See how Banks can harness the power of machine learning for new age digital finance
With the rapid growth of data science in finance, many companies have been harnessing the strength of evolving technologies like machine learning (ML). It helps businesses gain valuable insights from raw data.
The quickly evolving Machine Learning (ML) models help companies stay up-to-date and meet consumer needs. Moreover, many business processes can easily access these using clouds.
The ML/AI in the Fintech market is expected to register a CAGR of 25.3% during the forecast period (2022 - 2027). Currently, we have reached a point where we can demand clarity on the ROI of ML/AI deployments and efforts for its adoption undertaken over the past few years.
What is Machine Learning (ML) Transforming for Banks?
Data lakes provide a centralized repository for data, and cloud computing, in turn, offers simplified accessibility to sophisticated computer applications needed to unlock the full potential of data lakes. Supporting both, Machine learning (ML) algorithms in lending processes drive actionable decisions from the vast amounts of data stored in data lakes, facilitated by the agility and computational power of the cloud.
By leveraging machine learning techniques, lenders can gain deeper insights into borrower behavior, automate loan underwriting processes, and enhance overall decision-making.
Let’s see all its benefits.
360° Vigilance in Credit Monitoring
It analyses and processes raw and unstructured data in split seconds. It identifies any uncertainty in a secure scenario and can also automatically detect data breaches and notify immediately. ML algorithms safeguard customer data, solidify the reputation of a company, and even prevent huge losses.
Machine learning algorithms play a crucial role in providing 360-degree vigilance in credit monitoring by continuously analyzing and detecting patterns in credit-related data. Some commonly used ML algorithms for credit monitoring include:
Random Forest: Random Forest is an ensemble learning algorithm that combines multiple decision trees to classify credit-related events. It can handle large datasets, identify relevant features, and provide accurate predictions, making it effective in detecting fraudulent activities and credit risks.
Gradient Boosting: Gradient Boosting is another ensemble learning technique that builds a series of weak prediction models to create a strong predictive model. It excels in handling imbalanced datasets and can identify subtle patterns or anomalies in credit data, enabling proactive monitoring of potential fraud or credit default risks.
Logistic Regression: Logistic Regression is a widely used algorithm for binary classification tasks in credit monitoring. It estimates the probability of credit-related events occurring based on various input variables. It can help identify high-risk transactions or behaviors that may indicate potential credit issues.
Neural Networks: Neural Networks, specifically deep learning models, are powerful tools for credit monitoring due to their ability to learn complex patterns and relationships within credit data. They can analyze multiple variables simultaneously and identify anomalies or fraudulent activities with high accuracy.
Support Vector Machines (SVM): SVM is a popular algorithm for credit monitoring that separates different classes of credit events by constructing hyperplanes in a high-dimensional feature space. It can effectively classify and identify credit risks by maximizing the margin between different classes.
Clustering Algorithms: Clustering algorithms, such as k-means or DBSCAN, can be used to group similar credit transactions or customer behaviors together. This helps identify clusters of transactions that deviate from normal patterns, indicating potential anomalies or fraudulent activities.
It's important to note that the choice of ML algorithms depends on the specific requirements of credit monitoring, the nature of the data, and the goals of the financial institution.
A combination of these algorithms, along with appropriate feature engineering and data preprocessing techniques, can provide comprehensive vigilance in credit monitoring to identify and mitigate potential risks.
Forecasting Demand More Accurately
To maintain a position in a rapidly growing and challenging market and to top it, the increasing customer demands, incorporating ML in Data Analytics, companies can gain more powerful capabilities for forecasting demand which gradually rakes in better profits.
Banks need to forecast several key demands to effectively manage their operations and make informed business decisions.
Machine learning aids banks in forecasting demand by analyzing vast amounts of historical and real-time data, identifying patterns and trends, and generating accurate predictions. These predictions enable banks to optimize resource allocation, make informed business decisions, and meet customer demands effectively.
Some of the demands that banks typically forecast include:
Loan Demand: Machine learning algorithms analyze historical loan data, economic indicators, and customer information to forecast future loan demand, helping banks optimize lending strategies and allocate capital effectively.
Deposit Demand: By leveraging machine learning, banks can analyze historical deposit patterns, customer behavior, and market conditions to forecast deposit demand, enabling effective liquidity management and tailored deposit product offerings.
Foreign Exchange (FX) Demand: Machine learning algorithms analyze historical currency exchange data, economic factors, and geopolitical events to forecast foreign exchange demand, enabling banks to optimize currency inventory and provide competitive rates to customers.
Investment and Wealth Management Demand: Through machine learning, banks can analyze customer preferences, market trends, and financial data to forecast demand for investment and wealth management products, facilitating personalized investment strategies and better client engagement.
Digital Banking and Payment Services Demand: Machine learning algorithms analyze customer behavior, transaction data, and digital engagement metrics to forecast demand for digital banking and payment services, enabling banks to enhance digital offerings and optimize user experiences.
Risk Management and Compliance Demand: Machine learning algorithms analyze historical data, regulatory requirements, and emerging risk factors to forecast demand for risk management and compliance solutions, helping banks ensure regulatory compliance and mitigate operational risks.
This enables banks to optimize resource allocation, personalize services, and make informed decisions in these areas.
