GemNet: Menu-Based, Strategy-Proof Multi-Bidder Auctions Through Deep Learning

Understand

Automated mechanism design (AMD) uses computational methods for mechanism design.

• Differentiable economics is a form of AMD that uses deep learning to learn mechanism designs and has enabled strong progress in AMD in recent years.
• Nevertheless, a major open problem has been to learn multi-bidder, general, and fully strategy-proof (SP) auctions.
• We introduce GEneral Menu-based NETwork (GemNet), which significantly extends the menu-based approach of the single-bidder RochetNet (D\"utting et al., 2024) to the multi-bidder setting.
