To calculate the term of each loan and add a sixth column to the table, we'd need additional information that isn't provided in the image, such as the loan start date or total number of EMIs. Without this, we can't accurately determine the loan terms.


However, detailed notes on the content and purpose of  AI applications in finance:

  1. Title and Purpose:
  2. Use Case 1: EMI validation for hidden rescheduled advances to prevent NPA (Non-Performing Assets)
  3. This slide demonstrates how AI can be used to analyze loan data and potentially identify risky loans before they become NPAs.
  4. Data Structure:
  5. The table presents a sample input dataset with 10 loan entries.
  6. Columns include: Loan Amount, Interest Rate, Outstanding Amount, Sanction Date, and EMI Amount.
  7. Key Points for Discussion: a) Data Analysis in Finance:
  8. AI can process large volumes of loan data quickly and efficiently.
  9. It can identify patterns and anomalies that might be missed by human analysts.


b) Risk Management:

  1. By analyzing EMI amounts against loan parameters, AI can flag potentially problematic loans.
  2. This proactive approach can help prevent loans from becoming NPAs.


c) Rescheduled Advances:

  1. The title mentions "hidden rescheduled advances," suggesting AI's potential to uncover loans that have been restructured without proper documentation.


d) Variability in Loan Terms:

  1. Note the wide range of loan amounts (from 1,97,000 to 45,00,000) and interest rates (6% to 15.95%).
  2. Discuss how AI can handle such variability in loan parameters.


e) EMI Calculation:

  1. AI can verify if EMI amounts are consistent with loan terms, potentially identifying errors or fraud.


f) Time Series Analysis:

  1. The sanction dates span from 2007 to 2018, showing how AI can analyze trends over time.

4. AI Applications:

  1. Predictive modeling for loan default risk
  2. Anomaly detection in loan portfolios
  3. Process automation in loan approvals and monitoring
  4. Real-time risk assessment
