What is Tabpy ?
TabPy (the Tableau Python Server) is an Analytics Extension implantation which expands Tableau's capabilities by allowing users to execute Python scripts and saved functions via Tableau's table calculations.
Benefits of TabPy :
Integrate Machine Leaning Algorithms
More Functionalities
Easily Maintained , Shared & Reused Models
Enhanced Developer & User Experience
Why TabPy : Use Case
Let's say I'm trying to identify criminal hotspots in city X using the City Police department showing calls reporting for various type of criminal activities in the past few years.
With this data . it is hard to identify patterns!
Density-based spatial of clustering of applications with noise or DBSCAN is a well - suited algorithm for this job.
TabPy Installation :
Steps to Install TabPy
- Install and update pip with the command python -m pip install - upgrade pip
- Install TabPy package with the command pip install tabpy
- Start TabPy on default setting with the command tabpy
- By default, your service runs on port.
Clustering With TabPy
Objective : To use an Air BnB dataset and cluster each zipcode based on their housing characteristics using several popular clustering algorithms with TabPy.
Perform the following functions :
- Import required Python libraries
- Scaling features with Standard Scaler
- Combine Scaled Features and handling null values
- Condition to check which algorithm to use
- Return clustering results as a list
