rates belong to the Ultra-rare group. To view the Pokemon nest plotted on Google map, scroll to the bottom of the entire post.
