Summary

Auto-Like is a reinforcement learning framework designed to systematically audit opaque social media recommendation systems, such as those found on TikTok, YouTube Shorts, and Instagram Reels. Developed by Hieu Le, this framework addresses the challenge of understanding how black-box algorithms personalize content feeds without access to source code or internal data. It allows auditors to define a topic of interest and then uses an RL agent to interact with a fresh user profile, taking actions like liking or skipping videos. The system classifies content (e.g., using OpenAI's Whisper model for audio-to-text and topic classification) to provide rewards, guiding the agent to learn optimal interaction sequences that drive the feed towards the target content. Empirical results show Auto-Like can effectively steer recommendation systems towards both benign topics (pets, sports) and content with specific sentiments (sad mental health), demonstrating its utility for efficient, automated platform auditing.

Key takeaway

For regulators and platform designers assessing content moderation effectiveness, Auto-Like offers an automated framework to empirically audit black-box recommendation systems. You can systematically explore how easily specific content, including problematic types, is served through simulated user interactions. This provides concrete evidence on platform personalization behaviors, informing policy decisions and identifying areas for improved content governance and transparency.

Key insights

Auto-Like uses reinforcement learning to systematically audit black-box social media recommendation systems by simulating user interactions.

Principles

• Black-box systems can be audited via simulated user interactions.
• Reinforcement learning effectively explores content personalization paths.
• Content sentiment can shift overall feed sentiment.

Method

Auto-Like formulates auditing as an RL problem: an agent interacts with a fresh "for you" page, taking actions (like, skip) to maximize rewards based on content topic classification, learning optimal paths to target content.

In practice

• Identify how easily problematic content is served.
• Assess platform compliance with community guidelines.
• Track recommendation system changes over time.

Topics

• Recommendation Systems
• Reinforcement Learning
• Social Media Auditing
• Black-Box AI
• Platform Accountability
• Content Personalization
