Will I benefit from an independent model assessment?

3 minThe team has built an AI model and performance appears adequate. But there is a lot riding on the deployment. Do I need independent model test and evaluation? When is the cost justified? Many AI Engineering teams, especially newer ones, often fail to realize the many ways in which bias and performance limits can

Is AI testing like software testing?

There’s much similarity between testing applied AI/ML (For brevity, I’ll just refer to these as “AI”) applications and traditional software[1]. Regardless of the vertical and the type of model and architecture, these similarities have worked in the industry’s favor as traditional software CI/CD processes and technologies have readily embraced AI applications with a plethora of
