A Brief History of Machine Learning

Despite its growing popularity, most experts still consider machine learning a subcategory of artificial intelligence (AI). Also known as ML, machine learning as a model dates back to the 1940s when psychologist Donald Hebb developed theories based on communication between neurons in the brain. Ultimately, so-called Hebbian theories developed into propositions based on artificial neural networks (ANNs) or computing systems based on biological brain functions.

By the 1960s, the success of the first neuro-computer paved the way for more developments in neural network research. However, the discipline of machine learning focuses primarily on problem-solving rather than products or services. It was not until the internet became popularized in the 1990s that machine learning grew into a discipline with broad applications to data-based industries of all types.

In the 21st century, the influence of machine learning has grown exponentially. Massive organizations like Google and Facebook have used ML algorithms successfully in facial and speech recognition programs, and the technology has expanded to virtually every multinational tech company. Machine learning algorithms work behind the scenes when you listen to songs on Apple Music or Spotify, watch shows on Netflix or Amazon Prime, or react to a video on Instagram or TikTok.

The potential of this broad-ranging field seems almost limitless. As ML models become more intuitive, companies will better use them to personalize customer experiences. Sales data analysis, fraud detection, and even management decisions can now increasingly be influenced or even accomplished with the help of machine learning algorithms. With ML, the future is already here.

Comparable Fields

When comparing careers in machine learning (ML) to other disciplines, it’s critical to keep one thing in mind: machine learning is a subcategory of artificial intelligence (AI), a subcategory of computer science.

Specializations within the broad computer science field include:

• Artificial Intelligence (AI)
• Game Design
• Information Security
• Data Science
• Software Engineering

Of these—and there are others, like programming, graphics, and networks—software engineering may be the most interesting to compare and contrast with ML.

Machine learning professionals and Software Engineers have much in common. Both need to master computer programming languages like Python, along with its many libraries and frameworks. They typically have strong backgrounds in math, computer science, or both. And they generally need to work with software and databases.

However, there are many more differences than similarities. ML professionals are much more specialized than Software Engineers, who usually need to learn more programming languages and processes. Whereas Software Engineers may follow a process from initial concept through updating an application, algorithms rather than humans may accomplish much of a machine learning professional’s needs.

A combination of the skills of both these positions is that of the Machine Learning Engineer. These professionals must know ML as well as generalized programming skills. Machine Learning Engineer positions often have AI in the title, such as AI/ML Engineering Leader, AI & ML Services Engineer, or Lead Software Engineer (AI/ML Ops). When looking for more information on ML or software engineering careers, consider the many combinations and the qualifications and responsibilities these positions require.
