Artificial Intelligence (AI)
Definition: AI is a broad field of computer science focused on creating systems capable of performing tasks that would typically require human intelligence. These tasks include problem-solving, learning, reasoning, perception, and language understanding.
Scope:
- AI encompasses a wide range of technologies and methodologies.
- It includes various subfields like natural language processing (NLP), robotics, expert systems, and more.
Types:
- Narrow AI: AI systems designed to perform a specific task, such as voice recognition or image classification.
- General AI: Hypothetical AI that can perform any intellectual task that a human can do.
- Superintelligent AI: An AI that surpasses human intelligence across all fields (still theoretical).
Examples:
- Self-driving cars (using a combination of computer vision, decision-making, and control systems)
- Virtual personal assistants like Siri or Alexa
- Chess-playing programs like IBM's Deep Blue
Machine Learning (ML)
Definition: ML is a subset of AI that focuses on the development of algorithms and statistical models that enable computers to learn and make predictions or decisions based on data. The primary goal of ML is to allow systems to learn from experience without being explicitly programmed for every task.
Scope:
- ML is a narrower field within AI, specifically dealing with the design and development of algorithms that can identify patterns and make decisions with minimal human intervention.
- It heavily relies on data and statistical methods.
Types:
- Supervised Learning: The model is trained on labeled data (input-output pairs) to make predictions or classify data.
- Examples: Linear regression, support vector machines, neural networks.
- Unsupervised Learning: The model is trained on unlabeled data to find hidden patterns or intrinsic structures.
- Examples: Clustering algorithms (like K-means), principal component analysis (PCA).
- Reinforcement Learning: The model learns by interacting with its environment and receiving rewards or penalties.
- Examples: Q-learning, deep reinforcement learning.
Examples:
- Spam email filtering
- Product recommendation systems (like those used by Amazon or Netflix)
- Predictive maintenance in manufacturing
