ChatGPT for Data Science Cheat Sheet
ChatGPT (and, indeed, the most robust and latest versions of GPT3) is meant to assist (that’s right… assist!) humans that decide to use it as such, and with a little help from your friends at KDnuggets you will be able to hone your prompt engineering skills to do useful things like generate code, assist in your research process, and analyze data.
GitHub CLI for Data Science Cheat Sheet
The GitHub CLI, unsurprisingly, is the GitHub tool that allows for interaction with the GitHub platform with the command line interface. Mastering the most-used commands will allow you to become a productive of a development team, be that a web app development team, or more specifically for our purposes, a data science, data engineering, or machine learning engineering team.
Plotly Express for Data Visualization Cheat Sheet
The cheat sheet first addresses getting started, such as installing the library and its basic syntax. Next, the resources covers creating common chart types with Plotly Express, including: Scatter plot, histogram, density heatmap, pie chart, box plot. Finally, you will gain some exposure to plot customization, including adjusting markers and layouts.
Getting started with cuDF is straightforward, especially if you have experience using Python and libraries like Pandas. While both cuDF and Pandas offer similar APIs for data manipulation, there are specific types of problems in which cuDF can provide significant performance improvements over Pandas, including large scale datasets, data preprocessing and engineering, real-time analytics, and, of course, parallel processing. The bigger the dataset, the greater the performance benefits.
ChatGPT for Data Science Interview Cheat Sheet
Mastering data science interviews are a skill all their own, and preparing for them is the key to success. Just as I was once told that learning how to write university examinations is a skill all of its own, beyond learning the material on which you are being tested, specialized technical job interviews are very similar.
10 ChatGPT Plugins for Data Science Cheat Sheet
For an overview of what we believe to be the 10 of the best ChatGPT plugins for data science, check out our latest cheat sheet, conveniently named 10 ChatGPT Plugins for Data Science Cheat Sheet. You’ll find plugins for coding, analysis, web searching, document interrogation, and more.
Streamlit for Machine Learning Cheat Sheet
Putting machine learning and Streamlit together is a popular option for data scientists and other data professionals looking to experiment on data, prototype, or share results. Knowing how to quickly turn around data apps is becoming an essential skill for data folks, and this combination certainly allows for this. If you don’t know how to use Streamlit, we suggest you learn now.
Machine Learning with ChatGPT Cheat Sheet
With ChatGPT, building a machine learning project has never been easier. By simply writing follow-up prompts and analyzing the results, you can quickly and easily train the model to respond to user queries and provide helpful insights. In this cheat sheet, learn how to use ChatGPT to assist with the following machine learning tasks: Project planning, feature engineering, data preprocessing, model selection, hyperparameter tuning, experiment tracking, and MLOps.
Scikit-learn for Machine Learning Cheat Sheet
Scikit-learn’s unified API interface makes learning how to implement a variety of algorithms and tasks much easier than it would otherwise be. Once you learn the pattern of how to make Scikit-learn calls, you are off and running. The only thing you need after this, beyond your imagination and determination, is a handy reference. This cheat sheet covers the basics of what is needed to learn how to use Scikit-learn for machine learning, and provides a reference for moving ahead with your machine learning projects.
Docker for Data Science Cheat Sheet
Docker has become an essential data science tool to assist in the building of reproducible and scalable environments. Docker allows code and dependencies to be packaged in containers, which lets data scientists distribute their models across different platforms. This assists in both development and production, and works to prevent errors and inconsistencies that can arise from different versions of software or hardware configurations.
Getting Started with Graph Database Queries Cheat Sheet
In graph queries we lose some syntax from SQL and gain other syntax. SELECT has been replaced by MATCH. FROM and JOIN have been discarded. But the WHERE and ORDER BY commands are used in the same way. Aggregate functions like SUM and AVG are all there, but the GROUP BY has been discarded. Most importantly, though, we gain the ability to query patterns in the graph using the node relationships. In the attached Cheat Sheet, you will see a list of most-commonly used query approaches.
Data Cleaning with Python Cheat Sheet
In this cheat sheet, we go from detecting and handling missing data, dealing with duplicates and finding solutions to duplicates, outlier detection, label encoding and one-hot-encoding of categorical features, to transformations, such as MinMax normalization and standard normalization. Moreover, this guide exploits the methods provided by three of the most popular Python libraries, Pandas, Scikit-Learn and Seaborn for displaying plots.
Python Control Flow Cheat Sheet
The state of flow control has come a long way since the days of goto. There are numerous common execution patterns that are available in the majority of modern programming languages, though their syntax differs from language to language. Python has its own, generally quite readable, set of flow controls, and that’s what our latest cheat sheet focuses on. Get ready to learn flow control, and to have a handy reference moving forward as you conquer the world of coding.
AI Chrome Extensions for Data Scientists Cheat Sheet
The selection of tools presented on this cheat sheet includes SciSpace Copilot, an AI-powered research assistant designed to help you understand the text, math, and tables in scientific literature. Fireflies, an AI assistant powered by GPT-4, is also featured. This revolutionary tool can surf the web and summarize various types of content, including articles, YouTube videos, and emails, with human-like efficiency. And more.
Best Python Tools for Building Generative AI Applications Cheat Sheet
Some highlights covered include OpenAI for accessing models like ChatGPT, Transformers for training and fine-tuning, Gradio for quickly building UIs to demo models, LangChain for chaining multiple models together, and LlamaIndex for ingesting and managing private data. Overall, this cheat sheet packs a wealth of practical guidance into one page. Both beginners looking to get started with generative AI in Python as well as experienced practitioners can benefit from having this condensed reference to the best tools and libraries at their fingertips.
With LangChain, developers can build capable AI language-based apps without reinventing the wheel.
