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, especially in linear algebra, probability, and statistics. Here’s what you need to focus on:

- Basic probability concepts 🎲
- Inferential statistics 📊
- Regression analysis 📈
- Experimental design & 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 🔍
- Data visualization techniques to visualize variables 📉
- Feature extraction & engineering 🛠️
- Encoding data (different types) 🔐

⚙️ Machine Learning Fundamentals
Use the scikit-learn library along 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 🕹️

Solve 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 📚

In Python, use TensorFlow and Keras, as well as PyTorch for more complex neural network systems.

🕸️ Deep Learning
Deep learning is a subset of machine learning that can learn unsupervised from data that is unstructured or unlabeled.

- CNNs 🖼️
- RNNs 📝
- LSTMs ⏳

🚀 Machine Learning Project Deployment

Machine learning engineers should dive into MLOps and project deployment.

Here are the must-have skills:

- Version Control for Data and Models 🗃️
- Automated Testing and Continuous Integration (CI) 🔄
- Continuous Delivery and Deployment (CD) 🚚
- Monitoring and Logging 🖥️
- Experiment Tracking and Management 🧪

What are the main assumptions of linear regression?

There are several assumptions of linear regression. If any of them is violated, model predictions and interpretation may be worthless or misleading.

1) Linear relationship between features and target variable.

2) Additivity means that the effect of changes in one of the features on the target variable does not depend on values of other features. For example, a model for predicting revenue of a company have of two features - the number of items a sold and the number of items b sold. When company sells more items a the revenue increases and this is independent of the number of items b sold. But, if customers who buy a stop buying b, the additivity assumption is violated.

3) Features are not correlated (no collinearity) since it can be difficult to separate out the individual effects of collinear features on the target variable.

4) Errors are independently and identically normally distributed (yi = B0 + B1*x1i + ... + errori):

i) No correlation between errors (consecutive errors in the case of time series data).

ii) Constant variance of errors - homoscedasticity. For example, in case of time series, seasonal patterns can increase errors in seasons with higher activity.

iii) Errors are normaly distributed, otherwise some features will have more influence on the target variable than to others. If the error distribution is significantly non-normal, confidence intervals may be too wide or too narrow.

Data Science Interview Questions

1. What are the different subsets of SQL?

Data Definition Language (DDL) – It allows you to perform various operations on the database such as CREATE, ALTER, and DELETE objects.
Data Manipulation Language(DML) – It allows you to access and manipulate data. It helps you to insert, update, delete and retrieve data from the database.
Data Control Language(DCL) – It allows you to control access to the database. Example – Grant, Revoke access permissions.

2. List the different types of relationships in SQL.

There are different types of relations in the database:
One-to-One – This is a connection between two tables in which each record in one table corresponds to the maximum of one record in the other.
One-to-Many and Many-to-One – This is the most frequent connection, in which a record in one table is linked to several records in another.
Many-to-Many – This is used when defining a relationship that requires several instances on each sides.
Self-Referencing Relationships – When a table has to declare a connection with itself, this is the method to employ.

3. How to create empty tables with the same structure as another table?

To create empty tables:
Using the INTO operator to fetch the records of one table into a new table while setting a WHERE clause to false for all entries, it is possible to create empty tables with the same structure. As a result, SQL creates a new table with a duplicate structure to accept the fetched entries, but nothing is stored into the new table since the WHERE clause is active.

4. What is Normalization and what are the advantages of it?

Normalization in SQL is the process of organizing data to avoid duplication and redundancy. Some of the advantages are:
Better Database organization
More Tables with smaller rows
Efficient data access
Greater Flexibility for Queries
Quickly find the information
Easier to implement Security
