End To End Guide For Machine Learning Projects


Let’s imagine you are attempting to work on a machine learning project. This article will provide you with the step to step guide on the process that you can follow to implement a successful project.



By Farhad Malik, Editor of FinTechExplained

It’s very hard to find a succinct article providing an end-to-end guide to implement a machine learning project. We find many informative articles online providing an in-depth coverage of how we need to implement parts of a machine learning/data science project but at times, we just need high level steps offering clear guidance.

When I was new to machine learning and data science, I used to seek articles that clearly outlined the steps stating what I need to do to get my project done.

This article aims to provide an end-to-end guide for getting a successful machine learning project implemented.

 

With That In Mind, Let’s Start

 

In a nutshell, a machine learning project has three main parts: Data Understanding, Data Gathering & Cleaning, And Finally Model Implementation And Tuning. Usually, Data Understanding, Gathering And Cleaning Takes 60–70% Of The Time. And For That, We Need A Domain Expert.

 

Scenario

 
Let’s imagine you are attempting to work on a machine learning project. This article will provide you with the step to step guide on the process that you can follow to implement a successful project.

In the beginning, there are multiple questions arising in our brain

Data Science Is Trial And Error, It’s Research And Recursive, It’s Practical And Theoretical, It Requires Domain Knowledge, It Boosts Your Strategic Skills, You Learn About Statistics And Master Programming Skills. But Most Importantly, It Teaches You To Remain Patient As You Are Always Close To Finding A Better Answer.

 

Steps

 
Two Pre-requisite Steps:

1. Make sure you understand what machine learning is and its three key areas. Click to read:

Let’s Start The Implementation

 
1. Choose appropriate machine learning algorithm. Click to read:

Machine Learning Algorithms Comparison
There are a large number of Machine Learning (ML) algorithms available. In this article, I am going to describe and…medium.com

By now, you would have understood if it’s a supervised or unsupervised problem that you are attempting to resolve.

There is always a potential to find another right answer. There are often multiple right answers in a forecasting problem.

 
2. If it’s a supervised machine learning problem then ensure you understand if it’s regression or classification problem. Click to read:

Clean data in = Good results out.

 
10. Reduce Features Dimensions Space. Click to read:

What Is Dimension Reduction In Data Science?
We have access to a large amounts of data now. The large amount of data can lead us to create a forecasting model where…medium.com

If after enriching your features and reducing the dimensions, your model does not yield accurate results then look to tune the model parameters.

 
11. Fine-Tune your machine learning model parameters. Click to read:

How To Fine Tune Your Machine Learning Models To Improve Forecasting Accuracy?
Fine tuning machine learning predictive model is a crucial step to improve accuracy of the forecasted results. In the…medium.com

Always ensure you are not over-fitting or under-fitting

 
12. Finally, Repeat These Steps Until You Get Accurate Results:

  1. Enrich Features
  2. Fine Tune Model Parameters

Always analyse your data set and see if you are missing any important information, resolve the problems when you see them but always take a back up and save your work as you might be required to go back to the previous step.

Machine Learning Is Recursive In Nature

 

Summary

 
I wanted a simple page that listed out the steps which we need to follow to implement a machine learning model. This article aimed to provide an end-to-end guide for getting a successful machine learning project implemented.

Hope it helps.
