Google Research introduced Agile Deliberation, a framework that treats building subjective AI image classifiers as an iterative conversation in which the system helps users sharpen their own definitions before training. The work addresses a gap in standard workflows, which assume a labeler already holds a clear, stable definition of a category, an assumption that fails for concepts like healthy food or inspiring artwork whose boundaries shift with culture and policy. Agile Deliberation splits the task into concept scoping, where a broad idea is broken into sub-categories and explicit exclusions, and concept iteration, where vision-language models surface semantically borderline images that challenge the current text definitions. Human feedback on those edge cases feeds an automatic prompt optimization loop, so the classifier's boundaries move with the user's refined intent. Google Research says it bypassed simulated testing because static benchmarks cannot capture subjective concepts, and instead ran 18 live 1.5-hour sessions with human participants. The team reports the approach reduced user fatigue and anxiety by replacing manual prompt engineering with direct feedback on borderline images, producing more consistent models that outperform standard baselines. The underlying code and algorithms were open-sourced on GitHub.

## Evidence

Verbatim from https://research.google/blog/agile-deliberation-how-ai-helps-humans-define-the-gray-areas/:

> Agile Deliberation addresses the challenges of building AI image classifiers for subjective categories by guiding users through an interactive deliberation workflow, from scoping sub-categories to resolving edge cases, using an LLM-driven optimization loop to automatically build an accurate, aligned classifier.

> Machine learning models learn to recognize the world around us from examples labeled by humans. Underlying this process is an assumption that the person doing the labeling has a clear and stable definition of the category in mind before they begin. This assumption holds well when training a model on objective categories, like a stop sign or a golden retriever, where boundaries are clear and universally recognized. In practice, however, real-world applications often require vision systems to navigate the subjective "gray areas" of human experience. For example, consider training a vision classifier to identify "healthy food", curate "inspiring artwork”, or assist in content moderation. In such domains, category boundaries may not be universal or static, since they can shift with cultural context, personal philosophies, or evolving operational policies.
