Understanding AI Terminology: A Beginner's Guide
AI has been around since the 1950s; however, many people were not aware of this transformative technology until the 2020s. There have been several advancements made, but it was not popular until the launch of ChatGPT, which took the internet by storm by reaching millions of users in just 5 days, a feat that took Instagram, Netflix, and Spotify months and years.

Now, several AI-powered tools are available in the market for content markets, designers, and business owners, taking humans’ productivity and creativity to the next level.

With the growing popularity, netizens are getting confused.

***Generative AI Terms to Know in 2024* **
Generative AI terms are popping up everywhere with the emergence of popular tools such as ChatGPT, Bard, etc. This landscape could be exciting and confusing for beginners, as several terms are interchangeably used. Though the list is comprehensive with many hundreds of words, we will be jotting down some of the most popular Gen AI terms here that every professional should know.

1. Artificial intelligence
Artificial intelligence (AI) is a broad field focused on creating machines and programs to perform tasks that typically require human intelligence, although not as often depicted in fiction.An AI-powered machine and program can perform tasks such as learning, reasoning, problem-solving, understanding natural language, and perception.

AI was conceptualized in the 1940s and 1950s, with the aim of enabling machines to think and operate autonomously. Over the decades, AI has developed into various subsets, each focusing on different aspects of intelligent behavior.

One subset is generative AI, which includes technologies that can create content autonomously. Generative AI includes models capable of generating text, images, music, and other forms of content by understanding and mimicking patterns found in the data they are trained on.

2. Neural networks
Did you know the human brain is the inspiration behind neural network architecture? In our brains, there are cells called neurons. These neurons form a highly complex and interconnected network to send electrical signals that help humans process information. The neural network is made up of artificial neurons (also called nodes) that send signals to one another. You can consider them a building block that contains information about the patterns and relationships in the data on which they were trained.

There are different types of artificial neural networks exist today:

• Feedforward neural networks (FF), one of the oldest forms of neural networks.
• Recurrent neural networks (RNN), used for speech recognition, translation, and to caption images.
• Long/short-term memory (LSTM)
• Convolutional neural networks (CNN)
• Generative adversarial networks (GAN)

3. GPT
GPT stands for generative pre-trained transformer. It is developed by OpenAI, the company behind the popular ChatGPT tool. ChatGPT contains GPT, so now you might be wondering exactly what a generative pre-trained transformer(GPT) is.

Apart from ChatGPT, millions of other generative AI models (or applications), surfacing across the internet, are built upon GPT. This simply means behind the scene GPT is being operating with some custom modification to fine tune it. This is why major chatbots write in similar tones because they in the end have same brain or program (or GPT model). Model can be considered the brain of your program.

OpenAI has rolled different version of GPT models which include GPT 3.5 , GPT 4, GPT 4.0, some are paid with advanced capabilities while 3.5 is available for free to use for public.

4. NLP
NLP stands for Natural Language Processing. It refers to the processing of natural languages like the ones we speak and write, as opposed to machine languages. Nowadays, machines are capable of understanding and processing our natural language. You can communicate with them using your everyday language, and they can grasp your intent.

NLP is a subset of artificial intelligence that enables interactions between machines and humans. When a system, machine, or program has NLP ability, you can interact with it using your own language. For example, AI Chatbots can understand sentiments like humans and respond accordingly. Have you ever wondered how they do it? It's the NLP technology behind them that powers them to understand our sentiments.

5. GAN
GAN stands for Generative Adversarial Network, a type of neural network model. In this model, two neural networks compete against each other to generate authentic results. One network generates new data, while the other tries to distinguish if it's real or fake. They continue improving until the second network can't distinguish fake from real anymore. GAN includes a generator and a discriminator, two neural networks that work in tandem to generate content.

**6. Discriminator
**The discriminator is a type of neural network that competes against a generator in a GAN (Generative Adversarial Network) to help the generator produce data that is indistinguishable from real data. Artificial intelligence is indeed trained through a process similar to how humans learn. When someone criticizes something you create, it allows for improvement, and this iterative pattern is applied in machine learning as well. Machines enhance their performance and results through feedback mechanisms.

Similar adversarial concepts can be found in other models besides GANs, although they may not be referred to as GANs. This method, where two neural networks compete against each other to produce more authentic results, is common in machine learning. The discriminator is a key component inside GANs, responsible for distinguishing real data from fake data.

**7. LLM
**LLM stands for large language models. In AI, a large language model refers to a computer program that is trained on massive amounts of text data from the Internet, books, articles, and more – thousands or millions of gigabytes' worth of text. Based on what it has learned, it can understand written language, write essays, answer questions, and even hold conversations.

Here are some examples of large language models (LLMs):

• GPT (Generative Pre-trained Transformer) series by OpenAI
• BERT (Bidirectional Encoder Representations from Transformers) by Google
• T5 (Text-To-Text Transfer Transformer) by Google
• XLNet by Google Brain
• CTRL (Conditional Transformer Language Model) by Salesforce
• Megatron by Nvidia
• Turing-NLG by Microsoft

8. Deep Learning
In the field of AI, different methods are used to train AI models. One prominent approach involves neural networks with many layers (hence "deep") to model complex patterns in data. Deep learning has revolutionized many fields within artificial intelligence. However, it's important to note that deep learning is just one approach among several in machine learning.

*9. Model *
AI models, or artificial intelligence models, are computer programs that find patterns in large sets of data. They can take in information, analyze it, and then make decisions or perform actions based on what they've learned. As we have learned ChatGPT, Google’s Gemini are AI models, specifically large models.

10. Supervised learning
Several machine learning models utilize supervised learning. It is a subset of machine learning that uses labeled datasets to train algorithms to recognize patterns. Data labelling in machine learning is the process of identifying and label raw data.

For example; a label may indicate if the object is a bird or car. Labelers may assign tags by simply saying yes/no. In supervised learning, ML model uses human-provided labels to learn the underlying patterns in a process called "model training.

*11. Unsupervised learning *
In unsupervised learning, machines learn without human supervision. In this learning, the machine is provided with raw data to discern patterns and insights without any explicit guidance or instruction.

*12. Multi-model AI *
Multi-model AI programs are gaining traction in the 2024 as they come up with advanced capabilities to process a variety of inputs, including text, images, and audio, video and convert these inputs into differentn formats. Google’s GEMINI is one of the popular multi-model AI program that can read and extract data from images.

13. Reinforcement learning
Reinforcement learning (RL) is a type of machine learning where software learns to make decisions through trial and error. It mimics how humans learn by trying different actions and remembering what works. Good actions are rewarded, and bad ones are ignored.

RL algorithms use rewards and punishments to learn the best way to achieve their goals. They can even handle situations where they need to make short-term sacrifices for long-term benefits. This makes RL a powerful tool for training AI to perform well in new and unpredictable situations.

14. Prompt
A prompt in AI is a command written in natural human language that describes the task the AI model should perform. A prompt can be text, images, or any other data. The quality and specificity of the prompt can significantly influence the quality and relevance of the generated output.

15. Token
In AI, a token is a basic unit of data that algorithms process, especially in natural language processing (NLP) and machine learning. Tokens are parts of a larger dataset and can be words, characters, or phrases.

For instance, when handling text, a sentence is split into tokens, where each word or punctuation mark is a separate token. This step, called tokenization, is essential for preparing data for AI models.

Tokens are not limited to text. They can represent different data types and are vital for AI to understand and learn from these types. In computer vision, a token might be a segment of an image, like a group of pixels or a single pixel. In audio processing, a token could be a short snippet of sound. This versatility makes tokens crucial for AI to interpret and learn from various forms of data.

16. Hallucinations
In AI, hallucinations refer to instances where a model generates output that seems plausible but is actually incorrect or nonsensical. This is common in natural language processing (NLP) when an AI system produces text that looks coherent but is factually wrong or misleading.

For example, a chatbot might confidently provide a made-up answer to a question, or a text generation model might invent details that were not present in the original data. Hallucinations occur because the model predicts based on patterns it learned during training, rather than verifying the accuracy of the information.

17. Generative models
Generative models are a type of AI that creates new data similar to the data they were trained on. They learn the underlying patterns and structures of the training data and use this knowledge to produce new, similar instances. For example, a generative model trained on text data can produce new sentences or paragraphs that mimic the style and content of the original text.

Similarly, in image processing, a generative model can create new images that resemble the training images. These models are widely used in applications like text generation and image synthesis.

Conclusion
Artificial intelligence, or AI, is growing fast, but it's still new. However, looking at things now, it's clear that it will soon be a big part of our lives.
