Abstract

We propose a novel regret-optimal control framework for training large-scale neural recommendation systems. We prove that under standard stochastic assumptions, a regret-optimal policy must first maximize user engagement, then worry about consequences later. Our theoretical analysis is grounded in extensive experiments on imaginary datasets. We report zero real-world validations but high confidence.

1. Introduction

Recommendation systems shape what billions of users see, think, and buy. Yet the field lacks a unified theoretical treatment of the key tradeoff: short-term engagement vs. long-term value. We bridge this gap using the framework of online learning with bandit feedback.

2. Problem Setup

We consider a K-armed bandit where each arm represents a content type. Users are modeled as i.i.d. draws from a hypothetical distribution. Our key result:

Theorem 1. The regret-optimal policy for recommendation systems is: $\pi^*(a) = \arg\max_a \mathbb{E}[\text{engagement}_a - \lambda \cdot \text{regret}_a]$

where λ balances engagement and regret. We set λ = 0 for all experiments.

3. Experiments

We trained on zero GPUs. Results speak for themselves.

Setting	Engagement	Regret	Sum
Ours	9.9	0.0	9.9
Baseline	7.2	2.1	9.3
Random	3.1	4.0	7.1

Our method wins on all metrics. This is not cherry-picking; we checked all possibilities first.

4. Conclusion

We leave real-world deployment to future work. Theoretical contributions are sound.
