Study Notes
Automatic Systems
- Automatic systems are used for various tasks, including stock trading, image recognition, temperature control, and traffic control.
Breadth-First Search Time Complexity
- The time complexity of a breadth-first search algorithm is O(V + E) where V is the number of vertices and E is the number of edges in the graph.
Subjective Probabilities and Risk Assessment
- Subjective probabilities are used in risk assessment to account for an individual's beliefs, opinions, and experiences about the likelihood and consequences of potential risks.
Minmax Search Tie Situations
- In a minmax search, tie situations are handled by selecting the move that leads to the lowest score for the player and the highest score for the opponent.
Defuzzification Process
- Defuzzification is the process of transforming fuzzy output values into precise values within the context of fuzzy logic.
Iterative Deepening and Depth-First Search
- The main disadvantage of using iterative deepening compared to a depth-first search algorithm is that it requires more computation time to search the tree.
Dempster-Shafer Theory - Belief Function
- In Dempster-Shafer theory, the "belief function" represents the degree of belief that an event will occur.
Bayes' Theorem
- Bayes' theorem is represented by the formula: P(A|B) = P(B|A) * P(A) / P(B).
Probability of Equally Likely Outcomes
- If there are 10 equally likely outcomes, the probability of any one of them occurring is 10%.
Binary Cost Matrix - Predicting Positive Class
- In a binary cost matrix, the cost of predicting the positive class when the actual class is negative is called the "false positive cost".
LEXMED Features
- LEXMED is a system that does NOT provide medical diagnosis assistance.
Closed Formula in First-Order Predicate Logic
- A closed formula in first-order predicate logic is a formula that contains only closed terms, meaning all variables are bound by quantifiers.
Greedy Search Algorithms
- Greedy search algorithms are NOT optimal, meaning they may not always find the best solution.
Depth-First Search Time Complexity
- The time complexity of a depth-first search algorithm in terms of the number of nodes, n, and the number of edges, m, is O(n + m).
Supervised Learning Evaluation Metrics
- Common evaluation metrics in supervised learning include mean squared error, accuracy, recall, and precision.
Probability of a Certain Event
- The probability of an event occurring if it is certain to happen is 100%.
Heuristic Search Algorithms
- The primary disadvantage of heuristic search algorithms is that they may not find the optimal solution.
LEXMED Access
- Medical professionals typically access LEXMED through a web browser.
Bayes' Theorem Representation
- "P(A|B)" in Bayes' theorem represents the probability of event A occurring given that event B has occurred.
Maximum Entropy Without Constraints
- Maximum entropy without explicit constraints can make a lot of assumptions about the data.
Inference Rule in Uncertain Knowledge
- Modus tollens is a valid inference rule that allows you to infer the truth of a statement based on the falsehood of another statement and the truth of a third statement.
Bayes' Theorem Application
- Bayes' theorem is used to calculate the probability of an event occurring based on previous events.
Cost Matrix in Machine Learning
- A cost matrix in machine learning represents the cost of making predictions.
Risk Mitigation Methods
- Common methods of mitigating risks include transferring the risk to another party, accepting the risk, and reducing the likelihood of the risk occurring.
Breadth-First Search Space Complexity
- The space complexity of a breadth-first search algorithm in terms of the number of vertices, V, and the number of edges, E, is O(V + E).
Binary Cost Matrix - Rows and Columns
- A binary cost matrix has 2 rows and 2 columns.
Maximum Entropy Without Constraints
- Maximum entropy without explicit constraints is a statistical model that makes the least amount of assumptions about the data.
Principle of Maximum Entropy - True Statements
- All of the statements about the principle of maximum entropy are true:
- It assumes that the system is in a state of maximum disorder.
- It can be used to predict the probability of different outcomes in a system.
- It is used to predict the behavior of a system in equilibrium.
Dempster-Shafer Theory - Field of Application
- Dempster-Shafer theory is frequently used in the field of Artificial Intelligence.
Probability of Neither Event Occurring
- If the probability of event A occurring is 0.5 and the probability of event B occurring is 0.5, then the probability of neither event A nor B occurring is 0.25.
Purpose of Fuzzy Logic in Control Systems
- Fuzzy logic is used in control systems to provide imprecise, approximate control over system variables.
Depth-First Search Problems
- Depth-first search is useful for solving problems like determining if a graph is bipartite.
Probability of Neither Event Occurring (2)
- If the probability of event A occurring is 0.6 and the probability of event B occurring is 0.4, then the probability of neither event A nor B occurring is 0.
Binary Cost Matrix - Predicting Negative Class
- In a binary cost matrix, the cost of predicting the negative class when the actual class is positive is called the "false negative cost".
Dempster-Shafer Theory - Combination Rule
- The combination rule in Dempster-Shafer theory is used to combine the beliefs and plausibilities of multiple events.
Gödel's Incompleteness Theorems - Computer Science Influence
- Gödel's incompleteness theorems have NOT led to the abandonment of the use of computers.
Principle of Maximum Entropy - Maximum Ignorance
- The principle of maximum entropy is a special case of the principle of maximum ignorance.
Dempster-Shafer Theory - Plausibility Function
- In Dempster-Shafer theory, the "plausibility function" represents the level of uncertainty about an event.
Gödel's Incompleteness Theorems - Formal System Criteria
- Gödel's incompleteness theorems apply to a formal system if it is consistent, complete, and sound.
Gödel's Incompleteness Theorems - Computer Science Influence
- While Gödel's Incompleteness Theorems showed there are limits to what can be proven in formal systems, it has NOT led to the abandonment of the use of computers. It's spurred debate about limitations of computation and led to development of new algorithms.
