Underlying Assumptions in Artificial Intelligence Quiz and Flashcards

Artificial Intelligence

Artificial intelligence (AI) refers to machines mimicking human cognitive functions such as learning, problem solving, perception, reasoning, and self-correction. Often associated with machine learning and deep learning, it relies on algorithms that enable computers to understand and act based on data. Let's delve into the history, concepts, current trends, applications, and challenges surrounding AI.

Concept of AI

The concept of artificial intelligence has been around since the mid-1950s when computer scientists started exploring ways to create intelligent robots. John McCarthy, Marvin Minsky, Nathaniel Rochester, and Claude Shannon coined the term "artificial intelligence" during the Dartmouth conference in 1956. Since then, several approaches have been developed to achieve AI, including symbolic AI, connectionism, evolutionary computation, fuzzy systems, and expert systems.

History of AI

Early work on AI was driven by the belief that human intelligence could be emulated through programming. This led to the development of rule-based systems like ELIZA and MYCIN, which were capable of understanding natural language input and providing responses based on predefined rules. However, these systems faced numerous limitations due to their inability to learn from experience or deal with complicated tasks.

In 1980, George Forsyth introduced the concept of object recognition using neural networks, which helped pave the way for more sophisticated AI techniques. Later developments included reinforcement learning, support vector machines, gradient boosting, random forests, and deep learning models. Today, AI technology continues to evolve rapidly, with advancements in areas like autonomous vehicles, voice assistants, healthcare diagnosis tools, and financial market prediction models.

Current Trends in AI and AI Applications

Currently, there are three main branches of AI: narrow or weak AI, general or strong AI, and superintelligent AI. Narrow AI is designed for specific tasks, while general AI can handle various activities. Superintelligent AI would surpass human capabilities, potentially leading to new forms of governance and societal structures.

Applications of AI have expanded across industries, with notable examples being:

Healthcare: Diagnostic tools powered by AI help doctors identify diseases earlier and more accurately.
Finance: Predictive models aid investment strategies and risk management.
Education: Personalized learning platforms utilize AI to cater to student needs effectively.
Manufacturing: Smart factory processes employ AI to optimize production efficiency and reduce waste.
Transportation: Self-driving cars rely on AI technologies for navigation and safety features.

Human Vs Machine

Despite its potential benefits, AI also raises concerns regarding job displacement, privacy invasion, cybersecurity risks, ethical dilemmas, lack of transparency, and misinterpretation of context. Moreover, humans still excel in tasks requiring creativity, critical thinking, emotional intelligence, and physical abilities beyond robotic manipulation. Thus, collaboration between humans and AI may represent the future of work rather than a competition for jobs.

List of Intelligent Systems Influential in AI

Several intelligent systems have significantly influenced the development of AI technology:

ELIZA: A rule-based system that understood natural language input.
MYCIN: A rule-based system that advised medical diagnoses.
AlphaGo: A deep learning model that mastered the game of Go.
AlphaZero: A deep reinforcement learning model that taught itself to play various games from scratch.
AlphaFold: A deep learning model that predicted protein structures with remarkable accuracy.

AI Problem and Underlying Assumption

The biggest challenge in AI is the lack of understanding of human intelligence and the complexity of creating machines that can truly mimic it. Assumptions underlying AI development include:

Human intelligence can be characterized as symbolic processing.
Machines can learn from experience.
Intelligence can be measured and compared.
Computing power will continue to grow exponentially.

What is an AI Technique?

An AI technique is a method or approach used to develop intelligent systems. Some common AI techniques include:

Symbolic AI: Uses rules and logic to represent knowledge and solve problems.
Connectionism: Based on neural networks, it models patterns in data.
Evolutionary Computation: Involves algorithms inspired by biological evolution.
Fuzzy Systems: Handle uncertainty by approximating human decision-making.
Expert Systems: Capture expertise of human experts for problem-solving.
Machine Learning: Algorithms enable machines to learn from data.
Deep Learning: A subset of machine learning, it models complex patterns in data.

Level of the Model

AI models can be classified into different levels based on their complexity and performance:

Level 0 - Zero Intelligence: Basic predefined rules and logic.
Level 1 - Reactive Machines: Capable of responding to specific situations.
Level 2 - Limited Memory: Can remember past events and use that memory to inform future actions.
Level 3 - Learning: Can learn from experience and adapt to new situations.
Level 4 - Reasoning: Can reason about its actions and learn from explanations.
Level 5 - Self-Aware: Highly intelligent systems capable of self-awareness and consciousness.

Criteria for Success and General References to AI Work

Success criteria for AI systems include:

Efficiency: Minimizing computational resources.
