  • Development of Drugs: The process of discovering new drugs is extremely difficult and encompasses numerous disciplines. Implementing brilliant ideas is time-consuming, money-intensive, and requires a massive number of testing. It may take up to twelve years normally to submit a form. This process is made simpler and quicker by data science applications and machine learning algorithms, providing context to each stage from the first screening of medicinal compounds through the prediction of the success rate with reference to biological parameters. In place of conducting "lab tests," a prediction can be brought forward by these algorithms forecasting the substance reaction in the body through sophisticated simulations and mathematical models. The purpose of computational drug development is to develop computer simulations as biologically relevant networks that make future outcome prediction easier and more accurate.

  • Virtual assistance for patient and customer support services: The idea that it is frequently unnecessary for patients to see doctors in person is the foundation for optimizing the clinical process. By sending the doctor to the patient directly, a mobile application can provide a more practical option. The mobile AI-powered apps, which are typically chatbots, can offer rudimentary healthcare support. Simply by describing your symptoms or posing inquiries, you can obtain important knowledge about your medical condition drawn from a large network that connects symptoms to causes. Apps can schedule a doctor's appointment for you if necessary and remind you to take your medication on time. This method eliminates the need for patients to wait in line for appointments, encourages them to make healthy decisions, and frees up doctors' time to attend to more urgent situations.

Internet Search:

This probably tops the list when thinking about data science applications. And Google will probably tick the first box in your head when talking about internet searches. The fact, however, is that there are numerous other search engines like yahoo, AOL, Ask, Bing, and others, and all of them employ data science algorithms to provide quick and accurate search results. Google is known to handle over 20 petabytes of data per day, which translates into massive processing. Without data science, Google would not have existed as it does today.

Augmented Reality

Another significant data science application that seems most promising for the future is the domain of enhanced reality. Virtual reality and data science do have interaction. We may see this in the incorporation of algorithms, computer expertise, and data in virtual reality headsets in order to provide an optimal viewing experience. The immensely popular game Pokemon GO is a very little step in that direction. the ability to navigate obstacles while viewing Pokemon on buildings, streets, and other fictitious objects. The Pokemon and gym locations in this game were chosen using information from Ingress, the previous app from the same business.

Targeted Advertising

There is an assumption that search engines have been the most popular data science applications, while it extends beyond and covers entire digital marketing.  Starting from digital billboards to display banners on various websites, their selection is made based on data science algorithms. This explains why traditional commercials have a far lower Call-Through rate (CTR) than digital ads. They may be chosen based on a user's previous actions. This explains the reason for another person might be seeing a clothing ad while another might be seeing an educational training program ad like a Data science course in the same location. 

Website Recommendations

The benefits of data science applications are greatly seen in the numerous business merchants like Amazon, where we often see suggestions for products that we may like, based on our search history. This intervention not only aids in finding relevant items or products but also adds manifold to the user experience. Many businesses have fervently utilized this engine to market their goods in accordance with customer desire and informational relevancy. This technique is used to enhance the user experience by internet behemoths like Twitter, Google Play, Netflix, LinkedIn, Amazon, IMDb, and many others. The suggestions are generated based on a user's prior search results.
