Final challenge / assignment for the Udemy course: Feature Engineering for Machine Learning

Assignment:

Beat the performance of my Lasso regression by using different feature engineering steps ONLY!!.

The performance of my current model, as shown in this notebook is:

test rmse: 44798.497576784845
test r2: 0.7079639526659389

To beat my model you will need a test r2 bigger than 0.71 and a rmse smaller than 44798.

=====================================================================

Conditions:

• You MUST NOT change the hyperparameters of the Lasso.
• You MUST use the same seeds in Lasso and train_test_split as I show in this notebook (random_state)
• You MUST use all the features of the dataset (except Id) - you MUST NOT select features

======================================================================

If you beat my model:

Make a pull request with your notebook to this github repo: https://github.com/solegalli/udemy-feml-challenge

How to make the PR

1. fork the repo:

Go to https://github.com/solegalli/udemy-feml-challenge, and click on the fork button at the top-right

2. clone your forked repo into your local computer:

• Go to www.github.com/yourusername/udemy-feml-challenge
• Click the green button that says clone or download
• copy the url that opens up
• Power up a git console
• Type: git clone (paste the url you copied from github)
• done

3. Make a copy of the jupyter notebook and add your name:

• Open up the Jupyter notebook called 13-Assignement.ipynb
• Click the "File" button at the top-right and then click "Make a copy"
• Work your solution in the Copy and not in the original assignment (otherwise there will be conflicts when making the PR)
• Change the name of the copy of the notebook to: 13-Assignement_yourname.ipynb
• Done

When you finish, just commit the new notebook to your fork and then make a PR to my repo

But I have a notebook ready and I haven't cloned the repo yet, how can I make the PR?

If you worked in the copy you downloaded from Udemy before forking and cloning this repo, then follow this steps:

1. fork the repo:

Go to https://github.com/solegalli/udemy-feml-challenge, and click on the fork button at the top-right

2. clone your forked repo into your local computer:

Go to www.github.com/yourusername/udemy-feml-challenge

• Click the green button that says clone or download
• Copy the url that opens up
• Power up a git console
• Type: git clone (paste the url you copied from github)
• Done

3. Rename your solution as follows and copy it into your cloned repo:

• Rename your solution notebook to: 13-Assignement_yourname.ipynb
• Copy this file into the cloned repo
• Done

When you finish, just commit the new notebook to your fork and then make a PR to my repo

Good luck!!
