If I had to start learning data analyst all over again, I'd follow this:

1- Learn SQL:

---- Joins (Inner, Left, Full outer and Self)
---- Aggregate Functions (COUNT, SUM, AVG, MIN, MAX)
---- Group by and Having clause
---- CTE and Subquery
---- Windows Function (Rank, Dense Rank, Row number, Lead, Lag etc)

2- Learn Excel:

---- Mathematical (COUNT, SUM, AVG, MIN, MAX, etc)
---- Logical Functions (IF, AND, OR, NOT)
---- Lookup and Reference (VLookup, INDEX, MATCH etc)
---- Pivot Table, Filters, Slicers

3- Learn BI Tools:

---- Data Integration and ETL (Extract, Transform, Load)

This is a quick and easy guide to the four main categories: Supervised, Unsupervised, Semi-Supervised, and Reinforcement Learning.

1. Supervised Learning
In supervised learning, the model learns from examples that already have the answers (labeled data). The goal is for the model to predict the correct result when given new data.

Some common supervised learning algorithms include:

โžก๏ธ Linear Regression โ€“ For predicting continuous values, like house prices.
โžก๏ธ Logistic Regression โ€“ For predicting categories, like spam or not spam.
โžก๏ธ Decision Trees โ€“ For making decisions in a step-by-step way.
โžก๏ธ K-Nearest Neighbors (KNN) โ€“ For finding similar data points.
โžก๏ธ Random Forests โ€“ A collection of decision trees for better accuracy.
โžก๏ธ Neural Networks โ€“ The foundation of deep learning, mimicking the human brain.

2. Unsupervised Learning
With unsupervised learning, the model explores patterns in data that doesnโ€™t have any labels. It finds hidden structures or groupings.

Some popular unsupervised learning algorithms include:

โžก๏ธ K-Means Clustering โ€“ For grouping data into clusters.
โžก๏ธ Hierarchical Clustering โ€“ For building a tree of clusters.
โžก๏ธ Principal Component Analysis (PCA) โ€“ For reducing data to its most important parts.
โžก๏ธ Autoencoders โ€“ For finding simpler representations of data.

3. Semi-Supervised Learning
This is a mix of supervised and unsupervised learning. It uses a small amount of labeled data with a large amount of unlabeled data to improve learning.

Common semi-supervised learning algorithms include:

โžก๏ธ Label Propagation โ€“ For spreading labels through connected data points.
โžก๏ธ Semi-Supervised SVM โ€“ For combining labeled and unlabeled data.
โžก๏ธ Graph-Based Methods โ€“ For using graph structures to improve learning.

4. Reinforcement Learning
In reinforcement learning, the model learns by trial and error. It interacts with its environment, receives feedback (rewards or penalties), and learns how to act to maximize rewards.

Popular reinforcement learning algorithms include:

โžก๏ธ Q-Learning โ€“ For learning the best actions over time.
โžก๏ธ Deep Q-Networks (DQN) โ€“ Combining Q-learning with deep learning.
โžก๏ธ Policy Gradient Methods โ€“ For learning policies directly.
โžก๏ธ Proximal Policy Optimization (PPO) โ€“ For stable and effective learning.
