Let us look at the agenda for this blog on Data Science in finance industry:

Why should we use Data Science in finance?

With the increase in digitization and online transactions, the risks of online fraud have increased rapidly. This is due to customer data leakage as there might be glitches in online transactions. As customer data is an invaluable resource in this digital era, we need to protect it from fraudsters. This is where Machine Learning and Data Science in finance help, preventing customers as well as organizations from financial losses. Let us understand the uses of Data Science in finance with the help of a use case.

Let us suppose that a customer has an account in Citibank. The bank collects customer’s data comprising transactions, loans, debits, credits, online shopping, and many more. The software used by the bank keeps track of each and every activity of the customer’s account.

After collecting the data, it analyzes the transaction history, transaction amounts, the frequency of transactions, and many other factors. Also, the security software used by the bank records the time and location of the transactions through Data Science techniques. The system flags a transaction if any unusual activity is found such as transactions made from two different locations at the same time.

Moreover, the bank evaluates its potential customers by their account balances. If a huge amount is credited or debited from an account, then the system marks the transaction as suspicious and checks for its validation. Further, on the basis of customer data analysis, the bank decides to give loans, offers, and other benefits to the customers. This helps in making cordial relations with potential customers. This also enhances its revenue generation.

All this is only possible with the involvement of Data Science in the finance industry. Now, we will go through some of the applications of Data Science in the finance industry.

Financial Fraud Detection

In the digital era, there is a rapid increase in online transactions. Along with this comes several unethical activities all over. For instance, there are cases of false insurance claims that have led to great losses in the financial sector. To deal with such critical problems, financial institutions have started deploying various technologies. One of those technologies is Data Science. The tools of Data Science are integrated with the business software to keep track of customer transactions and their past history.

Financial Fraud Detection

With the help of Data Science in finance, the security systems of financial institutions have become extremely secur and productive. Also, there is a decrease in credit card fraud in comparison to the financial history of the last 5 years. The algorithms of the software are designed in such a way that the software tries to learn from past data. Then, it uses its learning experience to predict the risks that may occur in the future. By this, Data Science helps financial companies from degrading.

Personalized Services

Personalized services are a key feature in today’s business world. The involvement of new technologies in customer services has made it possible to boost the overall growth of any business organization. These services use Data Science and Machine Learning for building applications that provide a personalized experience to customers. This has proved to be effective for financial institutions as well.

Personalized Services

Let’s consider the working of a bank. With the help of Data Science, the bank application analyzes customers’ data such as:

  • Frequent transactions
  • Shopping history
  • Debits/credits
  • Repaying of loans
  • Bank balance

There can be more hidden factors for evaluating customer data. With the help of this evaluation, the application provides a credit score for each customer. Based on the credit score, the bank identifies its profit-generating customers. Then, it provides offers, discounts, loans, and policies that can be beneficial for these customers.

Also, with Machine Learning and AI-based chatbots, customer services have improved a lot. In most of the areas of the financial industry such as insurance companies, loan providers, trading companies, banks, etc. use chatbots to provide high-quality customer service. Nowadays, these firms have also started using speech recognition technology to improve interactivity with customers. All these applications of Artificial Intelligence and Data Science in finance are helping businesses generate high profits.

Automation of Risk Management

Every business involves some risks that may ruin business profits. The digital era has come up with a lot of advanced technologies that can save any business from unnecessary losses. One of the advanced technologies used by most of the financial organizations is automation. The automation of tasks and business processes is possible with the help of Data Science and Machine Learning. In the finance industry, they are used for the automation of risk management.

Risk management is a crucial business activity that helps in analyzing faults in a business. To prevent the faults and inconsistencies in the business, the software for security systems analyzes data and tries to detect unusual patterns using Data Science. Also, with the help of Machine Learning algorithms, the software learns and improves itself for the better prevention of faults in the future. In the case of a financial firm, if any risk is involved in a financial activity, then the software notifies and blocks the activity for security reasons.

With the help of the application of Data Science in finance, the automation of risk management has become much more efficient, and this has led the organizations to have great improvement in business management and growth.

Credit Allocation

Machine learning (ML) plays a crucial role in credit allocation by providing banks and financial institutions with powerful tools to make more accurate and efficient lending decisions. ML algorithms can analyze vast amounts of data, including credit history, income, employment status, and other relevant factors, to assess the creditworthiness of borrowers.

ML models can identify patterns and correlations within the data, enabling lenders to make predictions about the likelihood of repayment and default. These models can be trained on historical data to learn from past loan outcomes and develop predictive capabilities.

By leveraging ML, lenders can automate and streamline the credit allocation process. This allows for faster decision-making, reduced human bias, and improved risk assessment. ML algorithms can also adapt and update their models in real-time, incorporating new data and adjusting lending strategies accordingly.

Overall, ML in credit allocation helps financial institutions make more informed and objective lending decisions, leading to improved loan approval rates, reduced defaults, and enhanced profitability.
