"Another problem that can be confusing is that LLMs seldom put out the same thing twice. [...] Traditional databases are straightforward - you ask for something specific, and you get back exactly what was stored. Search engines work similarly, finding existing information. LLMs work differently. They analyze massive amounts of text data to understand statistical patterns in language. The model processes information through multiple layers, each capturing different aspects - from simple word patterns to complex relationships between ideas." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)
"Context is crucial for how language models understand and generate code. The model processes your input by analyzing relationships between different parts of the code and documentation to determine meaning and intent. [...] The model evaluates context by calculating mathematical relationships between elements in your input. However, it may miss important domain knowledge, coding standards, or architectural patterns that experienced developers understand implicitly." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)
"Generative AI for coding and language tools is based on the LLM concept. A large language model is a type of neural network that processes and generates text in a humanlike way. It does this by being trained on a massive dataset of text, which allows it to learn human language patterns, as described previously. It lets LLMs translate, write, and answer questions with text. LLMs can contain natural language, source code, and more." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)
"This ability to zero in on important code is why modern AI coding assistants can offer meaningful suggestions for your specific needs. It’s similar to how skilled developers know which code sections affect a new implementation the most. Each transformer layer learns about various code patterns, ranging from syntax validation to understanding the relationships among functions, classes, and modules." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)
"Unlike traditional code completion, which operates on predefined rules, generative AI creates a continuous improvement cycle, which includes the following five basic steps: (1) Developer input: You provide source code, comments, or natural language requirements. (2) Context analysis: The model analyzes patterns in your existingcode and requirements. (3) Prediction: Based on training data and your specific context, the model generates probable code. (4) Developer feedback: You accept, modify, or reject suggestions. (5) Model adaptation: The system incorporates your feedback to improve future suggestions." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)
"Generative AI has a lot of problems because it needs a lot of data to work. Generative models like GPT and GANs need a lot of training data to learn patterns and make good outputs. This data dependency can cause problems like overfitting, which happens when the model does well on training data but doesn’t work well with new, unseen data. Also, the quality of the content that is generated is directly related to the diversity and representativeness of the training data. This means that biased or incomplete datasets can lead to outputs that are wrong or unfair." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)
"[...] KGs and LLMs can be the foundation for different types of reasoning, complementing each other in intelligent systems. We can use KGs for tasks that require precise, rule-based reasoning and explicit knowledge representation, and LLMs for tasks involving pattern recognition, context understanding, handling ambiguity or incomplete information, and reasoning about graph structures and their derived metrics. However, neither approach inherently possesses common-sense reasoning capabilities comparable to those of humans, and they often fail to make intuitive leaps or understand the implicit context that would be obvious to a person. These limitations underscore the importance of carefully considering the strengths and weaknesses of each approach when designing intelligent systems and potentially developing a powerful hybrid IAS." (Alessandro Negro et al, "Knowledge Graphs and LLMs in Action", 2026)
"Machine learning was a big change because it let systems learn patterns from data instead of having to follow hardcoded rules. AI could generalize better and change to new inputs thanks to techniques like decision trees and support vector machines. These models still needed a lot of work to get the features right, though, and they couldn’t handle high-dimensional data like images or text very well. The breakthrough happened when deep learning, a type of machine learning that uses neural networks with multiple layers to automatically learn hierarchical representations of data, became popular. Convolutional neural networks (CNNs) for processing images and recurrent neural networks (RNNs) for sequential data changed what AI could do. Architectures like GANs and transformers took things even further by making it possible to do things like make images, understand natural language, and more." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)
"RAG models offer several advantages over standard generative models, addressing many of their limitations. Traditional generative models, like GPT, rely solely on patterns learned during training, which can lead to issues such as factual inaccuracies, model hallucinations, and lack of contextual relevance. These models generate content based on pre-existing knowledge, often without the ability to verify or update the information, making them less reliable for tasks requiring high accuracy. In contrast, RAG models integrate retrieval mechanisms that allow them to access external knowledge sources in real time. This ensures that the generated content is grounded in verified data, significantly improving factual consistency and relevance. For example, while a standard generative model might produce a plausible but incorrect answer to a factual question, a RAG model can retrieve and incorporate accurate information from a trusted source, reducing errors." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)
"Retrieval mechanisms are essential for addressing some of the key limitations of traditional generative AI models, such as factual inaccuracies, lack of context awareness, and model hallucinations. While generative models excel at creating coherent and fluent content, they often struggle to produce outputs that are factually correct or contextually relevant. This is because these models rely solely on patterns learned during training, without access to real-time or external information. For example, a generative model might generate a plausible-sounding but incorrect answer to a factual question, as it cannot verify the accuracy of its response." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)
"The foundational form of RAG, often called naive RAG, follows a straightforward pattern. A pipeline retrieves supporting context from external sources such as enterprise documents, knowledge bases, or structured datasets and appends that information to the model’s prompt before inference. In the most common implementation, each document is converted into an embedding, a numerical representation of its semantic meaning, using either the same foundation model or a specialized embedding model. When a user submits a query, the system performs a vector similarity search to find documents whose embeddings most closely match the query’s vector representation, and the retrieved content is concatenated with the user query before being passed to the language model." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)
"Traditional paradigms build systems for specific purposes with structured, homogeneous databases. This approach works for tailored needs but is impractical for complex domains that need to adapt to user characteristics and integrate heterogeneous data. KGs capture connections, enabling relationship discovery through graph pattern matching and traversal. Both the Resource Description Framework (RDF) and Labeled Property Graphs (LPGs) provide machine-readable formats that humans can interpret. KGs emphasize rich, meaningful data representations usable by both humans and machines, enabling a paradigm shift where intelligent behavior is encoded in a unique source of truth."
