Many people can use the perfect instrument, but only a few can design and create one to be used by the many.
We live in a privileged era of technological advancements that have made life so much easier and enjoyable. Many of these technologies that we may take for granted are powered by “Artificial Intelligence (AI).”
AI is the science behind creating systems and machines that can emulate humans in performing various tasks. Often, Machine Learning (ML) and Artificial Intelligence (AI) are used together. If the goal of AI is to try to emulate humans, then machine learning is a method by which we can train a machine to learn and recognize patterns from data. The machine is trained enough to perform specific tasks for us, with minimal human intervention. Machine Learning, hence, forms a key role in achieving AI.
Machine Learning is a topic that’s on the mind of just about every industry. The major hiring happening in all top tech companies today is in search of those specially skilled people (machine learning engineers) who can build that perfect instrument (machine learning algorithms).
Today, machine learning capabilities are being widely applied, and it is changing the business landscape in dynamic ways. Some of the biggest corporations use machine learning, and we can be sure that its influence is only going to grow more in the coming years. Learning machine learning can position one for a variety of exciting careers in a growing number of industries.
While machine learning is becoming a more widely accepted and adapted technology, individuals who are considering their future career options are still somewhat hesitant to step into the machine learning arena.
The reason for this hesitation could be that the technology involved in machine learning is still a little elusive for many, which has those considering this career path wondering how difficult it is to master machine learning and whether it’s a career they’re well suited for.
Let’s answer these questions by taking a more in-depth look at what exactly machine learning is and what it takes to excel in the field.
What is Machine Learning?
Machine learning is the technique of creating systems that can ‘analyze’ pre-existing data, and ‘learn’ patterns and make decisions/predictions/classifications or other tasks on similar data, with minimal human intervention. An analogy can be made with how humans learn with experiences. As humans learn from the experiences of the past to make better decisions in the future, ML is the technique of training a computer to learn from historical data to perform tasks for us in a better manner in the future.
A natural comparison between machine learning and traditional programming can be made. However, machine learning differs from traditional programming in several ways. With traditional programming, a human workforce feeds data into a computer and develops a program that’s designed to transform that data into the desired output. Computer programming is a very human-involved process, and it’s limited to our capabilities of structuring and defining data.
In contrast to traditional programming, with machine learning, we feed data into the machine and based on what has been previously fed, the machine develops its logic based on the desired output. In other words, machines learn without us interfering in the process. It may seem like something that's limited to research work, there are many machine learning applications that we encounter daily.
Machine learning is not programmed; it is taught with data.
Let's take Google, for example. They’re masters at applying machine learning to enrich their user’s search engine experience. Through machine learning, Google can better understand the intent of each of your search queries and place the most relevant results in front of you. It’s what makes Google so well-loved.
Machine Learning is used in practically every industry. It’s widely employed by social media networks to create a more personalized, enjoyable experience for social media users. But machine learning also has more practical applications. For instance, machine learning technology is being leveraged in the healthcare field to help improve patient care and help avoid lapses that occur due to human error. It allows doctors more efficiently use diagnostic tests and equipment to detect diseases such as early-stage cancer that often go unnoticed in the beginning stages.
Machine learning is a critical component of Artificial Intelligence. We can break AI into several distinct levels. Machine learning, where machines use algorithms to learn from previous experiences and data inputs, is the base level of AI technology. Also, just as the basis of AI is machine learning, the foundation of an effective machine learning implementation is useful data, i.e., data science.
Why Learn Machine Learning?
“Artificial Intelligence, deep learning, machine learning — whatever you’re doing if you don’t understand it — learn it. Because otherwise, you’re going to be a dinosaur within three years.” - Mark Cuban
As mentioned earlier, It’s impossible to look into the future and not see AI as being a driving force behind economic growth in one capacity or another. There is a tremendous growing need for businesses in all industries to adapt to AI and machine learning, and that means they’re going to need machine learning professionals who can lead them into the future.
In 2016, machine learning was a $1.03 billion industry. By 2022, that number is expected to grow to $8.81 billion. Machine learning is moving well past being a niche area of computer science. The average person encounters some form of machine learning practically daily, often without realizing it. This alone illustrates how entrenched machine learning already is in our lives and the potential for it to enrich our lives further.
Machine learning has experienced exponential growth in recent years, and there’s currently a demand for machine learning professionals that can help companies throughout various industries identify opportunities for implementation of the technology and the most effective, profitable ways to use it.
