AI vs ML vs Deep Learning 🤖

You’ve probably seen these 3 terms thrown around like they’re the same thing. They’re not.

AI (Artificial Intelligence): the big umbrella. Anything that makes machines “smart.” Could be rules, could be learning.

ML (Machine Learning): a subset of AI. Machines learn patterns from data instead of being explicitly programmed.

Deep Learning: a subset of ML. Uses neural networks with many layers (deep) powering things like ChatGPT, image recognition, etc.

Think of it this way:
AI = Science
ML = A chapter in the science
Deep Learning = A paragraph in that chapter.

5️⃣ HAVING – Filter groups after aggregation

SELECT department, COUNT(*) FROM employees  
GROUP BY department HAVING COUNT(*) > 5;

6️⃣ LIMIT / TOP – Restrict number of rows 
-- MySQL/PostgreSQL

SELECT * FROM sales LIMIT 10;

-- SQL Server

SELECT TOP 10 * FROM sales;

7️⃣ DISTINCT – Remove duplicates

SELECT DISTINCT city FROM customers;

8️⃣ BETWEEN – Filter within a range

✅ Data Scientists in Your 20s – Avoid This Trap 🚫🧠

🎯 The Trap? → Passive Learning 
Feels like you’re learning but not truly growing.

🔍 Example:
⦁ Watching endless ML tutorial videos
⦁ Saving notebooks without running or understanding
⦁ Joining courses but not coding models
⦁ Reading research papers without experimenting

End result? 
❌ No models built from scratch 
❌ No real data cleaning done 
❌ No insights or reports delivered

This is passive learning — absorbing without applying. It builds false confidence and slows progress.

🛠️ How to Fix It: 
1️⃣ Learn by doing: Grab real datasets (Kaggle, UCI, public APIs) 
2️⃣ Build projects: Classification, regression, clustering tasks 
3️⃣ Document findings: Share explanations like you’re presenting to stakeholders 
4️⃣ Get feedback: Post code & reports on GitHub, Kaggle, or LinkedIn 
5️⃣ Fail fast: Debug models, tune hyperparameters, iterate frequently

📌 In your 20s, build practical data intuition — not just theory or certificates.

Stop passive watching. 
Start real modeling. 
Start storytelling with data.

That’s how data scientists grow fast in the real world! 🚀

💬 Tap ❤️ if this resonates with you!

Are you looking to become a machine learning engineer? The algorithm brought you to the right place! 📌

I created a free and comprehensive roadmap. Let's go through this thread and explore what you need to know to become an expert machine learning engineer:

Math & Statistics

Just like most other data roles, machine learning engineering starts with strong foundations from math, precisely linear algebra, probability and statistics.

Here are the probability units you will need to focus on:

Basic probability concepts statistics
Inferential statistics
Regression analysis
Experimental design and A/B testing Bayesian statistics
Calculus
Linear algebra

Python:

You can choose Python, R, Julia, or any other language, but Python is the most versatile and flexible language for machine learning.

Variables, data types, and basic operations
Control flow statements (e.g., if-else, loops)
Functions and modules
Error handling and exceptions
Basic data structures (e.g., lists, dictionaries, tuples)
Object-oriented programming concepts
Basic work with APIs
Detailed data structures and algorithmic thinking

Machine Learning Prerequisites:

Exploratory Data Analysis (EDA) with NumPy and Pandas
Basic data visualization techniques to visualize the variables and features.
Feature extraction
Feature engineering
Different types of encoding data

Machine Learning Fundamentals

Using scikit-learn library in combination with other Python libraries for:

Supervised Learning: (Linear Regression, K-Nearest Neighbors, Decision Trees)
Unsupervised Learning: (K-Means Clustering, Principal Component Analysis, Hierarchical Clustering)
Reinforcement Learning: (Q-Learning, Deep Q Network, Policy Gradients)

Solving two types of problems:
Regression
Classification

Neural Networks:
Neural networks are like computer brains that learn from examples, made up of layers of "neurons" that handle data. They learn without explicit instructions.

Types of Neural Networks:

Feedforward Neural Networks: Simplest form, with straight connections and no loops.
Convolutional Neural Networks (CNNs): Great for images, learning visual patterns.
Recurrent Neural Networks (RNNs): Good for sequences like text or time series, because they remember past information.

In Python, it’s the best to use TensorFlow and Keras libraries, as well as PyTorch, for deeper and more complex neural network systems.

Deep Learning:

Deep learning is a subset of machine learning in artificial intelligence (AI) that has networks capable of learning unsupervised from data that is unstructured or unlabeled.

Convolutional Neural Networks (CNNs)
Recurrent Neural Networks (RNNs)
Long Short-Term Memory Networks (LSTMs)
Generative Adversarial Networks (GANs)
Autoencoders
Deep Belief Networks (DBNs)
Transformer Models

Machine Learning Project Deployment

Machine learning engineers should also be able to dive into MLOps and project deployment. Here are the things that you should be familiar or skilled at:

Version Control for Data and Models
Automated Testing and Continuous Integration (CI)
Continuous Delivery and Deployment (CD)
Monitoring and Logging
Experiment Tracking and Management
Feature Stores
Data Pipeline and Workflow Orchestration
Infrastructure as Code (IaC)
Model Serving and APIs

✅ Data Science Mistakes Beginners Should Avoid ⚠️📉

1️⃣ Skipping the Basics
• Jumping into ML without Python, Stats, or Pandas
✅ Build strong foundations in math, programming & EDA first

2️⃣ Not Understanding the Problem
• Applying models blindly
• Irrelevant features and metrics
✅ Always clarify business goals before coding

3️⃣ Treating Data Cleaning as Optional
• Training on dirty/incomplete data
✅ Spend time on preprocessing — it’s 70% of real work

4️⃣ Using Complex Models Too Early
• Overfitting small datasets
• Ignoring simpler, interpretable models
✅ Start with baseline models (Logistic Regression, Decision Trees)

5️⃣ No Evaluation Strategy
• Relying only on accuracy
✅ Use proper metrics (F1, AUC, MAE) based on problem type

6️⃣ Not Visualizing Data
• Missed outliers and patterns
✅ Use Seaborn, Matplotlib, Plotly for EDA

7️⃣ Poor Feature Engineering
• Feeding raw data into models
✅ Create meaningful features that boost performance

8️⃣ Ignoring Domain Knowledge
• Features don’t align with real-world logic
✅ Talk to stakeholders or do research before modeling

9️⃣ No Practice with Real Datasets
• Kaggle-only learning
✅ Work with messy, real-world data (open data portals, APIs)

🔟 Not Documenting or Sharing Work
• No GitHub, no portfolio
✅ Document notebooks, write blogs, push projects online
