Core Problem & Solution - Vertical AI applications face a "last mile problem" in understanding industry-specific context and workflows, which is more critical than model sophistication [4][6] - Anterior proposes an "adaptive domain intelligence engine" to convert customer-specific domain insights into performance improvements [17] - The engine consists of measurement (performance evaluation) and improvement (iterative refinement) components [17] Measurement & Metrics - Defining key performance metrics that users care about is crucial, such as minimizing false approvals in healthcare or preventing dollar loss from fraud [18][19][20] - Developing a failure mode ontology helps categorize and analyze different ways the AI can fail, enabling targeted improvements [21][22] - Combining metric tracking with failure mode analysis allows prioritization of development efforts based on the impact on key metrics [26][27] Iteration & Improvement - Failure mode labeling creates ready-made datasets for iterative model improvement, using production data to ensure relevance [29] - Domain experts can suggest changes to the application pipeline and provide new domain knowledge to enhance performance [32][33] - This process enables rapid iteration, potentially fixing issues the same day by adding relevant domain knowledge and validating with evals [37] Domain Expertise - The level of domain expertise required depends on the specific workflow and optimization goals, with clinical reasoning requiring experienced doctors [38][39] - Bespoke tooling is recommended for integrating domain expert feedback into the platform and workflows [41] - Domain expert reviews provide performance metrics, failure modes, and suggested improvements, all in one [38] Results & Performance - Anterior achieved a 95% accuracy baseline in approving care requests, which was further improved to 99% through iterative refinement using the described system [14][15]
