How to Build A Machine Learning Web App Step-by-Step

The world is gradually changing, and the demand for data science and data-related jobs has increased. Most aspiring data scientists know this fact and want to become a part of this field. As a result, they attempt to build their machine learning applications development skills. Soon after, they realize that machine learning is concerned chiefly with modeling and algorithms.

In our modern-day society, it’s crucial that data scientists can design machine learning web apps for startups and large organizations. Many of these organizations want to develop machine learning web apps to generate new data points and predictions for your production. They want models that can predict specific outcomes and solve particular problems.

Are you a data scientist who wants to learn how to build a machine learning app but doesn’t know how to go about it? You’re at the right place. This piece will teach you the step-by-step process of building a web app. Let’s begin.

Step-By-Step Procedure Machine Learning Application Development

Design Your Setup

Before you can start building the machine learning application, you need to choose an Integrated Development Environment that you will work in. While you’re free to use an IDE, we will select a Python IDE to describe the development process to you. Famous examples of Python IDE that you can use include; Atom, Eclipse, or Visual Studio Code. Take note that you’ll be unable to use Jupyter to create a machine learning application. Well, Jupyter is designed for data analysis and isn’t a feasible alternative to run a web server.

When you have finally set up your IDE, the next step is to install the following libraries; Flask, Nltk, and Pandas.

Build the App

When building the machine learning app, you have to keep in mind that it will have two parts – the front-end and back-end. The first thing to do is create a new folder for the new web app you are developing. This new folder will help you organize your work into sections. You’ll find the following files under the newly created folder;

  • .gcloudignore
  • .app. YAML
  • requirements.txt

The file is where you input the machine learning code for your web app.

Front-end Development

The front end of your web app will be developed using HTML. While it’s not the focus of this article, we must inform you. This way, you’re aware of everything it takes to develop your web app fully. You can design a simple HTML template and CSS style sheet to create an input form here. You don’t need too much programming knowledge to successfully design HTML for simple applications.

Back-end Development

The back-end of your web application is where all the machine learning goes. The back-end can be built from scratch using the Flash framework. As mentioned earlier, Flash is one of the libraries in Python and can be successfully imported just like others. Depending on the skill level of the back-end developer, you can incorporate as many features as possible into your web app. However, the front-end is designed only to collect six main components: age, sex, BMI, region, children, region, and smoker.

Testing and Deploying the Web App

After the machine learning application has successfully been created, it needs to be tested to run correctly. Test every part of the web app, including the input form you have made. Then, observe how the machine learning programming fares under different conditions. After the app has been successfully tested, it needs to be deployed and integrated to begin using it.


And that’s all on machine learning applications development. If you managed to make it to the end, that means that you have successfully designed and deployed your web app.

Depending on what you intend to use your app for, you can apply the information in this article to various degrees. You can begin to look forward to all the benefits these apps will offer you.
