2. Risk Management

Risk management in banks has changed substantially in the last decade as new threats emerge. The regulations have also gone stricter post-global financial crisis. The adoption of data science is enabling new risk, management models. Machine learning technologies can identify complex, nonlinear patterns in large volumes of data and help create models with higher accuracy. These data models also self-learn with every bit of every data and pattern to improve their predictive power with time.

3. Customer Data Analysis

Banks are collecting large amounts of data from consumers. Analyzing these datasets is possible with data science technologies. Based on the information collected through social media, customer surveys and data from other touchpoints, the banks can understand customer sentiment NLP. Machine learning and data science can deconstruct these data sets easily and provide deep data intelligence on customers’ needs, wants and perceptions about the bank.
