The goal of this group is to help you navigate the complex and rapidly evolving world of data science and artificial intelligence. This is your hub to stay up-to-date on the latest trends, learn specialized skills to turn raw data into valuable insights, connect with a community of like-minded individuals, and ultimately, become a Data Alchemist. Together, let's decode the language of data and shape a future where knowledge and community illuminate our way.

This is a great video on a systematic approach to comparing model performance. https://www.youtube.com/watch?v=VC6QCEXERpU

If you’re a developer, you’ve probably seen Cursor IDE making waves recently. It’s been everywhere, and after five years with VS Code, I made the switch — for now. Cursor is a fork of VS Code but adds powerful AI features like autocomplete, inline edits, and a composer. If you’re familiar with VS Code, the transition is seamless. So you can still use all your settings, themes, extensions, and most importantly, the interactive window! In this week’s video, I dive into these AI features, show how they can improve your coding workflow, and help you decide if Cursor is right for you. Talk soon, Dave P.S. We’ve temporarily closed enrollment for Data Freelancer as we’ve hit our capacity. But don’t worry — some exciting updates are coming soon. We're working on some big things behind the scenes for both Datalumina as a company and the Data Freelancer program. Stay tuned for more details!

Hello everyone! this is my first post on this community so i am really sorry if i did something wrong :) Today i just finished Phyton Fundamentals from kaggle that the Classroom recommended and actually, before this i have already done some Phyton course from learnphyton.org. But even after i finish both of this Phyton course i still feels like there is something that's not right in me. Everytime i do an exercise that the course provide if the exercise is too hard i ended up just going for the hint or asking ChatGPT for help or even worse just going straight into the solution. Which make me feels like i haven't really mastered the basics of Phyton. Well, that is my problem right now, i planned to just go forward and continuing the Classroom right now but if any you have insights/tips/recommendations to be shared with me, it will be really helpful and appreciated. Thanks for reading this post.

I am going through Dave's Introduction to Classes video (https://www.youtube.com/watch?v=u4Ryk0YuW6A). I am a javascript / typescript guy, so python is somewhat new to me. I am using CodiumAI in vscode (the free version), and I wanted to see if it could create a list of questions to help me learn about Python classes and reinforce my understanding. Here is what it came up with. (The point of this post is to encourage you all to start exploring new ways to learn whatever it is you are trying to learn!) Python Classes Quiz 1. Basic Class Definition - What is a class in Python, and how do you define one? - Write a simple class named Car with an attribute color. 2. Class Attributes and Methods - What is the difference between a class attribute and an instance attribute? - How do you define a method inside a class? - Create a class Dog with an instance attribute name and a method bark that prints "Woof!". 3. The __init__ Method - What is the purpose of the __init__ method in a class? - How do you initialize an instance attribute in the __init__ method? - Write a class Book with attributes title and author, and initialize them using the __init__ method. 4. Creating and Using Instances - How do you create an instance of a class? - Given a class Person with an attribute name, how would you create an instance named john with the name "John Doe"? 5. Inheritance - What is inheritance in the context of Python classes? - How do you create a subclass that inherits from a superclass? - Create a class Animal with a method speak, and a subclass Cat that overrides the speak method to print "Meow!". 6. Encapsulation - What is encapsulation, and how is it implemented in Python? - How can you make an attribute private in a Python class? - Modify the Car class to include a private attribute _mileage. 7. Polymorphism - What is polymorphism in Python, and how does it relate to classes? - Provide an example of polymorphism using a method describe in two different classes.
