How to make your LLMs smarter and more efficient explained!👇🏻

(Don't forget to bookmark for later 😉) Creating an LLM demo is a breeze.
But... refining it for production? That's where the real challenge begins! 🛠️

Teams often grapple with LLMs lacking deep knowledge or delivering inaccurate outputs.

How do we fix this?

Multiple-class Logistic Regression clearly explained 👇🏻

(Don't forget to bookmark for later! 😉) By default, Logistic Regression is like a coin toss - heads or tails, A or B.

But what if you have multiple classes?

That's where we adapt our model for MULTIPLE CHOICES!
There are two main ways:

Simple Linear Regression exemplified for dummies👇🏻

We're using height and weight - a classic duo often assumed to have a linear relationship.

But assumptions in data science? No way! 🧐

Let's find out:
- Do height and weight really share a linear bond?

Linear Regression clearly explained 👇🏻 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.

Also known as Simple Linear Regression.

The Transformer's encoder clearly explained 👇🏻 1️⃣ 𝗪𝗛𝗔𝗧'𝗦 𝗧𝗛𝗘 𝗘𝗡𝗖𝗢𝗗𝗘𝗥? 🧠

The Encoder is the part responsible for processing input tokens through self-attention and feed-forward layers to generate context-aware representations.

👉 It’s the powerhouse behind understanding sequences in NLP models.

It is a binary classification model used to classify our input data into two main categories.

It can be extended to multiple classifications... but today we'll focus on a binary one.

Also known as Simple Logistic Regression.

We use a dummy table with the salary of employees depending on their field and experience,

🎯 Our main goal?
Understand the field that earns the most.

Ever felt confused by SQL's execution flow? 🤔

Then you better stay with me!

What is geospatial data, how is it represented, and why does it matter?

Let’s break it down 🧵👇 1️⃣ 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗚𝗲𝗼𝘀𝗽𝗮𝘁𝗶𝗮𝗹 𝗗𝗮𝘁𝗮?
Geospatial data refers to information tied to specific geographic locations on Earth’s surface.

Think of:
- Maps 🗺️
- Addresses 🏠
- Satellite images 🛰️
- Coordinates 📍

It’s the foundation of navigation apps, urban planning, and more! 🌐

🚀 New to SQL?

Here’s a roadmap to get you started, step-by-step! 🧵👇

Before diving deep, it's essential to grasp what is SQL.

Begin with:
• What is a Relational Database?
• Comparing SQL and NoSQL Databases
• Understanding SQL Syntax and Basic Commands

How Python work in our computer clearly explained👇🏻 1️⃣ 𝗠𝗲𝗺𝗼𝗿𝘆 𝗦𝗵𝗲𝗹𝘃𝗲𝘀: 𝗪𝗵𝗲𝗿𝗲 𝗣𝘆𝘁𝗵𝗼𝗻 𝗦𝘁𝗼𝗿𝗲𝘀 𝗗𝗮𝘁𝗮
Imagine your computer's memory as a vast warehouse of shelves.

Each byte is a slot on these shelves.

Python, with your OS's permission, uses this space for its data and code. 🏢

Today let's learn SQL's execution order and its importance 👇🏻 1️⃣ 𝗦𝗤𝗟 𝗔𝗦 𝗔 𝗗𝗘𝗖𝗟𝗔𝗥𝗔𝗧𝗜𝗩𝗘 𝗟𝗔𝗡𝗚𝗨𝗔𝗚𝗘
𝘠𝘰𝘶 𝘵𝘦𝘭𝘭 𝘪𝘵 𝘸𝘩𝘢𝘵 𝘺𝘰𝘶 𝘸𝘢𝘯𝘵, 𝘯𝘰𝘵 𝘩𝘰𝘸 𝘵𝘰 𝘥𝘰 𝘪𝘵.

So SQL expects statements to be written in a specific order ...

but their evaluation sequence differs.

SQL Joins clearly explained 👇🏻 1️⃣ 𝗟𝗲𝗳𝘁 𝗝𝗼𝗶𝗻
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.

💡Think of it as keeping all items in A and filling gaps from B where they exist.

Are you the one crafting charts to communicate your data?

Then you better stay with me! 🤓

Today let's dive into visual encoding and their key role in DataViz! 👇🏻 Charts are composed of two core components:
- Data
- Visuals

But how do we convert this data into a visual representation?

Say hi to visual encodings! 👋🏻

Struggling to craft effective charts? 🤔📊

Let's understand 𝘄𝗵𝘆 some charts are 𝗶𝗻𝘁𝘂𝗶𝘁𝗶𝘃𝗲 👇🏻 Think of DataViz as your GPS in the world of numbers.

It turns complex data into clear, actionable insights.

But... why do some charts enlighten us while others don't?

The Gestalt Theory explains how our brains perceive patterns and how to take advantage of them.

Struggling to craft clear charts? 🤔📊

Let's understand why some charts are misleading and how to avoid it 👇🏻 First things first, ever heard of the term "ink" in data visualization?

It's not about the ink in your pen.

It refers to any part of a visualization that stands out from the background.

Think lines, bars, points, and even text. 🖋️
