2. History of Generative AI
The term Generative AI may be a recent trend, but its history dates back at least 70 years when humans began to question whether machines could think and process like humans. Let's take a brief journey into the world of Artificial Intelligence through its formative years.
From humble beginnings in the 1950s with the advent of text analysis to the emergence of powerful language models like GPT (Generative Pre-trained Transformer), each era marks a significant step in our research to create machines that can understand and generate human language.
2.1. The 1950s: Text analysis - The Genesis of Artificial Intelligence (AI)
During the period from the 1950s to the early 1960s, the field of Artificial Intelligence (AI) was still in its infancy. Researchers were exploring the possibility of creating machines that could simulate human intelligence. One of the earliest efforts in this direction was text analysis. This era witnessed the development of primitive computer programs designed to process and analyze textual data.
The early text analysis systems primarily focused on simple tasks such as information retrieval and keyword extraction. The idea was to make computers capable of understanding and manipulating text in a manner similar to human comprehension. While these efforts marked significant progress for their time, they were limited in capability and lacked the sophistication we associate with AI today.
2.2. The 1960s: Rule-based systems and knowledge bases
In the late 1960s and throughout the 1970s, research in artificial intelligence shifted towards rule-based systems and knowledge bases. Researchers attempted to encode human expertise and knowledge into computer programs using explicit rules and logical reasoning. This approach led to the development of expert systems, capable of solving specific problems by adhering to predefined rules.
Expert systems marked a significant advancement in the field of artificial intelligence, demonstrating that computers could perform tasks that require human expertise. However, they were constrained by the need for manually crafting extensive rule sets and limited adaptability to new domains.
2.3. The 1980s: Natural Language Processing (NPL)
The 1980s and 1990s witnessed the emergence of Natural Language Processing (NLP), a crucial field in artificial intelligence aimed at enabling machines to understand and generate human language. Researchers began developing more advanced techniques for parsing and analyzing text, paving the way for applications such as machine translation, speech recognition, and sentiment analysis.
NLP systems still primarily relied on rules, utilizing grammatical and syntactic rules. These systems were capable of handling more complex language tasks than initial text analysis, but they still fell far short of human-level language understanding.
2.4. The 2000s: Machine learning revolution and Big data
This new transition marks a significant advancement in artificial intelligence research with the explosion of machine learning and the availability of vast amounts of digital data. Machine learning algorithms, especially neural networks, have proven highly effective in solving various artificial intelligence tasks, including those related to text and language.
This era gave rise to the concept of "Big Data" and the development of large-scale data analytics. With the advent of technologies like deep learning and the availability of massive datasets, artificial intelligence models became increasingly capable of understanding and generating human language.
2.5. The 2020s: GPT-3 and a significant leap in Generative AI
In the 2020s, the world witnessed the emergence of GPT-3 (Generative Pre-trained Transformer 3), a revolutionary artificial intelligence model, marking a significant milestone in the field of artificial intelligence and natural language processing. GPT-3 has been pre-trained on an extensive corpus of text data and can generate highly fluent and contextually relevant text.
The progress of GPT continues with the introduction of GPT-3.5, the model used by ChatGPT, and GPT-4, the latest version in the GPT series.
3. What are Large Language Models (LLM)?
It would be incomplete to discuss without understanding Large Language Models (LLMs).
Large Language Models are a type of language model trained using deep learning techniques on massive text datasets. These models have the ability to generate text that closely resembles human language and perform various natural language processing tasks.
Large Language Models are trained on large, unlabeled datasets with a massive number of parameters. GPT-3, for instance, is trained with 175 billion parameters.
Unlabeled datasets can be open-source, such as Wikipedia pages, or private, like internally curated training documents, depending on the needs. The entire functionality of LLMs revolves around the probability distributions of words or sequences of words combined to form a sentence or phrase.
LLMs can predict the next word that might appear in a sentence.
The prediction of the next word is based on a specific "validity" and this validity doesn't necessarily have to be determined by grammatical rules. Instead, it is determined by the factor of how creatively humans construct language. Learning to some extent to mimic how humans write language is a result of training language on large datasets (big data).
Some popular Large Language Models (LLMs) include:
GPT 3, 3.5 and 4 of Open AI
LaMDA and PaLM of Google
BLOOM of Hugging Face
LLaMA of Meta
NeMO LLM of NVidia
In this list, Meta's LLaMA is an open-source LLM that developers worldwide use to create personalized models.
LLMs and Generative AI are related concepts, but they have significant differences in their goals, capabilities and applications.
Let's delve a bit deeper to understand more about the key Generative AI models that are currently in use today.
