Struggling with Machine Learning algorithms? 🤖

Then you better stay with me! 🤓

We are going back to the basics to simplify ML algorithms.
... today's turn is Logistic Regression! 👇🏻

1️⃣ 𝗟𝗢𝗚𝗜𝗦𝗧𝗜𝗖 𝗥𝗘𝗚𝗥𝗘𝗦𝗦𝗜𝗢𝗡
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.

2️⃣ 𝗛𝗢𝗪 𝗧𝗢 𝗖𝗢𝗠𝗣𝗨𝗧𝗘 𝗜𝗧?
The Sigmoid Function is our mathematical wand, turning numbers into neat probabilities between 0 and 1.

It's what makes Logistic Regression tick, giving us a clear 'probabilistic' picture.

3️⃣ 𝗛𝗢𝗪 𝗧𝗢 𝗗𝗘𝗙𝗜𝗡𝗘 𝗧𝗛𝗘 𝗕𝗘𝗦𝗧 𝗙𝗜𝗧?
For every parametric ML algorithm, we need a LOSS FUNCTION.

It is our map to find our optimal solution or global minimum.

(hoping there is one! 😉)

✚ 𝗕𝗢𝗡𝗨𝗦 - FROM LINEAR TO LOGISTIC REGRESSION
To obtain the sigmoid function, we can derive it from the Linear Regression equation.

Understand the power of Data Lakehouse Architecture for 𝗙𝗥𝗘𝗘 here...


🚨𝗢𝗹𝗱 𝘄𝗮𝘆
• Complicated ETL processes for data integration.
• Silos of data storage, separating structured and unstructured data.
• High data storage and management costs in traditional warehouses.
• Limited scalability and delayed access to real-time insights.

𝗡𝗲𝘄 𝗪𝗮𝘆
• Streamlined data ingestion and processing with integrated SQL capabilities.
• Unified storage layer accommodating both structured and unstructured data.
• Cost-effective storage by combining benefits of data lakes and warehouses.
• Real-time analytics and high-performance queries with SQL integration.

The shift?

Unified Analytics and Real-Time Insights > Siloed and Delayed Data Processing

Leveraging SQL to manage data in a data lakehouse architecture transforms how businesses handle data.

Start from scratch, master advanced concepts, and land your dream job in Data Science! 🎯
Here's what the average data engineering interview looks like:

- 1 hour algorithms in Python
Here you will be asked irrelevant questions about dynamic programming, linked lists, and inverting trees

- 1 hour SQL
Here you will be asked niche questions about recursive CTEs that you've used once in your ten year career

- 1 hour data architecture
Here you will be asked about CAP theorem, lambda vs kappa, and a bunch of other things that ChatGPT probably could answer in a heartbeat

- 1 hour behavioral
Here you will be asked about how to play nicely with your coworkers. This is the most relevant interview in my opinion

- 1 hour project deep dive
Here you will be asked to make up a story about something you did or did not do in the past that was a technical marvel

- 4 hour take home assignment
Here you will be asked to build their entire data engineering stack from scratch over a weekend because why hire data engineers when you can submit them to tests?
