Retrieval-Augmented Generation (RAG) LLMs and the Need for RAG Author: Bindeshwar Singh Kushwaha Platform: PostNetwork Academy Let’s Start With a Question Suppose you ask a Large Language Model: “What is the medical history of my uncle?” Will the LLM know the answer? Answer: No. Why Can’t the LLM Answer? LLMs are trained on public Internet […]
Transfer Learning and Fine-Tuning Large Language Models In this post, we will explore the concept of Transfer Learning, its connection to fine-tuning large language models (LLMs), and step-by-step instructions to fine-tune DistilGPT-2. What is Transfer Learning? Transfer Learning is a powerful machine learning technique where a model trained on one task is reused as the

Building a Smart Indian Food Recommender Using TinyLlama, Ollama, and Python In this tutorial, we’ll build a simple yet smart food recommender system that suggests Indian dishes based on the current humidity and temperature values. The system uses a local language model TinyLlama running via Ollama, and Python’s random.randint() function to simulate real-time weather. Why
