What is Machine Learning?

Even though there are various Machine Learning examples or applications that we use in our daily lives, people still get confused about Machine Learning, so let’s start by looking at the Machine Learning definition.

In layman’s terms, Machine Learning can be defined as the ability of a machine to learn something without having to be programmed for that specific thing. It is the field of study where computers use a massive set of data and apply algorithms for ‘training’ themselves and making predictions. Training in Machine Learning entails feeding a lot of data into the algorithm and allowing the machine itself to learn more about the processed information.

Answering whether the animal in a photo is a cat or a dog, spotting obstacles in front of a self-driving car, spam mail detection, and speech recognition of a YouTube video to generate captions are just a few examples out of a plethora of predictive Machine Learning models.

Machine Learning can also be defined as a subset of Artificial Intelligence that comprises algorithms programmed to gather information without explicit instructions at each step. It has experienced the colossal success of late.

We have often seen confusion around the use of the words Artificial Intelligence and Machine Learning. They are very much related and often seem to be used interchangeably, yet both are different. Confused? Let us elaborate on AI vs. ML vs. DL.

Why Machine Learning?

Let us start with an instance where a machine surpasses in a strategic game by self-learning. In 2016, the strongest Go player (Go is an abstract strategy board game invented in China more than 2,500 years ago) in the world, Lee Sedol, sat down for a match against Google DeepMind’s Machine Learning program, AlphaGo. AlphaGo won the 5-day long match.

Why Machine Learning

Machine Learning has paved its way into various business industries across the world. This incredible impact of Machine Learning on propelling business growth, simplifying repetitive tasks, elevating customer satisfaction, and reaching corporate objectives is what fuels its success.

According to BCC Research, the global market for Machine Learning is expected to grow from $17.1 billion in 2021 to $90.1 billion by 2026 with a compound annual growth rate (CAGR) of 39.4% for the period of 2021-2026.

Moreover, Machine Learning Engineer is the fourth-fastest growing job as per LinkedIn.

How Does Machine Learning Work?

Machine learning operates with a variety of algorithms and techniques, which are formulated using specific programming languages designed for machine learning purposes. Typically, these algorithms undergo training using a dataset to construct a model. Later, when fresh input is supplied to the machine learning algorithm, it produces a result or prediction based on the established model. If the prediction is correct, it is considered dependable, and the algorithm is employed. However, in case of an inaccurate prediction, the algorithm goes through additional training with the dataset until it can yield precise outcomes.

For example, If you wish to predict the weather patterns in a particular area, you can feed the past weather trends and patterns to the model through the algorithm. This will be the training dataset for the algorithm. Now if the model understands perfectly, the result will be accurate.

Different Types of Machine Learning

Machine Learning algorithms run on various programming languages and techniques. However, these algorithms are trained using various methods, out of which three main types of Machine learning are:

  • Supervised Learning
  • Unsupervised Learning
  • Reinforcement Learning

1. Supervised Learning

Supervised learning, often called supervised machine learning, is a branch of artificial intelligence and machine learning. It stands out by using labeled datasets to teach algorithms to sort data or make accurate predictions. The model fine-tunes its parameters as it receives input data, which is a part of the validation process. Supervised learning is valuable for organizations dealing with various real-world challenges, like segregating spam emails into a different folder from your regular inbox.

2. Unsupervised Learning

Unsupervised learning, sometimes referred to as unsupervised machine learning, employs machine learning algorithms to examine and group unmarked datasets. These algorithms uncover concealed trends or data groupings independently, without requiring human input. Its knack for uncovering likenesses and disparities in data makes it an excellent choice for tasks like exploring data, developing cross-selling tactics, segmenting customers, and recognizing images.

3. Reinforcement Learning

Reinforcement Learning (RL) is all about making decisions wisely. It’s the process of figuring out the best way to behave in a certain situation to get the most significant reward. This smart behavior is learned by engaging with the surroundings and seeing how it reacts, kind of like kids exploring the world and figuring out what actions get them closer to their goals.

Without someone guiding the way, the learner has to figure out on its own which sequence of actions brings the best rewards. This figuring-out part is a bit like trying things out and learning from the results. The quality of actions isn’t just based on the immediate rewards; it’s also about the rewards that come later. Since it can learn how to succeed in a new place without any help, reinforcement learning is a pretty impressive method.

Machine Learning Algorithms and Processes

Machine Learning algorithms are sets of instructions that the model follows to return an acceptable result or prediction. Basically, the algorithms analyze the data fed to them and establish a relationship between the variables and data points to return the result.

Over time, these algorithms learn to become more efficient and optimize the processes when new data is fed into the model. There are three main categories in which these algorithms are divided- Supervised Learning, Unsupervised Learning, and Reinforcement Learning. These have already been discussed in the above sections.

Disadvantages of Machine Learning

  • Data Acquisition

Machine Learning requires a massive amount of data sets to train on, and these should be inclusive/unbiased, and of good quality. There can also be times where we must wait for new data to be generated.

  • Time and Resources

Machine Learning needs enough time to let the algorithms learn and develop enough to fulfill their purpose with a considerable amount of accuracy and relevancy. It also needs massive resources to function. This can mean additional requirements of computer power for you.

  • Interpretation of Results

Another major challenge is the ability to accurately interpret results generated by the algorithms. You must also carefully choose the algorithms for your purpose. Sometimes, based on some analysis you might select an algorithm but it is not necessary that this model is best for the problem.

  • High error-susceptibility

Machine Learning is autonomous but highly susceptible to errors. Suppose you train an algorithm with data sets small enough to not be inclusive. You end up with biased predictions coming from a biased training set. This leads to irrelevant advertisements being displayed to customers. In the case of Machine Learning, such blunders can set off a chain of errors that can go undetected for long periods of time. And when they do get noticed, it takes quite some time to recognize the source of the issue, and even longer to correct it.

Future Scope of Machine Learning

The scope of Machine Learning covers varied industries and sectors. It is expanding across all fields such as Banking and Finance, Information Technology, Media & Entertainment, Gaming, and the Automotive industry. As the Machine Learning scope is very high, there are some areas where researchers are working toward revolutionizing the world for the future.

The scope of Machine Learning in India, as well as in other parts of the world, is high in comparison to other career fields when it comes to job opportunities.

According to Gartner, there will be 2.3 million jobs in the field of Artificial Intelligence and Machine Learning by 2023. Also, the salary of a Machine Learning Engineer is much higher than the salaries offered to other job profiles. According to Forbes, the average salary of an ML Engineer in the United States is US$99,007.
