Symbolic Generative AI Knowledge Bot Symbolic Generative AI Knowledge Bot This is a symbolic AI chatbot designed to provide knowledge about Generative AI concepts, such as LLMs, GANs, Transformers, Datasets, and Applications. This chatbot uses symbolic reasoning to infer answers from a defined knowledge base. Get GitHub code here . Learn how it works on YouTube here . Features Dynamic reasoning based on entities and relationships from the knowledge base. Fallback responses for unmatched queries. Easily extensible knowledge base (in JSON format). Type a query about GenerativeAI (e.g., "Tell me about LLMs"). No capitalization needed! Supported terms: GenerativeAI, Datasets, LLMs, Diffusion Models, GANs, Transformers, Applications, Ethics Send Clear Tip: ask using natural language, e.g., "Tell me about GANs" or "What are the limitations of GenerativeAI?" Small d...

In this post, I explain Confusion Matrix in detail. Learn Confusion Matrix Definition and Intuition, Claim Approval Example, Confusion Matrix Table Layout, Core Concepts Explained (TP, TN, FP, FN), Confusion Matrix Formulae, Derived Metrics from the Confusion Matrix (Precision, Recall, F1, Specificity), and Visualization and Code. If you want to additionally learn about the following confusion matrix topics or comment, you can do so on my original Confusion Matrix article on LinkedIn here . Thresholding, ROC and PR Curves, Imbalanced Data and the Accuracy Paradox, Multiclass and Multi-Label Confusion Matrices (Visualization and Interpretation), Cost-Sensitive Decisions: Cost Matrix, Business Tradeoffs, and Setting Operational Thresholds, Calibration, Confidence, and When to Trust Model Probabilities, Practical Tips and Troubleshooting (Data leakage, label noise, sampling effects) — confusion matrix tutorial, debugging checklist for AI Developers and AI QA Testers, Ethics, Fairness an...

In this post, I explain Introduction to RAG in LLMs (Large Language Models), RAG Concepts in LLMs, Retrieval Modules and Vector Embeddings, Indexing Strategies and Vector Databases, Document Ingestion and Preprocessing, RAG in LLM Python, RAG Frameworks (such as LangChain and LlamaIndex), Retrieve‑Then‑Generate vs Generate‑Then‑Retrieve, Prompt Engineering for RAG and Evaluation Metrics for RAG. You can test your knowledge of LLMs in Python by attempting the Quiz after every set of Questions and Answers. If you want my complete Retrieval-Augmented Generation (RAG) Framework in LLMs document that additionally includes the following important topics, you can message me on LinkedIn : Optimization and Caching, Advanced RAG Techniques (such as RAG multimodal retrieval), RAG in LLamaIndex Example with code, Best Practices and Troubleshooting RAG and RAG in LLM consolidated Quiz with multiple‑choice questions and answers to test your knowledge. Question : What does RAG stand for in...
