Study Notes
Foundations of AI and Sub-areas of AI
- Explores five key areas of Artificial Intelligence (AI): Machine Learning, Expert Systems, Computer Vision, Natural Language Processing (NLP), and Robotics.
Machine Learning
- Focuses on algorithms that enable data-driven decisions.
- Employs computers to identify patterns and relationships in various data types (images, sounds, structured arrays).
- Uses mathematical models and algorithms.
- A critical tool in healthcare, finance, e-commerce, and robotics.
Types of Machine Learning
- Supervised Learning: Uses labeled datasets to train models and predict outcomes for new inputs.
- Unsupervised Learning: Works with unlabeled datasets to discover hidden patterns or anomalies used in customer segmentation, anomaly detection and data exploration.
- Semi-Supervised Learning: Combines labeled and unlabeled data, useful when labeled data is scarce.
- Reinforcement Learning: An agent learns to achieve objectives by interacting with an environment, improving decisions through trial and error, used in robotics and autonomous vehicles.
Expert Systems
- A human expert's decision-making ability is simulated using pre-programmed knowledge and logical rules.
- Provides advice or makes decisions in specific domains.
- Follows a fixed set of rules.
- Relevant where stability and rule-based logic are essential.
- Google's Nest home automation system is an example.
- Other examples include MYCIN (medical diagnosis), DENDRAL (chemical analysis), PXDES (lung diseases), and CADET (military planning).
Computer Vision
- Automates extraction, analysis, and interpretation of information from images/videos.
- Transforms visual data into numerical arrays to enable ML algorithms.
- Enables machines to "see" and understand the world in ways similar to humans.
- Advancements in algorithms (CNNs), GPU resources, distributed architectures, cloud computing, and data availability have made it possible.
- Self-driving cars and automated retail systems like Amazon Go are examples.
Natural Language Processing
- Enables machines to automatically process, analyze, and generate human language.
- Algorithms parse sentences by splitting them into words/letters or reading them left-to-right and right-to-left.
- Numerous use cases across industries: Named Entity Recognition (NER), Part-of-speech tagging, Reading comprehension, Machine translation, Text summarization, Spellcheck and autocomplete.
- Innovations in deep learning have made it faster and easier to train ML models on human language.
- Siri and Alexa are prime examples.
Robotics
- Branch of science designing, constructing, operating, and applying robots to solve problems and automate tasks.
- Robots range in forms and sizes.
- Robotics research has made tremendous strides in technology.
- Many robots have relied on expert systems. The robots of tomorrow integrate ML, CV, and NLP.
- Robots will be able to adapt and improve their performance and handle a wider variety of tasks, with the use of ML.
- With CV, robots will see and understand their environment, and with NLP, they will understand and process human language.
AI Applications
- AI in E-Commerce: Enhances customer experience and operational efficiency through personalized shopping, Al-powered assistants (chatbots), and fraud prevention.
- AI in Navigation: Enhances user experience by providing accurate, timely information.
- AI in Robotics: Al-powered robots can perform tasks like carrying goods in hospitals, cleaning offices, and managing inventory.
- AI in Human Resources: Simplifies the hiring process by analyzing resumes and profiles to filter candidates.
- AI in Healthcare: Utilized to build systems that can detect diseases and identify conditions, aiding in drug discovery.
- AI in Agriculture: Improves crop production and soil health, detects nutrient deficiencies and weeds.
- AI in Gaming: Creates smart, human-like non-playable characters (NPCs).
- AI in Automobiles: Key in self-driving vehicles and offers safety features.
- AI in Social Media: Enhances user experience, recommends posts, translates and filters content.
- AI in Marketing: Delivers targeted and personalized ads and aids in content marketing.
