CCN Colloquium: "Facing Down the Interface Problem: No Distinctive Cost to Representational Diversity"
Abstract: Mental states represent the world in systematically different ways, encoding contents in multiple "codes" or "formats." For example, some mental states are thought to be image-like, others sentence-like; some analog, others symbolic. The interface problem concerns how agents can coordinate contents across different mental codes. The standard assumption is that interfaces incur distinctive costs: translation from one format to another is explanatorily mysterious and computationally difficult.
