3 inequalities for good models 👌

Guidelines for good models, that often hold true.

3 VS Code Snippets, to make writing in Quarto even easier! 🔨

Today, I bring you something hands-on: 3 snippets to implement figures in Quarto with ease. Cross-referencing, captions and all. These 3 snippets include: r-figure, r-figure-subplot2 and r-figure-subplot3. You can find them at the end of this article.

Ask better questions

If you are working on the wrong problem, the quality of even the best neural networks, probabilistic and gradient boosted models would be useless. However, in data science, it is assumed that the problem being worked on is always clear. It is not.
