Study Notes
Handwritten Digit Classification
- Neural networks provide a novel approach to classifying handwritten digits by utilizing training examples.
- Increasing training examples enhances the network's ability to learn handwriting features.
- The problem is divided into two sub-problems: segmentation of images into separate digits and classifying each digit.
- The classification task will be addressed using a three-layer neural network.
Neural Network Performance
- A sweet spot for training epochs is typically between 5 to 7.
- Training for 15 or 20 epochs may lead to overfitting, impacting performance negatively.
AI in Finance
- Proficiency in computer programming is essential for careers in finance.
- Hedge funds, such as Two Sigma, increasingly prioritize candidates with programming skills over traditional traders.
- AI integration in trading roles transforms mathematicians and data analysts into modern traders.
- AI algorithms outperform human analysts in discovering new trading strategies and patterns.
AI Applications in Financial Services
- The financial sector is the largest investor in AI applications, experiencing rapid growth in integration.
- Common AI applications include:
- Algorithmic trading
- Portfolio composition and optimization
- Model validation
- Fraud detection
- Robo-advising
- Virtual customer assistance
- Market impact analysis
- Regulatory compliance and stress testing
Key Areas of AI Impact
- Major areas where AI is transforming finance include:
- Fraud detection and compliance
- Banking chatbots and robo-advisory services
- Algorithmic trading
Robo-Advisors and Chatbots
- Unit costs in financial intermediation have remained stable over 130 years, with little decline post-2008 financial crisis.
- Robo-advisors assist consumers with investment, banking, and insurance decisions using algorithm-based digital platforms.
- Chatbots streamline financial services by automating tasks and providing user-friendly interfaces.
Notable Examples of AI in Banking
- Plum: A Facebook Messenger chatbot that analyzes spending and savings to help users save money.
- JP Morgan's COiN: AI technology that reviews documents rapidly, achieving the equivalent of 360,000 human hours in seconds.
- Bank of America's Erica: An AI-driven chatbot available for assistance via voice or message.
Algorithmic Trading
- Also known as Automated Trading Systems, these systems apply trading rules into programmed algorithms.
- AI trading utilizes machine learning to identify data structures and make predictions about market movements.
