We recently had a request from for Unsupervised Learning notes.

To make this resource even more valuable for everyone, we decided to bundle them together with Supervised Learning notes as well!

✅ The Most Underrated Habit in Data Science

👉 Keep a modeling journal.

After every experiment, write down:

• What changed
• Why you changed it
• The metric before
• The metric after
• What you learned

Six months later, this notebook becomes more valuable than your code.

🚩7 Red Flags You Should Check in Every Dataset

Before EDA, look for these.

🔻Duplicate rows
🔻Missing values that aren't random
🔻Impossible numbers (negative ages, future dates)
🔻Columns with only one value
🔻Categories with inconsistent spelling
🔻Target leakage
🔻Suspiciously perfect distributions

Catching these early saves hours of debugging later.

🧠 LLM Wiki

LLM Wiki is a concept by Andrej Karpathy for maintaining a continuously evolving Markdown knowledge base instead of relying only on document retrieval. As information is processed, related topics are organized into linked wiki pages, making knowledge easier to navigate, update, and reuse over time.

This is a thoughtful read if you're interested in how long-term knowledge systems for LLMs could evolve.

Why Learning Rate Can Make or Break Training

Think of gradient descent as walking downhill. The learning rate controls your step size.

Too small? You'll eventually reach the bottom. It just takes forever.
Too large? You'll keep overshooting the minimum.

Sometimes you'll bounce back and forth without ever converging.
That's why training loss can suddenly explode.

Not because your model is bad.
Because your optimizer is taking steps that are simply too big. The goal isn't the fastest movement. It's stable progress.

👉 Takeaway: When loss behaves unpredictably, learning rate should be one of the first things you investigate.

❔Why Batch Normalization Makes Deep Networks Easier to Train

Training a deep network is a bit like passing a message through twenty people. If each person changes the message slightly, by the end it's completely different.

The same thing happens inside neural networks.

As earlier layers update, the distribution of values reaching later layers keeps changing.
Every layer has to constantly readjust.

Batch Normalization reduces this problem by normalizing each mini-batch during training.
That gives later layers a more stable input distribution.

✅ The result?
• Faster convergence
• Higher learning rates
• Less sensitivity to initialization
• Better training stability

✅ Before Building Any Model, Answer These 5 Questions

A surprising number of ML projects fail before training even begins.

Before writing a single line of code, answer these:

1. What decision will this prediction help someone make?
2. What data won't exist when this model is deployed?
3. What's the cost of a wrong prediction?
4. Which metric actually reflects that cost?
5. How will success be measured six months from now?

Most modeling mistakes start here, not in the code.
