E12. An Overview of Model Training

E14. An Overview of MLOps

Episode 14: An Overview of MLOps In our season finale, we answer the most practical question of all: What happens after the model is trained? We explore MLOps—the critical "assembly line" practices that take a model from a laptop experiment to a production-ready system. In this episode, we cover: * The Origin: How the concept of "Technical Debt" led to merging ML with DevOps. * The Pipeline: A tour of the 5 key components, including Feature Stores, Deployment, and Monitoring. * The Enemy: Understanding Data Drift and Model Drift (why models get worse over time). * LLMOps: The new challenges of managing Large Language Models and "Hallucinations." * Maturity Levels: The journey from Level 0 (Manual) to Level 3 (Fully Automated). Series Conclusion: This wraps up our "Fundamentals" series. Stay tuned for our next season where we delve deeper into specific algorithms!

E13. An Overview of Machine Learning Libraries

Episode 13: An Overview of Machine Learning Libraries Developers don't build AI from scratch. In this episode, we open the toolbox to explore the essential Machine Learning Libraries and frameworks that power the industry. In this episode, we cover: * The Foundation: Why NumPy and its "tensors" are the bedrock of all ML code. * The Core Frameworks: * TensorFlow: Google's powerhouse for production and scaling. * Keras: The user-friendly interface for deep learning. * PyTorch: Meta's flexible favorite for researchers. * Scikit-learn: The standard for traditional algorithms (Regression/Clustering). * Specialized Tools: Pandas for data analysis, Matplotlib for visualization, Hugging Face for pre-trained models, and MLflow for experiment tracking. Next Episode: We wrap up the season by discussing how to manage these models in the real world with ML Ops.

E12. An Overview of Model Training

Episode 12: An Overview of Model Training We've used the word "training" in every episode. Now, we break down exactly what it means. In this episode, we explore the step-by-step workflow of how a model actually "learns" from data. In this episode, we cover: * The Core Concept: How "learning" is really just adjusting mathematical Weights and Biases to minimize a Loss Function. * Model vs. Algorithm: Why these terms aren't interchangeable (Recipe vs. Meal). * The 3 Paradigms Recap: A quick look at how Supervised, Unsupervised, and Reinforcement learning differ in their goals (Accuracy vs. Pattern Finding vs. Reward Maximization). * The 8-Step Workflow: From Data Collection and Hyper-parameter Selection to Back-propagation and Optimization. * Evaluation: Why we split data into Training, Validation, and Test sets to avoid the twin traps of Overfitting and Underfitting. Next Episode: We look at the tools of the trade in Machine Learning Libraries.

E11. An Overview of Generative AI

Episode 11: An Overview of Generative AI It’s the topic everyone is talking about. In this episode, we broaden our scope from NLP to the entire field of Generative AI—the technology that creates original text, images, code, and audio from a simple prompt. In this episode, we cover: * The Surge: How ChatGPT thrust AI into the headlines and what analysts predict for 2026. * The 3 Phases: * Training: Building massive Foundation Models on petabytes of data. * Tuning: Customizing via Fine-Tuning and RLHF (Human Feedback). * Generation: Using RAG (Retrieval Augmented Generation) to access live data. * The Architectures: A history of VAEs, GANs, Diffusion Models (like DALL-E), and the game-changing Transformers. * The Risks: Tackling Hallucinations, Deepfakes, and the "Black Box" problem. Next Episode: We drill down into the mechanics of Model Training.

E10. An Overview of Natural Language Processing

Episode 10: An Overview of Natural Language Processing If Computer Vision allows machines to "see," Natural Language Processing (NLP) allows them to "understand." In this episode, we explore the science behind how computers communicate, from old-school spellcheckers to the Transformers powering ChatGPT. In this episode, we cover: * The Evolution: From rigid Rules-Based systems to Statistical N-Grams and today’s Deep Learning models. * The Pipeline: How raw text is transformed via Tokenization, Lemmatization, and Word Embeddings (like Word2Vec). * Key Tasks: * Named Entity Recognition (NER): Identifying people and places. * Sentiment Analysis: Reading emotions and sarcasm. * Coreference Resolution: Figuring out who "she" refers to. * The Hurdles: Why Ambiguity, Slang, and Tone of Voice remain difficult for AI to master. Next Episode: We take the next logical step into the world of Generative AI.
