Web Application with Data Centric Approach to Ship Powering Prediction using Deep Learning

Prerequisite

• Interpreter ver.: python 3.6.15
• Container ver.: Docker 20.10.10
• Application ver.: v1.0
• Dependencies: As per listed in requirements.txt

Introduction

This web application is developed based on the joint work between the Marine Technology Centre , Universiti Teknologi Malaysia (UTM) and the Hiekata Laboratory, University of Tokyo (UTokyo) under the UTM research project "Predictive Model for Ship Design and Configuration Using Machine Learning : Model Development and Validation", project number: Q.J130000.3851.19J88.

The details of the ship powering prediction modelling is first described in the research paper presented in the International Conference on Design and Concurrent Engineering 2021 & Manufacturing System Conference 2021

Getting started

1. Clone the repo by running this command in the terminal:

git clone https://github.com/jtkhair/aiship_webapp

2. Make sure to run the command git pull (if you already cloned this repo). In the cloned repo directory, run this command in the terminal:

git pull https://github.com/jtkhair/aiship_webapp

3. Build docker image by running below commands in the terminal (make sure docker is running):

cd aiship_webapp
docker build -t aishipwebapp:1.0 .

4. Run the docker container by running below command in the terminal:

docker run -d --name aishipwebapp -p 80:80 aishipwebapp:1.0

5. Go to the link http://0.0.0.0:80 or http://localhost:80 to use the web app

6. Input dataset *.csv file and click submit to perform the prediction. Note that the *.csv file must follow the set schema: (['ID', 'LWL', 'B', 'T', 'L/B', 'B/T', 'Disp', 'CB', 'Vs'. 'Fn', 'P']) and example data file as in the src/data directory
