Study Notes

Research Areas in Artificial Intelligence

Expert Systems: Used in applications like flight-tracking and clinical systems for decision-making processes.
Natural Language Processing (NLP): Implements features like Google Now, speech recognition, and automatic voice output.
Neural Networks: Essential for pattern recognition tasks such as face, character, and handwriting recognition.
Robotics: Involves industrial robots for diverse tasks including moving, painting, cleaning, and drilling.
Fuzzy Logic Systems: Applied in consumer electronics and automotive industries for improved decision-making.

State of Art of AI

Ubiquity of AI: Integrated into daily life through devices such as washing machines, air conditioners, and smartphones.
Industry Advancements: Robots perform tasks in factories; developments in self-driving cars and AI-enabled toys like WiFi Barbie.
Business Applications: Companies utilize AI for product enhancement and sales growth.
Progress in Machine Learning: Significant advancements in Deep Learning, Emotional AI, IoT, and customer service applications.

Problem Solving with Artificial Intelligence

Problem-Solving Techniques: Involves algorithms, heuristics, and root cause analysis to determine optimal actions.
AI Search Process: Entails exploring various action sequences to find the most effective path to a solution.

Classic AI Search Problems

Rubik’s Cube Problem: A 3D puzzle aimed at aligning colors on each face.
N-Puzzle Problem: Various versions (8, 15, 24 tiles) involving reordering tiles in minimal moves on a grid.
Water Jug Problem: Involves finding the right quantities using two jugs of differing capacities.
N-Queen Problem: Arranging N queens on a chessboard so they do not threaten each other.

Search Algorithm Factors

Completeness: Assurance of finding a solution if one exists.
Optimality: Guarantee that the solution is the best among all possible options.
Time Complexity: Measure of the time required relative to problem complexity.

Measuring Problem-Solving Performance

Outcomes may include reaching a failure state, a solution state, or being stuck in an infinite loop.
Performance can be assessed based on completeness, optimality, time complexity, and space complexity.

Search Strategies

Uninformed Search: Also called blind search; uses only initial and goal states without additional information. Examples include:
- Breadth-First Search (BFS)
- Depth-First Search (DFS)
- Uniform Cost Search (UCS)
- Depth-Limited Search (DLS)
- Iterative Deepening DFS (IDDFS)
- Bi-directional Search
Informed Search (Heuristic Search): Utilizes additional information to direct the search process towards a goal efficiently. Can be either complete or incomplete, and generally faster than uninformed search.

Implementation of Search Strategies

Uninformed Search Characteristics: Time-consuming and expensive in space and implementation while ensuring completeness.
Informed Search Usefulness: Enhances search efficiency, reduces time and cost, and simplifies implementation process.
