- 3. CHALLENGES? Privacy Problem Can entities train model without disclosing data? Influence problem Can 3rd parties contribute towards behavior of AI model in a way that is quantifiably influential? Economic Problem Can 3rd parties be correctly incentivized to contribute to knowledge & quality of AI models? Transparency Problem Can the activity of behaviour of AI model be transparently available to all parties without a trusting middleman? Latency Problem Centralized AI is inappropriate for use-cases where AI needs to interact in real time with the real world
