Developing computer vision (CV) products involves an exciting initial phase where early demos showcase the potential of machine learning models, but the real challenge lies in transitioning from proof-of-concept (POC) to production. While initial successes might lead to overconfidence, a rigorous assessment of machine learning models, including testing for robustness, bias, and data quality, is essential to avoid common pitfalls such as over-promising capabilities, resource wastage, and collecting inadequate data. Many AI projects falter in this transition, with 53% never reaching production, often due to insufficient attention to model robustness, inadequate data quality, and a lack of understanding among stakeholders about the model's limitations. Implementing comprehensive testing protocols early in the development process can mitigate these issues, ensuring that data and model performance align with specific use cases. Tools like Lakera's MLTest facilitate these assessments by providing automated insights into model performance and data quality, ultimately paving the way for more successful deployments.
