Personal Mini-Projects

This contains my mini-projects to solve real-world problems using data science methodology.

Implementing Machine Learning Model to Predict and Select Loan

This notebook demonstrates an acitivity to develop a machine learning model for solving classification problem, that may serves as decision support system. The model will be implemented to build a simple algorithm that decide which loan should we invested on, this is to demonstrate utilizing the model as some sort of informed-decision. The algorithm involves some optimizing technique

Linear Regression Model of Jabodetabek House Price and its Implementation

Analyzing Jabodetabek house price by utilizing information from the internet. The data itself will be retrieved from one of Indonesian house listing website. Linear model will be developed as a reasonable basis to estimate Jabodetabek House Price based on several parameters regarding the characteristic of the house. The challenge of linear model is to deal with heteroscedastic nature of the data. Usefulness of the linear regression model will be demonstrated to solve a simple fictitious problem to maximize profit of housing project.
