Detailed Technical Algorithm for a TikTok-like Recommendation System

---

1. Introduction

The objective is to develop a recommendation system that maximizes user engagement by analyzing a multitude of user interaction signals to present the most appealing content. The system optimizes for two key metrics:

• User Retention: Encouraging users to return to the platform.
• Time Spent: Increasing the duration users spend on the platform per session.

// BAD - or what I call draft; comments explain what instead of code being self-explanatory
// Main bit
const formConfig = fieldArray.reduce((fields, field) => {
  if (!Array.isArray(fields)) {
    field = [field];
  }

  // Currently last field in section
  const last = fields.slice(-1)[0],

Important: I'm writing this when the last version of macOS (and the one I have installed) is Mojave. There is already a script which installs Mojave in a virtual machine here https://github.com/img2tab/okiomov. But if you are curios how to do everything manually to install High Sierra, then this guide may be useful.

After reading a few articles I ended up with these steps:

1. On macOS, download the High Sierra installer (even if you have Mojave installed): https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?ls=1&mt=12
2. If the High Sierra Installer starts, quit it.
3. Open "Disk Utility".
4. Click on "File" > "New Image" > "Blank image...". Or just press cmd+N.
