This is Day1 of my Machine Learning 10 Day Sprint.
Today’s topic: Classical Machine Learning
Core Concept: Moving from “Explicit Programming” (if/else) to “Pattern Recognition” (weights/biases).
Today’s Reading Material:
Machine Learning is Fun! Part 1 by Adam Geitgey.
Why?
It’s a legendary primer that builds the intuition of “estimation” and “cost functions” without drowning you in calculus.
Goal: Explain how a model “learns” a line to separate data.
Deep Dive Question:
Many developers view Classical ML as “outdated” compared to LLMs. However, they share the same DNA: Optimiazation.
As you read, focus on this: If Linear Regression is a “Global” learner (trying to fix one rule to all data) and KNN is a “Local” learner (looking only at immediate neighbors), in what specific real-world scenarios would a “Global” model fail where a “Local” one succeeds?
Notes from the Post
- Cost Function (Math that tells the model is wrong.)
- Optimizer (Math that tells how to get better.)
Takeaway from the Post
- Briefly define the difference between Regression & Classification.
- Answer the question to the Deep Dive Question above.
- Bias-Variance Tradeoff
