DANormalization vs Standardization: When to use what 🎯
━━━━━━━━━━━━━━━━━━━━
NORMALIZATION (0-1 scaling):
Use when:
→ Neural networks (bounded inputs better)
→ NO outliers in data
→ Need specific bounded range
Example: Image pixels (0-255) → normalize to (0-1) for CNN
━━━━━━━━━━━━━━━━━━━━
STANDARDIZATION (mean=0, std=1):
Use when:
→ Linear models (LR, SVM, PCA)
→ Distance algorithms (KNN, K-means)
→ HAVE outliers (more robust)
→ Features roughly normally distributed
Example: Customer segmentation with age + income → standardize before K-means
━━━━━━━━━━━━━━━━━━━━
NEITHER needed:
→ Tree-based models (Random Forest, XGBoost)
━━━━━━━━━━━━━━━━━━━━
Senior DS decision process:
1. Check algorithm requirements
2. Look at feature distributions
3. Identify outliers
4. Then decide
This shows you THINK, not just memorize.

VIData preparation is the most underestimated part of LLM training.
Pre-training, supervised fine-tuning, and RL-based alignment —each stage requires completely different data formats and preprocessing strategies.
If you get the data wrong, no model architecture can save you.
My colleagues and I at AWS wrote a detailed blog
• preprocessing techniques
• scalable data pipelines
• prompt–response formatting
• preference data for alignment
• synthetic data generation (with code examples)

RA"Normalization is the process of organizing a relational database to minimize data redundancy and improve data integrity."
In a production environment, we typically aim for 3rd Normal Form (3NF):
1. 1NF (Atomicity): Each cell contains a single value (no lists).
2. 2NF (No Partial Dependency): All data must depend on the entire Primary Key.
3. 3NF (No Transitive Dependency): Non-key columns should not depend on other non-key columns. (Data depends on "The Key, the whole Key, and nothing but the Key").
In short: It’s about structuring data efficiently so that when a piece of information changes, we only have to update it in one place.
However, it is a trade-off. While normalization optimizes for writing data and saving space, highly normalized databases can be slower for reading because of complex joins. In read-heavy systems (like Data Warehouses), we sometimes intentionally 'denormalize' for performance.
Let's try to understand with a real life example.
### 📲 The Simple Normalization Fix: Address Redundancy
Here is how we use normalization to stop repeating addresses, using the contact list example:
---
#### 🗑️ The Problem: One Messy List (Unnormalized)
You have one giant table where Aunt Sue's address is written multiple times, wasting space.
| Table Name: **CONTACTS\_MESSY** |
| :--- |
| **ContactName** |
| **Phone** |
| **Street Address** |
| **City** |
| **Email** |
---
#### ✨ The Solution: Two Clean Lists (Normalized)
We break the table into two, ensuring each unique address is stored only once.
**1. The Core Contacts List**
This table tracks the person and uses a link (key) to find their address.
| Table Name: **CONTACTS** |
| :--- |
| 🔑 **ContactID (Primary Key)** |
| **ContactName** |
| **Phone** |
| **Email** |
| 🔗 **AddressID (Foreign Key)** |
**2. The Address Lookup List**
This table stores each unique address only once.
| Table Name: **ADDRESSES** |
| :--- |
| 🔑 **AddressID (Primary Key)** |
| **Street Address** |
| **City** |
---
When Aunt Sue moves, you only update the *Street Address* and *City* in *one row* of the *ADDRESSES* table. Every contact linked to that AddressID is instantly updated!
