Study Notes
Machine Learning Algorithms
- Supervised learning uses labeled data for training, allowing algorithms to make predictions based on input-output pairs, similar to teaching with examples.
- Unsupervised learning trains algorithms on unlabeled data, enabling them to discover patterns and relationships independently, akin to solving a puzzle without guidance.
- Reinforcement learning rewards correct decisions and penalizes errors, resembling training a pet—learning through trial and feedback.
- Each algorithm supports AI applications, from voice recognition to autonomous vehicles.
Deep Learning Techniques
- Deep learning utilizes sophisticated techniques, particularly neural networks, to enhance AI capabilities.
- Convolutional Neural Networks (CNNs) specialize in visual data processing, integral for image and video recognition by mimicking human visual processing.
- Recurrent Neural Networks (RNNs) excel with sequential data, effectively handling text and speech for tasks like language translation and sentiment analysis.
- CNNs and RNNs are foundational elements driving advancements in deep learning.
Programming Languages and Tools for AI Development
- Popular programming languages for AI development include Python, Java, and C++.
- Continuous skill enhancement and staying updated with technological advancements are vital for developers to navigate challenges in AI.
Interpretation of Results
- AI's increasing complexity raises challenges in interpreting results, leading to potential mistrust and skepticism towards technology.
- Deep learning algorithms, while effective, can obscure decision-making processes, complicating bias detection and correction.
- Autonomous vehicles present interpretability challenges, especially in the context of accidents, raising ethical issues related to safety and reliability.
- Addressing interpretability through transparency and explainability is crucial for responsible AI deployment.
Human Expertise in AI Development
- Human expertise is essential in AI development, particularly for knowledge acquisition.
- Knowledge bases contain domain knowledge needed for problem-solving, consisting of facts (widely accepted information) and heuristics (empirical and less strictly defined knowledge).
- Common knowledge acquisition methods include manual interviews, semi-automatic expert-driven approaches, and fully automatic methods.
Knowledge Representation
- Knowledge representation formalizes expert knowledge within computer programs, essential for acquiring, retrieving, and reasoning with knowledge.
- Important schemas for knowledge representation include production rules, frames, and semantic objects.
Production Rules
- Production rules, consisting of IF-THEN statements, model human behavior and allow for the conclusion of actions when conditions are met.
- Rules enable the derivation of new knowledge through combinations, serving as straightforward knowledge representations.
Advantages and Limitations of Production Rules
- Advantages include ease of understanding, simplicity in deriving inferences, and straightforward modifications.
- Limitations arise in complex knowledge areas needing multiple rules, search inefficiencies in systems with extensive rules, and difficulties in maintaining rule interdependencies.
Inference Mechanisms
- Inferencing examines knowledge bases to answer questions or solve problems, utilizing theorem provers, production systems, semantic networks, and description logic systems.
- In rule-based systems, inference engines operate through forward or backward chaining to execute relevant rules until goals are met.
Forward Chaining Systems
- Forward chaining systems activate rules based on current working memory facts, continuously updating the state based on rule specifications.
- The execution cycle involves matching rules, conflict resolution among matches, and executing the applicable rules until no more rules apply.
