Machine Learning Applications by Industry

  • Finance – Fraud detection is one of the top ML applications in finance. By looking at existing data for a customer, an anomaly detection model can identify fraudulent charges and flag them. In addition, in terms of AI and efficiency, investors can automate financial advice to be used in portfolio management.
  • Healthcare – From tracking disease to making administrative decisions and personalizing treatment options for patients, machine learning and AI is used in the medical field in both hospital and private practice settings.
  • Education – When K-12 schools and even universities need to optimize class scheduling, machine learning can be beneficial for streamlining processes. 
  • Retail – In our previous post, we reviewed examples of retail analytics, but this can go a step further. Analyzing customer engagement and customer churn can make a huge difference in ROI for retail companies, whether traditional brick-and-mortar stores or E-commerce stores.
  • Marketing – Marketing analysts can forecast sales by source or channel and use machine learning to automatically allocate marketing budgets across those channels.
  • Entertainment – Building a recommendation system for video, movie, and music streaming providers is a top application for ML in the entertainment industry.

12 Companies Using Machine Learning

1. Netflix

The first thing people think about when they hear that Netflix uses machine learning is recommendation systems. However, the company is using machine learning and AI for various projects. For the purpose of this example, we’ll focus on the article the company released this year on measuring the value of acquisition and retention in subscription services

The key takeaway from the article is that Netflix had to overcome a lack of data in their analysis and to do so they utilized Markov chains, a mathematical concept used in data science for probabilistic modeling. 

According to Netflix researchers, the finite Markov chain methodology can be used to “forecast future subscribers, estimate the impact of price change

on business metrics…” and more (Badri & Train, 2022, pg. 2).

2. Northwell Health

Northwell Health is the largest healthcare provider in New York state and in a 2021 article in Healthcare IT News, they explained how they’ve significantly reduced hospital readmissions with clinical AI.

The researchers highlight prescriptive analytics as a way to use ML models to make better operational decisions for the hospital. Northwell Health scientists go on to break down the complex topic by explaining that prescriptive analytics and ML allow clinicians to go  “beyond the data set that is limited by the human brain (Siwiki, 2021).

3. Citibank

As we explained earlier, a common use case for machine learning in finance is fraud detection. At Citibank, researchers used AI and ML models to detect payment transactions that were out of the norm, essentially detecting fraudulent purchases. 

They go on to describe the process of fine-tuning these models over time by feeding them more and more data.



As one of the big four audit and accounting firms, KPMG has several applications for machine learning and AI. In fact, they offer their patented AI platform (KPMG Ignite) that combines ML, deep learning, natural language processing (NLP), and more, for their clients. 

The machine learning software integrates with platforms like Microsoft Azure, Google Cloud, and IBM Watson to automate business decisions.

5. Western Governors University

When it comes to AI and ML applications in education, higher education institutions like Western Governors University in Utah incorporated Tableau, Databricks, Apache Spark, and Delta Lake on AWS to build a scalable platform for creating customized and skill-based education programs for students.

The full webinar is available on demand through WGU so that others can learn how the university is paving the way for ML and AI in higher education.

6. Shein

Most shoppers are now familiar with the Chinese online clothing brand, Shein. What many don’t know is that Shein leverages artificial intelligence as part of their business model. Specifically, the model they build can pick up fashion trends and demand patterns, allowing them to react in real time with inventory and pricing.

A recent report from PSFK, describes the company’s success with AI by combining social media data, e-commerce, and fintech.
