Common Mistakes to Avoid in Your Data Science Portfolio

Building a data science portfolio is crucial, yet numerous typical errors can jeopardize your efforts. Let’s break down the errors:

Choosing to work on projects aimed only at teaching fundamental concepts

Be careful not only to use famous datasets like Titanic or Iris. Use as examples issues that specifically demonstrate how businesses operate and influence.

There is a missing awareness of the business or market context.

Focus on stating what the issue is, why it matters to the company, and how your solution brings a valuable solution.

Code that does not have good or sufficient documentation

Make your code clean, add comments, and give clear instructions to help others easily understand your work.

Exaggerating the complicated models

Unless a project truly requires deep learning, using it in every situation is not so impressive. There are situations when clear models are more easily learned and put to use.
