Study Notes
- Artificial intelligence (AI) refers to the simulation of human intelligence in machines programmed to think and act like humans
- AI encompasses a broad range of techniques and approaches that aim to enable computers to perform tasks that typically require human intelligence
Machine Learning (ML)
- ML is a subset of AI that focuses on enabling systems to learn from data without being explicitly programmed
- ML algorithms allow computers to automatically learn and improve from experience
- Common types of ML include supervised learning, unsupervised learning, and reinforcement learning
Supervised Learning
- Supervised learning involves training a model on a labeled dataset, where the correct output is known for each input
- The model learns to map inputs to outputs based on the provided examples
- Common supervised learning tasks include classification and regression
Unsupervised Learning
- Unsupervised learning involves training a model on an unlabeled dataset, where the correct output is not known
- The model learns to find patterns and relationships in the data without explicit guidance
- Common unsupervised learning tasks include clustering and dimensionality reduction
Reinforcement Learning
- Reinforcement learning involves training an agent to make decisions in an environment to maximize a reward
- The agent learns through trial and error, receiving feedback in the form of rewards or penalties
- Reinforcement learning is commonly used in robotics, game playing, and control systems
Natural Language Processing (NLP)
- NLP is a field of AI that focuses on enabling computers to understand, interpret, and generate human language
- NLP techniques are used in a variety of applications, including machine translation, sentiment analysis, and chatbot development
Core NLP Tasks
- Tokenization: Splitting text into individual words or tokens
- Part-of-speech tagging: Identifying the grammatical role of each word in a sentence
- Named entity recognition: Identifying and classifying named entities, such as people, organizations, and locations
- Sentiment analysis: Determining the sentiment or emotion expressed in a text
- Machine translation: Translating text from one language to another
- Text summarization: Generating a concise summary of a longer text
Computer Vision
- Computer vision is a field of AI that focuses on enabling computers to "see" and interpret images and videos
- Computer vision techniques are used in a variety of applications, including object detection, image recognition, and image segmentation
Core Computer Vision Tasks
- Image classification: Assigning a label to an entire image
- Object detection: Identifying and locating objects within an image
- Image segmentation: Partitioning an image into multiple regions or segments
- Facial recognition: Identifying and verifying faces in an image or video
- Image generation: Creating new images from scratch or based on existing images
Ethics in AI
- Ethics in AI refers to the moral principles and values that should guide the development and deployment of AI systems
- As AI becomes more prevalent, it is crucial to address the ethical implications of its use, ensuring that AI systems are fair, transparent, and accountable
Key Ethical Considerations
- Bias: AI systems can perpetuate and amplify existing biases in data, leading to unfair or discriminatory outcomes
- Transparency: Understanding how AI systems make decisions can be difficult, raising concerns about accountability and trust
- Privacy: AI systems often require large amounts of data, which can compromise individuals' privacy
