Even if you’re unfamiliar with the specifics, you probably benefit from machine learning on a daily basis. For example, you use ML when you use your smartphone’s maps app to find a friend’s house or when you ask Siri to play your favorite song one more time. Simply put, machine learning is a branch of artificial intelligence that uses data to create, train, and refine algorithms that can make predictions or decisions with little or no human intervention.
Machine learning is a rapidly expanding field in the technology industry, as well as a focus in a variety of industries. Given the high demand for machine learning skills in today’s job market, understanding the fundamentals can serve as an enticing pathway for anyone considering a job in technology or changing careers.

How Does Machine Learning Work?
Machine learning aims to teach computers (i.e. machines) to learn from experience. This is accomplished through the use of algorithms, which employ computational methods to directly “learn” information from data sets. As the amount of data available grows, the algorithms’ accuracy and performance, improve.
Because ML is used in so many different industries, your areas of interest will determine how you learn it. Are you interested in data science? ML is an important data analytics skill that is required to qualify for in-demand roles. We will look at how ML works in six different industries in this article: finance, business, genetics and genomics, healthcare, retail, and education.
Types of Machine Learning
Machine learning employs three primary techniques: supervised learning, unsupervised learning, and reinforcement learning. The most popular of the three is supervised learning, which trains a model to predict future outputs based on existing input and output data, similar to using flash cards as a teaching method. An algorithm is first introduced with pairs of inputs and outputs. The algorithm learns the nature of the input-output relationship over time in order to predict an output from a new input. One real-world example is your email spam filter, which learns what spam looks like (input) and then learns to distinguish spam from other mail (output).
Unsupervised learning is a completely different story. Instead of selecting a preferred output for the algorithm, it is fed a data set and given the tools to understand its properties. From there, it discovers hidden patterns in input data and can learn to organize the data logically in order to better analyze the set. The “recommended” section on a streaming service is an example of this: the website assesses its videos for length, topic, and other categories, and then uses data on what you’ve watched in the past to recommend what you should watch in the future.
Reinforcement learning uses reinforcement mechanisms to train a machine. In its early stages, a reinforcement learning system will make numerous errors. However, the machine learns from its mistakes and receives signals indicating errors or accuracy over time.
Benefits of Machine Learning
- Automation: Machine learning enables businesses to automate a wide range of tasks, increasing efficiency, and cost-effectiveness.
- Less reliance on human interaction: Because ML is almost entirely based on algorithms, managers don’t have to worry about balancing team dynamics in order to complete a critical task.
- Potential for improvement: Since it is constantly improving and evolving, machine learning algorithms can constantly build on their own knowledge and functionality bases.
- Efficient data handling: At this point, machine learning can analyze any type of data, including multidimensional data, making it extremely useful for data analysis and data science.

Uses of Machine Learning in Different Industries
Machine learning is frequently used to predict an output or to reveal and comprehend trends, and it is especially useful when the data is structured or already labeled. ML is particularly useful for analyzing and organizing data such as videos, images, and audio files due to the ease with which it can categorize and assess this type of data. When simple rules or computations fail to predict a target value, or when dealing with a particularly large data set, machine learning comes in handy.
ML is used in a plethora of industries, not just the tech-heavy ones that come to mind when you think of someone manipulating a massive data set. Here, we will discuss machine learning use cases by industry, highlighting some of the various ways that this tool is currently being used by a variety of people and businesses.
ML Applications in Finance
Analysts in the financial services industry use machine learning to automate trading activities, detect fraud, and provide financial advice to their clients. Algorithmic trading necessitates the development of mathematical models capable of monitoring news feeds and trading trends in order to forecast a rise or fall in security prices. Machine learning is also used by finance companies to detect fraudulent activity by comparing transactions to other existing data points (e.g., they know if that $500 Amazon purchase is something you’re likely to do, or if it’s completely out of character for you and thus suspicious). Robo-advisors built with machine learning in portfolio management provide investors with automated financial advice based on their goals, risk aversion, and other factors.
ML Applications in Business
Machine learning provides businesses with numerous opportunities to improve their effectiveness, efficiency, and offerings. Chatbots, for example, enable businesses to provide faster, more flexible customer service without employing a call center or keeping customers on hold while waiting for the next available representative. Internally, businesses use machine learning to aid decision making, allowing teams to rely on algorithms to make resource management decisions or identify trends and problems more quickly. Machine learning also assists businesses in dealing with customer churn by analyzing data to determine how and why businesses lose customers.
ML Applications in Genetics and Genomics
The genetic code is one of the most comprehensive data sets ever studied. Humans have over 20,000 distinct genes, each with the potential for variation. Machine learning enables researchers to better understand various genetic traits and abnormalities by analyzing and comprehending massive data sets. For example, machine learning assists scientists in identifying genetic variants shared in individuals with traits being studied, such as hemophilia or diabetes, allowing them to better understand where these disorders originate in the genome. It can occasionally assist researchers in understanding why they occur in the first place.
ML Applications in Retail
As previously stated, machine learning can be extremely beneficial in understanding and reducing customer churn (the rate at which a business loses customers each year), which is a major focus for many retail companies. According to Salesforce, 83 percent of IT experts believe that companies that use AI have higher levels of customer engagement. Machine learning applications also assists retailers in synthesizing the nearly limitless amount of consumer data available to them but nearly impossible to understand using basic human analysis.
ML Applications in Education
Machine learning can assist educational institutions with both process-based tasks and student-centered initiatives. Statistical models can help comprehend student progress and needs, while scheduling algorithms can help institutions of all sizes create more efficient and streamlined schedules.
ML Applications in HR Management
Human resource machine learning illuminates the development of a more people-centric approach, paving the way for more valuable programs and less wasted time; reduced bias in programs; less administration and more individual development; and the ability to act proactively rather than reactively, seamlessly moving from the individual to the organizational level and back again.
