Data applications in Finance

Data Science applications in Finance was one of the earliest use of data science technologies in real-world applications. Since finance sectors also generate lots of data, they wished to do away with the traditional processes of paperwork. Data science algorithms have introduced innovative ways of analysing risk probabilities, by separating data using different variables like customer profiling, past expenditure, Annual Earnings and other variables. 

Data science algorithms also help different banks suggest their banking products to people based on their purchasing powers. It also helps to create a more personalized experience for each customer based on their user experience, modification of financial preferences etc. 

Even in Stock Market, data science application is very prominent. Using past data of different stocks and trends, they can predict what the future outcome will be like. This helps to analyze what the future prices of the stocks will be like across a set period. 

Advanced Image Recognition

Image recognition is another among the trending data science applications that have seen tremendous uses. Social Media applications like Facebook use this feature extensively. Suppose you are uploading a picture of your friends on Meta (previously Facebook). Soon you are bombarded with suggestions of whom you should be tagging in that photo. This is an example of data science integration. 

When an image is recognized by the algorithm, it analyses the picture and then analyses your friends on Meta. If any of the faces match with that in the picture, then they suggest the auto-tagging features. 

Apart from this, Google also enables image search facilities. Through this, you can upload an image on google and search for similar pictures. Google lens is another data science application that makes use of the Advanced Image recognition feature. 

Speech Recognition

Speech recognition is all the rage right now. Home-assistant speakers like Google Home, Amazon Alexa helps recognize the voice and implement actions based on that. Simply one of the most innovative applications among the new data science applications. Even voice assistants on mobile phones like Siri or Microsoft’s Cortana only gets better as they receive more data. From carrying out simple commands like giving answers to questions like “what is the weather like today?” to carrying out complicated commands like switching on or off your home security systems. 

Internet Search

Internet Search is probably the commonest example of the best data science applications. Internet is what revolutionised the world and made it more digitized. Google is the most famous search engine although there are many other popular search engines like Bing, Yahoo, AOL etc. without data science algorithms fused with the internet, the world would just not be the same. 

Targeted Advertising 

The digital world owes most of its fame to targeted advertising. The most unique feature of the data science algorithm is specificity. Data Science technologies help us to choose our specific customers online. For example, if I were to go on Google today and searched for a mobile phone online, I would see ads pertaining to mobile phones on different websites. Whether it be Facebook or YouTube, they both show ads based on the demographics of the audience or the viewer, whatever the case may be. 

Platforms like Google Ads and Facebook Marketing allows marketers to choose whom their advertisements would be shown to. Say if I am a matrimonial site that wishes to promote my services, then my ads would only be shown to singles in their late 20s to 40s or people who have expressed an interest in different matrimonial sites. 

Digital Marketing is no doubt one of the best data science applications.
