Algorithms and Data Structures Cheat Sheet An algorithm is a set of steps for solving a specific problem, while a data structure is a method for organizing and storing data in a computer so that it can be accessed and modified efficiently. This cheat sheet provides a summary of key concepts...
Data Visualization Cheat Sheet Descriptive Statistics Cheat Sheet A collection of data literacy cheat sheets Conclusion In a data-driven world, data literacy is no longer just a desirable skill; it's a necessity. As we've discussed throughout this article, data literacy is vital at both an ind...
Editor's note: For the full scope of cheat sheets included in this 2 part series, please seeThe Complete Collection of Data Science Cheat Sheets - Part 1. Searching for the cheat sheet that works for you can take some time as most of them are not easy to comprehend. The blog contains ...
Let’s get our hands dirty with some code and terminal commands! We will set up a simple project structure that mimics a real-world scenario and get a sense of how to use DVC commands. 1. DVC installation and initialization First, create a new virtual environment, preferably with Conda, ...
Increased Complexity: The process of normalization can introduce complexity in designing and maintaining the database structure. Join Operations: Normalization often leads to the need for join operations to retrieve data from multiple tables, which can impact query performance. Overnormalization: Overnormal...
redundancies we remove have nothing to do with trying to save space. Instead, the desire is to prevent maintenance anomalies. The normalization process involves stepping through the evaluation of normal forms that decompose a data structure into multiple structures based on the needs of these normal...

Models trained on next-token prediction (where a model just predicts the next work when forming a sentence) are statistically powerful but sample inefficiently.Time is wasted processing low-impact tokens, and the localized process does not consider the global structure.For example, such a model mi...

A Stack is a linear data structure that adheres to a specific order for its operations. This order can be LIFO (Last In First Out) or FILO (First In Last Out). The complexity of the Stack as a data structure arises from its implementation, utilizing other data structures like Arrays, ...
