Linear Regression clearly explained ๐๐ป
Linear regression is the simplest statistical regression method used for predictive analysis.
It can be performed with multiple variables.... but today we'll focus on a single one.
The Encoder is the part responsible for processing input tokens through self-attention and feed-forward layers to generate context-aware representations.
๐ Itโs the powerhouse behind understanding sequences in NLP models.

SQL Joins clearly explained ๐๐ป
1๏ธโฃ ๐๐ฒ๐ณ๐ ๐๐ผ๐ถ๐ป
Left Join returns all records from the left table (A) and the matched records from the right table (B). If there's no match, the result is NULL on the right side.
๐กThink of it as keeping all items in A and filling gaps from B where they exist.
