Artificial intelligence (AI) has always been a source of fascination for us, especially when it comes to how things can go wrong. From sci-fi thrillers like The Terminator and I, Robot to regular old science fiction exploration films like A.I. Artificial Intelligence and Bicentennial Man, popular media makes AI and the ethics and dangers surrounding it a common topic of study.

Fast-forward to the present day, and what was once thought of as unrealistic movie scenarios are now playing out in the real world. Spam detection in your inbox, Tesla’s self-driving cars, Amazon Alexa, and even your Netflix movie recommendations are all real-world applications of AI—and more specifically, machine learning.

What is machine learning and just how prevalent is it in our lives? Read on to find out.

What Is Machine Learning?

machine learning statistics

Machine learning (ML) is a type of artificial intelligence that involves the development and use of computer systems that can learn about and make predictions based on datasets without the need to follow explicit human instructions.

Generally, machine learning models use algorithms and statistical models to process historical data as an input, then use trends in this data to predict new output values. ML techniques are designed to make these predicted outcomes more accurate without the help of programming specifically tailored to produce a solution.

Said plainly: Machine learning platforms and software applications analyze data and draw conclusions from patterns it detects in that data.

Many common applications of machine learning technology are found in business, where it is used to improve performance in:

  • business analytics
  • risk management
  • performance analysis
  • reducing operating costs
  • assessing market opportunities

While business analytics and data-driven sports decisions may grab the bulk of the attention, applications for machine learning abound, and the market is rapidly expanding. For instance, some are seeking to adopt machine learning for meaningful tasks such as detecting breast cancer, or for financial gain by predicting stock market highs and lows.

No matter the use case, machine learning adoption has grown by leaps and bounds in the past decade. In fact, you probably interact with machine learning applications on a daily basis without even realizing it. Machine learning is used in:

  • email filters to sort out spam
  • internet search engines to understand user intent and result relevancy
  • banking apps to detect unusual or fraudulent activity in your bank accounts or credit cards
  • word processing software using natural language processing (NLP) to predict what words you’ll write next

Given a vast global machine learning market, it’s nearly impossible to not interact with some application of artificial intelligence in our daily lives.

But to get an idea of just how large this technological revolution this is, check out these top machine learning statistics and trends.

Related Machine Learning Statistics Questions

question and answer faq

How are statistics used in machine learning?

Statistics is the study of and manipulation of data. It contains a collection of tools and methods for evaluating, displaying, and interpreting sets of data, which can then be used to make decisions.

Machine learning algorithms use statistics to identify data patterns and convert those patterns into useful information, which data scientists and others then use to make informed decisions.

What are the differences among machine learning, AI, and data mining?

Artificial intelligence (AI) involves creating machines that can think and make decisions similar to humans. “Data mining is considered the process of extracting useful information from a vast amount of data. … On the other hand, machine learning is the process of discovering algorithms that have improved courtesy of experience derived from data” Put more simply, data mining is more akin to research, while machine learning is more akin to teaching machines how to use data and become more intelligent. (Source: Simplilearn)22

Will machine learning replace jobs?

Yes and no. While it is true that machine learning and related AI systems are quickly replacing repetitive jobs that can be more easily automated, the growth in the machine learning market has led to increased job opportunities in the fields of computer science and data engineering. With the rapid growth of machine learning adoption, it’s certain that these in-demand skills will also lead to the creation of millions of new jobs (including, of course, machine learning engineers). (Source: Built In)23

What are the drawbacks to machine learning?

Machine learning is only as good as the data it has available to it. If data collection is inadequate, then the machine learning algorithm will fail to produce meaningful predictions and information.

Thus, a machine learning algorithm needs large sets of good data to train on, plus the time to learn and develop, and adequate computing power to run.

Furthermore, because machine learning is dependent on the availability of large amounts of quality data, it is highly susceptible to error. Small training data sets often contain biases, which could result in biased and errored predictions. (Source: HBR)24
