- Super AI: Hypothetical AI that surpasses human intelligence and capabilities
Based on Functionality
- Reactive Machines: Basic AI systems that respond to specific inputs with specific outputs
- Limited Memory: AI that can learn from historical data to make decisions
- Theory of Mind: Advanced AI that understands human emotions and beliefs
- Self-Aware AI: Hypothetical AI with consciousness and self-awareness
Machine Learning Fundamentals
Machine Learning is a subset of AI that enables systems to learn and improve from experience without being explicitly programmed. It focuses on the development of computer programs that can access data and use it to learn for themselves.
Supervised Learning
The algorithm learns from labeled training data, helping to predict outcomes for unforeseen data. Common applications include:
- Image classification
- Spam detection
- Predictive analytics
- Risk assessment
Unsupervised Learning
The algorithm studies data to identify patterns without any predefined labels. Common applications include:
- Customer segmentation
- Anomaly detection
- Association mining
- Dimensionality reduction
Neural Networks
Neural networks are computing systems inspired by the human brain that can recognize underlying relationships in a set of data through a process that mimics how the human brain operates.
- Input, hidden, and output layers
- Weights and biases
- Activation functions
- Backpropagation
