Essential Math for AI and ML: A Beginner's Introduction to Linear Algebra

Linear algebra is the language machine learning models actually think in — vectors, matrices, and the operations between them are how data, weights, and embeddings get represented and transformed. This is where our AI math journey starts, working through the concepts that show up everywhere from a simple neural network layer to the attention mechanism inside an LLM.

CCAR-F Domain 1: Agentic Architecture & Orchestration

I'm preparing for CCAR-F Domain 1: Agentic Architecture & Orchestration, the largest domain at 27% of the exam. We'll break down what Anthropic expects us to understand about agentic loops, multi-agent orchestration, subagents, task decomposition, workflows, Agent SDK hooks, and session management — in plain English, with examples, illustrations, hands-on experiments, and the architectural trade-offs that actually matter.

How I'm Preparing for the Claude Certified Architect – Foundations Exam (CCAR-F)

I'm preparing for the Claude Certified Architect – Foundations (CCAR-F) exam and documenting the journey along the way. I'll break down the 5 exam domains (what we actually need to know), the 6 scenarios (where we'll need to apply it), the exam format and weighting, the free resources I'm using, and my week-by-week preparation plan. All in plain English, with examples, illustrations, and hopefully without making us open 27 browser tabs just to answer one simple question.

Essential Math for AI and ML: Introduction to Estimation Theory

Estimation theory is like the detective work of data science. It equips us with methods to infer unknown parameters from observed data. Imagine estimating the average height in a city or the likelihood of a coin flip. Key techniques like Maximum Likelihood and Bayesian Estimation ensure our guesses are accurate and reliable. Used in fields from economics to engineering, estimation theory transforms raw data into meaningful insights. It’s the art and science of turning observations into actionable knowledge, guiding decisions in everyday life and complex industries alike. Dive into this fascinating world and become a data detective!
