AI Bites: The Academic Series

EP 41 | CS224N: Word Vectors

How do you teach a computer the actual meaning of a word? In this episode, we dive into the fundamental building block of modern NLP: Word Vectors. We break down how algorithms map words into a dimensional space, allowing machines to mathematically understand context, similarity, and semantic relationships. Key Topics: * Moving Past One-Hot Encodings: Why simply assigning a random 1 or 0 to a word fails to capture its actual meaning. * Word2Vec (2013): The breakthrough framework that learns word representations by predicting surrounding context words (Skip-gram and CBOW). * Semantic Math: How vector geometry perfectly captures complex relationships (e.g., the famous "King - Man + Woman = Queen" example).

EP 40 | CS224N: History of NLP

Welcome to a brand new series! We are diving into Stanford's CS224N. To understand where AI is today, we first need to understand how we got here. In this episode, we trace the evolution of Natural Language Processing from early rigid experiments to the deep learning revolution that powers modern language models. Key Topics: * The Early Days: The struggles of symbolic, rule-based systems and manual dictionaries like WordNet. * The Statistical Era: How probabilistic models and machine learning began to change the landscape in the 1990s. * The Deep Learning Shift: Why neural networks ultimately became the dominant, scalable force in language processing.

EP 39 | CME295 in 15 Minutes (The Full Recap)

Short on time? We’ve distilled the entire Stanford CME295 course into a single, high-energy video recap. This "Cram Session" takes you on a complete journey from the absolute basics of natural language processing to the cutting edge of Large Language Models. Watch or listen for the "Best Of" our course deep dives: * The Foundation: Moving past RNNs into the Self-Attention revolution and the core Transformer architecture. * The Training Pipeline: The massive undertaking of Pre-training, Supervised Fine-Tuning (SFT), and Preference Tuning to build a safe assistant. * Reasoning & Agents: How models use Chain of Thought to solve multi-step problems , and how RAG and Tool Calling turn them into autonomous agents. * The Future: A look at what's next, including Vision Transformers (ViT), Diffusion LLMs, and highly capable Small Language Models (SLMs).

EP 38 | CME295: Recap & Future Trends

We have reached the end of Stanford's CME295! In this course finale, we zoom out to summarize the entire journey—from the underlying Transformer architecture to the massive engineering feat of training and tuning LLMs. Then, we look ahead to the absolute cutting edge of AI research. Key Topics: * The Course Recap: A quick refresher on Architecture, Pre-training, Fine-tuning, and Agentic capabilities. * Multimodality: The shift from text-only models to AI that can natively see, hear, and generate audio and video simultaneously. * Efficiency and SLMs: Why the future isn't just about building bigger models, but creating highly capable Small Language Models (SLMs) that can run locally on your devices.

EP 37 | CME295: LLM Evaluations

If an AI can write a poem, code a website, and pass the bar exam, how do we actually measure its performance? This episode tackles the notoriously difficult science of LLM Evaluation. We look at why standard testing benchmarks are breaking down and how researchers are trying to keep up. Key Topics: * The Benchmark Problem: Why traditional multiple-choice tests are saturating and failing to capture true model intelligence. * LLM-as-a-Judge: The growing trend of using powerful models (like GPT-4) to grade and evaluate the outputs of other models. * Data Contamination: The massive challenge of testing a model when its training data essentially includes the entire internet—did it reason through the test, or just memorize the answer key?
