Data Science in Banking

Here are 6 interesting data science applications for banking which will guide you how data science is transforming banking industry.

1. Risk Modeling

Risk Modeling a high priority for the banking industry. It helps them to formulate new strategies for assessing their performance. Credit Risk Modeling is one of its most important aspects. Credit Risk Modeling allows banks to analyze how their loan will be repaid.

In credit risks, there is a chance of the borrower not being able to repay the loan. There are many factors in credit risk that makes it a complex task for the banks.

With Risk Modeling, banks are able to analyze the default rate and develop strategies to reinforce their lending schemes. With the help of Big Data and Data Science, banking industries are able to analyze and classify defaulters before sanctioning loan in a high-risk scenario.

Risk Modeling also applies to the overall functioning of the bank where analytical tools used to quantify the performance of the banks and also keep a track of their performance.

2. Fraud Detection

Technology is evolving rapidly!

With the advancements in machine learning, it has become easier for companies to detect frauds and irregularities in transactional patterns. Fraud detection involves monitoring and analysis of the user activity to find any usual or malicious pattern.

With the increase in dependency on the internet and e-commerce for transactions, the number of frauds has increased significantly.

Fraud Detection Process in data science

Using data science, industries can leverage the power of machine learning and predictive analytics to create clustering tools that will help to recognize various trends and patterns in the fraud-detection ecosystem.

There are various algorithms like K-means clustering, SVM that is helpful in building the platform for recognizing patterns of unusual activities and transactions. The process of Fraud Detection involves –

  • Obtaining the data samples for training the model.
  • Training our model on the given datasets. The process of training involves the implementation of several machine learning algorithms for feature selection and further classification.
  • Testing and Deploying our model.

For instance, two algorithms like K-means clustering and SVM can be used for data-preprocessing and classification. K-means can be used for feature selection and SVMs are then applied to the data for its classification into a fraudulent class or otherwise.

3. Customer Lifetime Value

Customers are an essential part of the banking industries. They ensure a steady stream of revenues. Formally speaking, a Customer Lifetime Value offers a discounted value of the future revenues that are contributed by the customer. Banks are often required to predict future revenues based on past ones.

Also, banks want to know the retention of customers and if they will help to generate revenues in the future as well. Banks want their customers to be satisfied and nurture them for the current as well as future prospects.

Businesses like banking sectors are required to predict their customer lifetime value. Data Science in banking plays an essential role in this part.

With predictive analytics, banks can classify potential customers and assign them with significant future value in order to invest company resources on them. While the classification algorithms help the banks to acquire potential customers, retaining them is another challenging task.

With the growth in the competition, banks require a comprehensive view of the customers to channel their resources in an optimized manner.

There are various tools that are used in data preprocessing, cleaning and prediction. There are various tools such as Classification and Regression Trees (CART), Generalized Linear Models (GLM), etc.

This allows the banks to monitor their customers and contribute towards the growth and profitability of the company.

4. Customer Segmentation

In customer segmentation, banks group their customers based on their behavior and common characteristics in order to address them appropriately.

In this scenario, machine learning techniques like classification and clustering play a major role in determining potential customers as well as segmenting customers based on their common behaviours.

One popular clustering technique is K-means, that is widely used for clustering similar data points.

It is an unsupervised learning algorithm, meaning that the data on which it is applied does not have any labels and does not possess an input-output mapping. Some of the various ways in which customer segmentation helps the banking institutions are –

  • Identification of customers based on their profitability.
  • Segmenting customers based on their usage of banking services.
  • Strengthening relationships with their customers.
  • Providing appropriate schemes and services that appeal to specific customers.
  • Analyzing customer segments to implement and improve services.

5. Recommendation Engines

Providing customized experiences to clients is one of the major roles that a bank plays. Based on customer transactions and personal information to suggest offers and extended services.

Banks also estimate what products the customer may be interested in buying after analyzing historical purchases. With this, banks will be able to recommend the product of the companies that have tied up with them.

It also recommends customer centric or product-centric offering based on their preferences. Banks can also recommend offers that are highly appealing to customers. There are two types of recommendation engines that are used by the banks –

  • User-Based Collaborative Filtering
  • Item-Based Collaborative Filtering

6. Real-Time Predictive Analytics

Predictive Analytics is the process of using computational techniques to predict future events. Machine Learning is the main toolbox of predictive analytics. Machine Learning is an ideal tool for improving the analytical strategy of the banks.

With the rapid increase in data, there is an abundance of use cases and the exigency of analyzing data is at its peak.

There are two types of major analytics techniques –

  • Real-time analytics
  • Predictive analytics

Real-time analytics allows customers to understand problems that impede businesses. Predictive Analytics, on the other hand, allow the customers to select the right technique to solve the problems.

There are areas like financial management of banking sectors that allow the industries to manage the finances and devise new strategies.
