About Machine Learning
Machine Learning for Finance involves using algorithms and statistical models to analyze financial data, detect patterns, and make predictions or decisions—often faster and more accurately than traditional financial models. It’s a fast-growing field in quantitative finance, fintech, asset management, and risk analysis.

Why Use Machine Learning in Finance?
Machine learning (ML) can:
Identify trading signals from historical data
Predict stock prices or credit defaults
Automate portfolio management (robo-advisors)
Detect fraud in real-time
Key ML Techniques Applied in Finance
Technique | Financial Use Case |
---|---|
Regression (Linear, Lasso, Ridge) | Forecast asset prices, estimate returns |
Classification (Logistic, Random Forest, SVM) | Predict loan defaults, credit risk, fraud detection |
Clustering (K-Means, DBSCAN) | Customer segmentation, market regime detection |
Natural Language Processing (NLP) | Sentiment analysis on news and earnings reports |
Time Series Models (ARIMA, LSTM) | Forecast stock prices, volatility |
