Machine Learning in Finance

Machine Learning in Finance is a specialized application of artificial intelligence that uses algorithms to analyze vast amounts of financial data, identify patterns, and make predictions with minimal human intervention. This field powers a wide range of critical functions, including algorithmic trading to predict market movements, real-time fraud detection to secure transactions, and sophisticated credit scoring models to assess lending risk. By leveraging historical data and complex variables, ML enables financial institutions to automate decision-making, manage risk more effectively, and develop personalized financial products, ultimately aiming to increase efficiency, accuracy, and profitability in the financial sector.
