Intelligent Systems

What are Intelligent Systems?

Intelligent System is AI technology that consists of the capability to gather data, process it, and make decisions or perform actions based on that data. In precise, intelligent systems help in replicating human tasks like learning from experiences, understanding concepts, solving problems and making decisions.

Some of the characteristics of intelligent systems include −

• Autonomy: Many intelligent systems can operate independently or with minimum or no human intervention, making decisions based on learned experiences and programming.
• Learning Capability: These intelligent systems can improve themselves through time, by adapting new data and learning from feedback.
• Data Processing: Intelligent systems can handle large volumes of data to identify patterns and gain insights for making informed decisions, often using algorithms.
• Reasoning and Problem Solving: Intelligent systems can perform complex reasoning tasks, analyze scenarios, and offer solutions to specific problems.
• Human Interaction: Many intelligent systems are designed to interact with humans, through chatbots, voice assistants and robots.

Types of Intelligence

As described by Howard Gardner, an American developmental psychologist, following are the type of intelligence −

Intelligence	Description	Example
Linguistic intelligence	The ability to speak, recognize, and use mechanisms of phonology (speech sounds), syntax (grammar), and semantics (meaning).	Narrators, Orators
Musical intelligence	The ability to create, communicate with, and understand meanings made of sound, understanding of pitch, rhythm.	Musicians, Singers, Composers
Logical-mathematical intelligence	The ability to use and understand relationships in the absence of action or objects. Understanding complex and abstract ideas.	Mathematicians, Scientists
Spatial intelligence	The ability to perceive visual or spatial information and re-creating visual images without reference to the objects, construct 3D images, and to move and rotate them.	Map readers, Astronauts, Physicists
Bodily-Kinesthetic intelligence	The ability to use complete or part of the body to solve problems or fashion products, control over fine and coarse motor skills, and manipulate the objects.	Players, Dancers
Intra-personal intelligence	The ability to distinguish among one's own feelings, intentions, and motivations.	Gautam Buddhha
Interpersonal intelligence	The ability to recognize and make distinctions among other people's feelings, beliefs, and intentions.	Mass Communicators, Interviewers

You can say a machine or a system is artificially intelligent when it is equipped with at least one and at most all intelligence in it.

Components of Intelligence

The components of intelligence collectively define and influence the capabilities and performance of replicating human intelligence. The core components of intelligence are −

• Reasoning − It is the set of processes that enables us to provide a basis for judgement, making decisions, and prediction.
• Learning − It is the activity of gaining knowledge or skill by studying, practicing, being taught, or experiencing something. Learning enhances the awareness of the subjects of the study. The ability of learning is possessed by humans, some animals, and AI-enabled systems.
• Problem Solving − It is the process in which one perceives and tries to arrive at a desired solution from a present situation by taking some path, which is blocked by known or unknown hurdles. Problem solving also includes decision making, which is the process of selecting the best suitable alternative out of multiple alternatives to reach the desired goal.
• Perception − It is the process of acquiring, interpreting, selecting, and organizing sensory information. Perception presumes sensing. In humans, perception is aided by sensory organs. In the domain of AI, the perception mechanism puts the data acquired by the sensors together in a meaningful manner.
• Linguistic Intelligence − It is one's ability to use, comprehend, speak, and write the verbal and written language. It is important in interpersonal communication.

Difference Between Human and Machine Intelligence

While both machine and human intelligence can learn from experiences, solve complex problems, make decisions, process and interpret the information. There are certain differences between machine and human intelligence which are tabulated below −

Aspect	Machine Intelligence	Human Intelligence
Nature	Machine intelligence seeks to build machines that can mimic human behavior and carry out human-like tasks.	Human intelligence seeks to adapt to new situations by combining a variety of cognitive processes.
Adaptability	Limited to specific tasks.	Highly adaptable across various domains.
Functionality	AI-powered machines rely on input of data and instructions.	Humans use their brains' memory, processing power, and cognitive ability.
Pace	As compared to people, computers can handle more data at a faster rate.	In terms of speed of processing, humans cannot beat the speed of AI or machines.
Reasoning	Follows predefined algorithms and rules, additionally lacks emotions and empathy.	Capable of thinking and creativity, possesses emotions, empathy, and intuition.
Social Interaction	Limited social interaction follows protocols.	Rich social skills and interpersonal abilities.
Understanding	Lacks true understanding and operates on patterns.	Deep understanding, can grasp nuances and context.

 

In the context of artificial intelligence, it is important to know how the components of intelligent systems interact and integrate to form a agent capable of solving complex problems. Following is the list of the primary components −

Perception

Perception is the cognitive process of interpreting and organizing sensory information gathered from the environment which includes cameras, microphones, and radar. Additionally, it also includes data acquisition methods and protocols used to collect data efficiently and accurately.

Reasoning

Reasoning is achieved through inference engines that use logical rules on the knowledge base, enabling the system to gain new information and make decisions. Logic frames, including propositional and first order logic are frequently used for formal reasoning processes. There are broadly two types −

• Inductive Reasoning: It conducts specific observations to make broad general statements. It starts with a general statement and examines the possibilities to reach a specific, logical conclusion. Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. For example, "Nita is a teacher. Nita is studious. Therefore, all teachers are studious."
• Deductive Reasoning: It starts with a general statement and examines the possibilities to reach a specific, logical conclusion. If something is true of a class of things in general, it is also true for all members of that class. For example, "All women of age above 60 years are grandmothers. Shalini is 65 years old. Therefore, Shalini is a grandmother."

Learning

Learning is the process that enables systems to adapt over time by processing data. This involves acquiring new data or modifying existing knowledge, skills, or behavior. Machine Learning and Deep Learning algorithms play a significant role in analyzing patterns in datasets and learning from them. The three main ways to learn in AI are −

• Auditory Learning: It is learning by listening and hearing. For example, students listening to recorded audio lectures.
• Episodic Learning: To learn by remembering sequences of events that one has witnessed or experienced. This is linear and orderly.
• Motor Learning: It is learning by precise movement of muscles. For example, picking objects, writing, etc.
• Observational Learning: To learn by watching and imitating others. For example, a child tries to learn by mimicking her parents.
• Perceptual Learning: It is learning to recognize stimuli that one has seen before. For example, identifying and classifying objects and situations.
• Relational Learning: It involves learning to differentiate among various stimuli on the basis of relational properties, rather than absolute properties. For Example, Adding a little less salt at the time of cooking potatoes that came up salty last time, when cooked with adding say a tablespoon of salt.
• Spatial Learning: It is learning through visual stimuli such as images, colors, maps, etc. For Example, A person can create a roadmap in mind before actually following the road.
• Stimulus-Response Learning: It is learning to perform a particular behavior when a certain stimulus is present. For example, a dog raises its ear on hearing a doorbell.

Decision-Making

Decision-Making depends on algorithms that determine sequences of actions to reach specific goals. Techniques such as A* Search or Monte Carlo Tree Search are commonly used along with optimization methods like Linear Programming and Genetic Algorithms to identify the best sequence of actions from various alternatives.

Linguistic Intelligence

Linguistic Intelligence refers to the capability of the system to understand and interpret natural language effectively, which includes both written and spoken. This allows systems to understand the order and meaning of words and to apply meta-linguistic skills to reflect on the use of language.

Problem-Solving

Problem-Solving is the ability to process information and find solutions to complex or challenging situations. It involves identifying the problem, generating potential solutions, and implementing the best solution effectively. The techniques used for these processes include −

• Search Algorithms: Explore techniques for example depth-first search, breadth-first search, and A* Algorithms, which are used to identify the possible solution in order to find the optimal solution.
• Heuristics: It includes strategies or methods that guide the search process in AI algorithms by providing estimates of the most effective solution. They are often used in situations where it is difficult to find an exact solution, and provide approximate solutions.
• Optimization Techniques: Methods functioning as genetic algorithms and simulated annealing to optimize the search through the available possibilities.

Action Selection

Action Selection is the process by which an intelligent agent decides what action to perform at any given time. It is one of the significant components that directly influences the agent's effectiveness in interacting with the environment. This process involves evaluating the possible actions at a particular state and selecting the one that maximizes the agent's chances to achieve its goal.

 

Howard Gardner is a development psychologist who suggested that intelligence can be in more than one way. In order to capture the full range of abilities and talents that people possess, Gardner theorizes that people do not have just intellectual capacity, but many kinds of intelligence, which include −

Gardner first outlines this theory in his 1983 book Frames of Mind : the theory of Multiple Intelligences, where he suggested each person has multiple kinds of intelligences.

Linguistic Intelligence

People who have strong linguistic-verbal intelligence have natural affinity for words and language. They possess good understanding of semantics, sound, and rhythm of words and ability to express complex meaning through language. This intelligence can be strengthened by continuous reading, writing, storytelling, and engaging in abstract reasoning.

People with linguistic intelligence will be able to use the right words and express their views effectively in various scenarios.

You have high linguistic intelligence if you possess the following traits −

• Aware of broad vocabulary and understand when and how to use certain words.
• Have the ease to grasp other languages and dialects.
• Comfortable both in speaking and writing, while using the appropriate words.

Logical-Mathematical Intelligence

Logical-Mathematical Intelligence is the ability to calculate, quantify, and carry out complete mathematical operations. Someone with strong logical-mathematical intelligence often shows interest in reasoning, recognizing patterns, and logically analyzing problems. They tend to think conceptually about numbers, relations, and patterns.

You have high logical-mathematical intelligence if you possess the following traits −

• Good with numbers and confident in taking tasks that involve quantifying things, such as math and arithmetic questions.
• I enjoy playing puzzles, logic and strategy games.

Interpersonal Intelligence

Interpersonal intelligence is the ability to understand and interact effectively with others. These individuals are skilled at sensing emotions, motivations, desires, and intentions of those around them, this can be linked to both verbal and non-verbal communication skills.

You have high interpersonal intelligence if you are good at −

• Identifying distinctions and differences among a group of people.
• Make a large group of friends and are comfortable in making conversation with strangers.
• Identifying emotions of others, and having the capability to view situations from different perceptions.

Intrapersonal Intelligence

Intrapersonal intelligence is the capacity to understand oneself and one's thoughts and feelings, and to use it in directing one's life. It also involves appreciating and respecting the human condition, in general, treating others the way they would want to be treated.

Intrapersonal Intelligence refers to self-awareness and people's ability to understand themselves.

You are said to have high intrapersonal intelligence if you possess the following −

• You are self-motivated and put yourself first.
• You are independent, aware of and take actions based on your feelings.
• You enjoy spending time with yourself.

Musical Intelligence

Musical learners possess high sensitivity to various elements of sounds like pitch, rhythm, timbre and tone. This intelligence allows them to create, produce, and reflect on music. People who possess this intelligence often are comfortable with playing music in the background while doing other things.

Great careers for people with musical intelligence are musician, composer, singer, music teacher, and conductor.

Visual-Spatial Intelligence

Visual-Spatial Intelligence is possessed by people who are strong at visualizing things in three dimensions. It involves the following capabilities −

• Mental Imagery − This capability allows one to draw an image without external reference, from memories or previous experiences.
• Spatial Reasoning − This capability is to think about objects in 3D with limited information.
• Image Manipulation − This capability involves the imagination of a change to an object even before it is done.
• Artistic Skills − This capability allows them to create artwork.

For example, teaching a spatially intelligent student about the solar system is more effective as they manipulate it in a 3D model. This will help them conceptualize the planet's size and distance between each other.

Bodily-Kinesthetic Intelligence

Bodily-Kinesthetic learners have a good understanding of their body movement, performing actions, and physical control. People who are strong in this area tend to have excellent body-mind coordination. You have high bodily-kinesthetic intelligence if you possess −

• The ability to communicate well using body language, using gestures and actions to convey your message.
• Good sense of timing when it comes to physical tasks and activities.
• The ability to handle objects controlled with the economy of movement.
