Are you looking to become a machine learning engineer? ๐Ÿค–
The algorithm brought you to the right place! ๐Ÿš€

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

๐Ÿ“š Math & Statistics
Just like most other data roles, machine learning engineering starts with strong foundations from math, especially in linear algebra, probability, and statistics. Hereโ€™s what you need to focus on:

- Basic probability concepts ๐ŸŽฒ
- Inferential statistics ๐Ÿ“Š
- Regression analysis ๐Ÿ“ˆ
- Experimental design & A/B testing ๐Ÿ”
- Bayesian statistics ๐Ÿ”ข
- Calculus ๐Ÿงฎ
- Linear algebra ๐Ÿ” 

๐Ÿ 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 โœ๏ธ
- Control flow statements (e.g., if-else, loops) ๐Ÿ”„
- Functions and modules ๐Ÿ”ง
- Error handling and exceptions โŒ
- Basic data structures (e.g., lists, dictionaries, tuples) ๐Ÿ—‚๏ธ
- Object-oriented programming concepts ๐Ÿงฑ
- Basic work with APIs ๐ŸŒ
- Detailed data structures and algorithmic thinking ๐Ÿง 

๐Ÿงช Machine Learning Prerequisites
- Exploratory Data Analysis (EDA) with NumPy and Pandas ๐Ÿ”
- Data visualization techniques to visualize variables ๐Ÿ“‰
- Feature extraction & engineering ๐Ÿ› ๏ธ
- Encoding data (different types) ๐Ÿ”

โš™๏ธ Machine Learning Fundamentals
Use the scikit-learn library along with other Python libraries for:

- Supervised Learning: Linear Regression, K-Nearest Neighbors, Decision Trees ๐Ÿ“Š
- Unsupervised Learning: K-Means Clustering, Principal Component Analysis, Hierarchical Clustering ๐Ÿง 
- Reinforcement Learning: Q-Learning, Deep Q Network, Policy Gradients ๐Ÿ•น๏ธ

Solve two types of problems:
- Regression ๐Ÿ“ˆ
- Classification ๐Ÿงฉ

๐Ÿง  Neural Networks
Neural networks are like computer brains that learn from examples ๐Ÿง , 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 ๐Ÿ”„
- Convolutional Neural Networks (CNNs): Great for images, learning visual patterns ๐Ÿ–ผ๏ธ
- Recurrent Neural Networks (RNNs): Good for sequences like text or time series ๐Ÿ“š

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

๐Ÿ•ธ๏ธ Deep Learning
Deep learning is a subset of machine learning that can learn unsupervised from data that is unstructured or unlabeled.

- CNNs ๐Ÿ–ผ๏ธ
- RNNs ๐Ÿ“
- LSTMs โณ

๐Ÿš€ 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 ๐Ÿ—ƒ๏ธ
- Automated Testing and Continuous Integration (CI) ๐Ÿ”„
- Continuous Delivery and Deployment (CD) ๐Ÿšš
- Monitoring and Logging ๐Ÿ–ฅ๏ธ
- Experiment Tracking and Management ๐Ÿงช
- Feature Stores ๐Ÿ—‚๏ธ
- Data Pipeline and Workflow Orchestration ๐Ÿ› ๏ธ
- Infrastructure as Code (IaC) ๐Ÿ—๏ธ
- Model Serving and APIs ๐ŸŒ

โœจThe STAR method is a powerful technique used to answer behavioral interview questions effectively.

It helps structure responses by focusing on Situation, Task, Action, and Result. For analytics professionals, using the STAR method ensures that you demonstrate your problem-solving abilities, technical skills, and business acumen in a clear and concise way.

Hereโ€™s how the STAR method works, tailored for an analytics interview:

๐Ÿ“ 1. Situation
Describe the context or challenge you faced. For analysts, this might be related to data challenges, business processes, or system inefficiencies. Be specific about the setting, whether it was a project, a recurring task, or a special initiative.

Example: โ€œAt my previous role as a data analyst at XYZ Company, we were experiencing a high churn rate among our subscription customers. This was a critical issue because it directly impacted revenue.โ€*

๐Ÿ“ 2. Task
Explain the responsibilities you had or the goals you needed to achieve in that situation. In analytics, this usually revolves around diagnosing the problem, designing experiments, or conducting data analysis.

Example: โ€œI was tasked with identifying the factors contributing to customer churn and providing actionable insights to the marketing team to help them improve retention.โ€*

๐Ÿ“ 3. Action
Detail the specific actions you took to address the problem. Be sure to mention any tools, software, or methodologies you used (e.g., SQL, Python, data #visualization tools, #statistical #models). This is your opportunity to showcase your technical expertise and approach to problem-solving.

Example: โ€œI collected and analyzed customer data using #SQL to extract key trends. I then used #Python for data cleaning and statistical analysis, focusing on engagement metrics, product usage patterns, and customer feedback. I also collaborated with the marketing and product teams to understand business priorities.โ€*

๐Ÿ“ 4. Result
Highlight the outcome of your actions, especially any measurable impact. Quantify your results if possible, as this demonstrates your effectiveness as an analyst. Show how your analysis directly influenced business decisions or outcomes.

Example: โ€œAs a result of my analysis, we discovered that customers were disengaging due to a lack of certain product features. My insights led to a targeted marketing campaign and product improvements, reducing churn by 15% over the next quarter.โ€*

Example STAR Answer for an Analytics Interview Question:
Question: *"Tell me about a time you used data to solve a business problem."*

Answer (STAR format): 
๐Ÿ”ป*S*: โ€œAt my previous company, our sales team was struggling with inconsistent performance, and management wasnโ€™t sure which factors were driving the variance.โ€ 
๐Ÿ”ป*T*: โ€œI was assigned the task of conducting a detailed analysis to identify key drivers of sales performance and propose data-driven recommendations.โ€ 
๐Ÿ”ป*A*: โ€œI began by collecting sales data over the past year and segmented it by region, product line, and sales representative. I then used Python for #statistical #analysis and developed a regression model to determine the key factors influencing sales outcomes. I also visualized the data using #Tableau to present the findings to non-technical stakeholders.โ€ 
๐Ÿ”ป*R*: โ€œThe analysis revealed that product mix and regional seasonality were significant contributors to the variability. Based on my findings, the company adjusted their sales strategy, leading to a 20% increase in sales efficiency in the next quarter.โ€

Hope this helps you ๐Ÿ˜Š

10 DAX Functions Every Power BI Learner Should Know!



1. SUM
   Scenario: Calculate the total sales amount.
   DAX Formula: Total Sales = SUM(Sales[SalesAmount])

2. AVERAGE
   Scenario: Find the average sales per transaction.
   DAX Formula: Average Sales = AVERAGE(Sales[SalesAmount])

3. COUNTROWS
   Scenario: Count the number of transactions.
   DAX Formula: Transaction Count = COUNTROWS(Sales)

4. DISTINCTCOUNT
   Scenario: Count the number of unique customers.
   DAX Formula: Unique Customers = DISTINCTCOUNT(Sales[CustomerID])

5. CALCULATE
   Scenario: Calculate the total sales for a specific product category.
   DAX Formula: Total Sales (Category) = CALCULATE(SUM(Sales[SalesAmount]), Products[Category] = "Electronics")

6. FILTER
   Scenario: Calculate the total sales for transactions above a certain amount.
   DAX Formula: High Value Sales = CALCULATE(SUM(Sales[SalesAmount]), FILTER(Sales, Sales[SalesAmount] > 1000))

7. IF
   Scenario: Create a calculated column to categorize transactions as "High" or "Low" based on sales amount.
   DAX Formula: Transaction Category = IF(Sales[SalesAmount] > 500, "High", "Low")

8. RELATED
   Scenario: Fetch product names from the Products table into the Sales table.
   DAX Formula: Product Name = RELATED(Products[ProductName])

9. YEAR
   Scenario: Extract the year from the transaction date.
   DAX Formula: Transaction Year = YEAR(Sales[TransactionDate])

10. DATESYTD
    Scenario: Calculate year-to-date sales.
    DAX Formula: YTD Sales = TOTALYTD(SUM(Sales[SalesAmount]), Sales[TransactionDate])
