Study Notes
Introduction to Artificial Intelligence (CPCS-335)
- Course: CPCS-335 Introduction to Artificial Intelligence
- Lecture: 8, Machine Learning Part (I): Introduction
- Instructor: Dr. Arwa Basbrain & Dr. Nofe Alganmi
Machine Learning (ML) introduction
- ML is a subset of AI focused on algorithm and statistical model development.
- Computers perform tasks without explicit programming.
- Computers learn from data.
- A computer program learns from experience (E) with respect to task (T) and performance measure (P). Performance on T, as measured by P, improves with experience.
Why use machine learning agents?
- Adapt to dynamic environments
- Improve performance
- Handle uncertainty
- Reduce human intervention
- Complex decision-making
- Generalization and transfer learning
- Handling large data
- Real-time decision-making
ML Applications
- Search engines
- Online shopping
- Entertainment (e.g., YouTube)
- Social media (e.g., Facebook)
- Smart assistants
- Navigation
- Banking
- Fraud detection
ML Pipeline: From Problem to Deployment
- Gathering data
- Preparing data
- Selecting & training the model
- Testing & deploying the model
Important Characteristics of Training Data
- Quality: Data must be accurate, unbiased, and relevant to the problem.
- Quantity: More training data generally leads to better model performance. Larger datasets offer more comprehensive representations of the scenario or problem to be solved.
Types of Machine Learning Models
- Supervised learning
- Unsupervised learning
- Reinforcement learning
Supervised Learning
- Labelled data: Data with known correct outputs.
- Classification: Sorting items into categories (e.g., cat vs. dog images).
- Regression: Identifying real values (e.g., house prices).
Unsupervised Learning
- Clustering: Grouping unlabeled data based on similarities or differences (e.g., customer segmentation).
- Dimensionality reduction: Reducing the number of features in a dataset (e.g., medical image analysis).
Reinforcement Learning
- Learning through interactions with the environment.
- Learning by trial and error based on feedback from the environment.
- Agent learns to make decisions to maximize a reward signal over time.
Examples of Learning Domains
- Classification: Fraud detection, email spam detection, diagnostics, image classification
- Regression: House price prediction, temperature forecasting, stock price prediction, healthcare cost prediction, energy consumption forecasting
- Clustering: Customer segmentation, image segmentation, social network analysis, document clustering, genomic data analysis.
- Reinforcement Learning: Finances, Manufacturing, Stock management, self-driving cars.
Machine Learning Main Components
- Data: The fuel for machine learning.
- Model: The core component of machine learning, gains knowledge from training data to make predictions on new, unseen data.
Data Sources
- Ecommerce
- Financial
- Environmental
- Transportation
- Healthcare
- Social Media
- Internet of Things
- Education
- Communication
