     Data Science in FinTech: Roles, Use Cases, and Benefits

    Financial technology, popularly referred to as FinTech, is one of the fastest-growing areas of technological innovation and is popular with venture capitalists. FinTech refers to a set of technologies that focus on new ways of providing banking and financial services to consumers. When you use PayPal, Google Pay, or your credit card to pay online, you, the consumer, the e-commerce company, as well as the bank are all using FinTech to complete the transaction. Over time, FinTech has evolved to disrupt almost all aspects of financial services, including payments, investments, consumer finance, insurance, securities settlement, cryptocurrencies, etc.

    FinTech companies depend heavily on FinTech data science to simplify financial decision-making and deliver cutting-edge solutions. So first, let's see what data science in fintech is and its importance.

    What is Data Science?

    Data science is a field of study that combines industry expertise, programming skills, and knowledge of mathematics and statistics to extract meaningful insights from data. To perform tasks that normally require human intelligence. Data scientists apply machine learning algorithms to numbers, text, images, video, audio, and more to create artificial intelligence (AI) systems. These systems, in turn, generate insights that analysts and business users can translate into tangible business value. Want to learn more about Data Science in FinTech?

    Why is Data Science So Important?

    Data is not useful until it is transformed into valuable information. Mining large datasets containing structured and unstructured data and identifying hidden patterns to gain actionable insights are two main tasks in data science. The importance and application of Data Science lie in its tremendous uses, from everyday activities such as asking Siri or Alexa for recommendations to more complex applications such as controlling self-driving vehicles or robots.

    Organizations can also measure, track, and record performance metrics to facilitate decision-making across the enterprise. Businesses can analyze trends and make key decisions to retain customers, improve performance, and increase profitability. Data science models use historical data and can predict future actions. This helps organizations find ways to achieve the best business outcomes. Data science helps organizations identify and refine audiences by combining existing data with other data points to generate actionable insights. Data science also helps recruiters combine data points to identify the best candidate for the company's needs.

    Role of Big Data in FinTech

    we now live in an era that is unprecedented due to the amount of data around us, most of which is new. Here are some statistics to illustrate my point

    • 9 million emails sent per second;
    • 95 hours of video uploaded per minute to YouTube;
    • 500 million tweets per day;
    • 700 billion minutes/month spent on Facebook;
    • 40,000 queries per second (equivalent to 1.2 trillion searches per year) made on Google;
    • 9 million products ordered on Amazon per second; and
    • 3 exabytes of data sent or received by mobile devices/month (expected to increase to 30.5 exabytes/month by 2020).

    In case if you want to know 1 exabyte = 1 billion gigabytes. To put this in perspective, it is estimated that the entire contents of books printed ever hold 10 terabytes of data in all printed materials. Recent estimates of the size, including audio, video, and digital materials, start at 3 to 20 petabytes. So, one exabyte could hold 100,000 times the printed material, or 500 to 3,000 times the entire contents of the books printed, and we produce 3.3 exabytes of data every month!

    The best companies in FinTech are all trying to capture, measure, and draw insights from all the data that is around us now, even though it may be different information – some may even label it as “noise”.

    Even more exciting from our perspective, there are some very savvy entrepreneurs who are trying to build entirely new information services businesses out of data using FinTech data science that they can capture, manage and draw insights from. Check out what FiscalNote, DataFox, and ThinkNum, among others, are doing. (I daresay their products will blow a lot of people's minds.) There are many factors driving the “Big Data” (or what we call “information services”) opportunity within FinTech but let me focus on just two. First, there has been a big bang moment of newly available data sets, when almost all information, including financial transactions, is moving online. Second, advances in technology now allow machines (i.e., computer code) to replicate and increasingly even replace much of the work historically performed by human analysts (both the most demanding and well-paid analysts).

    I believe there is a great opportunity to create value for companies that can automate the collection of relevant data (through tools such as natural language processing) and deliver actionable insights drawn from data using data science, artificial intelligence, and advanced visualization capabilities so due to the complexity of this jobs, companies pay FinTech data scientist massive amount salary.

    In the financial industry, there is an increasing emphasis on big data and the possibilities hidden in it. Big Data, due to its technological foundation, has profit-generating opportunities and challenges, especially for the FinTech sector, and we are only at the beginning of what can create such a large amount of consumer and transactional data. Big Data is empowering innovators to advance hundreds of digital, technology, and internet industries, creating new sources of profit, better customer experiences, and new technologies that shape the way we live. Big Data in FinTech has helped incubate the industry, and as it continues to expand, we will face new challenges and opportunities.

    How Data Science is Used in FinTech

    4. Credit card Fraud detection

    Machine learning models can recognize unusual credit card transactions and fraud. The first and most important step involves collecting the raw data and then cleaning it (Removing unwanted characters and making it readable) one in all making it more structured and sorted, which is then used to train the model to predict the probability of fraud. Below are the steps involved in detecting fraud in credit card transactions:

    Classifying whether credit card transactions are authentic or fraudulent using algorithms such as logistic regression, random forests, support vector machines (SVMs), and many more

    • Predicting whether it is the cardholders or the fraudsters using the credit cards through credit card profiling
    • Using outlier detection methods to identify considerably different transactions (or 'outliers') from regular credit card transactions to detect credit card fraud.

    Machine learning (ML) models are more effective than conventional fraud detection models. They can recognize thousands of patterns from large datasets. ML offers insight into how users behave by understanding their app usage, payments, and transaction methods

    5. Predicting which customers will use international cards in upcoming months

    Using historical customer data such as travel history and spending on a card, a machine learning algorithm can predict which customers will likely use international cards in the upcoming months. This information will help companies to provide personalized offers to customers so that they can increase their revenue.
