What is Artificial Intelligence (AI)?
Artificial Intelligence (AI) is a branch of computer science focused on creating machines and software that can perform tasks requiring human intelligence, such as understanding language, recognizing patterns, solving problems, and learning from experience.
In simpler terms, AI aims to make computers "smart" so they can perform activities typically needing human brainpower, like chatting with you, finding information, or even driving a car.
A real-life application of AI is virtual personal assistants, such as Siri and Alexa. These AI systems understand spoken commands, answer questions, set reminders, play music, and control smart home devices, using natural language processing (NLP) to make everyday tasks more convenient and help manage your schedule with ease.
Evolution of AI
Even though it may seem that Artificial Intelligence is new, its groundwork, in reality started way back in the early's 1900s.
The concept of "artificial intelligence" has its roots in ancient times, with philosophers pondering the mysteries of life and death. Long ago, inventors created devices known as "automatons," which were mechanical beings capable of moving independently without human control.The term "automaton" is derived from ancient Greek, meaning "self-acting" or "acting on one's own will."
One of the earliest known accounts of an automaton dates back to 400 BCE, describing a mechanical pigeon crafted by a friend of the philosopher Plato. Centuries later, one of the most renowned automatons was designed by Leonardo da Vinci around 1495.
The journey of AI began with the idea of creating machines that could mimic human intelligence. Early AI systems were rule-based, relying on predefined logic to solve problems.
Over time, AI evolved through various stages, incorporating more advanced techniques like machine learning, deep learning, and Natural Language Processing (NLP).
These advancements allowed AI to learn from data, recognize patterns, and make decisions with increasing accuracy.
Traditional Search
One of the earliest applications of AI was in search engines.
Traditional search algorithms like Binary Search and Linear Search retrieve information by matching keywords in a query to indexed data.
They score results based on relevance factors such as keyword frequency and location, often using methods like TF-IDF (Term Frequency-Inverse Document Frequency) and BM25 (Best Matching 25).
Web searches, like those used by PageRank (used by Google), rely on heuristics to rank results.
More advanced algorithms like A Search Algorithm* (used in pathfinding and graph traversal) focus on precise keyword matching without fully understanding the context or intent.
While effective, these methods were limited in their ability to understand the context or the intent behind a user’s query.
This led to the development of more sophisticated search techniques, paving the way for AI-driven search engines that could comprehend natural language and deliver more accurate results.
The Prompt Phase
The introduction of AI models like GPT (Generative Pre-trained Transformer) marked a significant shift in how we interact with AI.
These models were trained on vast amounts of data and could generate human-like text based on a given prompt.
This capability revolutionized content creation, chatbots, and virtual assistants, making AI more accessible and user-friendly.
However, the responses generated were still largely dependent on the quality and clarity of the input prompt.
Currently, all versions of ChatGPT, including GPT-3 and GPT-4, primarily operate in the "prompt phase".
They generate responses based on the input prompt using patterns learned from their training data, without accessing external sources or databases during the generation process.
Retrieval-Augmented Generation (RAG)
As AI continued to evolve, the concept of Retrieval-Augmented Generation (RAG) emerged.
RAG combines the strengths of traditional retrieval methods with the generative capabilities of models like GPT.
By retrieving relevant information from a large corpus of data and using it to inform the generated content, RAG models can produce more accurate and contextually relevant responses.
This approach enhances the quality of AI outputs, particularly in complex and information-rich domains.
The products using Retrieval-Augmented Generation (RAG) models, particularly for advanced AI applications are:
- Facebook AI's RAG Model: Combines retrieval and generative models like BART for tasks such as question answering.
- OpenAI's Code Interpreter: Retrieves and uses code snippets or documentation to assist in software development, resembling RAG.
- Google's Search-Enhanced Models: Integrates retrieval with generative techniques for more contextually relevant search results.
- Microsoft Azure Cognitive Search: Combines document retrieval with generative models for enterprise search and support solutions.
- Haystack by deepset: An open-source framework for building RAG-based search and QA systems.
Fine-Tuning AI
Fine-tuning is a crucial step in the AI evolution, where pre-trained models are further trained on specific datasets to improve their performance in particular tasks.
This process allows AI to become more specialized and effective in various applications, from sentiment analysis to medical diagnosis.
Fine-tuning has enabled AI to move from being a general-purpose tool to a more targeted and precise solution, tailored to meet the needs of different industries.
Some of the use cases of Fine-Tuning AI:
- Sentiment Analysis for Customer Feedback: A pre-trained language model like GPT-3 is fine-tuned on a dataset of customer reviews to accurately detect and categorize sentiments (positive, negative, neutral) specific to a particular industry, such as retail or hospitality.
- Medical Diagnosis with AI: A model initially trained on general medical texts is fine-tuned on specific datasets related to radiology reports. This fine-tuned model can then assist radiologists in detecting anomalies in X-rays or MRIs with greater accuracy.
- Chatbots for Customer Service: A general chatbot model is fine-tuned on a company's customer interaction data to better understand the brand's tone, product details, and common customer queries, leading to more effective and relevant responses.
- Financial Forecasting: A pre-trained economic model is fine-tuned on a financial institution's historical data to improve the accuracy of predictions related to stock prices, market trends, or risk assessments specific to that institution.
- Legal Document Analysis: A language model is fine-tuned on legal texts and contracts to assist lawyers in quickly identifying key clauses, potential risks, or inconsistencies within complex legal documents.
The Rise of Agentic AI
The evolution of AI has culminated in the development of Agentic AI, a new breed of AI that goes beyond traditional models.
