| You are developing a recommendation system for a financial platform that predicts | |
| whether a user will click on a merchant offer. The dataset contains interactions | |
| between users and merchant offers, including features such as user ID, merchant | |
| offer ID, timestamp of interaction, and a binary label indicating whether the user | |
| clicked on the offer (1 for click, 0 for no click). | |
| Additionally, it contains the past history of the user's click through rate (measured | |
| by number of clicks over total impressions over the time period specified). Each | |
| view/click is measured once per session, meaning if a user clicked on an offer multiple | |
| times, it would only be counted once. |
Storing/sharing large PDFs can be cumbersome. What if we could trade off some quality to save some space? This is exactly the idea behind (lossy) compression.
You can install ghostscript (gs) via the official site,
via homebrew brew install ghostscript (on MacOS), or nix-shell using the shell.nix

This is a barebones setup to using TeX with matplotlib. Since the whole MacTeX package is ~4GB, and includes a lot of unnecessary binaries, it is better to install BasicTeX and install the packages as you seem fit.
The easiest way to install is by running brew cask install basictex and run which pdflatex to check whether it is installed. This should return a path with the location of the filepath. If it doesn't, then check if the /Library/TeX folder exists.
Finally, add the following to your ~/.bashrc or ~/.bash_profile filepath: export PATH="/Library/TeX/texbin/:$PATH"
This is a small tutorial on how to install custom matplotlib fonts (on OSX) in each environment seperately.
First, we need to install our custom fonts. Note: Matplotlib expects a font in True Type format (.ttf). For example, if we want to add the Helvetica font, we need to check if we have the font in .ttf format installed on our system otherwise we need to download it and install it.
One easy way to install fonts (with .ttf extension) is to use 1001fonts. Search for the font you want, and download away.
