Top 10 Principal Real-World Applications of Data Science

Understanding the day-to-day applications of data science in the real world
Data science and artificial intelligence are the revolutionary technologies that are changing the modern era. We are currently witnessing the advantages of fast-paced computers and game-changing business models and ideas in our daily lives. Various industries like manufacturing, finance, e-commerce, and education, to name a few, have implemented data science as a part of their daily activities.

Data science has become an integral part of every industry. It is the extraction of meaningful data from organized and disorganized raw data sets using statistical algorithms and scientific techniques. These predictions help businesses understand the current and future market trends and customer expectations to help prevent financial losses.

This article brings you to the top 10 chief applications of data science in the real world.

Finance: Data science has played a crucial role in automating financial tasks. Finance industries and banks are using data science for automated risk analysis to carry out strategic decisions for the company. Using different ML and data science algorithms, businesses monitor and prioritize the risks to enhance cost efficiency and sustainability of the business model through training based on the massively available customer data. Predictive analytics and NLP have contributed massively to the transformation of the finance industry.

Healthcare: The healthcare sector has also benefitted from data science applications. Medical image analysis helps detect tumors, artery stenosis, and other diseases, which allows healthcare providers to give the best treatment to their patients and with minimum errors. It has also enabled advanced levels of personalized treatments through research in genetics and genomics. Advancement in drug development and virtual assistance to patients are also some of the many reasons we can say that data science applications have improved our living standards.

Image Recognition: Data science tools have started identifying the human face and matching the face with all the pictures available in its database. The vast amounts of digital data stored and uploaded through mobile phones to the internet are used by companies to provide better services to their customers. These tools are not only used for face recognition but also for identifying and naming objects in pictures. Data science can recognize any special patterns, including expressions or facial textures, and matches them with its database.

Transport: In the transportation sector, data science is making its mark by ensuring a safer driving environment. It is playing a crucial role in optimizing vehicle performance and giving more autonomy to the drivers. Also, self-driving cars are one of the most trending topics in the world today. It is also helping vendors optimize delivery routes and addresses properly by using different variables like customer’s location, profile, economic indicators, logistics, and other related information.

Advancement in Security Systems: Businesses are using different data science and machine learning algorithms to protect sensitive information. These algorithms help detect fraud based on any deviations from the users’ normal financial activities. With the help of processes like encryption, companies prevent misuse of customers’ information, including card details, contact information, and others.

Internet Search: Different search engines like Google, Bing, Yahoo, AOL, and so on are using data science algorithms to deliver the best results for the searched query within a fraction of seconds.

Autocorrect: Autocorrect is based on AI methodologies to achieve the best results while typing or texting to avoid incorrect statements or words. The spellings are automatically checked and are immediately corrected to the nearest high values. Identifying the misspelled word while computing the minimum edit distance and then filtering the right words for the users. These technologies ensure the best user experience while using any texting application or gadget.

Chatbots: Chatbots are universally used today on many websites and applications to interact with users and attend to their queries. Chatbots save time as well as reduce human labor and expenditure. There are various types of chatbots, each specialized in a particular field.
