Study Notes

Artificial Intelligence (AI)

AI is a branch of computer science that aims to create computer systems capable of intelligent behavior
Defines intelligence as a combination of understanding natural language, knowledge acquisition and adaptation to scenarios, problem solving, common sense, and emotional empathy.
AI systems can be broadly categorized into two types: narrow (or weak) AI and general (or strong) AI

Turing Test

A test proposed by Alan Turing to evaluate a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human.
The test involves a human evaluator engaging in natural language conversations with both a human and a machine without knowing which is which.
If the evaluator cannot reliably distinguish the machine from the human based on their communication, the machine is said to have passed the test.

Knowledge Representation

AI systems need a way to store and utilize knowledge.
Several methods exist, including natural language, formal language, pictorial representations and graphical representation.
Natural language representations: Use human-readable text (e.g., paragraphs) to store knowledge.
Formal language representations: Use symbolic logic to represent knowledge precisely (e.g., if-then statements).
Pictorial representations: Use images and visual data to store knowledge.
Graphical representations: Use graphs to show relationships between concepts (e.g., semantic networks).

Division of Labor in AI

Computational tasks: These involve well-defined procedures and algorithms, such as calculations and sorting.
Recognition tasks: These tasks utilize sensory information; identifying patterns or objects (e.g., recognizing a person, recognizing speech).
Reasoning tasks: These tasks involve drawing conclusions using knowledge and reasoning based on existing knowledge.
- Reasoning is a crucial part of many human-level decision-making and problem-solving tasks.

Recognition Tasks

Neurological processes involving how humans process information are mimicked. Human brains contain about 86 billion neurons interconnected by synapses in a complex, massively parallel network. These neurons operate on a millisecond timescale, while computers operate on a nanosecond scale, affecting parallel processing capabilities.
Mimicking, a simplified representation of neurons and connections in the brain is attempted by using connectionist architectures, which are usually referred to as neural networks.

Reasoning Tasks

Intelligent searching: Algorithms efficiently search through large amounts of data to find desired solutions, including sequential search and binary search.
State-space search: A graph of different configurations of the problem is created to efficiently locate a solution.

Swarm Intelligence

Swarm intelligence: This is inspired by biological models, whereby the behavior of a group of simple agents (like ants, or birds) in a collective.
These simple agents collaborate to achieve complex goals.

Intelligent Agents

Intelligent agents: Agents are designed to interact with users in a helpful, proactive way; to perform tasks on behalf of a user and/or meet user requests.

Expert Systems

Expert systems: These systems mimic human expertise in a specific domain by storing rules and knowledge and using inference engines to reason through the rules to arrive at conclusions/solutions.

Robots

Robots: These devices can perform physical tasks, often by mimicking human capabilities
They receive sensory inputs and adjust their actions accordingly

Drones

Drones: These are Unmanned vehicles controlled by computers.
Drones are used for varied purposes such as surveillance, delivery, and aerial photography.

AI Milestones

Experts predicted AI milestones for various tasks in 2015, including language translation, LEGO assembly, driving trucks and surgery.
