Introduction

I. INTRODUCTION

Artificial Intelligence (A.I.) can be described as the capability of artificial intelligence to display human-like capabilities similar to solving challenging real-world problems by using its own intelligence. Artificial intelligence (AI) is the emulation of human intellect in computer programmes that are designed to teach robots how to use human-based abilities like literacy, logic, and problem-solving. This term may be connected to any machines that show relatedness to a human intellect similar to literacy, decision-making, logic, and perception. AI trials to make machines that can emulate human gesticulation and perform human-like tasks with artificial intelligence, you can produce a machine with algorithms that can work with its own intelligence rather than being preprogramed to carry out a particular task.

 II. TYPES OF AI

A. AI type-1: Based on Capabilities

1. Narrow AI: Systems of artificial intelligence that are created and trained to carry out particular functions within a well-defined domain are referred to as narrow AI. Because these AI systems lack general intelligence and are instead taught to carry out a specific task, they are often referred to as "weak AI" or "specialised AI." Apple's Siri is one of the most widely used examples of narrow AI since it lacks general intelligence and reasoning capabilities and is instead intended to carry out a specific purpose. As a result, it frequently struggles with activities that fall outside of its capabilities. IBM's Watson is technically a complex incarnation of narrow AI, as it uses an expert system approach combined with machine learning and natural language processing. Examples of narrow AI systems include speech recognition software, self-driving automobiles, image recognition systems, disease mapping and prediction tools, chatbots and conversational assistants, etc.
2. General AI: General AI, also known as Artificial General Intelligence or AGI, is a sort of intelligence that is capable of performing any intellectual task with the same efficiency as a human. The goal of general AI is to develop a machine that can comprehend any task and carry it out flawlessly. Worldwide efforts are currently being made to develop machines with the ability to understand the world and interact with it in complex and meaningful ways. Even though the development of general AI is still purely a theoretical concept, it represents a potentially game-changing technological advancement that might have a significant impact on many facets of human activity, including business, education, and even medicine.
3. Super AI: Super AI, often referred to as Artificial Super Intelligence (ASI), is a form of advanced artificial intelligence in which machines are able to outperform people at any task that requires cognitive ability. Super AI is capable of performing creative tasks that are beyond human capabilities, similar to working on some of the world's most sensitive problems, such as climate change, solving complaints, or discovering new inventions that are beyond human imagination. The decision-making and problem-solving capabilities of machines with superintelligence are anticipated to be more precise than humans because the human brain’s thinking capability is limited to a set of many billion neurons.

B. AI type-2 Based on Functionality

1. Reactive Machines: Reactive machines are a type of artificial intelligence (AI) system that responds to specific stimuli based on preprogrammed rules without keeping track of memories or past experiences to inform their decision-making processes. IBM's Deep Blue system, which ultimately competed and won a chess match against reigning world champion Garry Kasparov, is a notable example of reactive AI. Spam filters and the Netflix recommendation engine are other examples of reactive machines.
2. Limited Memory: Limited memory AI is the next most sophisticated AI that refers to use of artificial intelligence techniques to solve problems or perform tasks when there are constraints on the amount of memory available to the system and can store past experiences or some data for a short period of time. With limited memory AI, the AI environment is built so that models are automatically trained and as a result Self-driving automobile are one of the best examples of Limited Memory systems as they can store data like recent speed of nearby cars, GPS position, the distance of other cars, speed limit. The reaction time of autonomous vehicles is improved significantly with the help of limited memory AI so that Self-driving automobiles would drive like a person.
3. Theory of Mind: Theory of Mind refers to the development of artificial intelligence systems that can understand intentions, emotions, beliefs, adjust behaviour based on those emotions just as humans can in social interactions. Example, robot Kismet (introduced in 2000) recognized emotions and could replicate them through its facial features such as eyes, eyebrows, lips and ears and humanoid robot Sophia (introduced in 2016) was also able to “see” emotions and respond appropriately.
4. Self-Awareness: Self-awareness in AI refers to the capability of an artificial intelligence system to have its own knowledge, sentiments, and self-awareness. In practical terms, self-aware AI systems would be suitable to fete and dissect their own study processes, form informed opinions grounded on their own gests, and indeed learn from and acclimatise to their miscalculations. This position of complexity would enable them to operate further autonomously, potentially achieving a position of sentience. At the moment, this AI hasn’t been developed successfully yet because we don’t have the tools or algorithms that will support it.

III. WORKING OF AI

1. Cognitive Computing: Cognitive computing aims to imitate and ameliorate communication between humans and machines. By comprehending spoken language and the intent behind visual cues, cognitive computing aims to simulate the human learning process in a machine. Together, cognitive computing and artificial intelligence strive to endow machines with human-like conduct and information processing capacities. Cognitive computing has numerous implicit operations in various sectors, including healthcare, finance, manufacturing, and client service, among others.

2. Computer Vision: The branch of computer science and engineering known as computer vision focuses on giving machines the ability to understand and give computers the ability to detect and analyse items in photos and videos in the same manner that people do. It involves the creation of methods and algorithms that can take data from digital photos or videos and use it to guide decisions or drive activities. Typically, the computer vision process contains several steps, such as the collection and preprocessing of picture data, the extraction of pertinent features or patterns from the data, and the use of machine learning algorithms to categorise or interpret the data. In order to diagnose patients more quickly, x-ray images of patients are analysed using computer vision.

2. Machine Learning: An artificial intelligence branch known as machine learning (ML) enables computers to autonomously learn from their experiences and develop without the need for explicit programming. The goal of machine learning is to create algorithms that can analyse data to find correlations and patterns that will allow users to predict outcomes for upcoming or unforeseen data. Supervised, Unsupervised, and Reinforcement learning are the three primary categories of machine learning techniques. Machine learning is currently employed in many applications, including Facebook friend suggestions, face recognition, cyberfraud detection, and natural language processing. Leading companies like Netflix and Amazon have developed machine learning models that analyse massive amounts of data to identify consumer preferences and make product recommendations in line with those preferences.

4. Neural Networks: The artificial intelligence system known as neural networks, often referred to as Artificial Neural Networks (ANN) or Simulated Neural Networks (SNN), teaches computers to process data in a way that is modelled after the way the human brain does. An input layer, one or more hidden layers, and an output layer are all components of their network of interconnected neuronal layers. One of neural networks' advantages is their capacity to recognise intricate patterns and relationships in data, even when those connections aren't necessarily bizarre. It develops an adaptive system that computers utilise to learn from errors and simulate complicated, nonlinear links between inputs and outcomes. One of the most well-known neural networks is ChatGPT.

5. Deep Learning: Artificial neural networks are a key component of the machine learning subfield known as deep learning because they closely resemble the human brain. Deep learning is thus also a dangerous imitation of the brain. Feedforward Neural Networks (FNN), Convolutional Neural Networks (CNN), and Recurrent Neural Networks are the three most popular architectures used in deep learning (RNN). Large volumes of labelled data are often fed into a deep learning model during training, and the neural network weights are adjusted using a technique called backpropagation to reduce mistakes in the training data. The model can be used to generate predictions on fresh, unpublished data after it has been trained. Deep learning has produced ground-breaking outcomes in a range of applications, including picture and word recognition, natural language processing, and more. For forecasting, anomaly detection, and process optimisation, it has also been employed in sectors like healthcare, banking, and manufacturing.

1. Natural Language Processing: Natural language processing (NLP) enables computers to read, comprehend, and interpret human languages. Speech recognition, word processing, automatic summarization, content segmentation, natural language understanding, and natural language synthesis are just a few of the jobs that NLP can handle. NLP is frequently used in chatbots, machine translation, sentiment analysis, and spam detection. NLP algorithms often analyse and interpret natural language data using statistical and machine learning methods in order to complete these objectives. The special difficulties of working with human language, such as ambiguity, context dependence, and imagery, are also addressed by NLP. For instance, an NLP system must be able to recognise several word meanings inside a sentence or comprehend the meaning of a metaphor or language.

IV. AGENTS IN AI

An agent is a computer entity in artificial intelligence that is created to observe its surroundings, make decisions using sensors, and perform actions to accomplish a specified objective or set of goals using actuators. The agent operates autonomously to achieve a specific task. Depending on the objective and the level of intelligence necessary to complete it, many agents are utilised in AI.

1. Simple Reflex Agent: The most basic kind of agent is a simple reflex agent. It merely uses the current perception as input to choose the appropriate action and operates according to a set of pre-established rules.
2. Model-Based Agent: In order to make decisions, a model-based agent keeps an internal model of its environment. To make better selections, it might consider prior perceptions and actions.
3. Goal-Based Agent: A goal-based agent is created to accomplish particular objectives. It chooses activities based on the objectives it must accomplish and the state of the environment at the time.
4. Utility-Based Agent: Based on the expected utility or value of each activity, a utility-based agent chooses which actions to take. It takes into account the potential results of every action and chooses the one with the greatest expected usefulness.
5. Learning Agent: A "learning agent" is an artificial intelligence agent that has the capacity to learn from its past experiences. Starting with fundamental knowledge, it may act and adapt independently through learning.

The four main conceptual parts of a learning agent are:

a. Learning element: This element of the agent is in charge of experience-based learning. It uses the benefits or penalties it receives from the environment as feedback to enhance its performance. The learning component can employ supervised, unsupervised, or reinforcement learning, among other forms of learning algorithms, to learn from experience.

b. Critic:  The critic component of the agent rates how well the learning aspect performed and offers suggestions for improvement. To provide feedback to the learning element, it examines the actions taken by the agent and the feedback it has received from the environment.

c. Performance element: Choosing actions depending on the environment's current state is the responsibility of this component of the agent. Based on the knowledge that the learning element has gathered, the performance element chooses the optimum course of action.

d. Problem Generator: The agent's problem generator component comes up with new tasks for the agent to learn. Based on the agent's current knowledge and skills, it chooses activities that are difficult but doable.

In AI, agents are essentially computational beings with the ability to sense their surroundings and take appropriate action to fulfil predetermined objectives. Depending on the objective and the level of intelligence needed to complete it, various types of agents are utilised in AI.

V. APPLICATIONS OF AI

The average technology user interacts with artificial intelligence technologies on a regular basis in a variety of ways, although most people are unaware of the devices that use AI. Below are some instances of artificial intelligence technology that are commonplace in modern society:

1. Robotics: AI is employed in the creation of autonomous robots and their design. This includes social robots used in healthcare and education as well as industrial robots used in production and logistics.
2. Computer Vision: A branch of artificial intelligence called computer vision enables machines to comprehend and interpret visual data. It is employed in tasks including picture classification, object detection, and facial recognition.
3. Predictive Analytics: Machine learning algorithms are used in predictive analytics to examine data and forecast future events. Applications like fraud detection, risk management, and customer analytics all make use of it.
4. Autonomous Vehicles: AI is employed in the development of autonomous vehicles, including self-driving cars. It consists of techniques for computer vision and machine learning that enable moving objects to observe their surroundings and make decisions in response to that observation.
5. Natural Language Processing: Natural language processing (NLP), which enables communication between machines and people, is another AI idea that can aid engineers. Imagine an engineer conversing with a tool to obtain advice from the latter regarding the real-time reinforcement of an assembly line process. Even if it's still only a notion, this might be something to look into. Virtual assistants, chatbots, and voice-activated systems like Siri and Alexa all make use of it.
6. Big Data: Data is increasingly widely used across many businesses. Organisations that want to outperform their rivals are investing heavily in information, which has become a coveted commodity. But without AI technologies that let users gather, analyse, and provide context, no data would be relevant. AI can offer businesses algorithms that are capable of identifying errors and developing improvements to their processes through machine learning (ML).

Large-scale urban initiatives can be facilitated by engineers using big data and AI. They can use technology to locate people and decide what public infrastructure initiatives to implement to address a range of problems.

VI. ADVANTAGES OF AI

1. Reduction in Human Error: The ability of artificial intelligence to eliminate human mistake is one of its greatest accomplishments. If properly programmed, a computer can't make mistakes like people can, whereas humans occasionally do. Artificial intelligence therefore makes use of a collection of algorithms to acquire data that has already been stored, lowering the likelihood of error and raising the accuracy and precision of any task. As a result, artificial intelligence (AI) aids in the error-free solution of challenging computations needed to tackle complicated problems.
2. 24/7 Availability: A machine doesn't need breaks or refreshers like people do. In contrast to a human, a computer machine can operate continuously for 24 hours without a pause and doesn't even feel bored, unlike a regular human who can only work for 8 to 9 hours before taking breaks and rest periods. The best illustration of continuous, round-the-clock customer assistance provided by numerous websites is provided by chatbots and help desks, which automatically respond to clients' questions using artificial intelligence.
3. Quick decision: A machine, as opposed to a human, assists in making judgements and carrying out activities more quickly. Humans consider a variety of aspects while making decisions, whereas machines focus on the preprogrammed tasks and produce results more quickly. The best illustration of a quicker judgement can be found in a third-level online chess game. A computer machine is impossible to defeat because, according to the algorithms at work, it always chooses the best action in the shortest amount of time.
4. AI in perilous circumstances: Machines always prioritise human safety as the most important factor. In dangerous conditions when human survival becomes challenging, scientists use AI-enabled devices whenever we need to research space or explore the deepest region of the ocean. Everything that humans can't reach, AI can.

VII. DISADVANTAGES OF AI

1. Risk of Unemployment: Will AI replace humans? is a topic that has been plaguing our intuitive brain in light of the field's tremendous advancement. In all honesty, I'm not sure if artificial intelligence will increase unemployment or not. Yet, most repetitive tasks that are mainly binary in nature and have little room for subjectivity will likely be replaced by AIs.
2. Rise in human laziness: Since early childhood, we have been taught that neither computers nor other machines have feelings. People function as a team, and team management is essential for achieving goals. Yet, there is no denying that robots are superior to humans when functioning effectively, but it is also true that human connections, which form the basis of teams, cannot be replaced by computers.
3. Inaccurate Data Analysis: The only way AI algorithms can learn is from the data we provide them with. Your results, however, can be inaccurate or biased if the programme is provided with flawed or unreliable data. The quality of the data you give AI determines its intelligence and efficacy. One of the main barriers to the application of AI is data consistency. Companies that want to use AI at scale often struggle since it is typically inconsistent, fragmented, and of poor quality. We should have a clear strategy in place from the start for collecting the data that AI will require in order to prevent this.
4. Bias in Algorithmic: Algorithms are a set of instructions that a computer uses to carry out specific tasks. There is a chance that a human programmer wrote these rules. Yet if algorithms are incorrect or biased, we cannot rely on them since then we would only get bad results. Biases mainly arise from the algorithm's partial design by programmers who prioritised a certain desired or self-serving criterion. Algorithmic prejudice is a common problem on large platforms employing algorithms, such as social media sites and search engines. For instance, a Facebook algorithm created a hate speech deletion algorithm in 2017. Yet, it was eventually shown that the algorithm allowed hate speech against black children but not against white men.

VIII. THE Al CONTROL PROBLEM EXPLANATION

The notion that Al will someday become more adept at making judgements than people is known as the Al control problem. According to this theory, if humans don't set up things properly in advance, we won't have the opportunity to fix things later, meaning Al will have complete power. At the very least, it will take years for current research in artificial intelligence (AI) and machine learning (ML) to surpass human capabilities. Al will likely surpass humans in terms of intelligence and productivity, based on the rate of technological advancement.

This is not to argue that ML and AL models are without limitations. After all, they are constrained by the constraints imposed by the computational complexity, the physical laws, and the processing capability of the hardware supporting these systems. It is safe to presume that these boundaries are well above what is possible for humans. This means that, if correctly constructed with controls in place to check any possibly rogue behaviour, superintelligent Al systems could represent a serious threat. Such systems must be created from the ground up in order to respect human values and restrain their power. The control problem's assertion that everything must be configured properly refers to this.

Without the necessary safeguards, if an AI system were to surpass human intellect, the outcome could be disastrous. As numerous jobs are completed more effectively or efficiently, such systems could take over the management of physical resources. All systems are built to operate as efficiently as possible; losing control could have negative effects.

IX. FUTURE OF AI

Artificial intelligence, whether we realise it or not, is a part of our daily lives and has already had a significant cultural impact. The use of AI in daily life has become widespread, from chatbots to Alexa and Siri. In this area of technology, evolution and advancement are occurring quickly. It took many years of gruelling work and the contributions of many individuals to get AI to this point. Because it is such a cutting-edge technology, AI has been the subject of several discussions on its implications for the human race. Although it could be dangerous, this is also a great opportunity. AI will be applied in a variety of ways to enhance our daily lives.

Conclusion

Like some individuals, AI systems frequently place too much faith in their own prowess. Many AI systems, like haughty people, also fail to acknowledge their mistakes. An AI system may occasionally find it more difficult to spot its mistakes than to provide the appropriate response. The enormous volumes of data that existing AI systems require to accomplish even the most basic tasks greatly limit their potential applications. Several experts believe that improvements in technology and algorithms are necessary to overcome AI\'s current limits. Even some claim that quantum computers are essential. Recognising AI\'s limitations is the best thing we can do for it as it progresses. Even though we are a long way from creating artificial intelligence that can compete with human intelligence, corporations are finding innovative ways to get around these restrictions. In the past, artificial intelligence (AI) has operated as a \"black box,\" where the user inputs the questions and the algorithm generates the answers. It developed out of the need to programme complex tasks because no programmer could possibly write every possible logical outcome. So, we let the intelligence explore at its own pace. AI has not yet had a significant impact on everyday life for the average person and is now only used in a few sectors, including the military, space, industry, healthcare, neutral networks, and geology. It is possible to anticipate that by the end of 2035, thanks to extensive research and development in the field of artificial intelligence, we will be able to move away from the machinery of today that must come with cumbersome manuals regarding machine languages and create machinery that can fully understand humans. Robots will soon work as doctors in hospitals, professors in classrooms, and bus drivers. That will be the transhumanist period, in which humans and machines will combine to create cyborgs or cybernetic organisms that are more capable and potent than either, according to Bostrom.
