Top 10 Machine Learning Applications in 2020

Machine learning is the latest buzzword sweeping across the global business landscape. It’s captured the popular imagination, conjuring up visions of futuristic self-learning AI and robots. In industry, machine learning has paved the way for technological accomplishments and tools that would have been impossible a few years ago. From prediction engines to online TV live streaming, it powers the breakthrough innovations that support our modern lifestyles.

Now, before we get into the various machine learning applications, let us first understand what Machine learning is.

What is Machine Learning?

Machine learning is an umbrella term for a set of techniques and tools that help computers learn and adapt on their own. Machine learning algorithms help AI learn without being explicitly programmed to perform the desired action. By learning a pattern from sample inputs, the machine learning algorithm predicts and performs tasks solely based on the learned pattern and not a predefined program instruction. Machine learning is a life savior in several cases where applying strict algorithms is not possible. It will learn the new process from previous patterns and execute the knowledge.

One of the machine learning applications we are familiar with is the way our email providers help us deal with spam. Spam filters use an algorithm to identify and move new kinds of junk messages to your spam folder. Several e-commerce companies also use machine learning algorithms in conjunction with other IT security tools to prevent fraud and improve their recommendation engine performance.

Let’s explore other real-world machine learning applications that are sweeping the world!

1. Social Media Features

Social media platforms use machine learning algorithms and approaches to create some attractive and excellent features. For instance, Facebook notices and records your activities, your chats, likes, and comments, and the time you spend on specific kinds of posts. Machine learning learns from your own experience and makes friends and page suggestions for your profile.

2. Product Recommendations

One of the most popular and known applications of machine learning is Product Recommendation. Product recommendation is one of the stark features of almost every e-commerce website today, which is an advanced application of machine learning techniques. Using machine learning and AI, websites track your behavior based on your previous purchase, your searching pattern, your cart history, and make product recommendations.

3. Image Recognition

Image Recognition is one of the most significant and notable Machine Learning and AI techniques: an approach for cataloging and detecting a feature or an object in the digital image. This technique is being adopted for further analysis, such as pattern recognition, face detection, or face recognition.

4. Sentiment Analysis

Sentiment analysis is one of the most necessary Applications of Machine Learning. Sentiment analysis is one of the most necessary Applications of Machine Learning. Sentiment analysis is a real-time machine learning application that determines the emotion or opinion of the speaker or the writer. For instance, if someone has written a review or email (or any form of a document), a sentiment analyzer will instantly find out the actual thought and tone of the text. This sentiment analysis application can are used to analyze a review based website, decision-making applications, etc.

5. Automating Employee Access Control

Organizations are actively implementing machine learning algorithms to determine the level of access employees would need in various areas, depending on their job profiles. This is one of the coolest applications of Machine Learning.

Accelerate your career with the Post Graduate Program in AI and Machine Learning with Purdue University collaborated with IBM.

6. Marine Wildlife Preservation

Machine learning algorithms are used to develop behavior models for endangered cetaceans and other marine species, helping scientists regulate and monitor their populations.    

7. Regulating Healthcare Efficiency and Medical Services

Significant healthcare sectors are actively looking at using Machine Learning algorithms to manage better. They predict the waiting times of patients in the emergency waiting rooms across various departments of hospitals. The models use vital factors that help define the algorithm, details of staff at various times of day, records of patients, and complete logs of department chats and the layout of emergency rooms. Machine learning algorithms also come to play when detecting a disease, therapy planning, and prediction of the disease situation. This is one of the most necessary Applications of Machine Learning.

8. Predict Potential Heart Failure

An algorithm designed to scan a doctor’s free-form e-notes and identify patterns in a patient’s cardiovascular history is making waves in medicine. Instead of a physician digging through multiple health records to arrive at a sound diagnosis, redundancy is now reduced with computers making an analysis based on available information.

9. Banking Domain

Banks are now using the latest advanced technology machine learning has to offer to help prevent fraud & protect accounts from hackers. The algorithms determine what factors to consider to create a filter to keep harm at bay. Various sites that are unauthentic will be automatically filtered out and restricted from initiating transactions.

10. Language Translation

One of the most common applications of Machine Learning is Language Translation.Machine learning plays a significant role in the translation of one language to another. We are amazed at how the websites can translate from one language to another effortlessly and gives contextual meaning as well. The technology behind the translation tool is called ‘machine translation.’ It has enabled the world to interact with people from all corners of the world; without it, life would not be as easy as it is now. It has provided a sort of confidence to travelers and business associates to safely venture into foreign lands with the conviction that language will no longer be a barrier.

Your model will need to be taught what you want it to learn. Feeding relevant back data will help the machine draw patterns and act accordingly. So it is imperative to provide relevant data and feed files to help the machine learn what is expected. In this case, with Machine Learning – it is what you want as a result depends on the contents of the files that are being recorded.


Getting to know some of the popular applications of machine learning along with technology evolving at a rapid pace, we are excited about the possibilities which the Machine Learning course has to offer in the days to come. And as the demand for AI and machine learning has increased, organizations require professionals with in-and-out knowledge of these growing technologies and hands-on experience. Keeping the innate need in mind, Simplilearn has launched the AI and Machine Learning certification courses with Purdue University in collaboration with IBM that will help you gain expertise in various industry skills and technologies from Python, NLP, speech recognition, to advanced deep learning. This Post Graduate program will help you stand in the crowd and grow your career in thriving fields like AI, machine learning, and deep learning.
