Hi! On this article I will cover the basic of creating your own classification model with Python. I will try to explain and demonstrate to you step-by-step from preparing your data, training your model, optimising the model, and how to save it for later use. This article is the second part of a mini-series I have been working on, if you haven’t read my previous article on ‘Multi-Linear Regression Using Python’ be sure to check it out.

You can try to follow along using the notebook here, good luck and have fun!

Hi! It’s been a while since the last time I write an article here. In today’s article I want to talk about how to do a multi-linear regression analysis using Python. Most of the writing in this article is directly taken from my assignment at Telkom Digital Talent Incubator 2020 a few weeks ago. You can check the notebook here and try to follow along. So without further ado, let’s start!


Regression analysis itself is a tool for building statistical models that characterize relationships among a dependent variable and one or more independent variables. Simple Linear Regression refers to the…

‘Machine Learning’ atau ‘Pembelajaran Mesin’ dalam Bahasa Indonesia mungkin sudah cukup sering kita dengar baik di dunia akademis maupun bisnis. Pembicaraan terkait Machine Learning (atau biasa disingkat ML) biasanya juga didampingi dengan istilah populer lain seperti Big Data, Artificial Intelligence, hingga Deep Learning. Nyatanya memang semua hal itu berkaitan dan saling terhubung satu sama lain.

Pada artikel hari ini saya akan mencoba sedikit menjelaskan tentang Machine Learning dan mencoba memberikan contoh penerapan-nya yang mungkin pernah kita rasakan di kehidupan kita sendiri.

Moneyball (2011)

Today I am going to write about the movie Moneyball (2011). As a baseball fans, Moneyball is definitely one of my favorite movie all time. The movie told the story behind the unorthodox success of the 2002 Oakland Athletic (also known as Oakland A’s) managed by Billy Beane (a former baseball player and scout) and his assistant Peter Brand (a Yale’s Economics graduate).

Moneyball, what is it?

To start, let’s first talk about the term ‘moneyball’. What does it actually means? In general the understanding of moneyball is the approach to get a team as many win as possible while spending as little money…
