Machine Learning: A Complete Guide with Real Life Use Cases

Machine Learning is one of the advanced innovations that has assisted humans in improving several professional and industrial processes and advancing our routine life. But, first and foremost, what is machine learning? A subset of artificial intelligence focuses on using statistical approaches to construct intelligent computer systems that can learn from databases. Machine learning is currently utilized in a diversity of sectors and industries. Medical diagnosis, image processing, prediction, classification, learning association, regression, and so on are only a few examples.

Machine learning algorithms enable intelligent systems to learn from both experience and historical data. The outputs of machine learning applications are based on previous experience. We’ll look at some real-world examples of how machine learning assists in developing better technology to fuel today’s ideas in this post.

Image Recognition

One of the most common applications of machine learning is image recognition. You can classify an object as a digital picture in a variety of ways. In the case of a black and white image, for example, one of the metrics is the intensity of each pixel. Each pixel in a colorful image produces three intensity measures in three distinct colors — red, green, and blue (RGB).

Face detection in an image can also be done using machine learning. Each person in a database of numerous people has their category. Character recognition, both handwritten and printed, is another use of machine learning. A piece of writing can be divided into smaller images, each having a single character.

Medical diagnosis

Machine learning can be applied to approaches and systems that aid in disease diagnosis. For example, it is used to assess clinical parameters and combinations for prognosis, illness progression prediction, and medical knowledge extraction for outcome research, therapy planning, and patient monitoring. These are the successful implementations of the Machine Learning Techniques. It can assist in the combination of computer-based systems in the healthcare sector.

Speech Recognition

The translation of spoken words into writing is known as speech recognition. It’s sometimes referred to as automatic voice recognition or computer speech recognition. In this case, a software program may recognize the words spoken in an audio clip or file and convert the audio to text. In this case, the measurement can be a series of numbers that reflect the voice signal. We can additionally segment the voice signal into distinct time-frequency bands based on its intensity.

Speech recognition is utilized in various apps, including voice user interfaces, voice searches, and more. Voice dialing, call routing, and appliance control are all examples of voice user interfaces. It can also be used to enter simple data and create structured documents.

Statistical Arbitrage

Arbitrage is a phrase used in finance to describe short-term automated trading methods that include many securities. In these techniques, the user develops a trading algorithm for a group of stocks using data such as historical correlations and macroeconomic indicators. To obtain an index arbitrage strategy, machine learning approaches are used. We employ linear regression and the Support Vector Machine to the values of a stream of stocks.


Classification is the process of assigning each understudy to several different classes. Classification aids in analyzing an object’s measurements to determine the category to which it belongs. Analysts use data to develop a productive relationship. Before deciding to distribute loans, a bank, for example, examines the customers’ ability to repay them. We can do it by reflecting the parts like customer’s earnings, savings, and financial history. This information is obtained from past data on loans.

Learning associations

Learning associations is the process of developing insights into the various associations between the products. A good example is how unrelated products can be associated with one another. One of the applications of machine learning is studying the associations between the products that people buy. Because there is a relationship between the two things, he will be presented with related products when a consumer buys one. When new products are introduced, they are often paired with older ones to boost sales.


Prediction systems can also benefit from machine learning. In the loan case, the system will need to classify the available data to determine the chance of a defect. It is defined by a set of rules that the analysts have established. We can determine the probability of the fault once the classification is complete. These computations can measure across all the areas for different purposes. Executing predictions is one of the best machine learning solutions.


One of the most practical uses of machine learning is data extraction. It extracts structured data from unstructured data, such as web pages, articles, blogs, business reports, and emails. The outcome of the information extraction is stored in a relational database. The extraction method takes a set of documents as input and produces structured data.


In the regression, we can also use machine learning. We can apply the principle of machine learning to optimize the parameters in regression. It can also be used to reduce approximation error and calculate the most accurate feasible result. Machine learning can also be used to optimize functions. We can also opt to change the inputs to achieve the most accurate result.

Financial Services

In the financial and banking sectors, machine learning has a lot of potentials. It is the driving reason for financial services’ appeal. Banks and financial institutions can benefit from machine learning to make better decisions. Machine learning can assist financial services in anticipating account closures. It can also monitor a customer’s spending habits. Machine learning can also be used to do market research. It is possible to train smart machines to track spending trends. The algorithms are capable of quickly detecting patterns and reacting in real-time.


In a nutshell, we can tell that machine learning is an unbelievable discovery in artificial intelligence. And while machine learning has some terrifying implications, these machine learning solutions are one of the ways technology can enhance our lives.
