What is Artificial Intelligence?

Artificial Intelligence (AI) is the simulation of human brain functions within a machine to help it think and behave like humans. The core challenges to achieving AI comprise programming computers and machines through code, continuous learning, and the use of datasets for certain traits.

AI is a broad field in computer science that gives machines the ability to reason, understand normal situations, and solve complex problems. Applications of AI span include image recognition, speech recognition, natural language processing, decision-making, and automated processes.

AI has evolved significantly in the present day, but creating an artificially intelligent system wasn’t as simple, and the field has experienced various ups and downs over the years.

History of AI

AI dates back to the 20th century; early research explored topics like symbolic methods and trial and error to develop formal reasoning.

During the second world war, an English mathematician and computer scientist, Alan Turing documented his ideas on creating an intelligent machine. Turing’s test theory proposed that a machine, if capable of engaging in a full conversation with no detectable variances from a human, could be deemed a thinking machine. Turing worked to crack the German military’s encryption, the ‘Enigma’ code.

Later in 1956, American computer scientist John McCarthy organised the Dartmouth Conference, where the term ‘Artificial Intelligence’ was first used.

In the 1960s, the US Department of Defence (DARPA) began training machines and computers to simulate basic human reasoning. This work opened the avenues for automation and formal reasoning, including smart search systems and decision support systems that can be designed to complement and augment human abilities.

Today, AI is a much broader term, encompassing technologies from automation to deep learning. The current evolution of AI technologies continues to provide specific benefits in various industries, including healthcare, retail, government, and manufacturing.

Components of AI

A computer exhibits a form of AI when it learns to self-develop and solve problems without human intervention. Advances in technology have greatly progressed AI in terms of hardware, software, and datasets for processing. AI systems and machine learning demand robust hardware, specific software, and extensive datasets (Big Data) to address complex problems and instructions.

Hardware Components to Train AI Models

An AI problem involves a discrete set of data that cannot be easily handled by regular servers alone. A typical server consists of CPU cores, which would take months to process millions of AI threads. AI has evolved significantly, progressing from an 8-bit math performance unit to processing millions of operations per second for training data sets. This requires substantial computing power. With the increasing AI workload, there is a parallel rise in hardware requirements to effectively process these enormous workloads.

Graphical Processing Units (GPUs)

To train AI algorithms, a specific piece of hardware is required, i.e., a graphics processing unit (GPU), which is highly efficient for AI training. The introduction of GPUs in AI operations has significantly reduced processing time. The major reason for the high efficiency of GPUs in AI processing is their suitability for parallel processing. A GPU consists of thousands of cores to process data; a server with only one GPU can easily outperform a powerful server consisting of hundreds of CPUs.

This can be done through standards-based analytics on platforms that can execute all of these processes with standard integrations across the entire platform.

Internet of Things

The Internet of Things (IoT) can include a wide range of machines, sensors, smart objects, and unique identifiers (UIDs), provided they are connected to the Internet and have the ability to send and receive data without human intervention. IoT generates a large amount of data from linked devices, which are fed into the AI system to analyse and automate processes using AI models, enabling efficient utilisation of AI.

Software Components to Train AI Models

The goal of an AI system is to learn from data and provide reasons based on input while explaining outputs. AI achieves this with the help of software and decision support for tasks.

Algorithms

Algorithms are developed to process huge amounts of data at multiple stages. This involves identifying and predicting events, understanding processes, and optimising scenarios. Common algorithms used in AI include linear regression, decision trees, logistic regression, and random forest.

Application Programming Interfaces (APIs)

APIs are code snippets that allow two software programs to communicate, facilitating the addition of AI functionality to existing products or software packages.

AI Languages

AI development is not confined to a specific language; developers can use various languages such as Python, C++, Java, LISP, and Prolog. There is no hard and fast rule regarding the best programing language for developing artificial intelligence applications.

Database for Training and Running AI Models

AI works by making it possible for machines to learn from experiences and adjust to the responses based on the models and algorithms. AI works at its best when there is vast data – we refer to it as big data. Feeding big data into AI systems presents a lot of cases for AI to make it learn from data, patterns or features to develop intelligent algorithms.

This is no coincidence that indirect end-users are also contributing to the training of AI models. A popular example is the increase in the adoption of social media networks for maintaining and building relations. With enormous data, many of social media sites have setup AI research departments to impart better services to users with image recognition, speech recognition, automated bots, and language translation. This is happening with the processing of data and training AI systems to learn and evolve from human data.

Models of AI

The subsets of AI have expanded over time, enabling machines to use statistical methods and computational neural networks to improve through experiences. AI operates by combining large amounts of data with fast, iterative processing and intelligent algorithms, allowing the software to learn automatically from patterns or features in the data.

AI is a broad field of study that includes many theories, methods and technologies, as well as the following major subfields:

Machine learning (ML) uses methods from neural networks, physics, operation research and statistics to explore and identify Insights from data without externally being programmed to search for data and derive conclusions. So, ML is the machine’s ability to learn without external programs.

Computer vision relies on pattern recognition to identify a picture or a video. Machines can process, analyse and understand images in real time and interpret their surroundings. An example of this use case is an image analysis tool which is trained to recognise images of animals, humans, and objects by feeding a large number of images to make it learn. The introduction of algorithms has significantly changed machine recognition patterns.

Natural language processing (NLP) is the capability of machines to analyse, recognise, and interpret human language to respond in the same way, including speech. Machine learning has advanced, enabling it to go through text and identify the sentiment of the writer or classify music to match the mood. NLP is another popular example of machine learning used to understand human verbal or written communication and respond using similar natural methods. The next stage of NLP is natural language interaction, allowing humans to communicate with computers using normal, everyday language to perform tasks.

Deep learning is the next step in neural networks, which increases layers and neuron diversities while churning data through to train models. The ‘deep’ here refers to the enormous layers of neural networks. The capability now exists to expose multi-layered neural networks to extensive datasets.

Neural network is highly inspired by the human brain and the interconnection of neurons. But unlike the human brain where several neurons can connect to each other, software-based neural networks have distinct layers, networks, and commands of data circulation. Neural networks work on a scheme of possibilities. Based on the available data, neural networks make predictions or decisions with a certain degree of certainty with a learning part called a ‘feedback loop’. The feedback loop provides right or wrong information to help the technology in modifying the approach for future results.

Characteristics of an AI system

Artificial Intelligence is created to simplify tasks, reduce errors, improve experiences and help humans by training machines with data based on our experiences and making them learn by introducing various scenarios. Artificial Intelligence is shaping the future and businesses are embracing AI to simplify processes and improve business functions in various fields with smart objects, trained software, chatbots, robots and through other means of human cognitive skills.

Challenges around AI

AI is developing and being adopted at a great pace, but there are some concerns among users and researchers that AI could grow immensely.

Privacy. AI programs evolve with a lot of data, and such data can raise privacy concerns if misused and falls into the hands of threat actors. Additionally, AI is now capable of recognising human language and theoretically able to understand and record conversations from personal devices, emails, and telephones. This capability can raise serious concerns if not properly secured.

Ethical concerns. AI systems are replacing humans, and various jobs are being taken over by AI. In areas such as legal, health-tech, and military, AI adoption is increasing, but it can lead to serious consequences if there are errors or failures in the system.

Security. If AI systems are programmed to pose a threat to humans, it would be difficult to stop the system from creating a threat to human safety or leading to unintended consequences.

Generative AI: The Next Chapter in AI Evolution

Generative AI (commonly called Gen AI) is AI that can create new content such as text, images, audio, and other content by recognising patterns in existing data. It has been around since the 1960s and was initially used in chatbots. The technology gained attention in 2014 with the introduction of Generative Adversarial Networks (GANs), showcasing its ability to generate authentic-looking content.

Generative AI can offer several benefits to businesses and tech users. From content generation to 3D modelling, it provides efficient solutions for automating creative tasks and enhancing productivity. Some of the common Gen AI models include:
