Study Notes
Reinforcement Learning
- A machine learning technique that trains software to optimize decision-making through a trial-and-error learning process.
- Positive reinforcement increases the strength and frequency of behavior by associating it with favorable outcomes.
- Negative reinforcement strengthens behavior by removing or avoiding negative conditions.
- Policy determines actions based on the current state and rules set by the agent.
- Value function estimates the potential benefit of being in a specific state.
- A model can mimic the environment, predicting future states and rewards based on agent actions.
Deep Learning & Neural Networks
- Deep learning, a subset of machine learning, uses multilayered neural networks to simulate human decision-making.
- Neural networks operate similarly to biological neurons, processing inputs and arriving at conclusions.
- Applications of deep learning are prevalent in NLP, enhancing interactions in search engines, chatbots, GPS, and digital assistants.
- NLP combines computational linguistics with machine learning to enable computers to understand and generate human language, facilitating generative AI.
Computer Vision
- Field of AI focused on enabling systems to interpret and derive information from visual inputs.
- Human vision provides innate understanding of context, while machine learning mimics this perception using cameras and algorithms.
- Applications include:
- Autonomous vehicles using sensors for navigation.
- Identifying patterns and abnormalities in medical images, aiding in disease detection.
- AI in radiology optimizes workflows by prioritizing cases and speeding up diagnoses.
AI in Finance
- AI enhances fraud detection, algorithmic trading, and risk assessment within the finance sector.
- Fraud detection involves:
- Anomaly detection to identify unusual patterns in transactions.
- Predictive analysis to prevent potential fraud based on historical data.
- Enhanced security with strong protocols like biometric authentication.
- Algorithmic trading includes:
- Quantitative trading utilizing data models for large transactions.
- High-frequency trading that analyzes real-time data for rapid decision-making.
- Arbitrage trading to exploit price differences across markets.
- Risk assessment benefits from AI’s ability to analyze extensive customer data to accurately predict creditworthiness.
Bias & Fairness in AI Systems
- Bias in AI entails discrimination against individuals or groups based on attributes like race or gender.
- Fairness ensures equitable decision-making without disadvantaging any group.
- Sources of bias include:
- Data bias arising from non-representative training data.
- Algorithmic bias from inherent biases in design and implementation.
- Human bias introduced by developers.
- Types of bias include:
- Selection bias from non-representative training data.
- Measurement bias due to inaccuracies in data collection.
- Fairness can be viewed from frameworks like distributive fairness, which focuses on equitable resource distribution, and procedural fairness, which emphasizes unbiased decision-making processes.
