Introduction to Machine Learning and its Applications

Machine learning (ML) is a type of artificial intelligence (AI) that enables you to predict results accurately, even if your application software is not explicitly programmed. Machine learning algorithms use sample data as input to predict output values. In general, machine learning aims to understand the structure of data and adapt it to a model that humans can understand and use.

Machine learning as a service is a science that allows computers and machines to learn without being explicitly programmed. ML is one of the most exciting technologies when compared to others. As the name implies, it is the ability to learn that gives computers humanity. Machine learning is being actively used very widely today. Similar to how the human brain gains knowledge and understanding, machine learning relies on inputs such as training data and knowledge graphs to understand domains, entities, and their connections. The machine learning process begins with observations or data, such as samples, first-hand experiences, and instructions. It looks for patterns in the data so can make inferences later based on the sample provided. The main goal of ML is to enable computers to learn autonomously and adapt their actions accordingly without human intervention or assistance.

How has machine learning evolved?

Early computers were designed to perform complex calculations, and their architecture allowed them to store data and instructions for manipulating it. This has led computers to process data according to real-world mathematical and structural models. The computer didn’t learn; it just followed the instructions. The subsequent step was to create instructions that allow the computer to learn from experience. For example, extracting rules from a large amount of data and using these rules for classification and prediction.

This was the foundation of machine learning and led to a field collectively known as artificial intelligence. The major breakthrough was achieved by implementing an algorithm that roughly modeled the brain’s architecture. Many aspects of modern life have been revolutionized by AI, and it is increasingly being applied to clinical practice and biomedical research.

How Does Machine Learning Work, and Who Uses It?

Machine learning uses two main techniques.

  • Supervised learning can be used to collect data from previous ML deployments and generate data output. Supervised learning is exciting because it works the same way humans actually learn. A monitored task presents a collection of labeled data points to a computer called a training set, for example, a set of readings from a system of train terminals and markers that have been delayed in the last three months.
  • Unsupervised machine learning helps you find all sorts of unknown patterns in your data. In unsupervised learning, the algorithm attempts to learn the unique structure of the data using only unlabeled examples. Two common unsupervised machine learning tasks are clustering and dimension reduction techniques.

Clustering data points into meaningful clusters is done so that items in a particular cluster are similar to each other but different from items in other clusters. Clustering is useful in market segmentation. Dimensional reduction models decrease variants in a dataset by grouping correlated or similar attributes for better interpretation and understanding. From tedious manual data entry automation to more complex use cases such as insurance risk assessment and fraud detection, machine learning has many applications that include customer-facing features such as customer service and product recommendations. A big part of what makes machine learning so valuable is the ability of the human eye to find what it misses. Machine learning models can recognize complex patterns that human analysts might have missed.

What Are the Different Types of Machine Learning?

Types of machine learning

Types of machine learning


Supervised machine learning

As the name implies, supervised machine learning is based on supervised learning. In supervised learning techniques, this means training the machine with a “tagged” dataset and having the machine predict output based on the training. Here, the labeled data shows that some inputs have already been mapped to outputs. First, train the machine with the inputs and corresponding outputs, then ask the machine to use the test dataset to predict the outputs.

Unsupervised machine learning

Unsupervised learning is different from supervised learning techniques. As the name implies, no supervision is needed. This means that in unsupervised machine learning, the machine is trained on an unlabeled dataset and predicts output unsupervised. In unsupervised learning, the model is trained with unclassified and unlabeled data, and the model manipulates that data unsupervised.

Semi-supervised learning

Semi-supervised learning is a type of machine learning algorithm that represents an intermediate stage between supervised (with labeled training data) and unsupervised (without labeled training data) and uses a combination of labeled and unlabeled data sets during the training period.

Reinforcement learning

Reinforcement learning works in a feedback-based process where AI agents (software components) automatically explore the environment through trial and error, take actions, learn from experience, and improve performance. Agents are rewarded for good behavior and punished for bad behavior. Therefore, the goal of reinforcement learning agents is to maximize rewards.

The Importance of Machine Learning

The concept of machine learning is used almost everywhere, for example, in areas such as healthcare, finance, infrastructure, marketing, self-driving cars, recommendation systems, social sites, chatbots, games, and cyber security. Machine learning is important because it gives companies an overview of customer behavior and trends in operational business patterns and supports the development of new products.

Many of today’s big companies, such as Facebook, Google, and Uber, have machine learning at their core. Machine learning has become an important differentiator for many organizations. Machine learning has several practical applications that drive real-world business outcomes that can dramatically impact your organization’s future, such as saving time and money. In particular, machine learning has greatly impacted the customer care industry, empowering people to do things faster and more efficiently.

Machine Learning: Challenges

Not enough training data

Most algorithms require large amounts of data to work properly. Simple tasks can use thousands of examples to create them, and advanced tasks such as image and speech recognition can use millions of examples.

Poor data quality

If your training data contains a lot of errors or invalid samples, your machine learning model will not be able to identify the correct underlying pattern. Therefore, it does not work well.

Non-representative training data

For the model to be properly generalized, the training data must represent a new case of generalization. Training a model with a non-representative training set results in inaccurate predictions and biases against classes or groups.

Real-World Machine Learning Use Cases

  • Today’s video surveillance systems utilize AI to detect crimes before they occur. They track anomalous human behavior, such as standing still for long periods of time, tripping, or taking a nap on a bench.
  • There are many spam filtering approaches used in email clients. These are enhanced by machine learning to ensure that these spam filters are continuously updated.
  • Today, many websites offer the opportunity for customer service personnel to chat while navigating the website. However, not all websites have a live manager to answer your questions. Most of the time, you talk to a chatbot that extracts information from websites and presents it to its customers.
  • Search engines use machine learning algorithms to improve search results. The back-end algorithm monitors your reaction to the results each time you perform a search.

What Is the Future of Machine Learning?

The future of machine learning is very exciting. Currently, almost all common domains of machine learning applications are supported. Healthcare, search engines, digital marketing, and education are the main beneficiaries, to name just a few of these industries. ML can be controversial for companies or organizations, as tasks that are currently being performed manually are expected to be performed entirely by machines in the future. Machine learning is the greatest benefit of AI for humankind to reach its goals effectively. The areas of computer vision and natural language processing (NLP) are making breakthroughs that no one had predicted. Face recognition on smartphones, language translation software, self-driving cars, etc. are a few examples in our lives. What may look like science fiction is becoming reality. Machine learning plays such a huge role in our lives today that it is difficult to imagine the future without it.

Machine Learning vs. Deep Learning

Deep learning is a subset of machine learning, where artificial and recurrent neural networks interact. Algorithms are created in the same way as machine learning, but they are made up of more layers of algorithms. All of these algorithmic networks are collectively referred to as “artificial neural networks.”. Simply put, all the neural networks in the brain are interconnected, so they replicate like the human brain. This is exactly the concept of deep learning. It solves all complex problems with the help of algorithms and their processes.

Machine learning is the ability of computers to act and think with minimal human intervention. Deep learning is a computer learning to think using a structure modeled on the human brain. Less computing power is required for machine learning. Deep learning usually requires less continuous human intervention.

What Should Be The Way Forward?

To speed up your machine learning journey, you need to easily identify some simple outcomes and ways to integrate ML into your existing operations. Integrating ML into existing applications is a great way to quickly see results while preparing your organization for more machine learning in the future. Integrating ML with existing data providers and databases can improve data quality immediately. Machine learning has several use cases for data collection, cleaning, and labeling. Most importantly, enhancing and structuring existing data will help organizations make better use of it in future ML projects.
