Study Notes
AI Fundamentals
- AI can be categorized into two programming approaches: rule-based programming, which uses pre-defined rules to make decisions, and data-driven programming, which relies on data to make predictions or classifications.
Types of AI
- Machine Learning: a type of AI that enables machines to learn from data without being explicitly programmed.
- Narrow AI (Weak AI): designed to perform a specific task, such as facial recognition or language translation.
- General AI (Strong AI): aims to mimic human intelligence, with the ability to reason, learn, and apply knowledge across a wide range of tasks.
Types of Machine Learning
- Supervised Learning: the machine is trained on labeled data to learn the relationship between input and output.
- Unsupervised Learning: the machine is trained on unlabeled data to discover patterns or structure.
- Reinforcement Learning: the machine learns through trial and error, receiving rewards or penalties for its actions.
- Semi-Supervised Learning: a combination of supervised and unsupervised learning, where the machine is trained on both labeled and unlabeled data.
AI Lifecycle
- Defining the problem: identifying the problem or opportunity that the AI model will address.
- Preparing Data: collecting, cleaning, and preprocessing the data for training.
- Training: using the prepared data to train the AI model.
- Testing: evaluating the performance of the trained model on a separate dataset.
- Evaluating the Model: assessing the model's performance and making adjustments as needed.
Machine Learning: Data Preparation
- Cleaning: removing duplicates, handling missing data, and correcting invalid data to ensure the data is reliable and consistent.
Machine Learning: Testing
- Testing for Bias: ensuring the model is fair and unbiased in its predictions or classifications.
- Measuring Accuracy and Confidence: evaluating the model's performance using metrics such as accuracy, precision, and recall.
Machine Learning: Confidence and Accuracy
- Bias in, Bias out: the model's performance is only as good as the data it's trained on, so biased data can lead to biased models.
- Decision Trees: a type of machine learning model that uses a tree-like structure to classify data and make predictions.
Decision Trees
- How decision trees are made: by recursively partitioning the data into smaller subsets based on the values of the input features.
Solving Problems with ML Models
- ML models can be used to solve a wide range of problems, from image and speech recognition to natural language processing and recommender systems.
